Yes, the library includes the code to talk to the HT16K33, as well as the wrapper code to use it to control the various different matrices.
So you'd have a line like from adafruit_ht16k33 import matrix and then i2c = busio.I2C(board.SCL, board.SDA) matrix = matrix.Matrix8x8x2(i2c)
storm spoke
Killer, I think this is enough for me to tinker around with. thank you so much! still have many questions but I think I'll fool around for a bit and try to get acclimated to the code. I havn't coded anything at all in 15+ years.

In that case, I think you're better off with CircuitPython than Arduino. They both work, but CircuitPython takes care of a lot of details for you.

madbodger! you still around?
I cant figure out how to light more than a single pixel:
Set a pixel in the origin 0,0 position.
matrix[0, 0] = 1
I've modified the values within the brackets and successfully moved the single led around the matrix, and the value changes the color. but I cant figure out how to illuminate more than a single pixel
gentle bronze
@meager fog good evening there. Yeah the repl should work now
You can also try dfu-flash to test touch1200 as well
Though the arduino uploading still need a bit more work. Since we use the arduino built-in touch 1200, and it is a dance of dtr, rts on/off instead of straight disconnetion (both dtr and rts off ) at 1200. I am pulling arduino ide code to check out what it does to response accordingly.
Sum up, cp all works now, arduino should be ready in your next morning :D
meager fog
wow
ok let me grab my DK
after arduino we hvae some things remaining for circuitpython - like QSPI external flash
gentle bronze
Yeah, right.
I didn't find our flash with local online, I may go to some store to check it out.
meager fog
oh can you make it work with the DK flash
i think it is connected as QSPI?
if not, i can send you a feather
(now that i can test it 😃
gentle bronze
Yeah, I will try to do that first.
meager fog
@tulip sleet was also thinking of splitting up the QSPI management code out from SAMD
so you dont have to do the whole filesystem - just the commands to read/write blocks
since the filesystem part is the same
gentle bronze
Ah, When SD is enabled, it will affect the flashing api flow. E.g erase() won't run blocking and complete. Instead it will only queue the cmd, return immediately, and a separated event (sd soc) signalling the erase is complete in asynchronous way.
It is only technical, but we better to get it ready asap :D
gentle bronze
It has many, but the whole usb has 1 dma for all endpoint
One endpoint transferring, other has to wait
gentle bronze
The problem we run into is, cdc is occuping dma, while the stack try to ack the control transfer
meager fog
.< ok
gentle bronze
They didn't doc that the ack need dma, it is weird since ack in control xfer is zero data length
meager fog
(im compiling now)
gentle bronze
Which has nobneed for dma :D
meager fog
@gentle bronze did you have any corrections for my guide?
i could make it live soon for people who want to test pre-alpha
gentle bronze
Yeah, only the bootloader flahsing part
meager fog
ok bgreat!
it works again hooray 😃
@gentle bronze ok can you tell me what to fix
ill do it now in the guide
gentle bronze
meager fog
or you can edit 😃
gentle bronze
yeah, sure
I update the readme a bit on thathttps://github.com/adafruit/Adafruit_nRF52_Bootloader
gentle bronze
user can just flash the pre-built binary with the VERION=
no, I mean, the VERSION= will just use the hex binary without compiling anything, user should use that, no need to submodule update as well
meager fog
oh ok let me try it
its still good to have whole instructions
also, we should have uf2 generated here right?
gentle bronze
without VERSON=, the make will compile and flash the generated one. Which is only for those who want to develop the bootloader
meager fog
ok ill split into two sections, then
oh one more question, should we update windows gcc to latest in Makefile?
i made this change i could commit it
gentle bronze
yeah sure, I think we should have some find routine to detect it. I will update it
gentle bronze
yeah, not many will interested in compile bootloader. Just key in VERSION and flash the hex 😄
ah, bootloader has dfu-flash as well, to upgrade bootloader using cdc. Maybe needed when the new SD come out and user need to upgrade it
for the uf2 on amazon s3, I have no ideas to push it there !!
but yeah, we should, uf2 is easier for user to flash
meager fog
@gentle bronze ok check out https://learn.adafruit.com/admin/guides/2074/editor/12646
im not sure how to upload the uf2 either, ill open an issue to ask
but now that we hvae uf2 bootloader working well, i think that will be best for quick testing!
gentle bronze
perfect 😄
meager fog
@gentle bronze ok when dan wakes up he can take a look!
meanwhile, if that guide is looking good to you i could make it live
i have a question, you looked into the reset-double-click trick but nrf52840 erases all RAM completely?
meager fog
but RAM is not?
meager fog
says ram may be corrupted but is not erased
we dont need to use registers tho, we use a special RAM location
i think?
gentle bronze
hold on, let me check out the note
gentle bronze
I did it with wiced,
meager fog
yeah
meager fog
kk that is odd, ill think on it
gentle bronze
I give it another try
meager fog
@gentle bronze no need to try now - i was just thinking on it
ok i will put in some issues as i find them now that i can test!
but its late and im going to 💤
gentle bronze
good night
meager fog
thanks - nrf52840 is coming along 😃 now that DK is working i can test feather pins
i had no way to know if they were connected 😄
USB works well now ... its fun
gentle bronze
yeah, usb msc make it so much easier to work with
@meager fog I will try again with double reset, with multiple RAM locations on different banks. Hopefully it will help to address the random behavior, maybe I got bad luck with the last time, hmm. Let's see
gentle bronze
@meager fog the arduino dfu with touch1200 should be working. Though there is IRQ conflict between usb and sd for now, so you should only test with blinky or fading. Or just wait until I get it ready.

@indigo wedge whichever boards have QSPI (or just SPI) flash we'll make CIRCUITPY be the QSPI flash and not have it internal. Then we have a lot more room for the firmware. That's the approach we took with atmel-samd
gentle bronze
@indigo wedge yeah, board with external flash will use that, and those doesn't have one will use internal flash for storage as we are now.
indigo wedge
Cool, sounds good 😃 The next revision of my nrf52840 board will have qspi flash so i was curious how it's gonna work
i was also experimenting with sdcards the other day and was a bit surprised that when i mounted the sdcard it didn't appear in the usb msd, but i should've known better, that would be hard to implement
tulip sleet
@indigo wedge welcome back, btw! Scott is concentrating on graphics right now and nrf52 is my main focus. I am working on pin ownership and cleaning up the pin files, so you'll see even more merge-conflict churn soon.
indigo wedge
ah nice, pin ownership is good, does that include support for multiple SPIs and I2Cs?
tulip sleet
the pin file hierarchy is becoming more like atmel-samd, also getting rid of the .csv file stuff, which I felt didn't add value
indigo wedge
cause right now I hardcoded the instances so we can only have 1
tulip sleet
yes, as many as available
indigo wedge
hmm, but there's still a way to specify a custom name for pins to match pcb silk?
tulip sleet
oh, sure, but instead of generating those files from .csv via the script, you just edit a file that's essentially the output of the script. The csv file is not that readable and has no room for comments. It's sort of too "magic".
I went through all the boards and double-checked and updated the pin names. Also I may add arduino-style pin names (extra names - aliases, e.g. A3, not just Px_xx) on the pca10056, since you can put shields on it. May or may not get to that immediately.
also added the PCA10059 dongle and the PCA10040 (though I don't have one)
if your board design will be public and you want to add it, that's fine
it will save you a lot of constant merging, etc.
indigo wedge
yes i plan to add it eventually, I talked about it with Scott
tulip sleet
feel free to add it now and update as necessary
we have done that with Radomir's boards
indigo wedge
yes, once my board is open source 😃

@slender iron @tulip sleet for boards with a voltage divider wired into an Ain for measuring battery voltage, is the Ain pin named BATTERY?
tulip sleet
@tidal kiln no it's Dsomething. Hold on
split ocean
On HalloWing D9 isn't an ADC, but BATTERY seems to be returning the proper values as I try different batteries.
tidal kiln
yep. hallowing D9 is just brought straight out the header and not attached to anything on the board.
different feathers attach the battery voltage divider to different pins
seems like having a pin named VBATT or BATTERY in board would be helpful
split ocean
these values are same as I'm seeing on my multimeter, so it seems safe to say BATTERY is the one to use on HalloWing
Unless I'm misunderstanding something about this, that is

It's not vital, but helpful for checking level once a project is all put together and parts are tucked away.

@tidal kiln on my machine FEATHERBOOT capacity is 4.1MB, same as OP, but Available is 3.5MB. On the OP's screen shot, Available is 24.8MB (> Capacity!) so the Used calculation is junk, which explains the error mesasge. Maybe just unplug and plug back in. Also, what is version in INFO_UF2.TXT? Could just try cp instead of drag-n-drop. Are they running any 3rd-party disk helpers/utilities, etc.? Any 3rd-party anti-virus?
tidal kiln
@tulip sleet their INFO_UF2.txt has:
UF2 Bootloader v1.18.0 SFHR
Model: Feather M0
Board-ID: SAMD21G18A-Feather-v0
onyx hinge
weird, my m4 express won't USB-enumerate on my laptop but will on my desktop (both debian stretch x86_64), neither in CP nor in the bootloader.
feather m0 express enumerates just fine in both cases
tulip sleet
@onyx hinge is one USB3 and one USB2?
@tidal kiln I tried approximately that bootloader version, but I don't have the build that says "Model: Feather M0", only "Model: Adafruit: Feather M0". It would be good to update the bootloader to the latest and try again. Also, does the user have another Mac in the house that shows the same peculiarity? To update bootloader, could use the appropriate .uf2 from https://github.com/adafruit/uf2-samdx1/releases/latest (way down at the bottom of the list) using another machine, or if that's not possible, try the .ino there and upload using arduino
onyx hinge
@tulip sleet my laptop has USB2 and USB3 ports. On the blue ports (which I think indicates USB3 in this case) there are messages about attempted enumeration that fails. On the black ports, there's not even attempted enumeration in dmesg. On my desktop I'm going through a 2.0-only hub.
tulip sleet
try the hub on the laptop?
this is not usually a problem. I am using USB2 and USB3 ports fine with M4 on a Dell desktop running ubuntu 18.04
maybe check voltages to see if USB voltage is sagging on the laptop
also make sure same cable is being used
try hub both powered and unpowered if possible
onyx hinge
I'll try some of those troubleshooting measures next time I'm trying to use the laptop. I've just shifted over to the desktop for now. Couldn't pass up the chance to complain, though.
tidal kiln
@tulip sleet the one called update-bootloader-feather_m0-v2.0.0-adafruit.5.uf2?
tulip sleet
yes, drag or cp that to FEATHERBOOT
for the .ino, it's an Arduino sketch that can be compiled and uploaded in Arduino, so FEATHERBOOT wouldn't be used
update-bootloader-feather_m0-v2.0.0-adafruit.5.ino
i am not sure this is going to fix the problem - i have never seen this before, but that's a really old bootloader
tidal kiln
i'll try the UF2 then arduino, i'm not sure how comfy the poster is with CLI
tulip sleet
but the UF2 will have to be copied from a different machine, because I think trying to copy any UF2 is going to trigger that message.

yes,that's the easiest thing to vary to test
late flare
hello! I'm having a little trouble with a Trinket M0 project... hoping it will be really simple
it seems like the code couldn't be much simpler (I can post it), just running a color along a neopixel strip... the color is running, but it seems rather slow, compared to other boards I've used... I don't have any sleep statements at all
NUMPIXELS = 23
neopixels = neopixel.NeoPixel(board.D4, NUMPIXELS, brightness=1.0, auto_write=False)
i = 0
while True:
for p in range(NUMPIXELS):
neopixels[p] = (20, 0, 20)
pixel_index = i % NUMPIXELS
neopixels[pixel_index] = (255, 0, 255)
neopixels.show()
i += 1```seems pretty simple, draw the pixels, show them, repeat... but it takes about 1.5 seconds to do the 23 pixels... considering there are no sleep statements, that seems awfully slow, doesn't it?
tidal kiln
@late flare circuitpython will generally be slower than compiled code. see if this speeds it up:
i = 0
while True:
neopixels.fill((20, 0, 20))
neopixels[i % NUMPIXELS] = (255, 0, 255)
neopixels.show()
i += 1
ah, so not iterating over each pixel
oh, I see the flaw now--I could have optimized this even without the .fill
ok, trying now
definitely better... about 3x faster I think
still not as blazing as I've had them going on arduino code... I guess that's expected?

to a certain degree, yes

@gentle bronze @indigo wedge neopixel_write is not yet implemented on nrf. Right now we do sub-microsecond bit-banging (smallest interval is 0.3us) using NOPs for precise timing. We have to turn off interrupts while doing that. If interrupts are off I would think this might screw up the SoftDevice doing BLE. There were some mentions on the NRF forum of delays using NOP's causing such problems. nrfx has delay routines using Systick, but already have taken over systick for timing. Any thoughts you have would be interesting. I am going to sleep but will check back in the morning.

Feel free to comment in either place.

I’m doing scheduling. I’ve put uasyncio back in, enabled a few missing modules (utimeq for example), and modified uasyncio.core to not use utime. It is working (without the stream stuff which I don’t need), but the workaround to get millis is expensive and the scheduler constantly hits it. I’ll poke at those issues and see how well they cover the requirements.

Hello! Does any of you have a code routine to query multiple I2C sensors from an M0 express?
slender iron
@tawny creek np, I can help if needed to. I'm wrapping up spanish now
@velvet oasis what do you mean by query?
velvet oasis
just a PY routine...sorry
I have three sensors connected to the I2C. They all work singularly now I want to read them in a loop
arctic heron
There is no problem reading them so long as they all have unique addresses. Read them exactly like one at a time
slender iron
@tawny creek progress! https://travis-ci.org/adafruit/circuitpython/jobs/422808197#L807
gonna stop travis so it can test es
velvet oasis
@arctic heron do I open the I2C once and assign the I2C to each sensor variable?
tidal kiln
the i2c bus, yes
all our i2c sensor drivers have a default address, so you can use them without needing to specify
but for sensors that have changeable addresses, you can supply it at creation
the changing of address is typically done via some physical mechanism - solder jumpers, wires, etc. and then you match that in the code
velvet oasis
so i2c = busio.I2C(board.SCL, board.SDA) the sensor1 = adafruit_sgp30.Adafruit_SGP30(i2c)
tidal kiln
what are your three sensors?
tidal kiln
in general yes, but you'd want to make sure there's not going to be an address confict
velvet oasis
I did an I2C scan and they appear to have diff addresses
tidal kiln
that's promising! you can also verify by looking at product page or learn guide
for example, for the SGP30:
https://www.adafruit.com/product/3709
down at the bottom, it says:
Uses I2C address 0x58
Ah, I usually am using the lower level operations like writeto(addr, bytes) where you specify the address for ever operation. But yay, even with the higher level libraries, as long as they have different addresses it'll be fine
tidal kiln
but there's also this:
https://learn.adafruit.com/i2c-addresses/the-list
velvet oasis
I did and they all work with single code (code per sensor). Now I want to include them all in one code file
I get I2C addresses found: ['0x1d', '0x58', '0x77']

@slender iron status fwiw:
- got TCA9584A into bundle
- refactored PN532 lib into multiple files to try and help with memory issues, good discussion here:
https://github.com/adafruit/Adafruit_CircuitPython_PN532/issues/3
and the PR:
https://github.com/adafruit/Adafruit_CircuitPython_PN532/pull/6
will let that run it's course before starting to@property-ify the lib and other tweaks - updated the CP section of the LED backpack guide to match changes to HT16K33 library, in the process discovered some minor bugs, opened 3 new issues:
https://github.com/adafruit/Adafruit_CircuitPython_HT16K33/issues
and PR'd a fix for one of them:
https://github.com/adafruit/Adafruit_CircuitPython_HT16K33/pull/23 - still waiting to here from AMS/TAOS on lux equation for TSL2591, got a boiler plate "we'll get back to email"

k let me make the notes doc
tidal kiln
@velvet oasis is the 3rd not hooked up? or why didn't it work with all 3?
velvet oasis
just because I need to write the additional code! 😉

everything else is green tho!
slender iron
yup! so close!
tawny creek
ok gotcha
tawny creek
aight, so I added and committed those files but now they're in conflict.. would it be easier for me to just close the pull request, get a fresh branch place the translation file, make translation and then commit+push+pull ?
slender iron
nah, you don't need to close it. its my fault because I merged the es languagu
let me do the resolve
tawny creek
how should I go a.. ok
slender iron
ok thats not good
you'll need to do a merge locally then another make translate
or I can for you
break time for me. let me know if you want me to do the merge and then check it in

I wrote a module in CP. I call it wakey. It has a method on it that takes a GPIO pin, e.g.: wakey.zzz(board.D12). The code puts the SamD21G18A (I am using an itsy bitsy m0) into standby mode, then wakes up when the pin is sent a HIGH voltage. This works find outside of CP. When I run w/in CP, zzz(board.D12) does not return. I have walked through PulseIn, compared registers...all "looks like it should work" to me. I was hoping there is a chance someone might take a look at the video I made that walks through the code https://youtu.be/S5nP1tgDRCQ to see if you see anything I am doing wrong/missing. The code is located here: https://github.com/BitKnitting/wakey_circuitpython/blob/master/circuitpython/ports/atmel-samd/wakey_helpers.c Thanks very much. @slender iron @tulip sleet

ruby lake
hm, is there a way to import just the button handlers from adafruit_circuitplayground.express
bringing in the whole thing as cpx blows up the code
raven canopy
@ruby lake it doesn't look like you can. the buttons are setup in the Express class, and handled as properties. but, it's easy to just implement it on your own:
import board
import digitalio
button_a = digitalio.DigitalInOut(board.BUTTON_A)
button_a.switch_to_input(pull=digitalio.Pull.DOWN)
button_b = digitalio.DigitalInOut(board.BUTTON_B)
button_b.switch_to_input(pull=digitalio.Pull.DOWN)
if (button_a.value):
#do_a_stuff
if (button_b.value):
#do_b_stuff
yeah I was in the midst of doing that
as I did that for the buttons on the module playground
raven canopy
its not a bad idea to break the items out into classes, so they could be imported at will. but, that adds a little memory to the lib, and may go beyond the intent of the CPX's all-inclusive, easy-to-use learning platform.
might get hard to read too, with all that super.____ going on. 😄
tidal kiln
sounds like something that would be good to add to simpleio
like button boiler plate code
raven canopy
i vaguely remember that being mentioned, with using deshipu's button handling in _stage. but, i lose memory banks as the days go by...
bronze geyser
@raven canopy - Thank you for taking a look the the CP wakey module. I am stuck. @slender iron - if you have a moment...(and i don't see how you could...but i thought i'd ask) do you see anything that would cause not returning from interrupt in the wakey CP module I wrote? I made a short video that walks through the code....https://youtu.be/S5nP1tgDRCQ
tulip sleet
@ruby lake the cpx library is frozen into the CPX build, so if you remove it from lib/ then you'll get the frozen version and it won't use up nearly as much RAM when imported.

@ruby lake you may like the recent raspification of all our circuitpy libraries for your install
you can use various sensors now with raspi - same code

What is the circuit python hardware limitation mentioned in the LED Trampoline tutorial? Evidently, it kept them from running 80 neopixels. I'm using a itsy bitsy and the CircuitPython NeoPixel page says, "You can drive 300 neopixels with brightness control set.. and 1000 LEDs without". I'm using a itsy bitsy and I've noticed that sparkle mode runs much better on my 17 LED strip compared to my 103 LED strip. But, all 103 do light up, they are just slower. And, the test code from the circuit python neopixel page runs just fine. Is the slowness on my 103 due to the power only be connected on one end? (I'm using a 5V 10A power block.)
ruby lake
@meager fog yeah I will check that out over the weekend, have immediate uses
arctic heron
I will point out that it takes 6x longer to send data to 103 then 17. Don’t know if that is the root of the problem
abstract panther
@arctic heron So, maybe its not that it can't drive them. It is that the longer the strip the slower the animations so they decided not to use such long strips. Is there a way to speed up the data ? How do people animate large lengths of neopixels?
arctic heron
According to https://learn.adafruit.com/adafruit-neopixel-uberguide/advanced-coding you can do 328 refreshed/s for 100 pixels which is pretty fast. It could be your software is slowing for 103 pixels, calc wise. It’s a good article
abstract panther
@arctic heron - Thanks for the help. I've read the uber guide. I guess the sparkle code is faster than 328 refreshed/s .
slender iron
@abstract panther The limit in CircuitPython varies because brightness < 1.0 needs a second internal buffer. Its also slower because it needs to compute those pixels.
Then there is the limit @arctic heron talked about which is due to the serial data transmission
abstract panther
@slender iron I have my brightness =.1. Are you telling me if I increase it will be faster?
slender iron
ya, 1.0 will be faster and use less memory. You can still dim the computed colors in the animation
abstract panther
That looks better! Thank you.

@slender iron do you have moment to review this tiny PR in `samd-peripherals? It's a blocker for a big PR in circuitpython. Or I can just merge it. https://github.com/adafruit/samd-peripherals/pull/7

@slender iron @tulip sleet sommersoft added an #include "timer_handler.h" here: https://github.com/adafruit/samd-peripherals/commit/b5effeda2b6b363a27970d19afde097a7e6f77d9, but that file is not in samd-peripherals or circuitpython. do you know where it was supposed to come from? Maye he forgot to git add it. He's offline, unfortunately.
it's breaking the atmel-samd builds for me now
maybe I'll just file an issue for him to notice
slender iron
I don't think its needed
raven canopy
i just got on. 😄
slender iron
the declarations are in timers.h
indigo wedge
@slender iron could you share your 16 bit bmp file, I'm saving mine as 16 bit in gimp but still get NotImplementedError: True color BMP unsupported
raven canopy
timer_handler.h is for moving the shared_timer_handler() back into CircuitPython.
tulip sleet
i advanced to the latest circuitpython, but there's no timer_handler.h in either repo
slender iron
@indigo wedge I used gimp too. Make sure your image is indexed. (Its the image mode)
test files are here too: https://github.com/adafruit/Adafruit_CircuitPython_ImageLoad/tree/master/examples/images

slender iron
@indigo wedge thats the constructor change
in indexed.py change bitmap to take colors as the last argument
indigo wedge
i got past that part now, but nothing is displayed, need to double check my init sequence 😉
slender iron
nice! let me know how it goes. thanks for the feedback!
indigo wedge
there's a small problem, because the samd port and nrf port do pins differently so in nrf board_module_globals_table is inside the build folder in the generated pins.c file, i added the display property there by hand for now but that won't work if i were to commit, but let's worry about that later
Dan is working on rewriting the pin code anyway
slender iron
yup, it should be more similar with dan's work
raven canopy
ok, i need to verify my understanding of something. the prescaler on a TC will have the affect of "speeding up" the counter. example:
TC source GCLK frequency: 48MHz
TC Prescaler: 8
TC Presync: sync on prescaler
so based on that, the number of cycles until counter wrap around: 48MHz / 8 = 6MHz? in other words, the TC's counter will wraparound 8 times for each cycle of the GCLK.
am i off on that?
slender iron
it divides it to make it slower yes. you can change the top to change the period
I was thinking you want to us the 32k clk since you said its better calibrated
raven canopy
ahhh....so it would be 8 source cycles to one counter cycle. i had a feeling i was backwards.
@slender iron 32k is for FREQM's reference, since the reference has to be slower than the target clock. on the M4, i'll be [hopefully] switching to DPLL set to 96MHz (minimum).
tulip sleet
@indigo wedge ...aaand, check out my pull request re pin definitions
slender iron
@raven canopy right, and I'd use it on the m0 too
raven canopy
i'm still just working out having the interrupting timer trigger the read of the external frequency timer. i have a feeling that even doing it this way, i am going to be forced to DMA the external reads. both COUNT and PPW set INTFLAG.MCx. with that flag set, any subsequent captures are not recorded until that flag is cleared by reading CC[x], and INTFLAG.ERR is set.
that especially won't work with COUNT, since you need the last value at minimum to calc the difference.
slender iron
with the freqm? why not just read it when the python code reads it?
raven canopy
😆 that was FrequencyIn related.
raven canopy

you can try use .mpy files in place of .py files to save a little memory
but generally, there is only so much memory and you can only import so many libraries at once
velvet oasis
wow, that's big issue for me....I need to make all these sensors working together...so...is it impossible?
solar whale
@velvet oasis what board are you trying to do this with?
for example, all those libraries will not load on a feather_m0_expresx, but they will load on a feather_m4_express.
arctic heron
Hmm. The more I play with it, the more I think that even if you want to deploy on an M0, you might want to develop on an M4, less fighting memory. Then freeze everything and deploy on the M0.
Know where I can get an M4 itsybitsy or feather in Dallas today?
Hmm, [u]binascii is missing in CP on CPX. Did anyone sneak some version of hexilfy in the CPX as a replacement?
raven canopy
@arctic heron I looked at both Micro Center's and Fry's websites for the Dallas stores. Didn't see any M4s... 😦
arctic heron
Wish I would have figured this out at the beginning of the week, coulda ordered one and got it before I left (tomorrow), small orders to Canada aren't very economical
raven canopy
well, Micro Center had a much larger selection of adafruit items in stock (366 items). their search function is garbage though, so maybe call the store to check?
arctic heron
I suppose I'll just have to order more to make it more economical, right?
Hmm, it is only 17 min drive, I think I'll go visit and browse
I had no idea they sold such a thing
AttributeError: 'str' object has no attribute 'encode'
How does one convert string to bytes in circuitpython?

bytes("foo", "utf8")
cpython got a bit loose on their "there should be only one way to do it" motto, but micropython/circuitpython can't afford the luxury

That works great.
"".join(["%0.2X" % x for x in data]) gets the job done in my case for hexilfy

There seems to be no way in CP to read UART without blocking? i.e. just get me what is buffered. I would expect that timeout=0 would do it, but it doesn't because
while (ticks_ms - start_ticks < self->timeout_ms) {
Most of the time in the first pass ticks_ms == start_ticks so a 0 timeout will actually prevent any reading. If that < was <= it would work.
Is this the intended behaviour or a bug?
(file circuitpython/ports/atmel-samd/common-hal/busio/UART.c)
https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/common-hal/busio/UART.c line 252 for this without the source code handy
arctic heron
pyserial compatibility would be very very lovely, less porting effort!
I currently trying to write a wrapper for UART to make it work something like pyserial, the main thing is to be none blocking , in pyserial of course I just get the number waiting and only read that.
really, though, if .read() returned the bytes waiting when timeout == 0, the API would be non-blocking in that case and be much more usable

@solar whale thanks for the info. how can I solve it? Do I just need to buy an M4? They are out of stock and I still need to check the specs. Is it a full replacement for the M0 but we more memory? Is there a "light" LCD library?
meager fog
@arctic heron thanks for the PR - was nice out so went for a walk - i left a note on the PR
we wanna try and be as Cythony as possible, especially since we are using our UART libraries on raspi with pyserial
@velvet oasis yeah an M4 will have more memory for sure, we'll have more soon, sign up to be notified the moment we get more!
its pretty much pin-compatible other than capacitive touch which we dont have on m4
meager fog
m0 is minimal, we did the best we could with the chips available 😃
velvet oasis
@meager fog Thanks! Any other differences? I do not care about capacitive touch on this project so I assume I can just re-use the same code?
meager fog
as far as circuitpython goes, its nearly identical
some pins can't be sercoms and tere's a few less analog inputs
M0 has like 14 and M4 has 7 i think
but any libraries that run on m0 will run on m4
just much faster

Perfect! What's the ETA for the M4? 😉

we cant promise ETAs but a week or two?
its high on priority list, we're waiting for parts to come in 😃
maybe as early as next week

great. The micro full name is Adafruit Feather M4 Express, correct? I'm not familiar with all your micro cards yet
meager fog
yep

@slender iron heya im hacking on the trellis m4 - have it workin in arduino. i can start the circuitpython variant... do we have a keypad matrix manager ?
cause i can bitbang for now
but hardware support would be ~awesome~
velvet oasis
Does anyone know how to show data always on the same spot without flickering using a RGB LCD?
I want to show CO2 and TVOC. Something like CO2=500
timber mango
Hello! Do the python examples for the circuit playground + crickit work the same on a feather m0 express + crickit?
It might be an obvious question 😐
slender iron
@meager fog gamepad is the closest we have. Ages ago I bitbanged it for my keyboard
meager fog
kuu, yes excpt...we may not have a custom build
tan, ok m4 is fast. will bitbang for now
slender iron
kk
timber mango
Ah thank you :)
velvet oasis
I'm doing something like this... lcd.message('Co2=%d ppm\nTvoc=%d ppb' % (sgp30.co2eq, sgp30.tvoc)) but how do I keep the info always on the same spot?
the LCD tries to scroll
meager fog
maybe clear the screen and set cursor locations?
i havent used lcd on circuitpy yet, guessing 😺
velvet oasis
how do I set the cursor location? lcd.left? that's what you mean?
I was hoping to have something like cursorhome...

@slender iron displayio works great on nRF :) https://youtu.be/eds2tn1L8Is

@indigo wedge awesome! think the api is the right direction?
indigo wedge
Like I said, for my use case right now it doesn't work, I want to be able to draw on the sprites. Also it would be useful to be able to access bitmap dimensions.
raven canopy
@velvet oasis since you're already using the formatting, you could try aligning that way (works for print...not sure about character lcd):
# < == left align; > == right align; ^ == centered
# the number immediately following the align character
# is the 'column' width. (4 is used below)
# you can also specify a fill character; put it before
# the align character: {:0>4} would fill zeroes
lcd.message('Co2={0:>4d} ppm\nTvoc={1:>4d} ppb'.format(sgp30.co2eq, sgp30.tvoc))
I ran an iteration in the REPL:
# x = [1, 2,....100]
>>> for i in x:
... print('{0:>4d}\n{1:<4d}'.format(i, i))
...
0
0
1
1
2
2
3
3
...
98
98
99
99
100
100
and a fill character example:
>>> for i in x:
... print('{0:|>4d}\n{1:|<4d}'.format(i, i))
...
|||0
0|||
|||1
1|||
@raven canopy thanks. The LCD print the first one ok but because of the "while true" then it attaches another one to the first one. Maybe I'm doing this wrong...
raven canopy
@velvet oasis reading back, i think i misunderstood what you were asking. missed the "scrolling" part. are you calling lcd.clear() before each message update?
while True:
lcd.clear() # get a clean slate
lcd.message('now that we're clear \n the newline won't look like a scroll')
Not anymore... #lcd.clear()
lcd.set_color((100, 80, 50))
#lcd.message('Co2=%d ppm\nTvoc=%d ppb' % (sgp30.co2eq, sgp30.tvoc))
lcd.message('Co2={0:>4d} ppm\nTvoc={1:>4d} ppb\n'.format(sgp30.co2eq, sgp30.tvoc))
ok, so I should do a clear
raven canopy
yeah. and you can drop one of those messages.
velvet oasis
the problem with that is it will flicker...
I just tested it and flickers like crazy
raven canopy
then yeah, you'll have to set the cursor before each update. try:
# set initial message
lcd.message('Co2=%d ppm\nTvoc=%d ppb' % (sgp30.co2eq, sgp30.tvoc))
while True:
# update Co2
lcd.set_cursor(3, 1)
lcd.message(sgp30.co2eq)
# update TVOC
lcd.set_cursor(4, 2)
lcd.message(sgp30.tvoc)
you may have to adjust the column and lines to your particular setup...
velvet oasis
testing... 😉
I get TypeError: 'int' object is not iterable
it doesn't like this line lcd.message(sgp30.co2eq)
raven canopy
i didn't put the formatting in the example.
lcd.message('%d ppm' % sgp30.co2eq)
sorry. 😉
velvet oasis
my bad man, novice mistakes. Thanks for the help. re-testing!
I assume the first number is the horizontal and the second is the row...
raven canopy
yep. def set_cursor(col, row)
velvet oasis
It works! The only change is the first row is actually 0 (zero) and row 2 is 1!
raven canopy

So I see that import upip doesn't work in my repl - what's the recommended way of getting pip modules onto a CircuitPython board? Running the NRF52 feather if it matters at all.
Short of just writing a makefile step that pulls the modules locally and copies them over with ampy, I suppose
timber mango
Are there any ways to wirelessly control something using a Feather M0 Express?
sudden coral
Second question, is it normal to only have about 4kb free on my Feather NRF52 with CircuitPython installed? I can work with it, but yowsers that seems tight on such a big board
timber mango
What's the recommended way of including a license on a M0 board? Just insert it into the main.py file? Separate text file?
meager fog
either!
solar whale
@sudden coral how are you determining that ? on mine I see ```>>>
import storage
dir(storage)
['name', 'VfsFat', 'erase_filesystem', 'getmount', 'mount', 'remount', 'umount']
import os
os.statvfs('/')
(4096, 4096, 20, 11, 11, 0, 0, 0, 0, 255)
I rebooted my device and suddenly had my 20x4096 back
Must have been a leak somewhere or outdated information from after I removed a file with ampy
solar whale
@sudden coral as to using upip -- I don't think it is available What are you trying to install.
sudden coral
At the time I was trying to use the enum34 backport, then quickly decided I wasn't eating the 31kb filesize and converted those usages to plain old
class DiodeDirections:
COLUMNS = 0
ROW = 1
This is what I get for not mentally switching to minimalist mode when working on a keyboard, and instead sticking to work mentality where disk space on our servers is cheap and we can import whatever...
solar whale
It is a different mindset -- sounds like you are getting things working -- Good luck!
sudden coral
Yep: https://gist.github.com/klardotsh/98bae8ac1f50d454e1699904f870a9c5
I can parse a 2x2 keyboard matrix into keycodes (well, not keycodes yet since I'm not sending over HID yet)
Thanks for the pointers!
solar whale
Nice! Thanks for the example!
sudden coral
Yep! This is kind of the early beginning stages of a keyboard firmware a friend and I are building out inspired by QMK. Writing keyboards in Python is a whole lot nicer than writing in C 😃
solar whale
Sounds like a great project - I hope you'll keep us posted on your progress!
sudden coral
If I want to freeze my code into the zip file flashed with make dfu-gen dfu-flash' what's the recommended way to do it? I tried adding FROZEN_DIR=freeze to my make args, which partially worked -in the repl, I can import main and see my file, but it doesn't auto-run on boot
Basically I'm looking to cut ampy out of the deploy pipeline (at least in "production" builds) where I can have a guaranteed "run flash and this Feather is now a KMK-running keyboard, done" flow
solar whale
sudden coral
Is there a way to have said main.py show up as part of the DFU flash?
^ that flow is how my friend (developing for MicroPython stock on a Teensy) has to get main.py on there, and making the builds consistent (minus the language differences, I guess) would be awesome
(logic would say "then why don't make the whole project in MicroPython?", but after flashing MP stock to my Feather, I just bootloop, even using AdaFruit's dfu flashing scripts from the CircuitPython Makefile, so I've stuck with CircuitPython for the Feather)
solar whale
I’ll defer to others. With the holiday weekend, not sure who is available.
sudden coral
No worries! I'm not really in a rush, most of this is just "nice to have some time" level stuff
solar whale

Sorry for the barrage of questions today, I'm now running into a problem using the adafruit_hid wrapper. Looks like it doesn't exist by default in my CircuitPython install, so I'm trying to push it onto the device the harder way with ampy. This crashes and burns:

Not a whole lot I can go off of in that trace unfortunately -is there a way I can see more verbose output?
allegedly it was able to push one of the files, and that's it. keycode.py made it onto the device
meager fog
klar, its a lot easier to put files using mass storage, what board are you using?
sudden coral
Feather NRF52
bulit CircuitPython with make clean BOARD=feather_nrf52832 SERIAL=/dev/ttyUSB0 dfu-flash, so I'm assuming I should have defaults. I see a git submodule for the Adafruit HID lib, but it never ends up on the board
sudden coral
oh? 😬
meager fog
yah i dont know anyone who'se used it it, maybe arturo?
and you'll never have HID, its not native USB
which is why haven't super-supported it, we're aiming for nrf52840 instead
sudden coral
aaaahhhh. Yeah, this board has been... fun in a million ways. Actually only found CircuitPython after failing to get MicroPython to boot on the thing for hours on end Friday night 😃
sudden coral
Yep - I have a keyswitch matrix working
meager fog
but yeah for HID you need something with native USB, like SAMD21 or SAMD51
those work supergood
or you can wait a fe wmonths 😃
sudden coral
I see various code and tickets in the repo for BTLE HID - is that supported on this device, or is that also punted to the nrf52840?
meager fog
there might be the first inklings of having the ble side act as HID
but its probably not working
i know we haven't done much of the wireless side
arduino has it for sure tho
sudden coral
Gotcha - I've seen example BLE keyboards on the Arduino side of things (someone in /r/mechanicalkeyboards did some fun wizardry in that regard). What I saw in the repo for these chips looked promising, but makes sense that most of that support is for the upgraded version 😃
sudden coral
Does flashing CircuitPython to a board not wipe main.py? I managed to infinite loop with no yields in my code (oops...) and now can't rip the file off the thing
Is this now a brick unless I buy a Jlink?
Solved. Flashed a build of CircuitPython that didn't have my dependencies frozen into it, which forced an ImportError and crash
solar whale
@sudden coral It does not wipe main.py and Control_c is crrently broken on the feather52832...
sudden coral
sudden coral
I think I was very lucky with how I discovered this... bug? I guess I'll call it? in that I was depending on a module I had frozen with FROZEN_MPY_DIR and thus had a way out through several DFU flashes. I'm.... pretty sure I'd have a brick had I tried copying main.py even an hour prior. Phew! Noted though, I'll have to pick one up
solar whale
Another way is to edit the startup code to force it to create a. new file system.
IIRCC Making thiis excute will force creation of a new filesystem https://github.com/adafruit/circuitpython/blob/master/ports/nrf/supervisor/filesystem.c#L48
replace The if clause with True
Or I mean force it to execute.

Hey everybody - is there a way that I can see the "interpreter version" of the error that's flashing on my itsy bitsy m0? I copy/pasted code from another itsybitsy M0, so I'd like to see a bit more detail beyond the RGB error display...
solar whale
@opaque thicket If you open a terminal session to your board then send a Control-C - it should allow you to enter the REPL -- then enter Control-D to "soft reboot" and your errors should display on the terminal session.
tulip sleet
@indigo wedge Do you have further comments on https://github.com/adafruit/circuitpython/pull/1158? @slender iron if this is OK enough with you, could we merge as it stands and then I will rework DigitalInOut to use the open-drain output capabilities of GPIO, and turn on strong pin driving.
indigo wedge
Ok, let me have one last look
tulip sleet
@indigo wedge also I will open issues to allow multiple instances for I2C and SPI. Right now only one instance is provided, assuming I'm reading the code correctly. Are there other periphs that provide only one instance but could provide more?
indigo wedge
I2C and SPI share same HW module for SPI1/I2C1 and SPI2/I2C2 and on nRF52840 there is also a unique SPI3 block, in the drivers the the i2c and spi instances are hardcoded so you can't use 2 SPIs at the same time for example
i think spi should prioritize SPI3 as first one because that's the only one that can do 32MHz
don't think any other modules share hw blocks
nrf52832 has 1 UART and nrf52840 has 2 uarts
but those are their own thing
ah and QSPI is a separate block too
so taht one i guess we can only use for exrternal flash
also we should have a issue for rewriting pwm in nrfx, it's a bit messy right now
tulip sleet
Got it, I see the identical base addresses in 4.2.4 in the datasheet. so it's sort of like atmel SERCOMx except no UART. It would be nice if it were described as SPITWI1, etc. :/
we could choose SPI based on specified freq in the constructor
so you don't have to instantiate the high-speed one first to get it
indigo wedge
but the constructor doesn't take a speed parameter, it's in configure
tulip sleet
oh blah, maybe it should, since having to know the order is going to cause support problems
indigo wedge
yeah, alternatively we could default to SPI1 and switch to 3 if the user calls configure with higher speed than supported by SPI1
since we don't use DMA then we know no operation is ongoing, so should be safe
tulip sleet
yes, we could switch under the covers, since there's a full crossbar for the pins.
indigo wedge
yes, nrf is nice like that 😄
tulip sleet
i thought all periphs use easydma all the time
indigo wedge
yes they do but we use blocking operations
tulip sleet
eventually ... we may not do that. this is worth discussing. unfortuately i can't attend today's audio mtg
indigo wedge
yes, but i think the dynamic switching is fine for now, we can rethink it later when we go for DMA
tulip sleet
anyway I will open issues for to-do's and discussion
indigo wedge
but then we need a good async api
tulip sleet
that is the $64k api
indigo wedge
sounds good, you can quote me in the issues 😉
tulip sleet

Recently worked on a collaborative project with @split ocean to design a hybrid PCB (analog and digital) and code to read a Eurorack synth control voltage (CV) signal and display it on a 1930s-40s vintage analog RF meter in a very retro-cool case. The signal is processed by a Trinket M0 running CircuitPython that protects the meter by controlling range and skew. The Trinket’s DAC output drives the retro analog meter.
Working on a film miniature lighting animation controller for a local film group. The project involves an ItsyBitsy M4 Express with CircuitPython, a bunch of NeoPixels, and a panel full of knobs and switches.
I'm writing a learning guide about front panels. Stay tuned.

FrequencyIn: 2nd "control" timer added, and working. Using DPLL1 @ 98 MHz as the timer source is working on M4. Still a fair amount of jitter on the higher-end readings that I need to work out; not sure if it's clock or timer related. Using XOSC32K; going to test with OSCULP32K tonight. Up next is DMAing the capture timer, to overcome the loss of capture interrupt. 😵

Since now using a second timer to "schedule" the value updates, the capture timer(s) doesn't set the interrupt on capture. However, all captures still set the INTFLAG, which causes the capture to not be recorded in to CC[n].
