Currently removing stuff is somewhat ad hoc. You'll want to look at ports/atmel-samd/mpconfigport.h and maybe boards/trinket_m0/mpconfigboard.h

@cunning trail in reading the article, and looking at Debra's blog, seems that for the handbags/headbands she's using the Gemma (naturally..best fit). To get around the file size with hardware, ItsyBitsy M4 would be the closest wrt size constraints. Then there is also Roy's pixelbuf work that may help on the M0 too. Having said all that, MakeCode seems the "better" suggestion in the interim?
tulip sleet
@obsidian dome you may want to use the 3.x branch right now instead of master, which is undergoing churn as we develop 4.0
obsidian dome
danh: Thanks. I'm looking into it. Right now I'm setting up a VM for building.
tulip sleet
Feel free to return here for help. A number of folks who hang out here have done their own builds
obsidian dome
Looks like I can easily loose touchio, i2c and SPI for my project
raven canopy
@obsidian dome what OS are you on?

k. i was going to suggest WSL if you're on Windows. Its the "fastest" compile time-wise.
interesting. anyone else stumble upon this recently?

Any suggestions for how to determine which modules use the most space?
ruby atlas
I saw they announced it, but wasn't aware it was available yet.
raven canopy
still beta, but it showed up on the CP repo. (which is how i came across it)
ruby atlas
@obsidian dome hmm.... i wonder if the object sizes are useful there.
obsidian dome
That's what I was thinking, but sometimes small objects have massive dependencies in code. Don't know if circuitpython will be like that.
ruby atlas
find build-metro_m4_express -name \*.o -ls
That's why I wondered about it.
build-metro_m4_express/firmware.elf.map might help
(use your build dir instead)
I can't remember if the map is produced if you don't use DEBUG=1
obsidian dome
Kudos to whoever manages the circuitpython repo. Once I got to the learn page it all worked like a charm. The only trivial issue was checking out 3.x as three directories from master (lib/tinyusb, ports/nrf/nrfx, tools/huffman) weren't empty. But hey, I know now to rename a directory. Again, kudos for a good tutorial and process.
ruby atlas
yeah, I still refer to the debugger setup instructions page instead of remembering it. I ❤ Adafruit Learn.

sounds like you didn't create the i2c bus
do you have a line of code that looks like this?
i2c = busio.I2C(board.SCL, board.SDA)
oh... right :)
The problem was I jumped to the Led Backpack in the doc and forgot this line. Thanks
tidal kiln
np. what doc are you reading?
tidal kiln
hmmm. yah, that's written so the individual sections aren't really code complete.
lethal abyss
that's easy to jump that line (I saw the import lines just before)
tidal kiln
yep. the "I2C Initialization" section applies to all the displays - the sections that follow
take a look at the examples in the library also:
https://github.com/adafruit/Adafruit_CircuitPython_HT16K33/blob/master/examples/segments.py
having complete code to look at helps

oh nice, I was looking for example like this but was looking for something with the name of the library I use (adafruit_ht16k33)

If the esp 32 has two cores can Cp run on just one? (Just conjecture. Not request or suggestions)
Leaving the other available for wifi sterf ?
stuck elbow
I didn't know thete was CP for esp32
solar whale
There is not and there is not likely to be...
solar whale
@marble hornet some interesting stuff on using both cores with Arduino https://www.hackster.io/rayburne/esp32-in-love-with-both-cores-8dd948 --- I did some quick google searches for micropython on dual cores and there appears to be work on this. I did not dig too deeply.
meager fog
@umbral dagger hey hey
the guides are ready to live in a min...but i was wondering, i think the debouncer should go in a helper library no? seems like ya use it alot?
umbral dagger
@meager fog Yeah, we'd mentioned that. Kattni and I are going to sit down and talk (me) through it to make it happen. Just haven't gotten mutual time to do that yet. There's a couple tweaks I want to make to it to make it more generally useful. It's on my list for the new year. That said, it's getting a fair bit of testing.
meager fog
kk its not too hard - i have a checklist
if ya can, for the garmin guide, can you take a 2-3 sec gif of you spinning it in your hand so we can see the lens part?
like turning it around so you can see that there's a lidar sensor on the other side 😃

What is the maximum pwm frequency for the M4 in circuitpython?
For example in the code "led = pulseio.PWMOut(board.D13, frequency=5000, duty_cycle=0)"
exotic pumice
I can't quite recall but I think it's like 20-50KHz-ish or less
it's definitely in the KHz range
hearty edge
First time here... Looking for some help with libraries. Not sure how to change default settings. For example - changing the range on the L3GD20 gyro.
meager fog
nav, check the docs here https://circuitpython.readthedocs.io/projects/l3gd20/en/latest/api.html
marble hornet
@solar whale thanks for the link!
Separately:. Is there a good reason to go 32 over 8266 when doing cp wifi?
meager fog
yes esp32 can to secure connectiosn better/faster
hearty edge
Thanks, but my mechanical engineering background is showing. Tried
sensor = adafruit_lsm303.LSM303(i2c,rng=0)
and got back TypeError: unexpected keyword argument 'rng'
umbral dagger
@meager fog Converting a spin gif now. Where do you want it?
hearty edge
Apologies...being a dingbat. I am working with both. Trying to use my Metro Express with ZumoBot.
umbral dagger
@meager fog have a look
tulip sleet
@hearty edge adafruit_lsm303.LSM303() only takes an i2c argument, not a rng argument. Just take that away for now.
hearty edge
@tulip sleet Thanks - got that. Now trying to write set a register on L3GD20. Trying SENSOR.write_register(_L3GD20_REGISTER_CTRL_REG1, 0x0F) and getting a NameError.
Fubling my way through "class" and "parameters"...
tulip sleet
@hearty edge the _L3GD20_REGISTER_CTRL_REG1 value is not available (normally you'd use SENSOR._L3GD20_REGISTER_CTRL_REG1) because it's a compile time const due to special rules (it's set via const(...)). Do you need to set the register yourself? We already set it to 0x0f in __init__()
hearty edge
@tulip sleet Thanks again. What I am really trying to do is to get a handle on how to use the libraries to control the different aspects of the sensors. I would like to have my students - mechanical engineering sophomores - to use these devices so I am trying to do a deep dive. I am trying to decide how much background info I need to use a given sensor and its associated libraries. I don't want to treat them as "black boxes"
tulip sleet
@hearty edge I have to go out for a while. I'd suggest starting with the current driver and then modifying it, as opposed to using it as it is, because it's set up for a particular style of use (hence you can't write the registers yourself).
tidal kiln
@hearty edge the library is too much of a black box in this case? you're going to want them to understand the registers?
hearty edge
@ @tidal kiln @tulip sleet I guess that the ideal thing would be to have some more examples that could be used to explore the capabilities of a sensor. The libraries reference the information provided on the data sheets, but it's not obvious to a novice how to explore/implement the functionality.
tidal kiln
sounds like maybe the examples are too simple?
or is there functionality of the sensor that is not currently implemented in the library?
hearty edge
@tidal kiln Examples are too simple (IMO)... The libraries look to be very complete.
tidal kiln
ah. ok.
it's a trade off
for each library we want to have, at a minimum, a "simple" example that truly is very simple
not much more than a "hello world" for the sensor
some libraries will have additional examples that explore things further
or maybe covered by guides in the learn system
marble hornet
the 840 has zigbee!?
hearty edge
@tidal kiln BTW - I am a BIG fan of everything Adafruit has done and continues to do. I just usually approach learning things with the idea that I will eventually have to explain it to someone else. What I need to do is to get more proficient with Python. Do you have any recommendations that would be particularly geared towards Circuitpython?
marble hornet
did the 8266 support wifi in 3.1.1? or just running on it
tidal kiln
anything Python would be fine, it should translate fine to CircuitPython
CP tries to do everything in a way that's backwards compatible with CPython - which is what you're probably running on a PC
this tries to explain some of the main differences:
https://learn.adafruit.com/circuitpython-essentials/circuitpython-expectations#differences-between-circuitpython-and-python-18-7
meager fog
@hearty edge we do have a guide that shows going thru a datasheet to make a sensor driver. python's a lil different than C but i find it easier to code sensor drivers in python
that may be helpful so youc an see the 'thought process'
tulip sleet
@marble hornet it does support wifi, using mostly the MicroPython supplied modules
@hearty edge for books, if you're already a programmer, I can suggest:
https://www.amazon.com/Python-Nutshell-Desktop-Quick-Reference/dp/144939292X/ (front section has a concise introduction)
https://www.amazon.com/dp/0321680561/ (somewhat out of date (early Python 3.x) , but well written)
https://www.amazon.com/dp/1617294039 recommended by others but I have not looked at
hearty edge
@meager fog Thanks! I'll take a look. BTW - Congrats on the Forbes Top 50.
meager fog
nav, thanks - and if you end up writing drivers let us know we'll include in the bundle! 😃
hearty edge
I'm an ME so not likely, but maybe a tutorial or two as I figure things out....

@tulip sleet mircopy code on cp for wifi ?
sinful sand
I'm building a model theatre for my daughter (Previously posted in #help-with-projects ). I want to have sound, lights and servo or motor control. I have a TrellisM4 which gives me the sound capability and the buttons to control everything. It has been suggested I buy an Itsy Bitsy to run the neopixel LEDs that will be the stage lights and the servos/motors to raise/lower the curtains. Can I connect the Itsy Bitsy and the TrellisM4 over I2C? How would I go about passing a key-press event on the TrellisM4 to the Itsy Bitsy to say, change the colour of the neopixels? Or actuate the servo?
ruby atlas
One option would be to use serial
sinful sand
@ruby atlas Ok. I am a novice with CP. I have read through a learn guide on I2C - SPI but it was about connecting a sensor not microcontroller to microcontroller. Are you aware of any sample code that may give me a starting point?
ruby atlas
The JST port can be used as I2C, ADC, or UART.
https://www.adafruit.com/product/3938 Finally, a 4 pin JST hacking port is available for extra add-ons. It's STEMMA and Grove compatible, and provides GND, 3.3V power, and two pins that can be used for I2C, ADC, or a UART. So connect some other sensor, or read stereo audio in, or maybe hack together a MIDI port. Whatever you like!
https://www.adafruit.com/product/3800 can be powered from the 3.3v of the STEMMA port making it a single wire bundle (4 wires) to connect the two boards.
steep moth
The ItsyBitsy M4 Express can also play audio files.
ruby atlas
There are sooo many awesome boards 😃
steep moth
I ❤ my ItsyBitsy M4 Express. I can't wait to get the Adafruit Grand Central.
ruby atlas
You could also probably just use the Trellis M4 to control everything.
umbral dagger
@meager fog Will do. After dinner.
marble hornet
@steep moth I have the same sentiment about the itsy m4
Aren't they great!
But that gc m4 🤤 more wam
sinful sand
That looks useful and I will read with care. I would be grateful for any code samples that specifically detail passing a key-press event on the TrellisM4 to an Itsy Bitsy. @ruby atlas Can I connect neopixels to the TrellisM4?
ruby atlas
Signed up for the Adafruit Grand Central!
steep moth
They are awesome, I started to use mine with Circuit Python, but I found it easier to accomplish my goals in Arduino, so I started using my M4 in Arduino.
ruby atlas
@sinful sand yes. Let me find the pinout details. Neopixels just need data and power.
steep moth
I hope the Grand Central is not too expensive. I think it will probably be around $40, which is kind of out of my price range.
marble hornet
What is this Arduino you speak of, I've Never heard of it?😉
My guess is 35 🤞 but once it is out one could easily make their own (via copy)
Like as part of a project
sinful sand
I bought my TrellisM4 because of the M4 chip, the large memory, the sound capabilities and of course the LEDs/buttons!
ruby atlas
hrm, i can't find the pinout details for the board beyond a few mentioned on the learn guide.
marble hornet
Is the trellis m4 256 k ram or 192?
ruby atlas
i don't feel like figuring out how to read the board/schematic file 😃
steep moth
"512 KB flash, 192 KB RAM"
sinful sand
I have had a lot of fun with mine - who doesn't love light-up buttons.
steep moth
It now has a new silkscreen on the back.
ruby atlas
Trellis M4 = SAMD51G19A, GD25Q64C flash. Metro M4 = SAMD51J19A, S25FL116K, S25FL216K, GD25Q16C flash.
(per boards/*/mpconfigboard.mk)
Same chip so same ram makes sense.
sinful sand
I saw that. I think I'm glad I have one of the 1st ones.
ruby atlas
I have one from the adabox010 and 2 more for the kids I got shortly after that also ahve the fancy silkscreen.
I've got one currently doing an FFT spectrum analysis of the music pumping out of my mixer to my office 😃
sinful sand
They do look nice.
ruby atlas
They were out of stock on the acrylic cases, so I designed an OpenSCAD 3d printable case.
sinful sand
I can't see a way of controlling neopixels and a servo with just the JST/STEMMA port. Other than via another MC.
ruby atlas
You'd have to send control sequences to something like the trinket.
sinful sand
More thought required and hopefully some example code to connect two MCs. Off to bed now, it is late in GMT land.

There was another community member communicating between two Itsy Bitsys but I don't remember who.

@ruby atlas -- you can use teh library from here (I htink it is in the latest bundle as well) and the demos in the examples should work -- see the demos code for the pins to wire up -- GPIO15 is critical for flow control - you need to connect RX,TX,VUSB,GND,GPIO15,RESET from the ESP32 to the metro M4 -- swap RX/TX - use the recommended or any other GPIO for the GPIO15,RESET(edited)

with the j-link mini edu, you can run the gdbserver also and use the load command

Hi
raven canopy
hey @timber mango! 👋
halcyon wolf
@exotic pumice I watched the video...very interesting....I must explore further. Like Mike, I'am far more used to C/c+ and java than python. I watched another presentation by the creater of micropython and it's apparently being used in some serious stuff. Interestingly he did question the need for circuitpython as an "easier" version of python.
timber mango
I try to write a driver to use the M4 board as two neotrellis
to be able to put everythong in one multitrellis instance
so I try to understand how neotrellis (with Seesaw) works to do the same with the trellis M4
raven canopy
i haven't used or delved too far into either of them, yet. i imagine you could interface them over I2C with the Seesaw (SAMD09). are you on working on the C side or the Python side?
timber mango
only on the python side
but I need to understand what data the seesaw is sending over I2Cto code the same behavior on the trellis M4
solar whale
@pastel panther Thanks for reviewing/approving the rfm9x. If you have time would you also take a look at thr rfm69 -- same fix https://github.com/adafruit/Adafruit_CircuitPython_RFM69/pull/14 -- cut/paste is dangerous thing 😉
marble hornet
hey, i'm looking to use this: https://www.adafruit.com/product/1400 to switch power in project (the tricorder) but the button can't be physically pressed. i see that the output of the nand gate is connected back to the input by a not gate. can it be hacked into it somehow? else could i please have some mosfet help 😅 (i'm not great at them) . other suggestions welcome too. thank you either way
please 😅 😀
i have a capacitive touch sensor as an input rn
raven canopy
@timber mango in looking at the NeoTrellis library, seems that it's just using the Seesaw library. So, that should give you some insights.
NeoTrellis importing Seesaw: https://github.com/adafruit/Adafruit_CircuitPython_NeoTrellis/blob/master/adafruit_neotrellis/neotrellis.py#L51
Seesaw library files: https://github.com/adafruit/Adafruit_CircuitPython_seesaw/tree/master/adafruit_seesaw
solar whale
@marble hornet so you want to replace the pushbutton with your cap. touch switch?
solar whale
so - can't you just do that in the circuit? or is the cp touch also powere y the same source. Is that the problem?
marble hornet
the cap touch is separate (it's the same regulator output but turning off the rail to the m4 and sensors )
i'm just really bad at using mosfets and transistors (smd) i can rarely get them to work. the m4 and such will draw more current than the cap chip can provide
solar whale
right -- I am by no means an expert on ths, but it looks likea good place for a transistor -- the Cap touch would just turn the transistor on/off to close/open the point where the pushbutton is. Does that make sense?
solar whale
I would think momentary -- just like the pushbutton
while the button/captouch is pressed, the circuit is closed.
upbeat plover
is it possible to remap TX and RX? was thinking of putting a feather and hallowing together but the RX and TX will be in same place.
i already tested so if anything crazy happens when i connect the two running different stuff, hallowing was running slide show, and adalogger was logging sensor data
marble hornet
in addition to the pushbutton! okay now i;m on the same page.
solar whale
or instead of it -- I was just saying that the pusbutton action is more like momentary than toggle.
it makes contact while it si pushed
marble hornet
i have a bunc of these laying around. (i agree, i though the transistor was replacing the pushbutton board, now i see what your'e thinking, 👍 )
solar whale
ok -- I thought just just wanted to hack into that board.... may be a much simpler way to do it.
solar whale
there may be a much simpler way just using the cap touch and a transitor or mosfet alone.
solar whale
I was focuse d on how to tap into the circuit you posted -- not on the implmentation
you might want to jump over to #project -- there are some folks there who may be of great ehlp.
ruby atlas
wheee:
WARNING: CPU could not be halted
Failed to halt target device on connect```i was light on implementation description. however the hacking would be quite fun. (too space inefficient though if just a transistor would work)
thank you @solar whale i'll take a jump over

{ MP_ROM_QSTR(MP_QSTR_TX), MP_ROM_PTR(&pin_PA10) },
{ MP_ROM_QSTR(MP_QSTR_RX), MP_ROM_PTR(&pin_PA11) },
solar whale
thats what I meant
upbeat plover
i change those two right?
exotic pumice
I think you just figure out which pins are available to be tx or rx on the sercoms and then tell busio to make a uart out of them
upbeat plover
TX and RX are not something specail just name of pins? i can just change code around and it works?
exotic pumice
The code you pointed at is just binding the names
They can only be sercom pins
There's a script somewheres that tells you which
upbeat plover
one board id do this ?
busio.UART(TX, RX, baudrate=115200, timeout=3)
and other board this?
busio.UART(RX, TX, baudrate=115200, timeout=3)?
solar whale
@upbeat plover since the pins are physically tied together, I don;t think you can use them to communicate between the boards.
since thay have to cross over between the boards to work.
upbeat plover
okay ill have to do something else then, like use a statemachine and just check up or down between pins
exotic pumice
The link I posted is a script that tells you which pins can be UART
upbeat plover
@exotic pumice i ran script has long printout
solar whale
perhaps I'm wrong -- if you rediine the pins on one side to swap RX/TX, then I think it should be OK - pin is just a wire.
upbeat plover
D0 is not a TX pin so i dont think i can just switch code around
solar whale
yo would have to rebuild CP with swapped pins on one board
exotic pumice
If the script tells you you can, you can. That's the magic of sercoms
exotic pumice
It's from the guide here https://learn.adafruit.com/circuitpython-essentials/circuitpython-uart-serial
upbeat plover
hmm ill have to run it on hallowing but looks like i can use different pins and do what i wanted
exotic pumice
Yep, whatever pin combos the script tells you, just do busio.UART() and you have a new UART
Getting rid of the old one is a separate problem
I guess that's actually what you want. Sorry.
upbeat plover
How do you get rid of old ones?
exotic pumice
I guess it probably uses the one bound to the name like you were showing before as the main one
MP_ROM_QSTR....
upbeat plover
okay so in pins change those to the new ones i see?
exotic pumice
Try it and see
upbeat plover
alrighty
exotic pumice
I've never done it before
upbeat plover
might take a bit, but ill update once boards are running changed CP
solar whale
@upbeat plover which board are you runnig the modified CP code on?
upbeat plover
both
hallowing and feather M0 adalogger, changed both D6 to TX and D10 to RX
building now
solar whale
OK but I' confused don't you want to cross TX/RX between the boards
upbeat plover
oops orignal problem forgot to switch lol
solar whale
and you can't use D0/D1 on those boards? just swap on one of them?
upbeat plover
hallowing d6 = TX d10= RX, adalogger D6= RX d10 =Tx
have yet to test anything came here with my thoughts first
D0 would not have worked not a sercom
solar whale
on which board?
upbeat plover
both its not TX
solar whale
ok -- I was looking at a diferent board (ItsyBitsyM4) it is on that one.
upbeat plover
anyone have a simple script to test this with?

@idle owl i was listening to the weekly again and wow that was an impressive amount of work you did !

@upbeat plover ah -- now I see -- not on hallowwing -- too bad.
upbeat plover
moddified CP on both boards now
solar whale
oos -- ignore taht old version -- just a sec
@upbeat plover here is the alpha5 compatible version ```import board

if(response == b'' or response == None ):
getresponse=False
Invalid Pins😬
solar whale
??
upbeat plover
yeah no clue why, im gana edit build and see if i remove the D6 and D10 and only have the PA to RX and TX
solar whale
where do you get the "invalid" pins message?
upbeat plover
line 8
solar whale
post the code you are running
upbeat plover
i copy pasted the alpha5 , where the time is 3 and not 3000
solar whale
but did you remap RX/TX in your build -- try using D6/D10
upbeat plover
building new CP right now with D6 and D10 removed and only having them as RX and TX
okay, ill try default CP next with D6 and D10 defined where they go
solar whale
that is what I meant -- use D6/D10 in the script - with your modified CP
timber mango
@raven canopy thankyou. I'm looking at the seesaw lib but I don't fully understand what the seesaw keypad does and send over I2C
I guess I have to experiment a little with neotrellis first
upbeat plover
@solar whale everything i try gives invalid pins for line 8
even current CP build with RX and TX pins lol
solar whale
so in the script you replaced RX with D6 and TX with D10 -- in both places
meager fog
@tidal kiln heya i can review the guide now

Hi all
I new to IOT 😃, but have been lurking on adafruit.com for some months now looking components and guides over. It's been ~10 years since I did C# and VB.NET development, so I thought CircuitPython was a good place for me to start anew. As a first project I want to read (using the https://learn.adafruit.com/using-ds18b20-temperature-sensor-with-circuitpython/hardware guide) temperatures from some 1-wire DS18B20 sensors I have been using with my smart house installation (www.loxone.com) and post these to a API interface on the smart house controller. I have therefore purchased a Feather HUZZAH ESP8266 board and have successfully flashed it with CircuitPython 3.1.1. My next step was to connect board to my WiFi network, but I'm not actually sure how to do that using CircuitPython as the most relevant guide, I have found so far, (https://learn.adafruit.com/adding-a-wifi-co-processor-to-circuitpython-esp8266-esp32) assumes that the Wifi board is the HUZZAH ESP8266 Breakout board running ESP8266 AT firmware and being managed from a Feather M4 Express running CircuitPython.
Is is unrealistic for a newbie like me to do everything on my single Feather HUZZAH ESP8266 board running CircuitPython?
upbeat plover
is there some kind of check in busio im missing?
meager fog
doc, you could - but we are sorta moving away from useing the bare esp8266 with circuitpython... might be better to try micropython for your project
solar whale
@upbeat plover -- what happened?
meager fog
doc, this is the only circuitpython wifi on esp project we've published https://learn.adafruit.com/circuitpython-totp-otp-2fa-authy-authenticator-friend/software - but it did work
upbeat plover
invalid pins still, i tried current CP and just do RX = board.D6 and it fails
stuck elbow
@hexchat the wifi stuff is the same as for micropython, so you can use those guides
upbeat plover
but when i run the UART_Test_Script it says D6 is both RX and TX
solar whale
I think that measn it can be either, but it is defined as one of them
upbeat plover
it fails and says Invalid Pins if RX is anything other then PA11
warm spoke
Thanks ladyyada. I'll have a look at the 2FA TOTP guide 😊
upbeat plover
or TX anything other then PA10
ill think ill just do as you suggested and cut and jump, make it cross pins physically
solar whale
taht is on current CP -- on which board -- hallowing?
upbeat plover
yea hallowing
solar whale
taht is how it is defined on adalogger
rX = PA11, TX = PA10
not on Hallowing
on Hallowwing RX = PA09 TX = PA10
@upbeat plover I have to go AFK for awhile -- I suggest double checking how things are defined -- good luck.
upbeat plover
on both boards it wont let me change RX or TX
valid falcon
I think this is a very basic question but I've been struggling with it and would appreciate some help. I'm using the Hallowing and using capacitive touch to trigger an led blink. Using the built in led on pin 13 works as expected but when using an external led through any GPIO the light is on by default and then blinks as expected with touch. I'd like that led to be off by default. I think I need to pull it down but haven't been successful as that doesn't seem to work on outputs. I checked and the touch value is responding as expected. Here's a simple example: https://gist.github.com/pdbartsch/c01440f60d5d9c24917bc1820cd3b664 Thanks in advance!
upbeat plover
im going to delete my CP and get from git again
steep moth
@valid falcon How do you have the LED wired up?
valid falcon
@steep moth positive to 3v and negative on GPIO pin 9
steep moth
Try connecting negative to GND and positive to GPIO pin 9.

@tidal kiln its in init?

ruby atlas
At least a 3 B+, several 2s, and at least on pre-2 model.
meager fog
yeah
tidal kiln
ok. now that i'm up to speed....PR looks fine. basically just adding in those other possible values.
upbeat plover
I was using wrong pins looks like D1 and A3 will work with just code no CP changes
feather_m0_adalogger; RX = A3, TX = D1
hallowing_m0_express; RX = D1, TX = A3
solar whale
@upbeat plover nice! I guess it's OK as long as neither pin is the same on both.
upbeat plover
so if i got that code running on one and send this from other i get this
>>> uart.write(bytes("hello"+"\r"+"\n","utf-8")) 7
solar whale
@upbeat plover AS for stacking feathers (not wings) in general, I was concerned there were some possible conflicts on some of the power/battery pins -- I don't see any problems, but it's worth checking carefully
solar whale
definately don't ever power both!

So what's a warranty bit? Does it void if you overclock or something?
raven canopy
i forgot how painfully slow the build is in Vagrant VM. even after i bumped the available memory in vmware. 😴
ruby atlas
interesting, builds are about the same speed in parallels for me.
raven canopy
VirtualBox* (maybe that has something to do with it?)
ruby atlas
do you have VT-x enabled? (and/or VT-d)
raven canopy
i don't think so. read some warning somewhere when i started with the vagrant, iirc.
ruby atlas
VT-x significantly speeds up virtualization by reducing overhead
assuming virualbox supports it
i haven't use vbox in a long time
raven canopy
vbox does. vagrant seems hit or miss in my re-googling.
ruby atlas
vagrant should use whatever virtualization you tell it to use
raven canopy
well, it seems to be picky on implementation...
and, yes, VT-x/AMD-V is enabled. 🤷
on Windows, and vagrant+linux VM doesn't support Hypervisor; which is what i was conflating with VT-x
raven canopy
hmm. this note from Vagrant may be a bigger issue, actually:
Windows users: NFS folders do not work on Windows hosts. Vagrant will ignore your request for NFS synced folders on Windows.
(i use vagrant for shared folders, since i debug in Atmel Studio vs gdb)
upbeat plover
when stacking feathers i get an issue "OSError: no SD card"
but when they are not stacked everything works fine
here is code for feather
import board

import time
uart = busio.UART(board.A3, board.D1, baudrate=115200, timeout=3)
uart.write(bytearray('hello'+"\r"+"\n"))
it writes so fast i dont even notice LEDs change most of the time
ruby atlas
are you stacking two feather m0/m4 boards, or two wings on a board?
tidal kiln
@upbeat plover the hallowing isn't really a wing, so you can't stack it on a feather
steep moth
You might have to cut some pins. The hallowing is probably causing interference on the spi lines.
upbeat plover
sck is the pin
i checked all pins
@tidal kiln so far these two seem okay with eachother, ill have to test more like TFT and sensors and all that
raven canopy
@upbeat plover i think what ArduinoUno17 and cater are saying, is that if you have the full header pin connecting both boards, then SCK/MOSI/MISO are connected on both boards. this may be causing some signal interference on the Adalogger when it tries to communicate with the SD card; the Hallowing's SPI pins may be sinking the voltage low. recommend that you only have power (V/GND) and UART (RX/TX) connected between the two boards...

just looking at itsybitsy m4, very cool that swclk and swdio are first class pins
I gotta get me one of them
now I see why you guys mentioned the itsybitsy when I was looking into making a swd implementation
solar whale
@upbeat plover @raven canopy regarding the stacked feathers, it should be OK to stack SCK,MISO,MOSI -- they are a bus and are norammly shared amond all SPI devices. I'd look elsewhere for the conflict.
upbeat plover
it was SCK, i detached it and so far no further problems
solar whale
hmm -- I guess that makes sense now that you mention it -- only one board can provide the clock. wings dont do that. .. there is more to stacking feathers than meets the eye -- be careful out there....
upbeat plover
yes for sure, i was going to try m4 but couldnt even find good pair of pins for TX and RX
exotic pumice
@upbeat plover I think the same script for finding tx and rx would run on m4
upbeat plover
yeah it does, i mean pair for both boards that line up well when stacking
exotic pumice
oh I see
upbeat plover
Hallowing has accelerometer, TFT, and external si7021 sensor all going, sending; temp, humidity, x y z G, and Lightsensor analog value over UART to adalogger and adalogger puts that all in a txt file on SD card
really seems like its working so far

So I'm new at this but not programming, I'm using a CPX and i want it to throw some keyboard commands when I hit real momentary pushbuttons so my F/A-18E's APU will be just like the real one. Anyway here's my code:
import time
import board
import digitalio
from adafruit_hid.keyboard import Keyboard
from adafruit_hid.keycode import Keycode
kbd = Keyboard()
apu = digitalio.DigitalInOut(board.A1)
apu.direction = digitalio.Direction.INPUT
apu.pull = digitalio.Pull.DOWN
while True:
if apu.value:
kbd.send(Keycode.A)
else:
print(apu.value)
time.sleep(1)
problem is all I get back is false.
I have a normally open momentary hooked to ground and A1
but oddly enough, if I take it to the REPL, I can get apu.value of false and I get true when I press it. I must be missing something real easy. Sure enough it was easy. Momentary switches need to be pulled up and then given an IF not statement instead. Like So:import time

from adafruit_hid.keyboard import Keyboard
from adafruit_hid.keycode import Keycode
kbd = Keyboard()
apu = digitalio.DigitalInOut(board.A1)
apu.direction = digitalio.Direction.INPUT
apu.pull = digitalio.Pull.UP
while True:
if not apu.value:
kbd.send(Keycode.A)
time.sleep(1)
kbd.release(Keycode.A)

hello, if I have questions to the usage of a circuitpython-lib, where should I ask?
I try to run the example of the adafruit_lidarlite circuitpython lib, but the only thing I get, are exeptions. The LIDAR works with the Garmin Libs (and same wiring) without problems ...
solar whale
@light plaza this is the place to ask -- post your code and the error messages and people will try to help when they are online.
also let us know what microcontroller board you are using and what release of Circuitpython.
light plaza
Feather M4 Express, CircuitPython 3.1.1 with the Library-Bundle.
code (lidarlite_simpletest.py):
import time
import board
import busio
import adafruit_lidarlite
Create library object using our Bus I2C port
i2c = busio.I2C(board.SCL, board.SDA)
Default configuration, with only i2c wires
sensor = adafruit_lidarlite.LIDARLite(i2c)
Optionally, we can pass in a hardware reset pin, or custom config
#import digitalio
#reset = digitalio.DigitalInOut(board.D5)
#sensor = adafruit_lidarlite.LIDARLite(i2c, reset_pin=reset,
configuration=adafruit_lidarlite.CONFIG_MAXRANGE)
If you want to reset, you can do so, note that it can take 10-20 seconds
for the data to 'normalize' after a reset (and this isnt documented at all)
sensor.reset()
while True:
try:
# We print tuples so you can plot with Mu Plotter
print((sensor.distance,))
except RuntimeError as e:
# If we get a reading error, just print it and keep truckin'
print(e)
time.sleep(0.9) # you can remove this for ultra-fast measurements!
The error-Messsage(s):
Measurement failure
solar whale
@timber mango I don't see anything obvious -- hopefully some familiar with that sensor or the library will be online later. Do you have the RESET line wired in - Does the Garmin Software use that?
light plaza
@solar whale No, I do not have the reset-line wired in.
I have only the 5V, GND, SDA and SCL lines wired and I have attached two pullup-resistors to 3.3V and the capacitor, that the LIDAR manual shows.
If I use the same configuration for a L3GD20 sensor and change only the SDA and SCL wires, I2C works as expected with the circuitpython adafruit_l3gd20 -lib.
If I have the LIDAR wired and exchange the feather M4 with feather M0, that runs the Garmin Arduino Lib, the LIDAR works fine.
So it seems, that the only thing, that does not work, is the adafruit_lidarlite. But I cannot imagine this, because it would be the first time, that a adafruit - lib does not work ...
solar whale
@timber mango Is it a 5V device or 3.3V -- the Feather M4 expect 3.3V signals for I2C
light plaza
@solar whale It is a 5V device
does a M0 expect 5V?
and I have the pullup-resistors connected to 3.3V
solar whale
The M0 is also 3.3 V so I don;t know but I would be careful connecting a 5V device to either one. I'll defer to someone with more harware experience to comment. Good luck -- I see you also posted your question to the forum so I hope you get some help soon.
light plaza
Hm, but Adafruit is selling them (the Version without HP, that is 5V, too ) and they have a project (range finder), where they have wired it the same way as I do (even without pullups, but I have tried it without pullups, getting the same exceptions). And Adafruit is providing this lib.
It would IMHO make no sense, if they would sell hardware, provide a tutorial together with a lib, if it would not work from a power point of view, would it?
@solar whale and thank you for your comments
solar whale
@light plaza I don't work for Adafruit - I was just trying to help and as noted I don't see any obvious problem. Hopefully the people who provided the library can respond when they are online. Good luck!

@tulip sleet yes, I already did, but there was no answer, so I had a look into the chat, if here is a better place to ask ... I am not that familiar with the many "channels" Adafruit offers to communicate to its customers ....
tulip sleet
@timber mango Could you give a link to your forum post? It can take a few days for a specialized response some time. Also, if you think there's a bug in the library, post an issue in its github repo. Discord is for more casual support and support by the community. Only a few of the support people monitor Discord

@tulip sleet Ah ok, here is the link to my forum-post: https://forums.adafruit.com/viewtopic.php?f=60&t=145569

@timber mango - it appears there are differences in the I2C details: http://blog.pistuffing.co.uk/garmin-lidar-lite-v3-vs-v3hp/
light plaza
@tulip sleet ok, thank you, so the lib has to be adapted to the new registers? that leads to my seconfd question on the forum, How to do that 😉
and what I do not understand in this case: Why is it possible, to use the same version of the official Garmin lib for both LIDARs and why do they not mention on their github page, that there are differnces .... but, I will have a deeper look at these registers, to compare them.
I actually did a quick comparison, but there it seems, that the registers are the same .... so I have to look more accurate .....
tulip sleet
@timber mango i think the regs are the same but the way they work is slightly different (based on that blog post above). The Garmin Arduino library probably handles both, but we don't (since we don't sell the V3HP and so didn't test against it).
there may be other clues in the vast internet, but that was the most promsiing link I found
umbral dagger
@light plaza I replied to the forum post. As for the issue of 5 vs 3.3. It just worked when I hooked it up. I had an I2C level convertor on hand in case it was needed, but it didn't seem to be. I never encountered any issue during coding, build, & testing.
@light plaza There's (in garmin/LIDARLite_Arduino_Library) actually separate libraries and examples for each model.

Apparently I'm going to need to trace execution to see where cycles are going. assignment of a single value (foo[n]) vs slicing is significantly slower than expected - worse than neopixel.py even. Except in one code path. Either way, I'd like to know why.

Does anyone out here have experience with the mcp9808 temperature breakout board?
idle owl
@raven canopy Or depending on when the meeting ends, maybe today, but probably not.
tulip sleet
@timber mango i would hope the data sheets show the differences (not necessarily explicitly). As @umbral dagger mentioned in the forum, it sounds like the Garmin-supplied drivers cover both V3 and V3HP, so that could could be taken as "truth". @umbral dagger said there are different versions for the two variants (? I haven't looked at the Garmin library)

Finally getting back into the serial comm issues - holidays took me out.
light plaza
@tulip sleet ok, after looking into the zip file, I saw, that there are indeed two versions, one is called LIDARLite and one is called LIDARLitev3HP ... so - as you said - inside of them must be the truth 😉
tough flax
@tulip sleet I've added debugging at the Python level - basically its never returning from input() when the string is sent from the command line (via echo)
From minicom it does... that will push me to look at how we're calling the readline lib...
umbral dagger
@light plaza Between the Garmin libs and datasheets, it should be easy to create a 3HP module.

carmine kestrel
greetings
i have a question
i want to have the itsy bitsy m0 provide a raw bytestream over usb since i need a fairly high bitrate for something
500+ kb/s
upbeat plover
i think USB is limited to 115200?
raven canopy
@carmine kestrel i can't give any concrete yes/no on possibilities; my understanding isn't strong enough to be definitive. however, here are some things to consider. the M0/M4 are USB Full Speed compliant, which means theoretically the bitrate is 12Mbps; practical speed is much less (1-9Mbps based on googling, with most results in the lower range).
if you are using CircuitPython, i don't recall a method to send a data stream through USB; only to capture receiving it using input(). (someone please correct me if i'm wrong on this.) the only real option is to use an external UART-to-USB converter, and use busio.UART. there is also USB HID support, but that would most likely be quite limiting since you'd have to convert data to keycodes/etc and parse it on the PC side.
Arduino may have better options, with the use of Serial \ Serial1. i haven't really used Arduino in quite some time, so i can't help at all on that front.
carmine kestrel
i was hoping since it had the HID capability i could pretend to be some other USB device
modem ? or perhaps audio or so on
to the stream the data that way
long as i can open the raw stream PC side before a decode
raven canopy
well, there is HID Consumer Control. but, if you were planning that, then i guess you already thought about intercepting and parsing on the PC side.
carmine kestrel
i should then be able to implement a custom decoder to pull out my data
timber birch
Humble has a new python bundle out.. I posted the link in books
carmine kestrel
HID doesn't seem the right overall choice though since it's ISR driven handling in the OS with limited to 0 buffering
there is already uart over the usb but i'd need it to run @ 1 Mb/s ish and i don't know if it will let me
raven canopy
yeah, i agree. iirc there is an open issue for (re)implementing multi-terminal, but not completely sure that would allow this. and, i'm fairly certain there hasn't been any movement on it.
carmine kestrel
best idea was to present as an microphone
and then open that
and then take the bytestream and re-interpret
BUT i'd have to know how to present as a microphone vs HID
raven canopy
@tulip sleet did most (all?) of the HID work. he would know best if that can be extended.
carmine kestrel
ok
technically it's 5 microphones but i can interlace them in one stream so no big deal
TY though 😃

pliant pond
Thanks for answering! I was just hoping for some of the encoding to be offloaded to smarter brains than mine 😄
inland tusk
@prime flower Brent hope you have one too
tough flax
@tulip sleet @tidal kiln I have an update - basically two things have to be true to get input() to return and provide data (at least when the client's linux). 1) You must send a carriage return (\r) - Minicom does this and echo does not. and 2) you must read from the socket (from the linux side).
So, the following works:
$ printf "red\r" > /dev/ttyACM0
$ cat /dev/ttyACM0
The only problem I've found is that cat never returns (neither does tail which I found surprising). I also learned that there's basically no way to make echo send a \r consistently, but the bash builtin printf does fine.
This command works exactly as I'd like :
printf "@wheel\r" > /dev/ttyACM0 ; head -1 /dev/ttyACM0 > /dev/null
Still would love to know why I have to read the stream to get it to act, but I'm not complaining - I have a solution 😃

@terse bay moving over from #help-with-projects, what OS are you on and which version of CircuitPython are you running?
terse bay
Alrighty, this looks like the proper forum for my question:
I am fairly versed in MATLAB and ARDUINO coding, but have taken on the side project of learning CIRCUITPYTHON by building a neotrellis toy. I have a Feather M0 Exprtess built and functioning and am currently working on the code for a Simon-like sequential memory game. I am building it off of the simple Neotrellis Example file. My question is this: How do I edit and save .mpy files? I am using MU as my editor and it doesn't seem compatable. Ive searched quite a bit to no avail. THANKS!!!!!
im on windows 10, CP version 3.x.x
im at the gym on the treadmill lol, if you need the actual version I can post in a bit when I gewt home
light plaza
@terse bay as far as I have understood this, you cannot edit the *.mpy files
raven canopy
Actually, let me back up a minute.
How do i edit and save .mpy files?
.mpy files cannot be edited. they are .py files that have been converted to bytecode, using the mpy-cross utility. so, you'll have to edit any .py files, then run mpy-cross to convert them. here is a link to download mpy-cross 3.x for windows: https://github.com/adafruit/circuitpython/releases/download/3.1.1/mpy-cross-3.x-windows.exe
light plaza
you have to edit *.py files and use a "cross-compiler", to "compile" *.mpy out of them
raven canopy
@terse bay are you trying to edit a library/etc that was downloaded, or your own local files?
terse bay
oh ok, that's silly, but I think I understand. So in order to get into Imported files from an example code, and tinker with them ( that seems to be how I learn best what things do), I need to pull it off the GitHub, save it as a .py file and put that in the lib folder on board, then I can edit it? must I also delete the original .mpy that im tinkering with?
can I import .py files exactly the same way as I have been with .mpy files?
raven canopy
@terse bay you can download the .py bundle, as opposed to one-at-a-time.
and yes, .py imports the same. however, memory issues can arise depending on the size of the file. CircuitPython does the bytecode conversion of .py files internally, but that takes up additional RAM space. that is why using .mpy is recommended (required in some cases).
upbeat plover
@raven canopy https://cdn.discordapp.com/attachments/327298996332658690/529493911924768778/express.py is line 109 needed?

@raven canopy Ya i have the current pi bundle for version 3.x.x . and sounds good, thanks. I suppose I will go ahead and learn how to use mpy cross, I guess it will be handy eventually .
raven canopy
@upbeat plover its possible that the instance variable could be removed, and have the property just return the math.sqrt result. i don't see anywhere else that the instance variable is used...
upbeat plover

return temp
while not i2c.try_lock():

# Then make again.
for updating but i usually just delete the whole circuitpython and git clone
if i have changes i keep them backed up somewhere else
acoustic pollen
is there a way to re-install the library just with a folder or is it unique to every cpx board?
upbeat plover
if your trying to change frozen lib adafruit_circuitplayground.express library you have to rebuild and then use new uf2 file
im not sure how its "missing"
raven canopy
@acoustic pollen the library is "frozen into" the CPX firmware. if importing it is failing, then the file system may be corrupt.
idle owl
@upbeat plover I replied to your PR on GitHub. Unfortunately we won't be able to add the feature to the library. It's already almost too big. The buffer required to do sound sensing causes memory allocation failures consistently as soon as any other code is added to a program. It runs fine alone, but if you add any other features to your program, it begins to fail.
We tried before, I have the code already written to add it. 😃 But until there's an update to how memory is handled or physically to the CPX, it isn't viable.
acoustic pollen
for some reason the keyboard feature isnt working on circuitpython on the cpx
from the make it a keyboard guide
upbeat plover
@idle owl can i get an example of a failer? cause im not seeing any issues yet and only diffrence is 176 bytes when importing cpx
I believe you i just would like to understand it.
idle owl
@upbeat plover I can in a bit. It was failing when you started to add other things like NeoPixel or light sensor or some other feature of the lib. Like, if loud_sound() (which was simply a threshold check), turn on NeoPixels or something like that.

I'm not that great at neopixel demos haha, and I'm not sure if my library is even stable enough to do anything more than that
idle owl
@upbeat plover I appreciate your enthusiasm! The problem is that memory usage isn't always consistent, so even with gc.collect() included in express.py, we're still opening things up to potential failures. Like I said, the library is already massive. The amount of space left over after import is less than we'd like to have already. sound_level() requires a buffer. The difference between what I have written and what you wrote is that your buffer is half the size of mine - mine was 160 bytes which is what was used in the Sound Meter demo. It's possible that you're running into less issues than I did due to that difference.
but even losing 80 bytes to the buffer for your magnitude is not ideal.
I'm willing to test what you come up with, but I'm really not sure it's viable with the current environment.
upbeat plover
alright, im still gana give it a shot cause CPX "the clapper" is nice
idle owl
If we decide to include it, we can reopen your PR and make changes there (there are a few things that would have to change for backwards compatibility and to fit with the library design)
I agree! That's why I tried to add it. I like the idea of having as much of the functionality on the board in that library as possible.
The last two things are sound and IR. Both are massive unfortunately.
upbeat plover
yeah IR need much bigger buf

marble hornet
okay,... it should be these:
https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython
regal juniper
Yes, I have installed these too.
marble hornet
i'm thinking...
can you try installing once more, just incase (i had to only check the top line to get them to work on win8 )
stuck elbow
since bootloader appears, the cable is not power-only
marble hornet
so it's probs sw thing right? (on one side or another)
regal juniper
I don't get it.
marble hornet
becasue the bootloader shows up that means there is a data connection. that means the problem isn;t in connecting to teh board it is software problem
did cp work before the update?
(please excuse the spelling)
regal juniper
The thing is I have had developed a custom board with some other modules on it along with Itsy bitsy controller. While designing I followed the schematics of Itsy Bitsy controller. When the board arrived, I burned the bootloader using Jlink and now trying to install cp but coming up with the issue.
Cp never worked.
marble hornet
so it isn't a from adafruit board? but the same pinout ?
is there a flash chip on the board?
marble hornet
is there a GD25Q16C on the board?
and i'm just curious are those 0402?? really cool!
regal juniper
yes these are 0402, I doubt the existance of GD25Q16C
marble hornet
ah okay, so the itsy m4 board has that built in. it is where the files are stored
@stuck elbow is there enough space for an m4 with internal flash as the drive?
regal juniper
3.87 MB
marble hornet
where do you see that?
regal juniper
The drive with label ITSYM4Boot.
marble hornet
i see that on my m4 board too, but that doesn;t necessarily mean that there is 3.xx mb of flash
i think, if you don'y have external flash connected to the atsam51, you will need to make a custom board file for your device which uses the internal flash as the drive
regal juniper
The reason I am trying for cp is that I want to configure sercomm ports as serial ports. Is there any way around? Can I do it using Arduino IDE?
marble hornet
i don;t have the expertise but plenty of the cp helpers can help with the board configuration. (it isn't too complicated) i've done it, just not enough to show someone how
and i'd ask in #help-with-projects about that in arduino
marble hornet
are you familiar with github?
manic glacierBOT
marble hornet
i do know it isn't that difficult you just need to know what to do, i suggest askig someone with more experience then i.
regal juniper
Yes I am.
marble hornet
okay, so you'll need to clone the cp repo then in ./ports/atmel-samd/boards duplicate and rename the itsy m4 folder then the changes will be made in there
regal juniper
Thank you.

@solar whale did you use a jlink to flash the particle with ?
or is there another way to get circuitpython loaded on there, like the uf2x sketch
solar whale
@prime flower yes -- flash bootlader,sd then CP
jlink only for bootlader and SD -- uf2 for CP
manic glacierBOT
solar whale
I think you need to put our bootloader on it first -- needs J-Link
solar whale
@prime flower here is what I did - using J-Link -- cloned the nrf bootlader https://github.com/adafruit/Adafruit_nRF52_Bootloader, then ```in projects/adafruit_github/Adafruit_nRF_Bootloader
make BOARD=particle_argon clean
make BOARD=particle_argon
make BOARD=particle_argon erase
make BOARD=particle_argon sd
make BOARD=particle_argon flash
copy CP .uf2 to CIRCUITPY
same for particle_xenon
@prime flower I am not familiar with what you refer to as the uf2x sketch -- I don't know if a stock particle board can be uploaded to by arduino or not -- iI have not tried that.
prime flower
was referring to https://github.com/adafruit/uf2-samdx1, but I'm following along with the nrf52 bootloader rn
solar whale
@prime flower try this link https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF5-Command-Line-Tools
prime flower
yep that works, adding to my path
solar whale
@prime flower let me know if it works OK -- I have not upgraded to the latest nrfprog so will wait until you confirm before I do 😉
solar whale
@prime flower Nice! I don't think Mu is particle aware yet --- not sure how to get it there...
prime flower
fairly quick flash -> install, but I had the arm toolchain already installed
solar whale
yeah -- it was quick and easy for me.
prime flower
Download the ESP32 firmware bundle above, unzip and place the esp folder in the root directory of your CIRCUITPY drive alongside adafruit_miniesptool.py
@solar whale do you mean, keep miniesptool in CIRCUITPY instead of lib/
oh you didnt write that part, whoops
solar whale
oops -- missed that -- if you have miniesptool in the lib, then no need to copy it over again
