[exotic pumice]

yeah, jk

anyways, good night

[raven canopy]

i know. you too! 💤

[exotic pumice]

thanks

[river quest]

@umbral dagger soon it will be matter of when, not if....

once we get some buttons and some more things going, some stacks will be possible with sound, menus, etc...

[umbral dagger]

PyCard

[river quest]

LCARS alarm clock lookin good

[umbral dagger]

PyperCard

[river quest]

haha

[umbral dagger]

I have a better pallette on it now.

Alarm works (including touch to stop it)

[river quest]

with stemma port could do something like get heart rate and not turn off alarm until it's beating more

hehe

or it donates to something each time you hit snooze

gotta use that IoT for somethin'

[umbral dagger]

It monitors the light sensor and dims the backlight when the light is low

[river quest]

that's a nice feature that not even most alarms clocks do it seems

this one can do that, set the time automatically, etc too

[umbral dagger]

Yes, time is fetched. based on the event count down demo

[river quest]

single serving countdown clocks are fun

[umbral dagger]

Thinking of using the switch connector to add a large arcade button for snooze.

[river quest]

yep 😃

[umbral dagger]

And there's a spot on the screen for a weather icon.

[river quest]

oh, we just committed the code for openweathermap

....

[umbral dagger]

Cool.. I was looking for it 😃

[river quest]

just got done testing and made new graphics

been working all night, it's really handy

[umbral dagger]

I'll add that in, then add a second mode for setting the alarm. All touchscreen based.

[river quest]

er, travis just finished, it will be up in a sec

[umbral dagger]

I'll grab it tomorrow. Callign it a night.

[river quest]

ok! https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/PyPortal_OpenWeather

same here, time to zzzzz tooo

[simple mantle]

so a friend of mine is doing microcontrollers and hardware engineering at school. he has a project idea for his first term assignment. I would like to make this as a prototype using circuitpython (my friend is forced to use C) just to show him that it can easily be done.
The idea is to measure the ground temperature and gps location on the road and analyze this data. Im thinking featherwing + gps thing + IR temp sensor. with future option to expand into something like a gsm module to live stream the data to an iot backend. ideas of what hardware is needed? I have a featherwing datalogger hence my initial thought off using it, but that does not matter if there is other options. (already asked in the python discord)

[main meteor]

I don't know of any IR temperature sensors with CP support offhand. Here's one I2C unit that might be suitable, I doubt it would be too tough to write a module to talk to it https://www.dfrobot.com/product-1495.html

[tidal kiln]

there are CP drivers for both the TMP006 and TMP007:
https://github.com/adafruit/Adafruit_CircuitPython_TMP006
https://github.com/adafruit/Adafruit_CircuitPython_TMP007

[solar whale]

but both are discontinued 😦

[tidal kiln]

hmm. still some 006's avail:

fwiw

[prime flower]

@gilded cradle Could you ping me when you've made the change to ESP32SPI, or add me to review it so I can see if it affects the _IO library?

[gilded cradle]

Yeah, was just going to put in both PRs at the same time

[prime flower]

ok, no problem

[gilded cradle]

Just hoping to finish before my laptop dies

Since I forgot my charger

[prime flower]

Doesn't look like the .mpys for IO CircuitPython were added to the 1.0 release. Travis shows they were built (https://travis-ci.com/adafruit/Adafruit_CircuitPython_AdafruitIO/builds/102205219#L411)

[idle owl]

@prime flower Because Travis failed to deploy. Needs an API key. I don't think I got around to adding it.

Yeah, I'll do that now.

[prime flower]

Thanks kattni!

[gilded cradle]

I got both PRs in @prime flower . Laptop is at 5%, so phew.

[prime flower]

PHEW, I'll test on IO and submit PRs with the changes

oh wow you already did it, thanks

[idle owl]

API key added. Restarted the 1.0 build, should deploy. Please verify it once the build is done, I'm in the middle of a lot of things.

[prime flower]

Will do.

[gilded cradle]

Ok, down to 3%, so shutting down.

[pastel panther]

lets try this again. heya @tulip sleet what does it mean for memory in CP to be 'long lived'?

[tulip sleet]

The heap memory is divided into long and short-lived for garbage collection reasons. One is allocated from one end of the heap, one from the other. The idea is to group long-lived stuff together so it's not mixed with short-lived stuff, to reduce fragmentation. An added thing is that short-lived memory may be relocated during a gc, but long-lived is not.

[pastel panther]

excellent! Thanks

[simple pulsar]

@tulip sleet Is that duty_cycle thing a known issue, btw?

Not important, I'm just curious

[pastel panther]

@tulip sleet I feel like I've also seen a few places with malloc'd memory without an associated (or at least nearby) free. Is that some CP magic?

[simple pulsar]

Although it's an unusual kind of bug so there might be some unpleasantness going on under the covers

[tulip sleet]

no, first we heard of it. I looked at the code and maybe we're not operating the peripheral quite correctly. The code is different on samd21 and '51. We have to wait for the TC or TCC to be ready in some cases.

hold on phone call

[prime flower]

@gilded cradle I think my prev. commit to your master messed up the history (adding to remote PRs is weird..)

was trying to add an updated analogin example since it wasnt included

[gilded cradle]

Ok, I wondered if something like that might happen

[prime flower]

I think it's because I was in a detached HEAD, you can try to drop that commit by rebasing the PR

[gilded cradle]

Um, I’m not sure how to do that.

[pastel panther]

https://www.atlassian.com/git/tutorials/merging-vs-rebasing

[gilded cradle]

Thanks

Ugh, laptop won’t boot. I’ll have to do it later.

[prime flower]

@gilded cradle I reverted the incorrect merge

[tulip sleet]

@pastel panther there is no free because the garbage collector takes care of it

[prime flower]

'git pull' your 'master' before making more edits, so it doesnt encounter a merge issue

also for the future - when adding a PR, make a branch called new-features or update-examples. Create a pull request from the branch, so it doesn't effect the history of master

[pastel panther]

proceeds to malloc with abandon

[gilded cradle]

Ok, thanks @prime flower

[prime flower]

@gilded cradle changes look good, ready for me to approve and merge?

[gilded cradle]

Yeah

[prime flower]

🎉 done

[gilded cradle]

Thanks

[tulip sleet]

@pastel panther use the other peripheral calls to storage allocaters as a guide, because you may want to call malloc by a different name.

[gilded cradle]

Mind if we do a release @prime flower?

[prime flower]

I'm about to @gilded cradle

[gilded cradle]

Perfect

[prime flower]

Was waiting to see if jerryn would approve the other PR so I could do them at once, but its ok to do 2 seps.

drafting...

[gilded cradle]

Yeah, either way is fine

[prime flower]

@gilded cradle Released

[gilded cradle]

Thanks.

Can we change the semver to something like 1.1.0 so it matches the rest of the repositories @prime flower?

[idle owl]

I'm not certain you can simply change the version number. You may have to do another release, or delete the current release. But you'll have to skip the current number or you can end up with things colliding. So jump to 1.2.0 or something.

[prime flower]

@gilded cradle I could bump to 1.2.0 after the current PR is pulled in for precision if that works, otherwise I can delete and do another release jumping to 1.2.0

[crimson ferry]

Today's Adafruit_CircuitPython_ESP32SPI changes get rolled into tomorrow's Adafruit_CircuitPython_Bundle auto-release?

[meager fog]

@pastel panther hihi i have a Q about the BMP decoding

[pastel panther]

yes?

[meager fog]

is there such thing as 32-bit BMP?

[pastel panther]

I think GIMP thinks so

looks

[meager fog]

ok i mhave a 'not viewing' bmp maybe you can look

i dont know what its deal is

i have no idea what 32 bit would mean tho

[pastel panther]

gimp sez yes

[meager fog]

is there an alpha channel???

[pastel panther]

ARGB or XRGB

yes (not sure what X is)

[meager fog]

alpha i guess

can you look at if we can add support for it while you're in the 8 bit zone

[gilded cradle]

Yeah it’s alpha, was doing som bmp stuff for ra8875 yesterday

[pastel panther]

sure thing

[meager fog]

In the original OS/2 DIB, the only four legal values of color depth were 1, 4, 8, and 24 bits per pixel (bpp).[4] Contemporary DIB Headers allow pixel formats with 1, 2, 4, 8, 16, 24 and 32 bits per pixel (bpp).[17] GDI+ also permits 64 bits per pixel.[18]

ok we'll just drop alpha for now

so skip that byte

here's another one

i dont think its a big code challenge cause we'll just skip the data and treat the rest as RGB

but take a look!

i've never bumped into 32-bit but this one website seems to generate em

[pastel panther]

should be straightforward

[gilded cradle]

@prime flower that works for me

[main meteor]

Some screen grabbing programs seem to create 32 bit ones for some reason.

[gilded cradle]

@crimson ferry, that’s correct though you could just grab it right out of the repo now.

[crimson ferry]

@gilded cradle Thanks, it took me a bit to figure out where to grab it. But just tested and it works great on my ItsyBitsy-ESP32 testbed. I really appreciate the changes! Added DotStar import to my local examples + changed ESP pin names to numbers (suspect they're not defined for ItsyBitsy). Awesome! 😃

[gilded cradle]

Glad to hear. I thought it was a great suggestion.

[prime flower]

@gilded cradle bump'd https://github.com/adafruit/Adafruit_CircuitPython_AdafruitIO/releases/tag/1.2.0

[gilded cradle]

Awesome. Thanks brent

[prime flower]

@gilded cradle if you decide to do that RSSI issue, be warned that rssi returns an unpacked struct and needs to be "prettified"/cleaned up in the signal_strength method would be abstracting ._esp.rssi (I just messed with it quickly)

[umbral dagger]

Is there any reason the PyPortal splash group is set to max=5??

[main meteor]

Once I've loaded a new bitmap font, how do I use it?

[pastel panther]

@prime flower you may be entertained to know that the aforementioned mushroom farmer is now doing his own configuration of the AIO feeds and data logging

[prime flower]

@pastel panther omg..the internet of mushroom farming....Can he email [e-mail] with some pictures or at least the dashboard?

[pastel panther]

totes; I got some pix of the grow room but we'll be getting together tonight to finish out some details

[prime flower]

The IO team can't see what people are doing on/with IO, per our IOT Bill of Rights. So it's always interesting to hear/see Adafruit IO use cases

[pastel panther]

thats comforting to know 😃 I'd be happy to send pix/deets and even write a blog article when things are further along

[prime flower]

hopefully he'll figure out some features he wants, we can add blocks/build out features fairly quickly

[pastel panther]

sounds good

I put a TFT FeatherWing on a Feather M4, and when I instantiate ILI9341 (the displayio version), I get a copy of my REPL interactions on the screen. My hat's off to tannewt and the rest of the crew, that's truly spiffy.

[pastel panther]

pretty great, right?

[main meteor]

Indeed. Colour me impressed.

[prime flower]

@main meteor it's super useful 😄

[main meteor]

Now to figure out how to change the font 😃

[simple pulsar]

hello all. Is anyone aware of any code in CircuitPython which manipulates a bytearray buffer? The CP implementation is very bare bones with append() and extend() only.

I'm wondering how to (efficiently) manage a bytearray where I need to remove a little bit from the beginning

>>> del B[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'bytearray' object does not support item deletion

😦

[main meteor]

Use slice notation? ```python
B[1:]
bytearray(b'\x05\x06\x07\x08\t')

[simple pulsar]

I'd like to efficiently modify an existing one

[tulip sleet]

The internal storage doesn't allow trimming off the front, I believe, so you'll need to copy one way or another

[simple pulsar]

bytearray(b'\x04\x05\x06\x07\x08\t')
>>> B = B[2:]
>>> B
bytearray(b'\x06\x07\x08\t')

[tulip sleet]

is array.array of bytes more functional for you?

that's why various read and write functions take boundaries for buffers so you can do partial reads or writes

[simple pulsar]

I'm buffering up some MIDI data. I was thinking of holding a certain amount of it in the MIDI class.

What do you think is best, I've not looked at array.array. Is that going to be bigger because it's int rather than bytes?

[tulip sleet]

could you just keep start and stop indices, or do a circular buffer?

array.array is what type you say: it could be bytes, 16-bit words, or 32-bit-words

[simple pulsar]

I was pondering that but thought I'd start simple!

[tulip sleet]

you could keep a list of bytes or byte arrays and join them at the end. b''.join(...) is the "efficient" way to concatenate

(assuming that works, haven't tried it)

[simple pulsar]

ok, i'll start with just over writing with slices and leave a note to revisit it if memory/performance is grim

thanks for the ideas

[raven canopy]

@tulip sleet do you have a moment, or are you heads-down on something? have some "general" tinyUSB questions

[tulip sleet]

ga

[raven canopy]

k. first, is it more sensitive to interrupts than the AS4 stack was?

[tulip sleet]

You mean the ASF4 stack messed up? They should be similar, in the sense that it shouldn't bother them. We set USB prio fairly low. On nrf, in particular, Bluetooth gets priority over everything else, because it's very timing-sensitive

[raven canopy]

well, now that i'm compiling without error again, as soon as my one TC with an overflow interrupt is enabled, the board locks up and then the USB gets hosed.

[tulip sleet]

in other words, FrequencyIn might not work very well on nRF, if it were implemented for it.

[raven canopy]

i was on the AS4 stack for the longest...

[tulip sleet]

how often is your interrupt handler running? Is it just runnig on edge transitions? What freq are you testing with?

[raven canopy]

its a TC, in 16bit mode, interrupt occurs on overflow, and its sourced from DPLL1 @ 98.304MHz

its the "reference" TC, and has no interaction with the EIC

[tulip sleet]

so what's the overflow interval?

[raven canopy]

from my understanding: 98,304,000 / 65535 = 1500 clock periods

[tulip sleet]

so 1500 kHz? Is the count always 65535 or does it go down?

so very roughly once a msec

[raven canopy]

always 65535, which is the max counter value in 16bit mode.

[tulip sleet]

looking at your code...

[raven canopy]

let me push the current. anything on my repo is likely really stale. 😄

[tulip sleet]

i was looking at the PR

[raven canopy]

oh..yeah, REALLY stale. 😆

it might be growing penicillin at this point. 🍞

[tulip sleet]

too late to turn into croutons

[raven canopy]

https://github.com/sommersoft/circuitpython/blob/new_freq_in/ports/atmel-samd/common-hal/frequencyio/FrequencyIn.c

[tulip sleet]

@raven canopy in your test setup, have you applied a test signal to the input pin to measure? If so, what is it?

[raven canopy]

nope, no signals were applied when i ran it twice last night. couldn't stomach any more tests, since windows got seriously hiccuped forcing a restart to get the board recognized. i have not ruled out update 1809 as a culprit, either

[tulip sleet]

When it hangs, what does the stack trace show? is it always inside 'frequencyin_interrupt_handler`? It might be worth having that toggle a pin to see what the rate really is.

[raven canopy]

the ones i caught were <signal_handler>, TC4_Handler and shared_timer_handler(0x04).

0x04 being the TC index

[tulip sleet]

but shared_timer_handler calls frequencyin_interrupt_handler, so you might see that some time (it should spend more time there). So it doesn't fail until you start a frequency_in capture? So instrument frequencyin_interrupt_handler to see how often it's being called, and maybe whether bad things are happening inside there (bad ptrs, etc.) You could toggle a pin or increment a counter (and take a look after a few seconds).

[raven canopy]

yeah, i was going to jump into setting some bp's tonight and getting some closer information. just wanted to kind of check if USB would a viable direction to look as well.

thanks for the look, and the "business as usual" expectations on tinyUSB. gotta go cook & eat real quick. will let you know if i find anything interesting.

[tulip sleet]

i think losing usb is an effect, not a cause. You could see if tinyusb is involved by running not connected to USB (toggle the LED or something and see if it hangs)

[raven canopy]

oh, and i kind of blasted straight past your questions in the first part. the "capture" starts automatically, but that doesn't generate any interrupts. the reference TC interrupts, and grabs info from the capture TC(s). and i agree, it should be spending some if not more time in frequencyin_interrupt_handler. it was likely just that i wasn't catching the stack at the right time without breakpoints set.

[umbral dagger]

Added weather display.

The display dims and switches to a red pallete when ambiant light is low.

[gusty topaz]

Nice!

Guys, has anybody here tried out the NanoPi M4 SBC?. I'm wondering if CP and/or Adafruit hardware (bonnets) would work on it:

https://www.friendlyarm.com/index.php?route=product/product&path=69&product_id=234

[marble hornet]

if there is no flash storage does cp support qspi?

i'm not seeing it in the docs

@umbral dagger displayio ?

[main meteor]

Is that weather display code available?

[gilded cradle]

@main meteor maybe at https://github.com/adafruit/Adafruit_Learning_System_Guides/tree/master/PyPortal_OpenWeather

Or a similar folder

[main meteor]

Cool, thanks. Wanted some example code to see how to use fonts. Hmm, gonna have to learn about "groups"

[marble hornet]

can i have some spi sram help? if so hear or #help-with-circuitpython ?

please I'm not quite familiar with spi and cp

[gilded cradle]

Hi @marble hornet. What kind of help did you have in mind? The big RA8875 driver I made is all SPI based.

[marble hornet]

a 128 kb sram chip i have here, http://ww1.microchip.com/downloads/en/DeviceDoc/20005142C.pdf

i can read but it is refusing to write

i'm using the mcpsram lib that comes the the epd lib,

[gilded cradle]

Are you using BusDevice?

[marble hornet]

no, it just handles the spi directly

[gilded cradle]

Take a look at the guide at https://learn.adafruit.com/circuitpython-basics-i2c-and-spi. It helped me out.

Also, is it giving errors or is it just not writing?

[marble hornet]

it's just not writing

i get back the same number no matter what (funny enough not zero)

[gilded cradle]

Ok. I need to head home, but I’ll get back online as soon as I get there. I’ll see if I can come up with any ideas on the way.

Until then, maybe look at the FRAM driver. One of them is SPI based.

[marble hornet]

thank you @gilded cradle

drive safe

[gilded cradle]

Yw

Thanks

[raven canopy]

@marble hornet do you have your code posted anywhere? i can take a peek to see if i can offer any help...

[marble hornet]

yes!

https://github.com/adafruit/Adafruit_CircuitPython_EPD/blob/master/adafruit_epd/mcp_sram.py

[main meteor]

Hmm, having trouble finding out how to get the root group for a display?

[river quest]

@umbral dagger nice work

nice font

it appears to also be cold

stay warm 😃

[raven canopy]

@marble hornet k. looking...

[marble hornet]

@raven canopy i just pass it the busio.SPi object, it should be compatible since it is microchip

i did try adding ```
spi.try_lock()
spi.configure(baudrate=20000000)
spi.write(bytearray([self.SRAM_RDSR, 00000000]))
spi.unlock()

i found the 00000000 from the datasheet on page 10

and thank you

[raven canopy]

@marble hornet what read/write mode are you trying to set in __init__? i can't see 0x43 setting any of the available modes; only 0x0 (byte), 0x80 (page), and 0x40 (sequential [default]). also, there is this note for mode: Bits 0 through 5 are reserved and should always be set to '0'

[main meteor]

I'm getting closer with textareas, but I'm getting the wrong glyphs displayed for some reason.

[marble hornet]

@raven canopy i am trying to set it to bytes (just a presumption that byte mode is correct)

so i figured rdsr is the cmd and all zeros should set it it to byte mode. (i;m also guessing bito is 2^0 and bit7 is 2^7)

[meager fog]

@main meteor whats not showin'

[raven canopy]

@marble hornet ohhh....just realized that link was to the EPD. 🤦

[marble hornet]

yes

most of the infrastructure seemed to match

[raven canopy]

can you put up a gist of what your code looks like? or even just upload it here.

[marble hornet]

https://gist.github.com/TG-Techie/80890ef8ea8e9e2584605c57e906592d

i have only changed init

with underscores

[main meteor]

I set the text to '0123ABCO', and get '&-,èìòç' displayed

[gilded cradle]

Hi @marble hornet , I'm back on and am reading through the datasheet and comparing it to your code.

[meager fog]

thats interesting

wheres your code?

@main meteor

and what font are you using?

[main meteor]

Here's my code. I can upload the BDF font if that's useful

[solar whale]

@meager fog and others interested -- I wonder if it makes sense to pull the official support for the ESP_ATcontrol and move a particle_argon only version of ESP_ATcontrol over the the "Community Bundle" I'll be happy to try to maintain it but I see no reason to maintain the ESP8266 support or to maintain support for external ESP32 boards -- External ESP32's should use ESP32SPI. I think there is a good use for the particle_argon but as it is not an adafruit board, it makes sense to move its support out of the mainstream. It is a very limited use-case at this point and I'm not sure we should encourage its continuation.

[meager fog]

i dont see a need to do that quite yet

@main meteor thats odd it should work

[solar whale]

OK -- I have added the wifi-manager to ESP_ATcontrol -- and it works for the ESP32 but not for the ESP8266

[meager fog]

want to try my font?

i have lotz o f0ntz

[main meteor]

Sure, I'll give it a whirl

That should narrow down if it's a font issue

[raven canopy]

@marble hornet after hand-jamming the numbers, everything looks like it should be working. the bit work looks correct; dean knows that realm better than i do i'm sure. and CS manipulation looks correct. check pins? do you have a logic analyzer to verify the signal?

[marble hornet]

no , I don;t. the odd thing i think is i;m getting numbers back from read, unique to the addrs. i've also tried setting in in sequential. i'll check conns tho

[meager fog]

try that

[main meteor]

Ah, that works correctly, which points to some sort of issue with my font.

[meager fog]

are you using otf2bdf

cause that's a nice bit of software

[marble hornet]

i seem to be getting nonsense!

>>> chip.read(0,12)
bytearray(b'\x00___________')
>>> chip.read(0,12)[1]
95
>>> chip.read(1,12)[0]
0
>>> ```

why would they be different ?

[gilded cradle]

Another idea is to install the SRAM_23LC library for arduino and see the specific registers that it is using for that chip.

[marble hornet]

i'll give it a shot

[pastel panther]

pro tip: make sure your variables can hold the range of values you expect without overflowing 🤦

turns out zero length buffers aren't very useful

[marble hornet]

hrmmmm

interesting

let me type it up

[raven canopy]

@pastel panther nah. persistence will fix that. keep feeding that zero length! it'll grow! 😄

[main meteor]

These are some old X11 PCF fonts I found somewhere in 2001 and converted to BDF in 2002. Sure enough, it looks like they have some weird encoding I haven't seen before (it's not EBCDIC, Baudot, or Fieldata).

[raven canopy]

debating on another round of USB hosing fun... might as well. 😬

[pastel panther]

weee

[marble hornet]

so the arduino sketch write "The MattairTech MT-D21E is a development..."
so after running it i thought i would check for those bytes in the ram.

1. byte moe for read seems not to work i always gives 0,x,x,x,x,x,x,x,x,x, no mater what. sequential seems to work
2. in sequential if i read(), 12) i get bytearray(b'\x00The Mattair')

[main meteor]

A little poking around reveals they're probably from the ancient x3270-x11 package.

And sure enough, here's the encoding http://x3270.bgp.nu/Charset.html Wow.

[pastel panther]

hey @main meteor Have you ever head of 8bpp bitmaps without a palette?

[main meteor]

Other than greyscale?

[pastel panther]

yea. I mean I suppose it could be 2:2:2 or something..

[marble hornet]

I'm gonna poke around in the c code from arduino and see if i can make sense of it anymore 😉

[pastel panther]

I think some rando online converter made it:

I'm content to not support them, at least for now

[raven canopy]

@marble hornet in Byte mode, to read anything more than a single byte i'm fairly certain you'll have to toggle CS and send the address again. in sequential, the chip will just keep feeding data until CS is pulled high.

and, i think in the EPD, it is setting the mode to Sequential with 0x43. i just don't know why the 3 is at the end of that value.

[marble hornet]

in bytes wont the cs toggle if read is called again b/c it will be high form the last one ?

maybe the other chip needs 0x03 there ?

[raven canopy]

could be? i couldn't find which one is used on the EPD. but i didn't dig too deep.

[marble hornet]

IT"S WORKING !

it sent 0x40

idk why 1<<6 didn;t cut it but 🤷

but it is a little off

hrm, it is writng, now to figure out exactly how

[pastel panther]

working but off is still working! I've got the bitmaps to prove it!

[raven canopy]

@marble hornet 🎉 solving the puzzle is why we love this stuff, right? just starting on my headache for the night... 🐧

[marble hornet]

penguin?

[raven canopy]

its my spirit animal. #FightClub

[marble hornet]

and i think the chips are different, this one has some command differences in addr and addr length

[main meteor]

Tried my code with my handmade HP2647A font and it worked fine. It's weird and wonderful seeing the ancient HP characters on the TFT display.

[marble hornet]

nice! what are you settling in to tackle?

[raven canopy]

FrequencyIn, as always. hehe

[marble hornet]

best of luck

look:

>>> chip.write(0,[x + 1 for x in range(20)])
>>> chip.read(0,20)
bytearray(b'\x00\x00\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f\x10\x11\x12\x13')```

the first two are missing, interesting ...

[umbral dagger]

@marble hornet displayio, yes. Directly and through pyportal.

@river quest Thanks. Font is Anton-regular. -9C is reasonable for this time of year. The -20 cold snaps.. not so much. BTW, winter is the best time to be working at home 😃

[main meteor]

Working with the HP font: it is a thing of beauty

[pastel panther]

niiiiice

[main meteor]

I am becoming quite fond of displayio

[pastel panther]

I should see if I can scare up some TOS/GEM fonts

[umbral dagger]

‘Night’ mode. It looks way brighter than it really is.

[main meteor]

Slick! Yeah, these screens are tricky to photograph.

[pastel panther]

I have a photographer friend who makes the big bucks by taking super awesome pictures of lighting installations; blows my mind

[raven canopy]

waiting on re-build. forgot to flip that silly -flto back off when i updated

[main meteor]

My sweetie used to work at a photo lab taking pictures of difficult-to-photograph things (like chemistry glassware) for brochures. I should ask for tips.

[raven canopy]

@main meteor @umbral dagger those do look gorgeous!! 👏

[main meteor]

I'm pretty sure dastel's is running on a PyPortal, mine's running on a TFT Featherwing.

[raven canopy]

at either rate, that font is looking delicious.

[pastel panther]

if someone were to perfect green phosphor ghosting on a tft, I would give them some money

[main meteor]

It would be fun to try porting Cathode or retro-term to it 😃

[pastel panther]

well this is groovy
https://www.youtube.com/watch?v=jWx7REAQ2MY

[umbral dagger]

Looks like the Cathode app

Ah ya/... I have cool retro term, actually. Duh. Cathode on MacOS is really nice, too.

[pastel panther]

@gilded cradle you might find this useful if you're still doing bitmap stuff

[umbral dagger]

OK, it's late enough that I'm only reading half of what's in front of me. Tomorrow I'll be digging into teh touchscreen. Then the alarm setting mode.

[gilded cradle]

Thanks @pastel panther. I'll take a look. I got 16, 24, and 32-bit working great. I may try and tackle 8-bit.

Ok yeah, I see it's grabbing palette info. Thanks

[pastel panther]

The wording of the palette calcs is a little misleading but the info's there

[gilded cradle]

Yeah

Did you get the other bit formats working too?

[pastel panther]

this page was a revelation:
http://www.ece.ualberta.ca/~elliott/ee552/studentAppNotes/2003_w/misc/bmp_file_format/bmp_file_format.htm

i just got 8bpp indexed working, going to fix the 32bpp weirdos Limor was asking about then on to monochrome

[gilded cradle]

Yeah, I found that yesterday, but hadn't had a chance to read over it

[exotic pumice]

have any of you guys looked into gifs yet? I tried writing a gif loader and it kept bugging out

[pastel panther]

not yet; once BMPs are fleshed out jpegs are next in terms of images

[gilded cradle]

No, I was trying to tackle the easy ones

[pastel panther]

(jpegs are not that)

[exotic pumice]

https://github.com/sajattack/Adafruit_CircuitPython_ImageLoad/blob/master/adafruit_imageload/gif/__init__.py

if anyone's curious at some point

[gilded cradle]

I meant the bitmaps

[pastel panther]

oh right; yes,that's wise

[gilded cradle]

Nice @exotic pumice . Is it completely working now?

[exotic pumice]

no

it bombs out in the decompression

[gilded cradle]

Hmm, ok. I read a book a while back on programming in C that explained GIF compression pretty well, but it's been so long I only remember it conceptually.

[exotic pumice]

yeah I found a good tutorial

It works on the tutorial image but not on bigger ones

[gilded cradle]

I'm pretty sure it was this book: https://www.amazon.com/Gardens-Imagination-Programming-Maze-Games/dp/187873959X

[exotic pumice]

ok, I followed these docs http://giflib.sourceforge.net/whatsinagif/lzw_image_data.html

[pastel panther]

@meager fog , got 8bpp indexed working. I'll look at those 32bpp next (pyportal build)

[gilded cradle]

I just discarded the alpha channel and 32bit decoded fine

[exotic pumice]

@gilded cradle there's just something subtly wrong with my implementation that I haven't been able to track down

[gilded cradle]

@pastel panther , you can see how I just decoded it like 24bpp here: https://github.com/makermelissa/Adafruit_CircuitPython_RA8875/blob/master/examples/ra8875_bmptest.py

[exotic pumice]

it gets through 12 frames of the gif, idk what they look like, but it crashes on frame 13

[pastel panther]

thanks @gilded cradle

[gilded cradle]

@exotic pumice, I'll have to give it a try and see if another set of eyes might help

Do you have the test gif?

[exotic pumice]

this one works

this one doesn't

[gilded cradle]

Ok, so it's the animated stuff?

Have you created an animated gif before?

[exotic pumice]

I'm not sure

it could be for bigger non-animated gifs too

I have created gifs before

[gilded cradle]

I mean about the crashing

[exotic pumice]

yeah I haven't tested a large, non-animated gif

[gilded cradle]

That crashed too?

[exotic pumice]

haven't

[gilded cradle]

Ah, ok. I'm wondering if some of the gif animation control bits are throwing your code off.

[exotic pumice]

I don't think that's the case

I have animation control bits covered, and it's during decompression that it fails

I'll convert some image to gif and try though

[gilded cradle]

Ok, cool. I was just trying to think why it would get so far and then crash. Do you know how many frames that deploy rainbows one has offhand?

[exotic pumice]

16 I believe

[gilded cradle]

Ok, cool

[exotic pumice]

I just tested a large non-animated gif and it seems to have failed even earlier

[gilded cradle]

Ok, good to know.

[raven canopy]

well that explains why the proper interrupt handler never gets called. TC4 is conspicuously zeroes...

(gdb) print tc_handler 
 $3 = "\000\000\002\000\000"

[gilded cradle]

@exotic pumice , do you have a test script for running your gif reader?

[uneven star]

Is Scott (who I talked to at PyCascades) in this channel?

[gilded cradle]

Not at the moment. He goes by @slender iron

But when he is online, he shows up under Admins

[pastel panther]

welcome @uneven star 😃

[gilded cradle]

Of course you can type something including his name with the @ and it will notify him when he logs on

But welcome none the less

[uneven star]

I tried typing @-scott... and it didn't turn up, and I tried @slender iron earlier and for some weird reason it also didn't auto-complete.

[uneven star]

I played with a circuit playground express at PyCascades and now I'm thinking about how to incorporate one into the talk I'm giving about Mastodon and python-based mastodon bots at PyCon.... toot to mastodon from circuitpython, anyone? 😄

[gilded cradle]

Nice! I'm going to PyCon, so hopefully I'll see you there.

[uneven star]

@gilded cradle raaad. I'm going to see how much circuit python stuff I can get working between now and then... I already made a little binary counter for counting runs through the swag bag stuffing line at PyCon https://twitter.com/phildini/status/1100143861521731584

Philip @ Home (@phildini)

Hey #python fam. Did you know you're all receiving a Circuit Playground from @adafruit at @pycon? If you're going to be stuffing swag bags with us, here's a little #circuitpython script you can use to count (in binary!) the bags you've stuffed: https://t.co/udwa27o16n

Twitter

[gilded cradle]

Oh, great idea. You could maybe even do something with binary and different colors.

[uneven star]

So, that script changes from red to orange at 50, from orange to yellow at 100, and from yellow to green at 200.

[gilded cradle]

Oh yeah, you did do that

[uneven star]

I would love to have it be more gradual, right now it's hard jumps, but maaaathhh....

[gilded cradle]

I like the hard jumps because you can definitely tell where it is

[uneven star]

Yep. Although I need to tweak the shades between orange and yellow. They're pretty subtle right now.

[gilded cradle]

Ah, yeah

[uneven star]

Is there like a blog post I can read where someone has really dug into color math with the neopixel?

[gilded cradle]

Mmm, let me check. I always like to look through the guides at https://learn.adafruit.com/

Actually, I think I got the perfect thing...

[pastel panther]

the fancyled library is pretty great

[gilded cradle]

I did a great palette shifting example for the NeoPixel FeatherWing at: https://github.com/adafruit/Adafruit_CircuitPython_FeatherWing/blob/master/examples/featherwing_neopixel_palette_example.py

[uneven star]

Cool! I'm checking out that and https://learn.adafruit.com/fancyled-library-for-circuitpython

[gilded cradle]

It uses math to get a full rainbow palette

Well, I gotta get going. Have a good night.

D5 - ESP32 RESET
D6 - ESP32 GPIO15

GPIO is not needed

[gilded cradle]

Ok, cool. Just flashed it.

[solar whale]

we need to decide if that should go in the guide - at one point it was decided only to put the argon information in the guide.... if you have an external ESP32 it is best to use ESP32SPI so it may not be useful in general

[gilded cradle]

Yeah, but I'm testing it for the ticket, so it may not be necessary to add it, though we could just in case somebody wants to do it.

Maybe with a warning

[solar whale]

yes -- thank you for testing it! I did it with the feather_m4 so I could test the neopixel status ligt.. argon doesnt use it.

[gilded cradle]

Yeah, that's why I decided on the Metro M4

[solar whale]

should work fine...

[pastel panther]

hey @solar whale Do you know if ESP32s come with a bootloader? Like fresh off the reel ones?

[solar whale]

sorry - I don't know.

I've never had to load one so I assumed it was n ROM like the ESP8266

[pastel panther]

I'm going to assume so

[gilded cradle]

It depends on what you mean by bootloader. It comes with one in the same way an arduino does.

[pastel panther]

By bootloader I mean piece os software that will load on boot and assist with flashing new firmware

what I'm getting at is will it work with esptool out of the box

[gilded cradle]

Yes

I've only used esptool with mine

[pastel panther]

I just found the docs and they agree. Thanks!

@teal thorn What board are you using? Did you change what libraries you're using ? ( or your code)

[teal thorn]

Feather M0 Express. I just updated to 4.0 beta. I am using the bus_device library and my own custom library.

[pastel panther]

What were you using before 4.0 beta? 3.x?

[teal thorn]

I was running the library on another board with 4 beta.

I think my custom lib is near the memory limits of the M0. I probably need to move to M4. Are there any tricks for freeing up memory on the M0?

[pastel panther]

Yea, there are a few things your can turn off in the mpconfigboard.mk for the board in question. Adding CIRCUITPY_I2CSLAVE = 0 can free up some space

there are other things as well that @tulip sleet can suggest

adding CFLAGS_INLINE_LIMIT = 55 is another option

[teal thorn]

That is rebuilding the circuitpython source right? That is not a problem or a surprise, I just want to be sure I understood correctly.

[pastel panther]

yes; in your case you'll need to edit ports/atmel-samd/feather_m0_express/mpconfigboard.mk

@teal thorn there's talk about the same topic going on in #help-with-circuitpython if you want to take a peek

[simple pulsar]

@split ocean I'm messing around in the adafruit_midi module at the moment, if there's any more messages you'd like it to handle, shout now

[raven canopy]

@tulip sleet figured it out last night; was setting things wrong in the constructor with set_timer_handler causing the interrupt handler to never get called. which i assume was causing endless OVF interrupts since the intflag never got cleared. 🤦

@teal thorn If you're running out of memory while running a program, then the rebuild ideas above won't really help: it's that you're just using too much RAM when the program is running..

[split ocean]

@simple pulsar excellent. We just have CC, PitchBend, NoteOn, and NoteOff at the moment, right? Patch Change would be cool. I don't know if I'll make any controllers with Aftertouch or Channel Pressure, but those could be cool if someone did.

[simple pulsar]

I've got an old axiom 25 and I spotted it was sending plenty of aftertouch. I've noted your comments on the ticket i'm working on: https://github.com/adafruit/Adafruit_CircuitPython_MIDI/issues/3

[split ocean]

Nice, thanks. Ooh, I just saw on GitHub that you're working on reading incoming messages as well as building a monosynth. Awesome!

[simple pulsar]

Yep, i've got an external board driven by a CPX with some transistors on which I'm loosely refering to as 2 VCA + mixer for my two osc

where osc are PWMOut

[split ocean]

And the CPX is reading incoming MIDI from your Axiom?

[simple pulsar]

Yep

[split ocean]

So cool.

[simple pulsar]

I got a tiny number of stuck notes earlier, possibly because i'm not treating noteon vel=0 carefully

[split ocean]

Oh, interesting.

[pastel panther]

A panic command would be useful if there isn't one already

[simple pulsar]

A big red button?

[split ocean]

Huge.

Or, accelerometer on CPX so you just shake it like crazy to send MIDI panic message :)

[pastel panther]

😃

oooh, CPX tambourine! and Cowbell!

[simple pulsar]

Are you referring to the all notes off or all sound off from Channel Mode Messages?

[pastel panther]

I'm not sure how it's implemented but many of my synths and/or controllers have a "panic" button that shuts everything up when things go crazy. Both options seem plausible

[split ocean]

I think sending a message on CC 123 with a value of 0 may be the MIDI panic message, but I haven't tried it.

[simple pulsar]

ok, noted, will look into that, thanks

@tulip sleet quick Q: is del foo supposed to call __exit__? just verifying my deinit...

[tough flax]

Hi folks, I'm on the road for the next few days & just want to ask these two Qs before I go - no rush at all, and these aren't requests, just questions 😃 Please tag me if you answer them later...

1) Does the SPI slave software used on the PyPortal offer server programming?  I.e, can I export port 80 and respond to requests (ESPs can do this)
2) I know the ESP32 can also do bluetooth (peripheral and host)... and I'm sure it won't work on the PyPortal out of the box.  However :-)   Would it be possible to use the hardware for that?

[modern wing]

[you're doing the ST:TNG version of it, right?]

[umbral dagger]

@exotic pumice Just CircuitPython 😃

@exotic pumice I do want to build CircuitScheme support for the PyPortal... such an awesome piece of hardware.

@modern wing Indeed

@umbral dagger Indeed? Now I want to build a Stargate SG-1 version.

[gilded cradle]

[raven canopy]

@tulip sleet could be my total misunderstanding of the py/ core, but i can't see where del would call any context management. runtime calls delete functions in objdict, and nothing there suggests __exit__ is called. also tested against a mature module; seems standard behavior i'm observing:

Ran both version on a feather_m4_ express -- the original version reproduces the safe mode crash
the modified version above work normally.

[solar whale]

@tulip sleet so once the shared.py library module creates shared.I2C_BUS = board.I2c() - does it make sence way calling board.I2C() would fail but calling shared.I2C_BUS works

this is why I want to get rid of shared.py !

mornin' @solar whale - noticed the PR for ATControl wifi manager has been merged, want me to open a PR in CircuitPython_IO for supporting it? (I'll add an example/dep for the AT library and do some comments to reference it)

[solar whale]

Sure. Only the examples need to be added. No changes to the library are needed. There are some issues with the ESP8266. Weather example fails. The ESP32 works fine....

[prime flower]

AIO CircuitPython doesn't officially support ESP8266 anyway, not too worried about that.

[solar whale]

As a coprocessor it does not know the difference.

This is where it gets complicated. Only the argon really makes sense for atcontrol , but I don’t think it is officially supported

@prime flower are you testing on an argon?

[prime flower]

I dont have an argon with me, I'll tag you on a PR with a test example (modified data example with the esp atcontrol wifimanager)

[adafruit/circuitpython] New comment on issue #1603: Initializing with board\.I2C\(\) multiple times causing crash into safe mode

No, it shouldn't crash.

[tulip sleet]

@solar whale board.I2C() is supposed to return a singleton, so you should be able to call it as many times as you want. Shouldn't matter if it's assigned to something else or not.

[solar whale]

odd -- clearly makes a difference when done as it is in the featherwing lib. woks fine if just board.I2C() is used everywhere

[tulip sleet]

@raven canopy Are we mixed up: Not sure why del should call __exit__, but __exit_ can call __del__ (but it might not ever do so).
https://docs.python.org/3/reference/datamodel.html?highlight=del#object.__del__
https://stackoverflow.com/questions/40536821/python-enter-exit-vs-init-or-new-del
What was your thinking about del calling __exit__ ?

[umbral dagger]

OK.. touch interaction is good, state machine is good, switching between screens/modes is good. next up is allarm setting mode/screen.

[raven canopy]

@tulip sleet it could very well be me expecting the wrong stuff to happen. Was just testing my deinit...

[tulip sleet]

__exit__ is meant to be called due towith, so I realized that may not be what you need. We call deinit() explicitly because there's no guarantee that del ever does call anything, because a gc might never happen.

[adafruit/circuitpython] New comment on issue #1603: Initializing with board\.I2C\(\) multiple times causing crash into safe mode

I'm trying to reproduce this in the simplest way possible, and not succeeding. Are you saying that your shared.py has:

import board
try:import board
try:
    I2C_BUS = board.I2C()
except AttributeError:
    import busio
    I2C_BUS = busio.I2C(board.SCL, board.SDA)
    I2C_BUS = board.I2C()
except AttributeError:
    import busio
    I2C_BUS = busio.I2C(board.SCL, board.SDA)

And then you get a crash when referencing board.I2C() in other code?
The simple REPL version...

[adafruit/circuitpython] New comment on issue #1603: Initializing with board\.I2C\(\) multiple times causing crash into safe mode

I couldn't get it to happen in the REPL either and I wondered if it might have something to do with calling it in different files or through an import or something. Also, the entire contents of shared.py is basically what @jerryneedell posted above.

[adafruit/circuitpython] New comment on issue #1603: Initializing with board\.I2C\(\) multiple times causing crash into safe mode

I also tried commenting out everything except this in shared and it still crashed.

[adafruit/circuitpython] New comment on issue #1603: Initializing with board\.I2C\(\) multiple times causing crash into safe mode

This might have to do with class and global dictionaries or something like that. I'm not sure it's related to I2C at all, really. If you can give me the simplest test case you can muster that would be really helpful. Thanks.

@timber mango we changed it so we could subclass native classes that take keyword args: see https://github.com/adafruit/circuitpython/pull/1472. Scott discussed it with Damien. Damien liked the idea, but didn't want to change that function signature for backwards compat reasons: he would have added yet another arg or something. But we didn't have that constraint. This is cleaner.

For those playing with a PyPortal (mine comes tomorrow & I'll be in NYC :-/) here's a thought. This service transcodes images on the fly. So, in theory you can take the URLs in <img> tags and URLEncode them and then make the request here with a parameter of &output=bmp -- just a thought

[adafruit/circuitpython] Pull request opened: #1604 Don't wait for display frame if interrupt pending

common_hal_displayio_display_wait_for_frame() would call the background tasks over and over. If a reload was pending, displayio_refresh_displays() would stop refreshing, but common_hal_displayio_display_wait_for_frame() didn't know that.

The effect was that writes to CIRCUITPY would cause the board to apparently freeze (because the display was frozen). It was really cycling in the background task, never to return.

Should be a fix for #1597.

• When PWMOut used a TCC, it did not use the TCC CTRLB LUPD lock mechanism to lock out the double-buffering while writing CCB. This seemed to cause the CCB to CC automatic write on UPDATE not to happen sometimes. The Arduino code does use LUPD, so I copied the way they did it.

I'd suggest not including this Python code in the adafruit/circuitpython repo, but instead in a separate submodule repo as a library like we do the other frozen modules. Then it can be modified experimentally by changing the library repo code and changing `sys.path. If it needs to be updated, it's a very simple PR to just update the submodule commit.

Those errors can only happen when the object is created, and that only happens in the pew.py library that is frozen — the users should never see any of those errors, unless they are creating their own version of the board and compiling their own firmware for it. Because of that, and because I have struggled hard to fit all the required modules inside the firmware, I decided to remove error messages to save space. I will change it to ValueError as suggested, though.

[simple pulsar]

@tulip sleet For that testing I was previously running really close to the memory limits of the CPX and that new uf2 pushed me over the edge. Will I save a lot from mpy'ing the adafruit_midi.py additions I'm working on?

[tulip sleet]

@simple pulsar it can't hurt. In general making an .mpy fixes two things: 1. failure to compile on import due to not enough RAM. 2. Less fragmentation of RAM due to compilation. An .mpy still uses up RAM at run-time unless it's frozen in. If you are just running out of RAM period at run-time due to data and program size, then the .mpy will not ultimately help.

[simple pulsar]

I think it's mainly program size as the approach I'm using is class heavy but I'll have a look any also play with the commands that show the memory footprint

I have a few ideas

[prime flower]

rc-car controller

[gilded cradle]

Maybe

I was thinking more along the lines of making a framework to play games or something, but that might be a little ambitious.

[pastel panther]

hey @prime flower any thoughts/plans about exporting AIO dashboards for use on PyPortal or similar devices? I assume it would need some more supporting code in CP but I think the idea has merit

[prime flower]

@pastel panther as in, mirroring an IO dashboard?

[pastel panther]

Yea. I was thinking there could be some CP side code that knows how to render a subset of the dashboard blocks.

I was thinking "export" because I was imagining AIO could generate assets, if that was needed

[prime flower]

@pastel panther I'd wait until displayio becomes finalized before moving forwards with that idea. Adafruit IO's API supports dashboard and block generation, and you could also GET block information if you wanted to pull the block data and mirror it on a display (https://io.adafruit.com/api/docs/#operation/getBlock).

I think the IO blocks, for instance the gauge block, wouldn't render quickly enough on the PyPortal (as of now) for visualizing real-time data.

[pastel panther]

ya displayio needs to be fleshed out a bit and optimized and even then probably wouldn't be fast enough for some use cases, but even if screen updates were rate limited it could be useful.

For example a temp/humidity histogram that updated every 5-15 seconds could be cool, depending on how fast data was coming in

[prime flower]

a mini histogram for pyportal would be really neat, even if the refresh is a minute

[pastel panther]

heck, you could have AIO render it to BMP at that speed

probably a better way but that would be quick to get going

(sez the guy not working on AIO)

[prime flower]

yeah - a hacky way of doing it would be multiple BMPs for a gauge block to display levels

for example

[pastel panther]

...stored as a sprite map/table thing? 🤔

This is a side effect of the build refactoring I did. The build used compiled nearly everything, or remove stuff in a coarse way. It left -flto to prune out unused stuff. -flto didn't always do the greatest job, so it included unneeded things, and it also hid some places that should have been conditionally compiled.

@tulip sleet Whilst on the topic of PWM and CPX, do you know if there's any way to squeeze an extra PWM out of a CPX, perhaps by disabling something? I put a question on forums about this: https://forums.adafruit.com/viewtopic.php?f=60&t=148017

[tulip sleet]

@simple pulsar The order in which you create the PWM's may make a difference, since only certain TC's or TCC's are on certain pins. Have you tried this? https://learn.adafruit.com/circuitpython-essentials/circuitpython-pwm#wheres-my-pwm-8-21

[simple pulsar]

@tulip sleet No, hadn't seen that but it's similar to my loop. I could write a combination checker if that deinit() does a full cleanp-up. Thanks. I was just wondering if there was someway to sacrifice something like on-board NeoPixels which I presume must use some sort of clock

[tulip sleet]

the on-board peripherals including the neopixels use up a lot of pins which are not exposed on the outside. You could solder jumpers to them. But getting another board with more pins may make more sense. If there are features of the CPX board you're using (like touch) or the accelerometer, then you can duplicate that with offboard stuff.

[simple pulsar]

@tulip sleet ah, of course, I sometimes forget there are other pins not exposed in use. A7 shows up in use even when no code has run, is there someway I can hijack that? ```Adafruit CircuitPython 4.0.0-beta.2-141-g2c9fbb5d4-dirty on 2019-02-28; Adafruit CircuitPlayground Express with samd21g18

[tulip sleet]

A7, aka TX and D1, is PB08. See https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/boards/circuitplayground_express/pins.c and then also see the big table at http://ww1.microchip.com/downloads/en/DeviceDoc/SAMD21-Family-DataSheet-DS40001882D.pdf, starting on page 28, which describes which TC's and TCC's are available for which pins (see columns E and F. That will tell you what the conflicts are. It's "pin sudoku", as Limor says.

The nRF chips are much simpler: most pins can be used for most purposes, but the peripherals are not as capable.

@tulip sleet there's talk of single slope PWM in them and the diagrams suggest this is a sawtooth wave output. Can it really do that? Is there a way to select that from CircuitPython? I don't see a way to select the waveform in https://circuitpython.readthedocs.io/en/latest/shared-bindings/pulseio/PWMOut.html

[umbral dagger]

I'm starting on a PyPortal alarm clock guide . Came out to 525 lines of CircutiPython (plus a bunch of library modules). Almost 140K of ram left after everything is loaded and allocated. This is a sweet, sweet chip/board.

[uneven star]

Does the PyPortal have a speaker? What's the "alarm" portion?

[idle owl]

It does have a speaker, and a speaker connector 😃

[simple pulsar]

Speaker mentioned on https://www.adafruit.com/product/4116 but no power details. I'd assumed it's a 500W affair.

[tulip sleet]

@simple pulsar I think the sawtooth patterns you are seeing are not the output waveforms, but are representations of the TC/TCC counter register values: they increment up and then hit a limit and start over. Any specific page reference?

tiny speaker on the back (same speaker as CPX) and also has audio amp with speaker connector, as @idle owl mentioned

@main meteor Thanks, for my particular use I'd like something hardware driven and I'm already using A0 output on CPX for an analogue out. The M4 stuff is more capable in many ways but I'd like to see what I can get out the humble CPX for now.

[idle owl]

@umbral dagger Hey. You wrote the Prop-Maker Lightsaber code, right?

hmm, I'm not sure if I'm seeing things, but every time I disconnect pewpew with the new cp 4 firmware, it mutes my sound

[idle owl]

@tulip sleet^^

You said something about Spotify earlier...

[stuck elbow]

I need to test it with an official board

[main meteor]

If you're already using the only analogue output, and you want an analogue signal, you'll need some external hardware. I'm thinking a ramp generator (op-amp integrator or constant-current source), or an outboard DAC, but there may be other options.

[tulip sleet]

@timber mango that happened to me too, it turns down the volume on spotify. Something to do with HID Consumer Control, maybe? I don't know what changed to cause this

I thought it was on boot-up, not disconnect, but I was doing a lot of restarting

@idle owl just curious -- have you tried connecting any I2C sensors to your pyportal via the I2C (4 pin JST) connector?

[idle owl]

@simple pulsar Yeah it's in all the guides. It's meant to show how to reset the board. That movement is the same for all boards.

@solar whale I have not, why?

[tulip sleet]

limor said the hallowing was also 5v stemma

[solar whale]

I have a concern about the votlage on one of the pins -- not sure if it is an issue -- I asked about in the #help-with-circuitpython channel earler and @tulip sleet is looking into it. Just wanted to see if you had actually done it .

[idle owl]

I hadn't. But I added a note to the guide based on your question. There's a jumper that you can use to change it to 3.3V. But it defaults to 5.

[simple pulsar]

@idle owl ok, just checking! What's the typical range for power consumption for the PyPortal? I haven't read much about this.

[idle owl]

@simple pulsar No idea! 😃 Others will know better than I.

From the ADT7410 breakout product page.

ah -- thanks.

I guess I'll stop worrying ....

[umbral dagger]

@idle owl Wasn't me. I did the New Years Eve ball drop code.

[idle owl]

Oh hmm. Fair enough, thanks.

Bummer. Was hoping for help with it 😄

[tulip sleet]

@solar whale just checked Hallowing STEMMA connector with a meter. It's also 5V from the factory.

[umbral dagger]

@idle owl I don't know who did it, but I'm happy to have a look and help as I can.

[tulip sleet]

STEMMA is compatible with Grove, which also could be 5V or 3.3V

@main meteor Yep, I thought about external hardware but difficult to know where to stop on that one plus still need some way to control it.

[tulip sleet]

@simple pulsar I have a USB breakout and can measure this in a minute

@umbral dagger I'm trying to adapt it and I'm seriously struggling. I'm about 5 minutes from trying to redo a whole new program myself. Noe and Pedro did another build (an axe) that they want similar functionality for, but not similar enough to simply change a couple of things. I'm trying to make it so it pulses when it's idle. I can't figure out making NeoPixels pulse in a way that isn't blocking. Also trying to make it do a particular thing on swing, which I think might be working, but it's tough to tell with not being able to figure out adapting the rest of the code.

@solar whale No idea.

@umbral dagger long story short, I feel like I'm out of my depth. I thought it would be a simple modification of code to do a couple of other things, but it's turning out to not be simple at all. At least to me.

[pastel panther]

dunno if it actually needs the boost converter

@simple pulsar thanks for the STEMMA link

[idle owl]

@pastel panther You can't power it directly from a battery.

[pastel panther]

Yea but it's got a regulator, right? I'm just sayin' I don't know that it needs to go up to 5v then back down

[idle owl]

Ah

I don't know either then.

[simple pulsar]

@solar whale I came across it and had no idea what it was hence I started looking around for the spec and eventually realised it was an Adafruit thing

[umbral dagger]

@idle owl OK.. Want to move this to a side channel?

[idle owl]

Sure.

[tulip sleet]

@simple pulsar starting up, looks like 150mA, but when the slideshow demo starts running (which varies the backlight), runs like 60-90mA. So the backlight is the big hog.

For some reason with the 4.0 code, even with CIRCUITPYTHON_USB_HID=0 and CIRCUITPYTHON_USB_MIDI=0, disconnecting or hard-resetting the board results in my sound getting muted. I tested that initially with PewPew (which is pretty much a Trinket M0), but confirmed it now with a Hallowing M0 Express.

Yes, more precisely Linux Mint with XFCE4. It doesn't happen on Fedora 28, also with XFCE4.

[pastel panther]

@simple pulsar As has been covered the positive pin of the JST goes to 'VCC' which is a jumper that defaults to the 5V from vbus after the PTC. This means that jumper is basically chosing between upstream and downstream of the regulator

[solar whale]

@prime flower no smoke ?? -- I have one more question about this -- at least -- The ADT7410 data sheet says SCL/SDA absoute rating is VDD+ .3 but they are powered by 3.3V so taht is 3.6V -- is it OK an I2C device is putting 5V on SDA?

[prime flower]

No smoke , no. It's been running logging data to IO for the past hour or so

[tulip sleet]

The I2C device is open collector and doesn't apply voltage directly. It is just open or grounded.

the voltage is provided by the pullups

[solar whale]

so there is 3.3v pullup connected to a 5V pullup correct?

[tulip sleet]

there are 3.3V pullups on the PyPortal. I measured teh SDA and SCL pins on the connector and they are 3.3V

but yeah if you connected an external device there could be 5V on its pullups

[solar whale]

right - and if I connect to an I2C device with VCC = 5V it will use 5V on its pullups

is that OK?

[tulip sleet]

good q, not sure. hold on

[solar whale]

sure -- that is really what has been troubling me.

[tidal kiln]

it would depend on the device - what it does with the actual VCC line

[solar whale]

right -- most seem to imply that the SCL/SDA follow VCC.. The external devices will be OK but I am worried about violating the maximum voltage on the ADT7410 onboard

[tulip sleet]

an example is an SHT31D breakout which doesn't need a regulator cause it's 2.4V-5.5V

[pastel panther]

@solar whale from the ADT7410 datasheet:

Wide operating ranges
Temperature range: −55°C to +150°C
Voltage range: 2.7 V to 5.5 V

[tulip sleet]

then that is OK

[tidal kiln]

but is safe v-logic set by actual VCC used?

[solar whale]

see Table 3 of the data sheet -- absolute ratings -- VDD + .3

VDD can be 2.7 - 5.5 -- but SDA must be < VDD + .3

at least that is how I read it.

@solar whale that's how I read it as well (under absolute maximum ratings?)

Just a note to PyPortal users (as you'd soon discover anyway)... temp readings tend to be higher than ambient due to other bits on the board. Flipping it from slanted on standoffs to upside-down straight vertical drops the temp by 2°F, but still above ambient. Could calibrate that away in a stable environment.

@crimson ferry IMO it's best for monitoring the temp of the board. I.e. insode the case if using one.

thermistor = adafruit_thermistor.Thermistor(

while True:
print((thermistor.temperature,))
# print(((thermistor.temperature * 9 / 5 + 32),)) # Fahrenheit
time.sleep(0.25)
this worked for Celcius

im trying to get it to convert to F

[tulip sleet]

This is working for me:

import board

thermistor = adafruit_thermistor.Thermistor(
    board.TEMPERATURE, 10000, 10000, 25, 3950)

while True:
    #print((thermistor.temperature,))
    print(((thermistor.temperature * 9 / 5 + 32),))  # Fahrenheit
    time.sleep(0.25)

@pallid garnet I just commented the Celsius line and uncommented your Fahrenheit line. I thought perhaps there was a parens problem but it looks fine.

[pallid garnet]

I was able to get this to show me C and F

import time
from adafruit_circuitplayground.express import cpx

while True:
print("Temperature C:", cpx.temperature)
print("Temperature F:", cpx.temperature * 1.8 + 32)
print((cpx.temperature, cpx.temperature * 1.8 + 32))
time.sleep(1)

cpu.temperature may be somewhat less accurate than thermistor.temperature because it's measuring the temperature inside the CPU package (which is slightly warm). But since I got your original code to work, what was the problem you had with it?

[raven canopy]

@stuck elbow got a timer_handler PR in before me, so i got bumped on the #define list. 😦 however, good call on the switch vs if! i've already forgotten switch/case exists (i'm looking at you Python!). 😄

[pallid garnet]

Awesome it's working. Thank You

you can put your code in triple backquotes in discord and it will format it nicely (backquote is to the left of the "1" key)

But I didn't do anything! You did it yourself! Maybe there was just a simple indentation error or something like that.

.......likethat

cool

Would it make any sense to put in an issue to add identical ESP32SPI pin constants from the M4 and PyPortal, to defaults for the ItsyBitsy M4? (ESP_BUSY=D10 ESP_RESET=D5 ESP_CS=D9) I think all of the other Express boards are covered. afaict GPIO0 isn't exposed on the ESP32 Huzzah, but I suppose someone could tie a bare module to a ESP_GPIO0 pin on ItsyBitsy. Just a matter of more consistent examples I think.

[pastel panther]

@crimson ferry I'm not sure I follow. You want to add pin aliases for use with ESP32SPI to the itsybitsy M4?

[crimson ferry]

@pastel panther Right. Minor issue perhaps, but since any Express board can be used with ESP32SPI, wiring instructions and example code can work w/o modification. Right now, I know those pins are defined as above for Feather M4 (though I've scoured and I'm not sure where), so I'm proposing those ESP32SPI pin names get applied consistently across the Express family.

[pastel panther]

Pin names in board files are meant to be labels specific to the features of that board, not general purpose labels for what they can be used for. If someone were to look at the pins for a board and see something like ESP_CS on a board that didn't have an ESP32 attached, it would be confusing.

The feather M4 does not have ESP... pins defined; you might have heard someone suggest which pins to use, or share example code but I just checked ports/atmel-samd/boards/feather_m4_express/pins.c and they're not there

It's expected that sample code will need to be modified to fit the specific requirements of the board or use case that it's being used for.

[adafruit/circuitpython] Pull request opened: #1610 Circuitpython nickzoic 1042 nrf nvm bytearray

An implementation for #1042 for non-volatile memory.

Some example code:

import microcontroller
    
def dump(n = microcontroller.nvm):
    for i in range(0,len(n)):
        print ("%02X " % n[i], end="")
        if i % 16 == 15: print('')
    
microcontroller.nvm[0:4096] = bytes([1,2,3,4,5,6,7,8]) * 512
microcontroller.nvm[107:120] = b"hello, world!"
dump()

PS: I had build errors in lib/tinyusb/src/class/msc/msc_device.c when building master with compiler version gcc-arm-none-eabi-8-2018-q4-major & ended up having to build with -Wno-error=stringop-truncation

OK so I've rebased it and sadly, no change. I've just changed one of the messages for now and provided translations as best I can approximate for the new message.

[solar whale]

@stuck elbow FYI -- I just updated a pewpew v10.2 to the current CP Master build -- seems to be working fine!

[stuck elbow]

@solar whale awesome, thanks for testing!

@solar whale it has more features now, as more modules fit in there

I need to try some example code that turns it into a gamepad

[solar whale]

I have not done much with it yet, but hope to explore. Let me know if you want something tested.

It's nice to have it as part of the CP repository now - thanks for getting it merged

@tulip sleet have you ever actually read images from an SD Card with displayio and the 2.4 inch TFT -- I am finding that somthing clobbers the SD card in the slideshow if I try to use it.. Just curious if you've ever tried it?

I can read the "directory" of images, but then get an I/O error when trying to display.

[tulip sleet]

Limor reported that, and the the PR I submitted was trying to address that indirectly. Are you using the version from my PR (which hasn't been merged yet)?

i'm waiting for her to test it this weekend.

[solar whale]

ah - no -- I missed that -- I'll try it

[tulip sleet]

there are a bunch of parallel PR's, so that includes certain fixes, and others include other fixes. They are all branched from the latest master instead of being stacked.

[solar whale]

is it 1604 for this issue

[tulip sleet]

My fix is not SD-specific: it fixes a bug in the redisplay logic that causes CPy to hang in the background-task loop, never to return to actually executing code. The symptom is that the slideshow hangs. I don't see I/O errors. That may be a different problem or it may be partially due to the problem I'm fixing.
