Seriously. So many. We were trying to get it into the CPX lib and it was days and days of work to figure out making it work.

raven canopy
#

yeah...that seems unnecessary to require the interrupt. but, i do remember the troubles you all had with it.

tidal kiln
#

but there's also the IA bit in CLICK_SRC

#

i'd think both would happen - the IA bit would get set and the INT1 output would get set

#

up to you which one you want to tie into

raven canopy
#

gotta run. have a good night everyone! ๐Ÿ‘‹

idle owl
#

Night @raven canopy !

#

So... I guess update the example to use the interrupt pin for now

tidal kiln
#

yah. dunno. not seeing why that's needed.

idle owl
#

my thought is it works this way, it doesn't work the other way... I realise that's not fixing the issue, it's a workaround

#

But I'm not ready to head back down that crazy path at the moment.

tidal kiln
#

๐Ÿ‘

#

in other news... my logger is still kenny logging

idle owl
#

I forgot mine in the freezer, so I took it out and put it in a bag after I held the bag over hot water, and then closed up the bag and set it in the bowl of hot water so it's all humid in there.

#

leave it there for a bit, get it out, let it log on my desk for a bit and then tah dah I should have a fun graph.

#

Travis hasn't passed yet.

#

It may not, I haven't setup a test environment yet, so I didn't test it locally.

tidal kiln
#

was this pr prompted by that issue (#28)?

idle owl
#

um an issue, don't remember the number

#

so probably

tidal kiln
#

most likely. the title is "tap.py example not working"

idle owl
#

Yep that's it

tidal kiln
#

i still can't figure out why that's required

idle owl
#

ยฏ_(ใƒ„)_/ยฏ

tidal kiln
#

but i can't recreate that

slender iron
#

@tidal kiln the IA bit gets clear once you read it. the interrupt line doesn't

tidal kiln
#

yep. but where's the true coming from? it's the IA bit, right?

slender iron
#

yeah I think so

tidal kiln
#

and not from reading the digital input tied to int1

slender iron
#

I don't have enough context to say

#

I was just trying to clarify the difference between the bit and the pin

tidal kiln
#

gotcha. yep. knew that.

slender iron
#

kk

tidal kiln
#

just not seeing why the code only works when int1 is defined

#

since it's using the IA bit

slender iron
#

are you thinking they should work the same way?

tidal kiln
#

i guess i see it as two ways

#

you can tie into the int1 (or int2) line if you want, and then monitor that

#

or check the status of the IA bit

#

some trade offs between the two approaches, but both should work

slender iron
#

there was some trickiness to having IA reset after a given amount of time versus on read

tidal kiln
#

i'm reading it in a tight loop

#

after, i think, configuring everything else same as driver does

idle owl
#

@tidal kiln Did you approve the PR or are you still trying to figure out the why

tidal kiln
#

the later ๐Ÿ˜ฆ

idle owl
#

ah. ok

tidal kiln
#

the "does not work" one never exits the loop

slender iron
#

you are doing double tap right?

tidal kiln
#

yep

#

the commented out one works

slender iron
#

it might use IA to determine if one tap has occurred

#

and by reading it you clear it before the second tap is detected

tidal kiln
#

so...might work for single....

slender iron
#

right

tidal kiln
#

and it does

#

so int1 is somehow being used for the double tap logic

slender iron
#

its readign click_src not int1

#

but yes, we want latching of click so that we don't miss clicks but that means we need to read something besides click_src

tidal kiln
slender iron
#

actually! what if it read int1_src?

#

instead of click_src

tidal kiln
#

interesting. see that. there's not much discussion about the difference between the two.

slender iron
#

actually, I don't think that will work

#

there is a difference between interrupt generators (int1, int2 and click) and the pin itself

#

ctrl_reg3 determines that mux

tidal kiln
#

i see what you're saying. you can only setup the pin for one source.

#

but the IA in INT1_SRC will trigger for any of them

#

"one or more has been generated"

#

@idle owl running out of time. merged for now. left comment for future reference.

idle owl
#

Ok. Thank you.

tidal kiln
#

wow. there's been some discussion around this.

[adafruit/circuitpython] Pull request opened: #785 RFC: atmel\-samd/samd21: Rework clock setup \+ calibration

I want to be able to calibrate the OCS32K clock on the Circuit Playgorund Express in order to improve the RTC accuracy.
The factory set calibration value is 0x37 which gives me -8000ppm, changing to 0x36 gives -2000ppm.

As part of trying to understand the convoluted asf4 clock setup, I reworked it to be simple and explicit, encouraged by the comments in #777.

The reason I first have a patch that enables OSC32K the asf4 macro way, is so the rework patch doesn't introduce any functional ...

[adafruit/circuitpython] New comment on issue #516: Feather Express M0 \- pulseio\.PulseIN \- freezes at high frequency

Now that PulseIn is in 3.0 (with updated tick_delay to boot), I decided to give this a run. I don't have a sensor available that will pulse >25kHz, so I used a Feather M0 Express with PWMOut.

Feather M0 Express was running this PWMOut script. 50% duty cycle, starting at 8kHz with incremental increases.

ItsyBitsy M0 Express (w/JLink) was running [this PulseIn script](https://gist.github.com/sommersoft/3b7a8fd6f8...

sommersoft
[adafruit/circuitpython] New comment on issue #516: Feather Express M0 \- pulseio\.PulseIN \- freezes at high frequency

I'm still narrowing down where to look specifically, but something interesting is showing up. I've had the Feather PWMOut script halted, and the jumper removed, for over 20 minutes. When I pause the ItsyBitsy and step-over in Atmel Studio, the callstack shows that it's cycling through instances of EIC_Handler. The REPL is also still unresponsive.

CORRECTION: I thought I had the jumper removed. After actually removing it, the calls to EIC_Handler subsided. REPL became responsive....

#

soo how easy is it to expose a pin that was previously 'unexposed' ?? -- am I right in assuming that pins.h file is the file-to edit, or are there other places I should look at.

@idle owl @tidal kiln I have been reviewing the AM2320 and DHT data sheets lately and came across an interesting item. In the AM2320 document: Soldering Information Manual welding, at a temperature of 300 ยฐC maximum contact time must be less than 10 seconds. I wonder is this is part of the problem Kattni is having. If this "welding" temperature refers to the soldering temperature, then it can easily be being exceeded. I have not soldered my sensors to any boards. i use them in breaboard sockets. Since I use lead-free solder at 400 C - I would imagine I'd violate this for sure. Even with leaded solder, typically the temperature is over 300 C. This is one difference between Kattni's boards and ther rest of us who have been testing it. HAs anyone else soldered one of these to a board? I assume that the time is more critical than the temperature but I'm curious what you think?

modern grove
#

@solar whale I was planning to solder a am2320 tomorrow..

#

I've been soldering since I was twelve though, I'll be making contact for less than a second.

solar whale
#

@modern grove I would not expect it to be a problem, but I was surprised by the note. What temp do you set your iron to?

#

or if not temp controlled, just curious if you work with leaded or lead-free solder.

modern grove
#

Leaded, just well ventilated, my mother drilled that ventilation thing into me when I was a kid.

#

and I use a cheap iron, sometimes even a butane one if it's just a quick in place job.

#

In 30 years of playing with electronics, I've never owned a proper soldering iron!!

solar whale
#

@modern grove I just recently treated myself to a temp controlled iron and have switched to lead-free just to see how it goes. My first experience with it a few years ago was a mess, but I seemed to have gotten used to it now ๐Ÿ˜‰ I suspect this is not a real problem for the am2320 if you are minimizing the heating time and especially at the lower temps for leaded solder. I only raised it because of some recent troubleshooting/headscratching we have been doing.

modern grove
#

I'll let you know how I go. It makes sense to add one to my current project..

solar whale
#

Good luck - I have had no problems with mine. BTW - i do not mean to sound like an advocated for lead-free solder - I am not -- Especially for beginners - leaded is so much easier and good ventilation is necessary for both!

modern grove
#

It's off topic though.. but an mqtt console.. which already has a ds18b20 submersible on it for the fish tank..

solar whale
#

Very nice!

modern grove
#

The bedroom temp humidity comes from a Xiaomi ZigBee device in the bedroom.. home assistant publishes all state changes on all smart home devices to mqtt.

#

It's really off topic. It's written in C++ but uses the adafruit ili9341 library.

#

If you are willing, I'm sure folks would like to see the details on #show-and-tell - I know I would!

modern grove
#

Yeah I will definitely do that. Still got a bit to code on my library.. the work in progress is up on my GitHub as I go. Need to implement swipe for multiple pages... And dialogue box with some basic widgets like brightness and a colour wheel.

#

It's designed to sit on my kitchen bench and replace an old school non connected 433mhz dumb weather station my girlfriend refuses to let go of because it's more convenient than opening home assistant and looking at the temperature

#

And then scope creep led to touch screen for the rest of the smart house

[adafruit/circuitpython] New comment on pull request #780: Fix GPIO16 Board Reset; Updated Usage

I also tested at 3.0.0-alpha.6-5-g396e4ffc3 and "GPIO16" now works for me as an input. Thanks @sommersoft !

Besides testing as an input, I also tested this:

>>> a = digitalio.DigitalInOut(board.GPIO16)
>>> b = digitalio.DigitalInOut(board.GPIO16)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: Pin XPD_DCDC in use```

This is clearly what the code intends but I have to admit that I'm not sure *why*.

@tawny creek the pins are all the same based on the MCU and defined here: https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/samd51_pins.c The only thing that varies per board is the friendly names defined here for example: https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/boards/metro_m4_express/pins.c Pins are always available by their MCU name in microcontroller.pin

[adafruit/circuitpython] New comment on pull request #785: RFC: atmel\-samd/samd21: Rework clock setup \+ calibration

Overall, this is amazing!

I don't think it belongs in microcontroller because whats in there should be microcontroller family agnostic (I realize pins naming changes a bit between MCUs.) However, this would be awesome to have in a samd module specific to the family. We had this in 2.x but made its functionality generic in 3.x. So, here is how it was implemented: https://github.com/adafruit/circuitpython/tree/2.x/atmel-samd/bindings/samd

[adafruit/circuitpython] New comment on issue #516: Feather Express M0 \- pulseio\.PulseIN \- freezes at high frequency

That's pretty much the conclusion I've come to today. I removed the pulsein.clear() from the script, thinking that the interrupt disabling was a culprit. That got me up to 64kHz before locking up.

Setting a breakpoint in Atmel Studio on pulsein_interrupt_handler proved interesting. With continuous output of total_diff, last_ms, and last_us, it shut down the serial comms to the terminal, but kept chugging right along past 128kHz. The only problem: total_diff never gets below 18...

the bitbangio has a copy of code and doesn't use extmod/i2c.c

#

well, the fix is that it doesn't use a hardcoded timeout anymore

it's over 250ยตs

#

or to use code from extmod/i2c.h/.c instead of a copy

we will miss further fixes if we keep using a copy

They gave me the best price on BOM among the fabs I tried (probably because they actually searched for the best sources), they helped me with a few design problems (but only after I pointed out there is something wrong), and they are reasonably fast (though you have to be aware of Chinese holidays).

Meant CxO - not sure what role @ndavenport has

Guessing it's a one-person hobby project, but not sure. Still, their 'getting started' resources might be a useful reference

solar whale

looks interesting. I was using AIO as an example just because it comes up often in discussions on the Forums and discord. It would be great to have additional examples to show.

hollow ingot
#

With the Huzzah as one of their two primary targets, it might be worth writing it up as a 'review' of a third party IOT service for interest, but not sure if that's the kind of content which Adafruit might host. It's orthogonal rather than competitive to AIO given the focus on management and remote code development rather than logging. Perhaps an AIO service can be deployed using Pozetron, proving how both development and logging target a remote device.

@hollow ingot thanks - It's still nice to read up on it and play with it. I may not include in this guide but it may be a useful thing to be able to point people to. Or possibly a section with "other useful links"..

Ok for the Gemma project, if we want rainbows, and we ALL want rainbows on everything, it's going to end up looking a lot like the Ikea lamp hacking code, which is handy because I already wrote that code. So I'm going to adapt it to this and change up what the modes are: rainbow, Python Colors back and forth probably, and something else.

slender iron
#

I bet that'll impress regular python folks

idle owl
#

Context: I'm writing up a quick guide for PyCon using the Gemma, with a piece of code you can put on it to do some fun things with the onboard LED. Then you can attach it to your swag bag or your badge and tah-dah, light up bag or badge. Or whatever you attach it to.

#

Yeah! Should be good

tidal kiln
#

@idle owl and using only what's on the gemma?

idle owl
#

Capacitive touch will be the inputs.

#

So it'll have a set speed for the cycle and brightness, so no state machine included to try to expand the 3 touch inputs beyond being 3 inputs.

#

Although if I follow the code, I won't need state machines to include changing speed and brightness. Realising that the Ikea lamp code only had 3 inputs in the end. The fourth one was shake to turn it off, and there's a switch on Gemma for that.

tidal kiln
#

the gemma switch is a power switch though, not like the cpx slide switch

idle owl
#

So I can have one pad cycle through modes, one pad cycle through a few brightness levels, one pad cycle through a few speeds.

#

Right

#

That's good. Means you can turn it off instead of the fake off I had for the lamp, which just turned the LEDs off.

tidal kiln
#

ah gotcha.

idle owl
#

Hah! Needed state machines after all. So that you don't skip through a bunch of modes each time you touch it.

fresh knoll
#

@idle owl you should add a 'p' to the end of your user name :)

tidal kiln
#

@idle owl maybe you could get away with just adding some time.sleep() to debounce the touch?

idle owl

that messes with the rest of the code. It's all done with time.monotonic()

It's already done ๐Ÿ˜ƒ

Hello everyone please let me know when I can butt in.

tulip sleet
#

we've had erratic behavior with the AM2320 even with regular I2C. It can fail randomly, though not as often as yours. jerryn discovered that if you power it up with SCL grounded, it acts like a DHT22 and uses that device's protocol.

#

so you could try the DHT22 driver if you wish

ah let me try that

@humble mural did you try running as administrator?

tulip sleet

The CIRCUITPY filesystem on your board has become corrupted.

You need to erase and reformat it. What kind of board is it.

let me try it again

@tulip sleet and @raven canopy I just refreshed the CPX I am going to run Mu as admin. I'll keep you posted.

tulip sleet

you should not need to run as admin. sommersoft was just suggesting that to solve a different problem which you don't have

better not to

you mean it was left over?

"Could not save file" "Error saving file to disk. Ensure you have permission to write file sufficient disk space"

tulip sleet

do you have a CIRCUITPY drive in an Explorer window?

quit and restart mu if you have not done that yet

humble mural
#

Dan, I close a Windows explorer window the was displaying CIRCUITPY and I restarted Mu. I restarted Mu and I still get the error.

#

Dan should I uninstall/reinstall?

raven canopy
#

@humble mural what Dan is saying, is that the filesystem on your CPX is corrupt.

#

you'll need to erase it. The link above he posted will help you with it.

humble mural
#

I wiped it and reinstalled it, double click on the reset, it went back to something else (i forgot) and then i dropped in the CPX .uf2 file and made a a CIRCUITPY agaain

raven canopy
#

that only installs the firmware. it doesn't touch the file system area.

humble mural
#

adafruit-circuitpython-circuitplayground_express-2.2.3.uf2 is the file correct??

ohhhhhhhh

let me go back and read that link that Dan gave me

@tulip sleet and @raven canopy thanks that did the trick. the CPX and the Mu editor work wel now. I think there is something in the code that needs to be worked out. Otherwise, it done.

raven canopy

@humble mural yay! glad you're back in business.

2.2.4 is the latest

actually 2.2.3 is fine 2.2.4 is only a fix for DotStar brightness on a few boards. Not an issue on CPX.

@tulip sleet Awesome, we downloaded that on Friday, based on the date (March 7) we have the newest veriosn.Thanks again.

tulip sleet
#

glad you got it working again. 3.0 includes a much easier way to reformat the fileystem: you can do it from the REPL.

#

on Windows, make sure you Eject before pulling the plug on the board or pressing the Reset button. That will help prevent filesystem issues. The Mu editor is good about writing the whole file out at once; some editors are not.

humble mural
#

I'm very good at doing that but my students may not. Many still think that this an Arduino board that you can just close the IDE and pull out the USB cable.

@warped pendant are the LED's on during that 120 hours? battery life would be highly dependent on how much the led's are being illuminated. a full-on Neopixel with RGB all set to max brightness is 20ma per color , 3*20=60ma.

@solar whale can you link to the AM2320 data sheet you were reading? i could google it, but want to make sure i use the same one. i'm now getting lock ups and when it happens SCL is "stuck" low, so it might have something to do with that non-i2c mode

Hi, When I plugin my Metro M4 to Ubuntu the device is in read-only mode so I can't save any code files. How can I fix this? chmod didn't work

raven canopy
#

@tidal kiln the one at the bottom of the product page has the info, IIRC.

tidal kiln
#

@brazen cedar through GUI, command line, or both?

brazen cedar
#

tried both

#

also my Neopixel is solid white and the TX LED is lit

tidal kiln
brazen cedar
#

I just did that

#

I tried looking up what the neopixel color means but didn't get any hits

tidal kiln
#

does the CIRCUITPY drive at least show up?

#

can also check /media/username/CIRCUITPY

brazen cedar
#

yes it does and I can open files just cant write to it

#

/media/username/CIRCUITPY is there

tidal kiln
#

but same deal, read only?

brazen cedar
#

yep read only

tidal kiln
#

try just pressing reset, let it remount, and see if it changes

#

and try a couple of times

solar whale
tidal kiln
#

i'm on ubuntu as well and have this issue from time to time, with any CP board

#

@solar whale thanks. also thanks @raven canopy i looked, but missed that little linky down there ๐Ÿ˜ƒ

raven canopy
#

Yeah. The learn guide linked higher up is missing the datasheet..

brazen cedar
#

@tidal kiln I reset the board several times and the error persists

solar whale
#

for CIRCUITPY on Ubuntu I often find that I have to manually mount the drive byt clicking on the icon in the file manager, but then I cant't drag/drop to it. I can write to it via the command line just fine but no drag/drop. Sometimes restarting the filemanger helps.

tidal kiln
#

^^ same for me

brazen cedar
#

@solar whale I'll give that a try

tidal kiln
#

do you have a boot.py file?

brazen cedar
#

@tidal kiln no boot.py only boot_out.txt

tidal kiln
#

ok. not that then. (was wondering if something was remounting the fs as read-only)

split ocean
#

Has anyone here run into a Errno 28 trying to launch Mu?

#

OSError: [Errno 28] No space left on device: '/Volumes/CIRCUITPY/images'

tidal kiln
#

@split ocean are you creating the /images folder? (there's a known bug for that)

solar whale
#

@brazen cedar whne CIRCUITPY mounts, check the output from "dmesg" and if it reports it as "read-only" then then, in my experience that usually means that the FS is corrupted.

split ocean
#

Ah. No @tidal kiln not intentionally.

#

I was doing some plotting any chance that creates an images dir?

solar whale
#

mu beta15 does that!

brazen cedar
#

@solar whale I'm a Ubuntu newbie, where do I find dmesg output?

split ocean
#

im in beta15 yes

tidal kiln
#

what's in that folder?

#

@brazen cedar it's just a command, run it from prompt

solar whale
#

just type dmesg in a terminal session. if you jsut mounted the CIRCUITPY it should be in the last entries - post the last few lines here

brazen cedar
#

ok

tidal kiln
#

can do something like dmesg | tail -10

brazen cedar
#

@solar whale ah ha! corrupted directory (invalid entries) set to read-only

#

@solar whale so how do I fix it?

tidal kiln
split ocean
#

Interesting, looks like there were .csv files being saved to the CPX in a data_capture dir. here's the code I'm running on the board

# 
import board
import time
 
light = analogio.AnalogIn(board.LIGHT)
 
while True:
    print((light.value,))
    time.sleep(0.1)
#

there is not an /images dir on the CPX

tidal kiln
#

mu might still be trying, and generating that message

#

and those .csv files have taken up all the space

split ocean
#

yes one of them is 1.7MB! is that even possible?

tidal kiln
#

are the csv files left over from something? like a data logging code you were running?

split ocean
#

not that I can recall

#

๐Ÿ˜ซ

tidal kiln
#

weird. and they are in a folder named data_capture ?

split ocean
#

yes, it seems running plotter may be the cause

solar whale
#

@brazen cedar if you have CP3.0 on the M4 you can erase the FS from the REPL if you ahve access to the REPL.

# 
storage.erase_filesystem()```
split ocean
#

OK, this is actually what I have running on the CPX

# 
import board
import touchio

touch_A1 = touchio.TouchIn(board.A1)
touch_A2 = touchio.TouchIn(board.A2)
touch_A5 = touchio.TouchIn(board.A5)
touch_A6 = touchio.TouchIn(board.A6)

while True:
    value_A1 = touch_A1.raw_value
    value_A2 = touch_A2.raw_value
    value_A5 = touch_A5.raw_value
    value_A6 = touch_A6.raw_value
    print((value_A1, value_A2, value_A5, value_A6))
    time.sleep(0.1)
#

and if I launch the plotter in Mu nothing gets saved to disk, but when I close the plotter it saves a .csv file to the CIRCUITPY/data_capture dir

#

which seems kinda cool but opaque of Mu to do this

tidal kiln
#

lemme see if i can recreate...

split ocean
#

I deleted the files and it seems to all be happy again

tidal kiln
#

@split ocean what are you doing to "close the plotter" ?

split ocean
#

press "plotter" button again

#

BTW, this might not matter, but I was actually running that cap touch code I posted above on this CPX, not light level.

tidal kiln
#

hmmmm. haven't closed plotter yet, but i have an empty csv file sitting in a data_capture folder.

split ocean
#

interesting.

#

i'm on mac os and was just watching a finder window, not actively checking that dir

tidal kiln
#

closed plotter. and now it has size, and data in it

split ocean
#

just checked in a terminal and it doesn't seem to make my .csv until closing plotter

tidal kiln
#

looks like a bug

split ocean
#

Neat feature, but it would be nice to specify!

#

"yes save .csv file" vs. "no thank you to .csv file"

tidal kiln
#

not sure if it's intentional, or it's not cleaning up after itself

split ocean
#

I think I left one running a long while, closed it, it saved the 1.7MB file, and then my troubles began

tidal kiln
#

and all your space was taken, and thus that error message

split ocean
#

right

tidal kiln
#

when the other "feature" tried to create the alien image file and sounds

split ocean
#

what caused that? is there an alien feature
?

tidal kiln
#

that issue i linked above. has something to do with pygame.

split ocean
#

got it

solar whale
#

I think thge "alien" stuff is related to "pygame" but leaked into it.

split ocean
#

thanks for the help, I'm in good shape now to shoot a plotter vidoe!

yeah. for now, just delete those csv files to get your space back.

SO bsx's reference is probably good, and also https://wiki.python.org/moin/BeginnersGuide/NonProgrammers. What you like will depend on your learning style. One problem is that once you get past the absolute basics, what you're learning may not be so applicable to CircuitPython in terms of libraries and applications. The basic language stuff is the same. But the projects in the beginner courses may take some framework or library as the thread for the examples that is not so relevant. I wish I could wholeheartedly recommend a particular book or course, but I've looked at a lot, and there's no clear standout. We sell the book "Python for Kids", and it's pretty good, but it's at more of a high school level or even above in terms of terminology sometimes. But it has a good pace.

@tulip sleet just to catch up here - my CPX board wasn't running anything but the lights on the board (green and red showing load ok and the one the changed colours based upon cap touch input - so there were 3 on board running all the time for um, say 45 hours which - yes the batteries are shot now I think for certain. So i didn't start getting the code wipe thing again after taping up leads away from each other - till around 43 hours of battery - so should reprogram to eliminate the on board light-up - would make it run a bit longer. but for perm install i would suggest wall wart or solar trickles if outside or port avail outside project for rechargeable battery or battery pack outside so it can be changed easily. --- although --- i could have still had people sticking hands inside and shorting it ou because it wasn't sealed up very well ===variables===kids sneaking a peek!!! ๐Ÿ˜‰

@warped pendant The little LEDs take very little current. It's the RGB ones that take a lot. 45 hours is impressive.

Oh hey, I spotted the problem.

If you look at py/makeversionhdr.py, you find:

def make_version_header(filename):
    # Get version info using git, with fallback to docs/conf.py
    info = get_version_info_from_git()
    if info is None:

So it falls back to using docs/conf.py if git isn't available. It's not in my build environment, and obviously nobody ever tested the fallback path since making that change in...

I looks like MQTT is not available on the CP ESP8266 port, v2.2.4. Is that right? MQTT is a built-in module for micropython on ESP8266. But, the same import on CP showed that MQTT is not built-in. I was able to work-around by adding the module from the micropython github library. Am I missing something? perhaps the built-in MQTT module has been re-named in CP?

Anyone using the plotter in Mu and finding it doesn't quite match the data you're getting in the REPL?

#

I have a potentiometer hooked up, and the pot maxes at 3.3 and the plot is sitting around 2.3 or something. I also just realised that the grid marks aren't quite right, at this scale, the first grid mark is 1 and the second one is 3. Which means the first space is 1 unit, and the second space is 2 units.

#

IF I have the pot at 1.9, it sits on the 1-line.

#

0 is correct.

@slender iron @tulip sleet did something change from 2..x to 3.0 regarding the default state for digitallio.Pull on an Input pin? I think this was the problem for the LORA driver - The way the initial RESET is done is a bit odd, it statrs with the pin as an inout then switch to output to pull it low. the code did not set the input to Pull.UP - on 2.x it seems to default to UP -- on 3.0 it does not. It works when I force it to Pull.UP

slender iron
#

@solar whale it possible we accidentally reset with pull up. I would expect it to be no pull by default

solar whale
#

I think that is correct, just wondering why it seems to work in 2.x

tulip sleet
#

In the 2.x code, it starts out with PULL_NONE and sets that again to PULL_NONE if you do switch_to_output. The drive mode is set to OPEN_DRAIN on switch_to_output() as well.

solar whale
#

is it different in 3.0?

tulip sleet
#

nope, looks functionally the same in 3.0. Both in common-hal/digitalio/DigitalInOut.c

#

stepping away for dinner but I'll look more in a little while

solar whale
#

In any case, it seems to work now - The REST was clearly not working the way it was. The whole reset scheme is strange and my be due to something odd about how it was working when it was written. It is very different from the rfm69 reset which looks more normal to me. Just sets it to output and drives it. For the rfm9x it sets is a an input the switches to output(low) then back to input. Tony's note just says it has to be done that way. I'll play with it.

Raising brownout voltage limit to 2.77V did not fix the problem. After testing by turning various things off, adding delays, etc., I think that the usual reason for this problem is the boot_out.txt write that happens on every hard reset. If the write gets interrupted by a power fail (or reset?), the filesystem is damaged and will be re-created on the next startup. If I turn off the boot_out.txt write, I cannot reproduce the problem.

I'm going to try it out later this evening with circuit python.

you can replace the time.sleep_ms or us with time.sleep(0.00001) or whatever

I don't think it actually matters

#

the delays only matter if the python can toggle faster the clock line faster than 2.5 mhz

#

bitbanging from python is slow

@slender iron mostly I am just trying to avoid modifying the tm1637 module more than necessary.

[adafruit/circuitpython] New comment on issue #280: atmel\-samd: Brownout / low battery causes SPI flash erase on Circuit Playground Express

@tannewt @dhalbert - you're welcome! Thanks for your work to make this all work so well. :)

More results:

  1. cpu-2v7-smart-boot_out does NOT wipe the filesystem. boot_out populates if the file is missing on startup as well. So both seem to be as expected, no wipe and boot_out populates.

  2. Voltage is 4.678 under moderate load, moderate being all 10 LEDs up and running. No LEDS is 4.8v.

[adafruit/circuitpython] Pull request opened: #804 3\.0: Handle bad power on reset\.

This is the 3.0 version of #802. Fixes #280 for 3.0. Fixes #651.

  1. Do not write boot_out.txt if there's no boot.py or equivalent, and the version info in boot_out.txt will not change.
  2. If there is a boot.py, wait 1.5 seconds before running it and writing its output to boot_out.txt.
  3. Change BOD33 brownout threshold to 2.7V for SAMD21 and SAMD51.

This makes bouncy switched and plugged power connections much less likely to erase the filesystem.

Are the modules in the top-level frozen/ directory supposed to be included in the build? They don't seem to be available. E.g., I see there Adafruit_CircuitPython_Thermistor, which includes the adafruit_thermistor module, but that's not available when I import adafruit_thermistor.

@bold agate those modules are only included in the CPX build, because it has onboard devices that use those libraries. Which libraries are frozen in which builds is configured in boards/*/mpconfigboard.mk.

bold agate
#

Thanks. Looks like there are no board definitions for ports/esp8266 (and the makefile doesn't reference one). I'll just move the ones I want into ports/esp8266/modules.

tulip sleet
#

right, the esp8266 Makefile and .mk files don't handle it in the same way. We haven't completely revised the esp8266 make structure to correspond to the atmel-samd one, which is more paramterized.

bold agate
#

Would you expect the adafruit_onewire module to work on an esp8266 board? Importing it I get a "Fatal exception 3(LoadStoreErrorCause):..."

[adafruit/circuitpython] New comment on issue #803: esp8266 port missing time\.\{sleep\_us, sleep\_ms\}

We're discussing in issue #519 about how and where to add more time functionality. @tannewt has suggested adding a precise_time module for functionality above and beyond time.

We are trying to move away from the u* modules in favor of more descriptive ones with a more consistent API. We either provide a subset of or the same functionality provided by a CPython module, or we come up with a new module that has its own API, not necessarily derivative in terms of naming

[adafruit/circuitpython] New comment on pull request #785: RFC: atmel\-samd/samd21: Rework clock setup \+ calibration

Version 2

Changes:

  • Split out clock code into samd21 and samd51 source files to enhance readability when later adding lots of clock code
  • Move the the clock representation from microcontroller to a new samd module
  • Add SysTick to the clock representation

The CALIBRATE_CRYSTALLESS knob feels a bit backwards since all boards can be run without the crystal. Or is it just some left over cruft, I can't find that it's used anywhere. How about defining ```HAS_CRYS...

#
dhalbert
[adafruit/circuitpython] New comment on pull request #785: RFC: atmel\-samd/samd21: Rework clock setup \+ calibration

Thanks for all this work. CALIBRATE_CRYSTALLESS in part invokes code that adjusts the calibration by comparing it with the host USB clock (which we presume to be quite good). The code is commented out in ports/atmel-samd/supervisor/port.c in the master branch, but is functional in the 2.x branch in atmel-samd/main.c. But yes, that switch should probably be distinguished from flags that say whether or not to use an onboard crystal.

Re samd: since we are also supporting ESP8266, ...

lethal abyss
raven canopy
#

@lethal abyss there is a Trellis library available. But, CircuitPython will not respond as quickly as an Arduino, especially with the lack of interrupt services. It's not super slow or anything, but there is some latency, which is dependent on the length/complexity of your code.

#

I've been meaning to compare the "speed" on the M4 vs the M0, but haven't gotten around to it yet.

manic glacierBOT
lethal abyss
#

@raven canopy at first, speed won't be major issue? it will be used with kids to demonstrate device / code / music. I just wonders if the M0 can be seen as a USB device as the Leonardo and if CircuitPython has methods for that

[adafruit/circuitpython] New comment on issue #803: esp8266 port missing time\.\{sleep\_us, sleep\_ms\}

I wouldn't be surprised if os_delay_us had a maximum time it will wait. Precise microsecond timing is whole different beast to timing out a second. Microsecond timing can only be done reliably with interrupts off while second level timing can leave them on.

Even if we did provide a way to measure 10 microseconds, the actual delay would be longer due to the speed of the VM. It does given you a minimum delay though.

[adafruit/circuitpython] New comment on issue #803: esp8266 port missing time\.\{sleep\_us, sleep\_ms\}

Devices that you clock yourself like the TM1637 are very flexible. You just
can't clock them too fast. However, clocking them slower makes the update
speed slower. They'll still work though. That's why I was suggesting
removing the sleep all together. :-) I doubt CircuitPython on the SAMD21
can bitbang faster than the 2.5 mhz maximum for the chip.

The SAMD51 might be able to though. I haven't measured it. In that case, a
delay is helpful to make sure it doesn't go too fast.

On Fri, May 4, 2...

@tulip sleet Does it take a bit for the uf2s to build and post to GitHub under the release?

tulip sleet
#

I do it by hand! In the works.

idle owl
#

Oh ok.

tulip sleet
#

I wrote the release first so I'd have a tag.

idle owl
#

Can I please get a CPX build then? ๐Ÿ˜ƒ

#

I haven't finished loading the boards and I could do it with 2.3 if I have the official build

tulip sleet
#

almost there. the builds just finished. I'm doing a smoke test on CPX.

idle owl
#

Ok!

#

I finished CircuitPython code for Sophy's lasercut con badge and finished assembling it. So now I have an amazing thing to be wearing at con ๐Ÿ˜ƒ

#

I think my slides are as done as they're going to be. Hopefully I actually got all the code up to GitHub. I realised I was making edits in the slides and not to the actual code at one point, which doesn't bode well for that having happened ๐Ÿ˜„

tulip sleet
#

@idle owl ok, release files all present! The editing issue reminds me when I was working on the HID descriptors I was changing values in the comments (only) and wondering why they didn't change in the code.

#

@onyx hinge there is something weird going on, but also those two builds seem to be running completely different build scripts

onyx hinge
#

@tulip sleet I see that now.

#

Running Sphinx v1.6.5
Running Sphinx v1.7.4

yah, we might have two build scripts going by accident

jade shuttle
#

hello does some one know the power consumption of the circuitplaygound express if the leds are all on?

idle owl
#

@tulip sleet Thanks!!

tulip sleet
#

@jade shuttle at 5V a full-on NeoPixel takes 60ma, so at 3.3V they may take about 40ma each. The rest of the board is a lot less (like a few 10's of ma). But having all the LED's at full brightness is blinding.

analog drift
#

If I need to communicate to a module over an SPI interface (given that I hooked up MOSI MISO SCK & CS), I would pull CS down and spi.write then pull up CS when I am done writing?

#

I would only need to configure it once with the following snippet? python while not spi.try_lock(): pass spi.configure(baudrate=5000000, phase=0, polarity=0)

#

Is spi.unlock() only used when you do not need to communicate to the module again without reconfiguring the SPI?

tulip sleet
#

@analog drift The locking is only there so that several devices can share the same SPI bus. You would pull the CS for a particular device down and then pull it back up when you're done. If you only have one device, you can leave its CS down, and not bother to unlock the SPI object.

#

Or even tie its CS line to ground and not bother to do CS changing in the program.

analog drift
#

Would holding the CS down prevent the device from receiving* data back?

tulip sleet
#

no, grounding it enables the device, so when you do a read, it's down as well.

#

the device will talk on MOSI and MISO, clocked by SCK, as long as CS is grounded

analog drift
#

Roger

tulip sleet
#

"CS" is "active low". If we had better typography, I would draw a line over it, indicating negation.

analog drift
#

Yea. I guess at this point I am blindly guessing in the dark attempting to communicate to an XBee module over the SPI communication protocol. Not sure if I set up the XBee wrong or I am just failing to communicate to the device. ๐Ÿ˜ฆ

#

I am holding down that pin low though. So I have that going for me. Other than that I am trying to send \x7E\x00\x1D\x10\x00\x00\x00\x00\x00\x00\x00\xFF\xFF\xFF\xFE\x00\x00\x44\x6F\x65\x73\x20\x74\x68\x69\x73\x20\x77\x6F\x72\x6B\x3F\x6F if that is a proper frame for the XBee communication protocol. (it is a copy paste generate frame from their setup application)

sorry - I don't know off the bat. have never used XBees before.

@tulip sleet here is the code i was trying to test my dotstar featherwing with - please note that it has worked for me before when i first tried it a few months ago - it is from @umbral dagger dotstar featherwing library/examples. i'm trying to get it running again because i want to use the featherwing in conjunction with my servo and pot which i have put together working code for and need to integrate the dotstar.

and here is the error the repl returned: Traceback (most recent call last): File "code.py", line 6, in <module> File "/lib/dotstar_featherwing.py", line 55, in __init__ TypeError: function takes 4 positional arguments but 6 were given

@covert birch I was playing with that... just a sec

covert birch
#

oh cool

umbral dagger
#

I was using CP 3.0 alpha 4

#

self.display = adafruit_dotstar.DotStar(clock, data, self.rows * self.columns, brightness=brightness, auto_write=False)

#

brightness and autowrite need to be named now it seems

covert birch
#

ohhhh, at first i thought what is that - should i be using that or stick with the 2 beta?

umbral dagger
#

What board?

covert birch
#

feather mo exp

umbral dagger
#

Stick with the latest 2.x for now IMO

covert birch
#

ok

umbral dagger
#

But look at the dotstar code. I think just autowrite needs to be named.

#

I was playing around with it using 3.0 on the Metro M4... much snappier ๐Ÿ˜ƒ

covert birch
#

nice. how long do you think till 3 is ready? will i be able to use on my board?

umbral dagger
#

Does anyone know off the top of their head how to check whether a file (using sd/storage/os) is a directory or regular file? os.path doesn't seem to be there.

#

@covert birch I expect it will work fine. Not sure of timeline, it looks to be making good progress, though./

covert birch
#

cool. it sounded like it on aae this week

#

so, @umbral dagger , would the autowrite go in the () with the pins and brightness? like autowrite.True?

umbral dagger
#

@covert birch like I posted above. That was from my running code

covert birch
#

ok, i'll try it

#

i must not've been paying full attention to your code snippet - a little brain drained

tulip sleet
#

@covert birch The library will work with either 2.x or 3.0. You can still with 2.x for now.

covert birch
#

ok @tulip sleet . @umbral dagger , am i supposed to add that line of code or replace the wing line with it? i'm getting the same error as before and mu says everything is unnamed

umbral dagger
#

replace the previous 'self.display =' line

covert birch
#

from the library file?

umbral dagger
#

in dotstar_featherwing.py

covert birch
#

thank you. it works. like i said, i'm a little brain drained

#

excellent, now i just have to get my custom dotstar file to work by itself and then with the servo and pot code... i'm sure i'll be back...

umbral dagger
#

As for my is_dir question, I couldn't find anything so ended up writing it:

     try:
         os.listdir(path)
         return True
     except OSError:
         return False

@slender iron I quickly found that in cpython. Couldnโ€™t find os.path in CircuitPython.

onyx hinge
#

It's ugly, but I believe you can also detect a directory with: os.stat(path)[0] & 0x4000, again with error handling for the case where stat gets an exception due to the path not existing.

extmod/vfs.h:#define MP_S_IFDIR (0x4000)
