I know that there is input() for the serial console, but is there anything similar to uart.read() for the console (something that is non-blocking)?
tulip sleet
@fathom lava We have sort of a workaround. You can use runtime.serial_bytes_available to find out if the user has typed something. If so, you can call input(). https://circuitpython.readthedocs.io/en/3.x/shared-bindings/supervisor/Runtime.html?highlight=available#supervisor.Runtime.runtime.serial_bytes_available
fathom lava
@tulip sleet Sweet, thank you!
tulip sleet
this has been painful. There is really nothing in Python for this that is OS-independent. The Python solutions are all kind of awful.

@solar whale if you are playing around with it and find a fix, latest is here. https://github.com/adafruit/Adafruit_CircuitPython_TinyLoRa/pull/4
I tested it but my gateway is finicky today for some reason, might be my internet. I'll try it at HQ tomorrow to see if that helps it
sacred edge
in Neopixels, is there a default brightness?
sacred edge
@tidal kiln - I am writing a .py file to read a signal from a PIR, and then have it kick on the neopixels... Either on the CPX or perhaps a "Jewel" neopixel board... Developing the code right now...
The PIR is giving me fits... It works fine, BUT I am unsure if I am looking for a voltage (Analog) or Digital "High" signal. The PIR puts out 3.3vdc when it is activated ..
being a total newbie to this coding stuff sucks!!!\
tidal kiln
this PIR sensor?
https://www.adafruit.com/product/189
sacred edge
Not that exact one, but very close.. from DIY mall - http://www.diymalls.com/index.php?route=product/search&search=DIYmall HC-SR501 PIR Infared Sensor Pyroelectric Motion Sensor Detector Module (pack of 5pcs) FZ0057X5
it goes to 3.3vdc when activated, and 0vdc when not triggered...
tidal kiln
sounds similar and digital:
https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/circuitpython-code
sacred edge
does the cpx have a built in PIR??
@tidal kiln that code you gave me without my external PIR hooked up, I get motion detection...
it seems that the neopixel #1 is detecting the motion!
weird!
tidal kiln
@sacred edge how is the PIR sensor connected to the CPX?
sacred edge
I have it hooked up to A2, But when I have my hand over the CPX board (Neopixel 1) it trips motion detection and not from my external PIR sensor...
what is pin D2 on the CPX?
tidal kiln
A5
just change the code
A2 is D9
you basically had a floating input and were reading noise
sacred edge
seems to have fixed it.. the floating ground was weird.. lol... it won't detect my hand moving, but does detect the body...
tidal kiln
if your PIR has those two trim pots, may need to adjust those
sacred edge
yes, I am fiddling with them now..
sacred edge
I have it working pretty good now.. Thanks!!.. now to incorporate into something that makes sense... 😃

@slender iron travis builds are stalling for some reason. A single board is taking > 10 minutes and that causes the travis job to terminate because there's no output for >10 minutes. I tried the latest merge locally and there's no issue so I'm inclined to think travis is flaking out right now.

Status is showing all green. Wonder if it's today's "all Linux will run in VM" switchover.
Even though that shouldn't affect our builds since it's already in a VM, and not a container.

I'm running "full" Python on a Raspberry Pi and trying to connect the Adafruit SGP30 gas sensor breakout. I have it working with some weird 3rd party library, but I want to use the Adafruit version. I see there's a CircuitPython version, is there any issue with me using that on a traditional Python/Linux computer?
raven canopy
@timber mango there is! It's called Blinka: https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/overview
timber mango
That's what I was afraid of, this is the last component on my build and everything is written in Python 2.7 😦

@tulip sleet hi! I'm attempting a cpy build w/the NRF9x M0 Feather and the tinylora lib. I followed the steps in the learn guide for incl'ding the module, added it to /frozen and the build errored. Any ideas?
-none-eabi/7.3.1/../../../../arm-none-eabi/bin/ld: build-feather_m0_rfm9x/firmware.elf section `.text' will not fit in region `FLASH' /usr/local/Caskroom/gcc-arm-embedded/7-2018-q2-update/gcc-arm-none-eabi-7-2018-q2-update/bin/../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/bin/ld: region `FLASH' overflowed by 4412 bytes collect2: error: ld returned 1 exit status make: *** [build-feather_m0_rfm9x/firmware.elf] Error 1
tulip sleet
yes, it's just too big. The non-Express builds are very tight, and there's no room for a frozen module
you'd have to remove something else to get it to fit
prime flower
alright
tulip sleet
do you want to freeze iti because the lib is so big that most programs that need it won't fit?
it may make more sense to use a Feather M4 and an RFM wing
prime flower
Yep. The MPY file(s) required for it take up a lot of room, ladyada had a lot of tweaks last night for space but it's still too large for the library and a sensor library (or even busdevice's i2c)
tulip sleet
there isn't much to remove to get it to fit. on the pirkey we removed math, which is big, but the pirkey is a very special-purpose gadget
prime flower
this'll need math for AES, could just be a m4-only library but idk if that's a good solution. Maybe for the short-term it is.
tulip sleet
prob worth discussing with limor
prime flower
yeah, agreed.
tulip sleet
math is mostly floating point stuff, sin, cos, etc. not sure you need any of that for AES
But... some sensors might need math
prime flower
especially if it's being used as a data-logger (which most radio-feathers are)
solar whale
@prime flower have you tried just loading the lib from . mpy files in the stock build. That does work on a mo express.
prime flower

@slender iron ugh, looks like it's hanging again: https://travis-ci.org/adafruit/circuitpython/jobs/463954390. This is like before: the PR check build was fine. So the q is what's the diff between the PR build and the merge build??
slender iron
git revision stuff?
tulip sleet
maybe - I'll try setting a local tag so it looks like a something. Or are there diffs in .travis.yml between deploy and not?
slender iron
maybe we can repro on a branch?
rather than a pr
it probably has to do with the travis environment variables
tulip sleet
that might get checked in on of the .py scripts
slender iron
can probably repro it off master by making a new branch and PRing to it
then its easy to add debug statements
tulip sleet
or I can just push a branch that's instrumented
will it build automatically if I just push a branch?
tulip sleet
I'll try a branch first
raven canopy
ears perk up
slender iron
just like the bootloader but slower
so before boot.py runs have a small window where if it resets we can tell
and after the reset enter safe mode
tulip sleet
that is a great idea. Could light the RGB to indicate in that state. maybe 0.5 seconds. I already delay 1.5 seconds when writing boot_out.txt to handle a weak battery: line 324 in main.c
slender iron
haha, we could just overlap those two
tulip sleet
usually don't need to write boot_out.txt because the version hasn't changed, so a 1.5 second startup delay is a little much, but could make it at least 0.5 seconds and 1.5 seconds when updating boot_out.txt
slender iron
kk
I don't think startup time doesn't matter too much because it doesn't impact reloads
I'll add that window and reduce the boot out pause accordingly
solar whale
@prime flower yes, that works -- using the default build for the feather_m0_rfm9x and copyin adafruit_tinylora(with .mpy's) adafruit_busdevice and tinylora_simpletest.py -- it runs!
and the file system is only 43% full...

@slender iron there wasn't anything wrong with the builds, it was just that it the output was all buffered and the buffer was big enough to hold >10 mins worth of builds. I fixed with print(flush=True) inside build_release_files.py. We could also fix by invoking it with python -u build_release_files.py (-u is unbuffered). Trying to think if we should do both.
@tidal kiln I can add a pointer to the forum post - pretty specific fix

@solar whale I'm trying the original bleio merge, which is before the tinyusb merge. Original bleio does advertise (I can see it on a phone app), but the current HEAD seems to crash on advertise(). Have you seen anything different or have a workaround? Otherwise I'll start debugging the problem.

do you have a sample code to run?

first part of this: https://github.com/adafruit/circuitpython/pull/1289
import bleio
periph = bleio.Device()
serv = bleio.Service(bleio.UUID(0x180f))
periph.add_service(serv)
chara = bleio.Characteristic(bleio.UUID(0x2919))
chara.read = True
chara.notify = True
serv.add_characteristic(chara)
periph.start_advertising()
this shows up as a battery service on the nRF connect app, though with errors, but it's advertising. This same code was crashing with SPIM3 enabled. In the latest HEAD, it doesn't come back to >>> after start_advertising(). Dunno if you've done more than this in the past.
my own work up to now has been changing the api but not the underlying impl, so I just want to make sure I was starting with something that was working, which it isn't 😦
solar whale
the one I used with ublepy was much simpler but I never converted it to bleio -- I only tried scanning.
tulip sleet
ubluepy assumes it's a central; I don't even think it acts as a peripheral right now
solar whale
its not even there
tulip sleet
just checking; I thought you had submitted an issue about bleio not working, but I can't find it
right ubluepy is from bluepy which assumed it was a host

it'll be a few more minutes befeor I can test it

well , it worked for awhile -- then it died
it died after I did a soft reboot -- let me see if that is repeatable
it has been running for a few minutes...I was able to mount SDCard with it running
so it appears to be related to the reboot - noramlly it keeps advertising through a reboot.
still running after soft reboot
but I have not rereun the script to start it

it was running fine untill I reran the script to start it.

@solar whale that's very interesting; something we're not resetting on reload; I think I may have done the same thing just because of a typo or soemthing
solar whale
it is strange becasue I still sseing the UUID 180f even though I don't set it -- even after power cycle
and if I read periph.name after creating it -- it says "CIRCUITPY" is taht set by default?
I recall some issues in the past about starting advertising if it was not stopped. But it threw an error -- not crash
ok -- I can change the name -- have to stop/start advertising for it to be seen
sending a second start_advertising() does not seem to hut anything -- I think I got errors for that with ubluepy
there is some strage stuff with the way some of the apps "remember" the peripherals and it gets very confusing...
hmm after severla stop/start cycles I fninally got this ```>>> periph.start_advertising()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: Failed to start advertisment, status: 0x00000012

periph.start_advertising()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: Failed to start advertisment, status: 0x00000012
@solar whale, yes, the reset logic on restart is missing from a number of the peripherals. I just fixed UART pin allocation but there's lots more to do.

@prime flower should there be a warning in the examples that on a Raspberry Pi you need to install an LED or comment out the code? I guess it should be obvious to the user...

I don't have access to the repo, mikeb made it.
prime flower
ah ok
idle owl
Under settings there is a tab for Maintainers. Please add kattni and adabot.
prime flower
added!
idle owl
Thank you
Ok, first, the name is incorrect. It should be Adafruit CircuitPython TinyLoRa. That can cause issues with the URL generation everywhere else I believe.
Second, did you add it as a subproject to CircuitPython?
That's what causes it to have the URL generated by cookiecutter.
There's a process to getting RTD setup, it's not just a matter of adding it to RTD.
prime flower
I was following this -> https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/sharing-our-docs-on-readthedocs
idle owl
That needs to be updated apparently.
I don't think you have access to do the entire process.
Please fix the name and I will try to finish the process.
idle owl
That's not how to do it.
You have to go through the CircuitPython project itself.
The badge still says "unknown" which sometimes takes a bit to update, but if you go the TinyLoRa repo, you can click on the Docs badge currently and it takes you to the docs now.
The project slug and short URLs are still wonky from the incorrect naming, but the CP URL works now, and that's the one that gets linked everywhere. so I guess it's fine. I don't see a way to change the other things. Maybe they will update eventually because we changed the name.
prime flower
yep, links properly from the repo on my end too
idle owl
Ready for me to merge then?
prime flower
Yep
Would I (or someone reading that guide) be able to add it as a subproject to the circuitpython project?
idle owl
Not in general no. I believe you need to be added as a maintainer.
I updated the guide to reflect the naming thing.
prime flower
thanks. i was confused why it wasn't building the url properly

HI
About translation, some french string need to be updated.
Is it better to open a new issue ? or re-open https://github.com/adafruit/circuitpython/issues/1113
?
idle owl
Open a new issue, @timber mango
But for your own knowledge, either way would have been fine. But you can always feel free to open a new issue.
timber mango
OK, thank you 😃

@unique maple it's impossible to predict when it'll be ready until it is. There are too many unknowns to know what work is left to do.
tulip sleet
@unique maple I am trying to get a vertical slice working, say, making sure the Nordic UART service works. But there are all kinds of "interesting" bugs that have or will crop up.
So no timeline, but I'm working on it on a daily basis.

@tulip sleet are your flash erasers written in arduino?
tulip sleet
@tidal kiln yes, but I didn’t write them. They’re in the SPI Flash library in a sub directory

EDIT: No clue, magically works now

I am not sure what the right way to ask this question since I don't have a real understanding of Circuit Python or of the Particle boards: I would like to find out the state of Circuit Python on Particle Argon and Xenon boards. My understanding is that loading Circuit Python on one of those boards, wipes out the Particle bootloader and all. As a result it will have no Particle feature support. Is this just an interim issue or are there plans to have Particle mesh support while using Circuit Python?
slender iron
@bitter bronze correct we replace everything. we don't have plans to interface with the existing bootloader. I'd like it if someone added it though
@ruby lake @tulip sleet how would you cache incoming midi commands from usb?
I could do a merged circular buffer or unpack the midi bytes and have buffers for each virtual cable
bitter bronze
@slender iron Thanks. I certainly don't have the skill to that. Excuse my ignorance but if all the mesh stuff is thrown out, what is the advantage of running CIrcuit Python on those boards?
slender iron
its an nrf feather 😃 better for development
bitter bronze
Another question out of ignorance - why is nrf feather better and isn't Adafruit developing a nrf feather?
slender iron
@bitter bronze we are, its just not out yet. by supporting the particle then folks with that hardware can use circuitpython too
bitter bronze
So is there anyway to couple the coming Adafruit nrf board (or other Adafruit boards) with a Particle mesh network?
slender iron
not yet but the mesh protocol is open so it should be doable
bitter bronze
Thanks.

Help! Just unboxed Adabox 010. Updated the bootloader as instructed. Now the device won't load out of bootloader mode.
tulip sleet
@slender iron @ruby lake would have better intuition on this, but maybe you could do it like PulseIn. Not sure it's all that different from a UART buffer or anything else like that. The question is how big a buffer you need and @ruby lake would have intuition on that.
ruby lake

@slender iron I use a ring buffer size 128
I also use a smaller ring buffer size 32 for some things

Can I use SDA and SCL on an Itsy Bitsy M4 as uart? I seem to be getting random garbage over the line, but was working fine on TX and RX.
exotic pumice
let me look up the pads
I'm pretty sure that would work, which is TX and which is RX depends on which sercom the uart library chooses to route things through
idle owl
@bronze shadow https://learn.adafruit.com/circuitpython-essentials/circuitpython-uart-serial#wheres-my-uart-13-14
Might help.
exotic pumice
Interestingly those pads are on sercom2 and on sercom4
meager fog
@ruby lake lol
@last drum can you get to the CIRCUITPY drive at all?
@tulip sleet all neotrelli come locked now, so i removed the bootloader page
exotic pumice
and I believe UART relies on TX being pad 0 or pad 2, while RX is any other pad. SDA is Sercom2 pad 0 Sercom4 pad 1, and SCL is Sercom4 pad 0, sercom2 pad 1
bronze shadow
So the TLDR is that I can't. Darn.
exotic pumice
no it's not
bronze shadow
Sorry, really nat a hardware guy. Trying to piece that all together and obviously have a lot of reading to do.
meager fog
m4 is very weird, its pickier on sercoms
if circuitpy lets you make the object, the pins will 'work'
bronze shadow
Hmmm. I'll keep seeing why I'm getting random garbage then. Everything else is basically identical to when I had it to TX and RX on the boards, and all new connections multimeter as a good connection.
bronze shadow
I've gone through it all now. I have to order some new PCB's and remap the pins elsewhere.
last drum
@meager fog I can't get to the CIRCUITPY at all. That's why I am asking for help.
meager fog
@last drum if you double click or click, do you see any disk drive at all
or the LED on the back pulsing
check also the device manager - you should have gotten a serial port if its in 'arduino' mode
its normal for the drive to go away, you have to re-install circuitpy
tulip sleet
@last drum When you uploaded the bootloader update, that wrote over CircuitPython, so you have to reinstall it

it handles endianness and signed/unsigned
yah
np, i didnt know about it at first either. theres a lot of 'tricks'
solar whale
@tulip sleet just a thought -- tha last time I flashed the sd to my pca10059 I thin k it was 5.0 but the current builds are for 6.1 -- do I need to reload the SD on the pca10059?
tulip sleet
we're assuming 6.1, not sure what would not work with 5.0
solar whale
thats waht I was wondering about the isuues we are having -- or maybe it is 6.1 -- is there a way to check?
I did a quick ble advertise with the particle_xenon -- worked -- did not try resetting it.
I can just reflash it to be sure -- but I think it does not work at all if they are mismatched.
solar whale
@tulip sleet does it make sense taht the pca10059 keep advertising even after a power cycle?
tulip sleet
that's amazing, not sure why.
is it really advertising or is it just the app that says it is? Suppose you leave it unplugged 😃
solar whale
wheew! that was it -- my head hurts 😉
if I kill the app and restart, it goes away ...
tulip sleet
BLE ghost mode
meager fog
oh yeah BLE caches like heck
makes advert name debugging hard
turn it off/on in ios to clear
solar whale
yes -- it gets very confusing!
@tulip sleet ok -- just reprduced the issue from last night on the pca10059 with SD 6.1 confirmed. Now to try it on the xenon
tulip sleet
it's all about the soft restart - we don't restart the nrf softdevice - i'm talking with thach about how to do that cleanly, or do something similar
solar whale
so far, the xenon is not crashing after soft reboots and restarting the advertising....
tulip sleet
scott pointed out we may want to maintain or re-establish the basic BLE connection info across restarts to maintain REPL and other BLE-based stuff, like say tablet file editing.
but not the user-program BLE stuff
e.g. right now USB stays up, but all the pins get reset
solar whale
I'v done a few cycles. - have not killed the xenon yet
ah -- I was running my very minimad adv -- yours does kill it 😉 with adding the characteristics.
so it sounds like this is not an unexpected problem and I should not expect it to work. I'll move on to other things.
tulip sleet
yes, that info doesn't get cleared; right - it's a known bug
solar whale
still -- it's great to be able to start playing with it -- now on the dongle and the xenon.

is there any documentation, how to use wifi on Feather Huzza running CircuitPython
for example running a webserver on the feather Huzzah, to remote controll it over wifi
raven canopy
@marble hornet PRs are based on a branch's commit tree. so I would just make a branch, commit and push your changes for that file/folder to that branch, and then submit the PR from the branch.
marble hornet
okay, i think i should describe better, i branched and paired down some of my code in certain files and folders, in other folders i made an improvement. i want to take the impprovments in the paired down 1.x branch and bring them to master
so, ooooooooooohhhh
i think i get it, maybe
marble hornet
no i don't, so the changesare committed to 1.x. should i make a branch of 1.x or master to then pr?
raven canopy
If you've already made the changes in branch 1.x, you should be able to PR from that branch. On GitHub, if you click the compare button, you can review what changes will be included in a PR. You can also change which remote/branch the PR will point to and see the changes against that.
tulip sleet
@last drum Thanks. We ended up deleting the section because the Trellis boards shipping now have a protected bootloader. Only the first few batch had unprotected bootloaders - osrry for the trouble!
solar whale
Ran a few I2C sensors (tmp007 and vl53l0x) on the particle_xenon with CP -- no problems -- pretty slick!
the pca10059 has been fun, but this "feather" compatible with 4 Mbyte Flash is really nice
solar whale
it really is "feather compatible -- hooked up a RFM9x featherwing and it is transmitting!!
raven canopy
@solar whale @slender iron I've been think about the Particle Cloud interaction. The good news is, that it's just a RESTful protocol, so a wrapper/module is easy. The "barrier" however is having a socket available. I'm hoping to jump back into core work soon, so hopefully I can help run that to ground.
solar whale
At this point I can't use the xenon on the "mesh" because it does not work with some Xfinity routers. So CP is a huge improvement 😉 I'll be happy to help get it into the "mesh" but it s a great, inexpesive nrf52840 board!
If we put CP on and ARGON board, I assume it will just ignore esp32 -- Functionlally, it will be the same as the xenon, correct. Is there any way to commincate with the ESP32? I guess I have a lot of reading to do...
raven canopy
I haven't looked at the build yet, but I would assume that's correct; esp is ignored. I'm not even sure how the Argon communicates with it. AT protocol maybe?
solar whale
magic 😉
I'm decalring victory for the morning -- off fora bit -- then more fun later
raven canopy
@solar whale quick look at the Argon source, looks like AT over Serial. Could be easier than we expect... https://github.com/particle-iot/firmware/blob/cdf25a93f9b6283a0907e2fa5afe259d56dd6594/hal/src/argon/network/esp32_ncp_client.cpp#L21

@prime flower Nice job on the TinyLora Guide!
idle owl
@tidal kiln Ok, I think I have time for now. Are you available?
tidal kiln
sure
idle owl
Right on. Where/how shall we discuss it?
tidal kiln
hmmmm. hawaii?
idle owl
I'm in
tidal kiln
let's just dm, it's just housekeeping work. not really of interest here.
idle owl
Ok sounds good
solar whale
@idle owl Is there a guide or some examples for recording audio (from the mic) on an M4 -- like the neotrellis_m4.
idle owl
@solar whale I have no idea. I asked though, I'll let you know if I find out anything. Do you mean with CircuitPython?
solar whale
yes - CP -- just curious -- no rush
the board show MIC_IN and MIC_OUT so thats a start 😉
idle owl
We have sound recording code somewhere, tried using it on CPX but the buffer had to be so tiny, it could record a couple of clicks and that's about it.
Like this: python mic = audiobusio.PDMIn(board.MICROPHONE_CLOCK, board.MICROPHONE_DATA, frequency=16000, bit_depth=16) samples = array.array('H', [0] * 160) mic.record(samples, len(samples))
For CPX there.
No idea what it would be for a mic plugged in to the NeoTrellis though
solar whale
yeah but that is an I2S mic -- is the M4 the same?
idle owl
No you plug one into the audio jack I thought
I don't think there's one built in
Like mobile phone headphones work
solar whale
right and it has an amplifier so its an analog input, I think.
idle owl
Yah I'm not sure. I'll let you know what I find out though. Worth knowing 😃
solar whale
Thanks -- I just wanted to make sure I had not missed something I should have known about.
idle owl
No problem
solar whale
looks like Arduino supports it... https://github.com/adafruit/Adafruit_NeoTrellisM4/blob/master/examples/trellis_talkthrough/trellis_talkthrough.ino
idle owl
@solar whale That's why I asked whether you meant CP specifically. There's an example for Arduino in one of the step sequencers.
solar whale
Yeah -- I remember trying it when I first got my neotrellis -- was really looking for CP but nice to know the HW works -- now " it's only software"
solar whale
I'll bet he has a long "short list" --thanks -- I'll be patient....
solar whale
@raven canopy the "interfaces" block diagram in this datasheet shows the pins used for the URAT between the nrf52840 and the ESP32. https://docs.particle.io/assets/pdfs/datasheets/argon-datasheet.pdf -- I have not found a full schematic yet, have you?
raven canopy
@solar whale I haven't seen one, no. But, I haven't tried that hard, either. That block at least confirms serial and which pins, without having to dig through the source code (which is not fun, imo).
solar whale
and they are even defined for the board !! https://github.com/adafruit/circuitpython/blob/master/ports/nrf/boards/particle_argon/pins.c#L57
should be able to create a UART Device -- Looking at it....
slender iron
@tulip sleet @solar whale its not on my short list
today I want to wrap up the safe mode stuff and release alpha.4
next week I want to finish midi and then I'm off until next year
when I get back I want to make the displayio stuff more complete
I'm trying to finish things I've started
solar whale
oh yeah -- you have something far more important on your short list. no worries from me...
slender iron
thanks for the review @tulip sleet !
slender iron
Ok, to accelerate us getting to beta I've shuffled some issues around. Only 5 needed for Beta: https://github.com/adafruit/circuitpython/issues?q=is%3Aopen+is%3Aissue+milestone%3A"4.0+Beta"
solar whale
It would really be nice to fix the Control C issue on the nrf52832 before beta
slender iron
I punted it because our focus should be on the 840
solar whale
OK -- @tulip sleet if you have some time to chat -- maybe you can point me in the right direction to fix it.
tulip sleet
i have no idea really! Have to look at it in more detail.
solar whale
OK -- if it would help - I can tell you where I have looked, but it can wait -- the 52840s are so much more usable with UF2 so perhaps I should just put the 52832 away for awhile
slender iron
Its probably because we don't receive an interrupt on uart receive
therefore we only control-c when we've polled for new input
solar whale
OK -- at least I've been on the right track
slender iron
😃
I'd be happy to see it fixed
we just need to focus on getting 4.0 stable so that we don't need to keep maintaining 3.x
solar whale
I'll keep it on my "short list" 😉
slender iron
then hopefully we can follow up with stable 4.1 and 4.2 to add new stuff but still be stable releases
thanks @solar whale !
solar whale
BTW -- CP is running great on my particle_argon -- trying to talk to the ESP uart....
@raven canopy here is the schematic https://github.com/particle-iot/argon -- getting a bit of gibberish across the UART --- seems like progress -- If I am reading their code right, it uses a baudrate of 921600 (yikes) also uses HE flow control (XTS/RTS) -- for now I just pull CTS low.
slender iron
I found this page useful too: https://docs.particle.io/datasheets/wi-fi/argon-datasheet/
tame hatch
Hi Channel! I'm attempting to read a rotary encoder on a raspberry pi. There's a circuitpython library called rotaryio that seems like it would be perfect, but for the life of me, i can't get it working. Every time I attempt to run the example code, I get "ImportError: no module named 'rotaryio'" I thought this was included in CircuitPython 3 by default, no?
Disclaimer : I have absolutely no idea what version of Circuitpython I'm running! I've attempted, many times, to figure out what version is running, but I have had no luck.
I've also attempted to manually update, but the instructions for doing this are severely lacking on the site...
any help/advice would be greatly appreciated!
tulip sleet
@tame hatch rotaryio is implemented as a native module (in C) in CircuitPython. It's not written in Python, so it won't run on the Rpi. We do have some sample code somewhere that implements rotary encoders in Python. I'll try to find it
tulip sleet
On the RPi, you are not running CircuitPython itself, but are running a wrapper library (adafruit-blinka) that implements the native I/O functions of CircuitPython
tame hatch
@tulip sleet do you think this is a bad approach? My end-goal is to have 4 rotary encoders on a raspberry pi that has a pitft on it as well
tulip sleet
it's not a bad approach, but you'll just need to use some other code to read the encoders on the rpi
we haven't implemented a proxy rotaryio for adafruit-blinka yet; not sure if it's in the works
tame hatch
ok, so something like using rpi.gpio and monitoring each manually maybe?
tulip sleet
yes, I'm having an internal convo right now about this. You'll have to poll; it won't be easy
Some possible libraries there
tame hatch
ok awesome
tulip sleet
there's very often some code or other in github if you search
tame hatch
just as you were writing, I managed to get some code working
using rpi.gpio
now, I need to figure out if I have enough gpio pins to run the 4 encoders and their buttons 😄
thank you very much for helping get my brain pointed in the right direction @tulip sleet

trying 481c4954afd161448aa37d353fa577d409d880c6 it was the last I used - and I think it had the new tinyusb as well, no?
it builds and boots on pca10059
tulip sleet
yes
reversion or latest works on '59?
481c does include the switch back to hathach/tinyusb

this is a bit more encouraging -- the earlier stuff was the ESP32 booting up and transmitting at 115200 baud.. the AT stuff goes at 921600 buad and it looks like we are having some trouble with that, but it does respond ... ```Press any key to enter the REPL. Use CTRL-D to reload.

is there a way to sync PWM pins, I want to run a bunch of LEDs but i dont want them all powered at once. Id like to sync PWM so when one set turns off the other turns on
raven canopy
@solar whale from the ESP32 AT Commands documentation, 115200 should be fine:
The default baud rate of AT command is 115200.
in case you want a quicklink: https://www.espressif.com/sites/default/files/documentation/esp32_at_instruction_set_and_examples_en.pdf
upbeat plover
im aware that they will appear dimmer then if i just ran them all full time
solar whale
hmmm -- I was looking at this https://github.com/particle-iot/firmware/blob/cdf25a93f9b6283a0907e2fa5afe259d56dd6594/hal/src/argon/network/esp32_ncp_client.cpp#L101 at 115200 it does not seem to ork, but it's eary in the process....
@raven canopy thanks
upbeat plover
I'm thinking this will work for Arduino but havent tested it yet, i was wanting a CP solution though
#define P1 3 // Use interrupt/PWM enabled PIN. INT1 in Arduino UNO
#define P2 5 // Any other PIN
#define P1_INT digitalPinToInterrupt(P1) // Converts PIN to Interrupt number. Required only for UNO
// Make P1_INT=P1 for ESP8266
void setup() {
pinMode(P1, OUTPUT); // Declare pin modes
pinMode(P2, OUTPUT);
attachInterrupt(P1_INT, &falling, FALLING); // Attach interrupt on falling edge of P1 and direct to falling()
analogWrite(P1, 125); // Set analogWrite to begin PWM
}
// Runs on falling edge of P1
void falling() {
digitalWrite(P2, HIGH); // Set P2 as HIGH as P1 was falling when this ISR was triggered
attachInterrupt(P1_INT, &rising, RISING); // Reset the P1 interrupt to the rising edge
}
// Runs on rising edge of P1
void rising() {
digitalWrite(P2, LOW); // Turn-off P2 as P1 is rising
attachInterrupt(P1_INT, &falling, FALLING); // Reset interrupt to Falling edge
}
void loop() {
}
@upbeat plover since we don't have ISR available, I think the only way will be to control the pin state with time.
# really rough psuedocode; doesn't implement a full state
# machine or switching code
cycle = time.monotonic()
duration = 1000
while True:
if (time.monotonic() - duration) > cycle:
cycle = time.monotonic()
# switch pins
okay ill give that a try, just having one turned on while the other is off
raven canopy
@solar whale i can't 100% verify, but i wonder if the hardware flow control (CTS, RTS) is causing the fits since we don't have that available in busio.UART?
solar whale
possibly -- We may need a C module to do some initial reconfiguration of the link or a way to change values in the NVM on the chip to reconfigure the setup.
raven canopy
@solar whale can you try and get the current/defaule UART config on the ESP: AT+UART_CUR/AT+UART_DEF. they'll return: <baudrate>,<databits>,<stopbits>, <parity>,<flow control>
really wishes he ordered an Argon now... 🤦
solar whale
I've been trying , but I don't see the response -- also tries setting them but no effect. It does respond to a AT+RST and resets so there is hope
raven canopy

i mean we dont have to reprogram the ESP3

because the AT command firmware is easy to use - i've written code for it
solar whale
It seem to be respding to some AT commands, but the baudrate seems to be at 921600 and it is hard to get the responses. AT+RST works but I can't get it to allow me to lower the baudrate.

How does one manually mount a flash device on Linux? I'm putting together a workshop and I'm seeing on the Mu site that some distributions don't automatically mount flash devices, and if they don't, you have to manually mount it for Mu to work. So I guess I need to be prepared to explain how to mount CIRCUITPY.
meager fog
umm if the OS can't do it, its going to be a super pain to determine how for each OS 😦
because each distro has different names
idle owl
Oi... ok
idle owl
Noted. I guess if you're running some wonky distro, you better know how to use it.
Exactly 😄
meager fog
this is a rathole you wont get out of, each linux is so different :/
they can run dmesg | tail to see what it might be called
idle owl
Good to know, thank you
solar whale
@meager fog one tricky thing is taht when I sent the AT+RST -- it does RESET, but it alos changes baudrates down to 115200 for the reset then back to 921600 ...
meager fog
oh ok
yeah the code i have is straight 115200
lemme get it into github and you can fork/pr
sound good?
solar whale
great -- thanks!
meager fog
the good news is - i wrote this code 4 years ago in c and it totally was 😦 to do because c is so bad at parsing at strings...but python does it with ease
solar whale
I've ma de a lot of progress since this moring so I am encouraged 😉
idle owl
Does pip3 work in a venv created using python3?
or do you have to use pip at that point
solar whale
np -- take your time
magic wing
I've only played with CP a little bit, basically what I've been exposed to in the Adaboxes
can it be used on most Arduino-based devices or is it only specific boards?
solar whale
@magic wing CP can only be used on the Atmel SAMD21(m0) and SAMD51(m4) , the ESP8266 and the nrf52832 and nrf52840 boards -- the nrf support is still "alpha"
magic wing
Hmm
My "intro" project to electronics has been one of these: http://clearskyinstitute.com/ham/AST/
It's taken me over two years to ramp up on the necessary learning and it's been a lot of fun along the way
and he just recently adapted it to use an ESP8266 instead of the Arduino MEGA2560 which is what I have
I feel a lot more comfortable programming in scripting languages like Python and PowerShell than I do in C/C++ so I was wondering if it might not be better off for me to make the switch
solar whale
It runs on the ESP8266 -- its a bit "differnt" in that tehre is no "native USB" so you can't get the USB drive like on the M0/M4 boards but it works well. -- lokkoing for the link ...
raven canopy
@solar whale @meager fog i've tried to dig through the particle firmware to see if there are any hints as to how they've programmed the ESP. haven't found anything yet, and i'm afraid it will just be a binary anyway... 😦
solar whale
I was hoping thay just used the stock AT command mode but with the higher baudrate... hoping ...
idle owl
The native USB mass storage is the hallmark of the CircuitPython experience. CircuitPython runs on the ESP8266, but it's not the simple experience we always refer to when we talk about CircuitPython being super simple to use, easy to learn, easy to iterate on your code, etc.
magic wing
@solar whale so if I switched the tracker to use the ESP8266 to take advantage of CP, there would be some hardware rework but would allow me to remove a couple of components and simplify the overall system, which in theory means longer battery life because less devices to power/more efficient use. Does that seem a reasonable analysis?
raven canopy
gotta go grab delicious, unhealthy food real quick. then the search continues... 😄 🍔
solar whale
@magic wing here is the guide to using it on the ESP8266 https://learn.adafruit.com/welcome-to-circuitpython/circuitpython-for-esp8266

@raven canopy 🌮 🕰
magic wing
we got an ESP8266 in Feather form in one of the Adaboxes, right?

@idle owl hehe. we had tacos last night... not that i wouldn't eat them again.
@meager fog yeah, i just want to peek if they're setting the UART hardware control enable bit (closed the app notes, don't remember the exact flag).
ruby atlas
sound of typing
meager fog
sommer, its somewhere im sure
ruby atlas
sound of spec sheets being turned
meager fog
but...we can also just reprogram the esp32 with the at firmware we know
raven canopy
@ruby atlas 😆
idle owl
@ruby atlas Hooray!
ruby atlas
Man the trellis m4 rocks.
raven canopy
@meager fog fair point.
ruby atlas
Love the adabox010
solar whale
@meager fog It's not clear how to get at the ESP32 on these bards....
ruby atlas
so do my kids. the mixer in my office was handy to hook it up to.
raven canopy
@solar whale i think there is a way with the CLI and serial.
meager fog
@solar whale im sure they hooked up the reset and gpio0 pins
do u have the schem link handy
meager fog
yeah its all there, wifi_en is the reset line, boot is gpio0 and then theres RX/TX
so you can reprogram it, and then communicate over uart
solar whale
OK -- that may well be the thing to do.
ruby atlas
trellis.pixels._neopixel.brightness = 0.2 ah that's better.
idle owl
@ruby atlas trellis.pixels.brightness works.
Are you using an older version of the library?
ruby atlas
Oh, i was just modifying the original board code.
idle owl
Ah
solar whale
@meager fog I won't jump into trying that yet -- not sure how to access the RX/TX since thay are connected to the nrf52840 -- would you program it through the nrf52840?
solar whale
ah -- I need to do my homework!
meager fog
all good, the chips are programmed over UART, if BOOT is held low
solar whale
cool!
meager fog
its sluggish but you dont have to do it a lot - maybe 2 minutes to program
most of that is python data manipulation stuff, might be optimizable
solar whale
OK -- now I have a better -- "big picture"
I am going to keep trying to get the AT commands to function for awhile then try loading CP to it if I can't get it to communicate nicely.
Thanks for all the help and tips.
luckily I bought a few argons to play with 😉 safe to experiment!
meager fog
we may need to enable CTS/RTS
also there might be a uart bug in nrf, it should have a big buffer
you can check this repo https://github.com/ladyada/Adafruit_CircuitPython_espatcommands
once you have it replying right
or you can try to add rts/cts there
basically you just toggle em to let it know you're ready for data
solar whale
yes -- I am thinking it is not buffering. the ESP32 seems to respond to the command, but the responses are messed up. But a command like AT+RESTORE "should" clear the NVM and put it at the "factory" settings -- I was hoping for 115200 baud -- but that does not work -- it resets on AT+RESTORE but still at 921600 baud.
Great! thanks -- I will dig into it.

Hello all. I'm surprised it's so busy here for a Saturday afternoon/night. I've just loaded CircuitPython 4.0.0 alpha3 onto a Feather M0 Bluefruit LE - what python library should i be using for bluetooth?
simple pulsar
Is that in Feather basic? ```Adafruit CircuitPython 4.0.0-alpha.3 on 2018-11-15; Adafruit Feather M0 Basic with samd21g18
import bleio
Traceback (most recent call last):

ImportError: no module named 'bleio'
solar whale
no -- it is only on the nrf52 boards
simple pulsar
much cuteness
meager fog
you need to use the special bluefruit friend firmware, its not perfect but it mostly works
solar whale
sorry -- I missed the feather m0 part
@simple pulsar that works with the Bluefruit SPI friend.
ugh -- now I see that that is what the "cute" link pointed too --- slow on the uptake today 😉
and it does work with the Bluefruit Feather M0
simple pulsar
@meager fog @solar whale Thanks. Is the library BluefruitSPI going to be used/promoted going forward?
solar whale
any plans to also use the Bluefruit UART Friend with i?
meager fog
🤷
simple pulsar
I'm not sure what that is? I'm new to this world, although I used to be very familiar with AT commands. It's amusing to see these are used
solar whale
The UART friend is nice in that it only need TX/RX as opposed to the 4 lines needed for SPI. Some day -- I'll look into adding support for it.
It's been a long time since "ATDT" 😉
simple pulsar
ATDT, you were lucky, didn't have that when I was young!
ruby atlas
There was a time when I had to use ATDP
It was a digital phone switch but Bell Canada charged extra for touch tone at the time so my parents didn't pay.
simple pulsar
Oh I see: https://www.adafruit.com/product/2479 - I hadn't realised it was a product.
I have one (or two if I can find the one I've lost) of these and was hoping to use them just on their own: https://www.adafruit.com/product/2995
solar whale
and https://www.adafruit.com/product/2633 is the SPI version -- just like the bluefruit on the feather M0 baord
the feather M Bluefruit iworks fine the the BluefriutSPI library..
simple pulsar
I wouldn't classify myself as a novice, perhaps a bit of a bluetooth novice, but this is a hard area to understand what to buy and what libraries work with each, made even worse with the 2.0 vs 4.0 / LE
solar whale
@meager fog I do think there is a problem with the buffering on the nrf UART -- or it just can't handle 921600 baud...
simple pulsar
Does Adafruit have a "configurator" for dev boards? Something along the lines of "would like to 1) use python, 2) use bluetooth" what should I get?
solar whale
Thats what I like to do 😉 break things -- then help fix them.
meager fog
kjw, that is an NP-complete problem, there's a lot of combos 😄
right now if you want circuitpython and bluetooth you can use a feather m0 or m4 (better) plus a SPI bluefruit friend breakout
simple pulsar
If you limit the question and also default to proposing the latest boards then it perhaps wouldn't show too much, but I've not thought of this. I'm just describing what I was after when I added a few to an order a few months back.
Also, I know my friends who are less well informed in this space would be likely to buy an Adafruit CircuitPlayground board. I have to put a lot of emphasis on the Express to make sure they get the right board.
simple pulsar
I also have to confess to buying two Gemma V2 boards as my first boards even when the M0 ones existed.
solar whale
@meager fog looks like the UART buffersize can be set at init on the nrf -- not sure what the default is but I'll try adjusting it. https://github.com/adafruit/circuitpython/blob/master/ports/nrf/common-hal/busio/UART.c#L78
simple pulsar
UART boasts: I upgraded my 16450 to a 16550AFN a long time ago. I think that was from 1 byte to 16 byte buffering
solar whale
doesn't seem to help 😦
meager fog
@solar whale i think it may be some lower-level thing, perhaps we aren't buffering
we should be listening to an IRQ and funnelling data immeditely in
you may want to try the CTS/RTS pins
use those to tell it when you're about to read
solar whale
OK
meager fog
sorry thats all i can suggest for now
solar whale
This has been great -- lot's to work with -- thanks!
simple pulsar
For that cute lamp by @split ocean in the comments it says "Feather M0 Bluefruit LE running the Feather M0 Adalogger build" - is that adalogger build required?

simple pulsar
@meager fog thanks, i'll go play
meager fog
rad bye!
simple pulsar
@solar whale I've not been following your conversation but I presume you get an interrupt when the buffer is XX % full where XX is not 100?
meager fog

solar whale
@simple pulsar good luck -- the IOS and android BLE Connect apps are very nice
simple pulsar
The 16550 "bad boy" you could choose the watermark: https://en.wikipedia.org/wiki/16550_UART#The_16550_FIFO
solar whale
@simple pulsar I have not looked too far "under the hood" on the Uart implentation -- yet.. That is what I'd expect
It also may interrupt when anything received... need to look at the code.
raven canopy
@solar whale i think i'm getting closer to the magic... argon-ncp-firmware (ncp = network coprocessor). here is the block that seems to be setting up the UART: https://github.com/particle-iot/argon-ncp-firmware/blob/master/main/main.cpp#L41
solar whale
ah -- very nice! Thanks -- great discussion earlier -- scroll back -- lots of things to try.
I could not figure out what NCP meant -- I knew it was the ESP32 but not what it stood for!
there is something fishy with the nrf UART. Not clear that buffering is working.
raven canopy
yeah, i read it. didn't jump to the CP lib ladyada did though.
solar whale
perhaps we can just reprogram it with a few adjustments --- lots of info here https://github.com/particle-iot/argon-ncp-firmware
raven canopy
the readme for argon-ncp-firmware says By default, the firmware runs an AT command interface on UART2 (TX: GPIO17, RX: GPIO16, HW flow control disabled).. i just can't determine yet if that is how they are building firmware. all of this is soooo spread out. 😵
solar whale
It sure is --- mesh magic
so I think my attempts to adjust the AT interface baud rate are futile since it this the baud rate between the nrf52840 and the NCP that matter.
time to make dinner -- back later
🍕that was easy!
raven canopy
@solar whale looking at nrf/common-hal/busio/UART, nothing jumps out to me with the ring buffer that would cause any issue. and yes, default buffer is 64 (in shared-bindings).
simple pulsar
I just got the code on https://learn.adafruit.com/munny-lamp/code-with-circuitpython running with the accelerometer code stripped out. It works but there's something odd going on with data that's being buffered in a strange/undesirable way. If i use the control pad on Adafruit Andoid app to generate 'B' commands then it sort-of works but the data gets buffered after a while and only read when new buttons are pressed
solar whale
@simple pulsar post the code you are running. I can try it later tonight it tomorrow.
simple pulsar
Ok, i'll stick it on a forum post in a bit. I'm just trying the debug=True mode but strangely that's giving an error just after the info print
manic glacierBOT
simple pulsar
I'll check it against uart_rx too if I'm feeling keen.
The problem could be at app end too or Android or my tablet, don't have enough BLE experience to make a guess on this
solar whale
@simple pulsar I don’t understand the debug =True reference. Where is that?
simple pulsar
bluefruit = BluefruitSPI(spi_bus, cs, irq, rst, debug=True)

ah -- str.encode needs MICROPY_CPYTHON_COMPAT (not enabled for nrf) https://github.com/adafruit/circuitpython/blob/master/py/objstr.c#L1866

import board
import analogio
import time
GA1A12S202 = analogio.AnalogIn(board.A1)
while True:
rawval = GA1A12S202.value
print(rawval)
time.sleep(3)
how do I convert the raw value into Lux?
main meteor
There's some code to do that here: https://learn.adafruit.com/adafruit-ga1a12s202-log-scale-analog-light-sensor/use-it
upbeat plover
so like this????
import board
import analogio
import time
GA1A12S202 = analogio.AnalogIn(board.A1)
rawRange = 1024
logRange = 5.0
while True:
rawval = GA1A12S202.value
logLux = rawval * logRange / rawRange
print(rawval)
print(10**logLux)
time.sleep(3)
i just ordered it today, so be like a week or so before i can test just wanting to know.....
will save that code
main meteor
I know that "waiting for parts" feeling!

@slender iron is it a known issue that MICROPY_CPYTHON_COMPAT is not enabled for the nrf builds -- if I enable it the build fails with ```jerryneedell@Ubuntu-Macmini:~/circuitpython_jerryn/ports/nrf$ make BOARD=particle_argon
Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity.
