shows the changing clock polarity
teh first LSM CS is "normal" for the default SPI setting - but not for the LSM -- the second is flagged as bad by the salea , but it actually works for the LSM
main meteor
That's some good sleuthing.
solar whale
here I switched the SALEA to match the LSM , but I note that the CS is going low before the clock polarity switches for the first LSM transaction.
@main meteor this has been a puzzling adventure -- I think it is starting to make some sense.
@idle owl @raven canopy and all involved. It really is nice having the examples now part of the "Bundle" One stop shopping! It makes it so much easier to go grab the example. Thank you for implementing that!
tidal kiln
@solar whale i wonder if it's something with spidev? it doesn't actually change SCK until output is run?
solar whale
sounds suspicious ...
tidal kiln
everything higher level seems in order
SPIDevice notionally configures the port before the CS is set:
https://github.com/adafruit/Adafruit_CircuitPython_BusDevice/blob/master/adafruit_bus_device/spi_device.py#L82
on the Feather, maybe that takes effect right away - so SCK is changed before the next line that sets CS
but on the Pi, spidev isn't doing that....maybe?
it just buffers the config changes until a write
so SCK doesn't actually change here:
https://github.com/adafruit/Adafruit_Blinka/blob/master/src/adafruit_blinka/microcontroller/generic_linux/spi.py#L45
solar whale
@tidal kiln interesting -- that would explain why it works on the M4 and not on RPi. Not sure if the root cause it the handling of SCK or CS but they are not independent!
I have to go AFK for awhile back later -- Thanks for digging into this. I learned a lot today ๐
tidal kiln
didn't happen to scope the feather test?
solar whale
no - I will try it later or tomorrow. It' will be good to compare.
tidal kiln
awesome. ok. thanks for all the help also. later.
main meteor
Fixed a SCSI bug like that. The controller would put the data out, assert strobe, take the data away, and wait for ack.
Worked with some targets but not with others. Switching the last two steps fixed it.
idle owl
@slender iron I have to remove the shared.py with shared.I2C_BUS from the Adafruit_CircuitPython_FeatherWing library to get Sphinx to build to put it on PyPI. Otherwise it fails hard. For some reason it's unable to figure out board.SCL and board.SDA. I'm letting you know because I know that was something you wrote into it. I initialised it separately in each file instead and Sphinx builds without errors (which means something changed because last time api.rst wouldn't populate, so this is good).
slender iron
@idle owl did you try adding a board automock?
idle owl
no, but I thought we were trying to avoid any automocks. I'll try it.
that seemed to get it past that part. But now it' failing on No module named 'machine' .. there isn't anything referencing machine...
slender iron
blinka may
idle owl
autodoc: failed to import module 'adafruit_featherwing.motor_featherwing'; the following exception was raised:
No module named 'machine'```we should switch from a shared I2C to using board.I2C
slender iron
blinka uses machine if it thinks its on micropython
idle owl
I mean does board.I2C work on Pi etc. Because the plan is for this code to work on Pi as well.
slender iron
I don't know if it does yet. it'd be good to add though
idle owl
oi, I automocked machine and now it's failing hard. autodoc: failed to import module 'adafruit_featherwing.motor_featherwing'; the following exception was raised: Traceback (most recent call last): File "/Users/kattni/repos/venvpypi/lib/python3.6/site-packages/sphinx/ext/autodoc/importer.py", line 152, in import_module __import__(modname) File "/Users/kattni/repos/Adafruit_CircuitPython_FeatherWing/adafruit_featherwing/motor_featherwing.py", line 36, in <module> from adafruit_featherwing import shared File "/Users/kattni/repos/Adafruit_CircuitPython_FeatherWing/adafruit_featherwing/shared.py", line 35, in <module> I2C_BUS = busio.I2C(board.SCL, board.SDA) File "/Users/kattni/repos/venvpypi/lib/python3.6/site-packages/busio.py", line 15, in __init__ self.init(scl, sda, frequency) File "/Users/kattni/repos/venvpypi/lib/python3.6/site-packages/busio.py", line 23, in init from microcontroller.pin import i2cPorts File "/Users/kattni/repos/venvpypi/lib/python3.6/site-packages/microcontroller/__init__.py", line 36, in <module> raise NotImplementedError("Platform not supported:", platform) NotImplementedError: ('Platform not supported:', 'darwin')
not sure why none of this failed when there was no shared.py
slender iron
with shared.py ReadTheDocs is actually trying to create an I2C bus. try automocking busio
idle owl
Well done, you. But I thought we were avoiding automocks?
slender iron
in general yes
solar whale
@tidal kiln here is how it looks on the feathe_m4 - CS goes low after SCK change
slender iron
but the shared.py is causing ReadTheDocs to do more than it usually does
(It usually just imports a module)
idle owl
ok
tidal kiln
@solar whale as somewhat expected - SCK is high already when CS is set, right?
solar whale
yes
tidal kiln
starting to add up...maybe
i'm sort of heading down a rabbit hole....
https://github.com/doceme/py-spidev/blob/master/spidev_module.c#L864
https://www.kernel.org/doc/Documentation/spi/spidev
seems like if we could find some way to kick it so the settings happen before CS, then we'd be good
@solar whale thanks for adding those to the issue thread
tidal kiln
@solar whale i think i'm done for now. will see what ladyada comes up with. one other thing to mention, not the case here, but some sensors support both polarities of SCK, and they auto detect which one by the state of SCK when CS is asserted. so for those style sensors, this would be an even bigger issue.
solar whale
yeah and some like the stmpe610 just seem t o pick one !
tidal kiln
but it's well documented in the datasheet, right? ๐

hmm -- I still get lots of build failures for many boards -- it seems to keep running and is OK for most of the boards I want but something is not right.. @slender iron or @tulip sleet when yo uhave a chance can you explain how to run tools/build_adafruit_bins.py now -- there must be some new steps
solar whale
may be OK now -- the boards taht don't build appear to be special cases -- I just had not seen then in the past.
and the nrf pca10056 and pca10059 do not geneate .uf2 files
ah - but if I do make BOARD=pca10059 -- i do get a .uf2
slender iron
@raven canopy good work! It may be easier to use the github api instead of git locally
@solar whale are you running it from the tools directory?
solar whale
yes
slender iron
hrm
solar whale
also it tries to build seveal boards taht fails
slender iron
ah ok. I don't think those are built on travis
I must have messed up the flash definition
solar whale
just not used to seeig the erros -- it keeps going and build the rest
has tehre been a chang ein the bluetooth driver downloads -- looks like only 2.0.1 iss downloaded - ther others are in the repo now, correct?
slender iron
it now builds based on listing the board directories versus and hand coded list
correct
solar whale
OK -- I think I'm back on track -- still puzled aboyt nrf .uf2 -- I get tehm if I do a manual make BOARD=pca10059

slender iron
@neon dragon awesome. I'm adding board defines for all three now
neon dragon
They are identical, not? Until we flash micropython to the ESP32 on the Argon.
neon dragon
Beware: I think the green flash chip on that diagram is incorrect. My board description has the correct one (I hope). Not sure if there are other errors in that schematic, better work from the Eagle docs.
slender iron
its not the MX25L1606?
have you thought about trying to leave the bootloader in tact?
ah, I see you have MX25L3233F in your repo
gonna go grab dinner. will be on later
I need to look closer at your repo. the added classes are interesting!
neon dragon
I'm not 100% sure about the flash chip. A while back they made an announcement that they switched from 2MB to 4MB flash chips. For the ESP32 they show the 4MB part, but the 2MB for the nRF. Moreover their memory map adds up to 4MB. So I expect 4MB is correct. It works but I have not tried to copy 4MB. No, I have not tried to keep the particle bootloader (supposedly its dfu, but flashing just "bricked" the device). Your bootloader is very slick, I don't need another.

I'm trying to hijack some of the fonts from the Adafruit-GFX-Library, like this one: https://github.com/adafruit/Adafruit-GFX-Library/blob/master/Fonts/FreeMono12pt7b.h
I'm just not understanding the encoding at all. For the 5x7 font it was easy, each line was a separate character, but with these other fonts I can't figure out how to interpret a character.
For the 5x7 font, it's pretty clear it's the following where each column is a 0xAA hexadecimal number from the table, and then each line of hex numbers is a character.

surround your code with

so it looks cleaner
how do you do a 3 cycle delay in circuitpython?
raven canopy
@slender iron use the api for which part?
slender iron
@raven canopy use it for editing the file and committing
raven canopy
hmm...that is a big refactor, no?
to clarify (which i may have not done well enough to start), i'm battling this fail from the cron jobs:
exotic pumice
delay_cycles isn't exposed and I imagine even if it was it would have additional overhead
raven canopy
@exotic pumice you could probably use time.monotonic() and microcontroller.cpu.frequency to math your way there. monotonic is based on SysTick.
raven canopy
won't be super precise...but close enough i imagine.
slender iron
@raven canopy ya, big refactor. I wasn't thinking about the submodule stuff it does
raven canopy
hehe. zactly. i was just about to pull up the api docs to see if that is even possible. ๐
velvet badger
Does the SR04 need 5v to work right with circuit python?
I get errors raised with test code every time. I've tried on a couple of feather boards.
raven canopy
@velvet badger looking at the guide, it shows it working with >1K ohm on the Echo pin. guide also notes that it is more accurate with 5V.
exotic pumice
@raven canopy, I'm printing time.monotonic, and it looks like millisecond precision
raven canopy
yep. i think a monotonic_us was recently added, actually.
exotic pumice
perhaps I need to pull
>>> dir(time)
['__name__', 'monotonic', 'sleep', 'struct_time', 'localtime', 'mktime', 'time']
>>> dir(time.monotonic)
[]
>>> dir(time.time)
[]
>>>
this is 3.1.1
velvet badger
Thanks @raven canopy
raven canopy
@velvet badger yw!
@exotic pumice ahh. it was actually monotonic_ns, and yeah i think its only in master (4.x)
raven canopy
@exotic pumice SysTick is configed (SAMD at least) to roll over each millisecond. my understanding is that one full rotation of SysTick is a "cycle". i may be wrong though; happens plenty. :D
https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/tick.c
so, "delay 3 cycles" would be time.sleep(0.003) or microcontroller.delay_us(3000). yes?
exotic pumice
no, a cycle would be 1/5MHz or 200ns
would a hardware timer be a better idea and do I have access to those through circuitpython?
raven canopy
timers aren't available. i think there is an issue to bring them to the python side...
nope. that was for making it easier on the C side. ๐ฆ
@exotic pumice if you need absolutely nothing happening during your wait, i think microcontroller.delay_us(1) is the shortest you'll get. time.sleep() will allow the VM to run if you need interrupts/periphs.
exotic pumice
hmm
I'll see what I can do but it sounds like I might have to go back into C or Rust
raven canopy
the crux of the python side. fine scale timing just doesn't pan out as easily..
raven canopy
with delay_us(), looks int only. time.sleep() will take the float, but checks the procession of us...so i would say no.
@slender iron using the api might be possible. but i imagine i personally would break sooo many things. ๐
https://developer.github.com/v3/git/#git-data
exotic pumice
I'll have to see what the lower bound of speed is for SWD. DAPLink uses 2 or 5MHz, but possibly it is lower than that
according to the samd21 datasheet the clock for swd can be as low as 1KHz
so that's promising
slender iron
@raven canopy ya, I think you are on the right track
raven canopy

how do I bitbang synchronized to a clock and output that clock at the same time?
I guess just bang up and down the clock before I do anything that would take a clock cycle?
that doesn't really make sense either
slender iron
right, you set the clock pin intermixed with setting the data pin
exotic pumice
time.monotonic_ns seems like it's just time_monotonic * 1 000 000
or maybe that's print speed?
no, because I'm doing the timing independently of the prints actually
import time
import microcontroller
start_time = time.monotonic_ns()
microcontroller.delay_us(1)
end_time = time.monotonic_ns()
print(end_time-start_time)
ok, so I need a logic analyzer to figure out if I'm doing anything faster than 1kHz
that sparkfun one looked decent
for the price
and there's some on aliexpress too

@slender iron thank you for your reply. The MCU is running in an isolated area in a low voltage mode. (1.9V I think). When we designed the board we were not aware of circuitpython and therefore we were happy with plain UART communication as it was easy to isolate. However since we know about circuitpython now I would love to try it out.
So any pointers at what do do to get it working with just UART (if it is possible at all) are highly appreciated

I have a feeling it should be able to ask itself for an ID, because swd can work while other things are running, so there is probably something wrong with my code

Hi All, coming back to CPY after a break - I used V2 on my ATSAMD21E18 Keypad, and I'm looking to make a Bluetooth/USB version using an nRF52840 module.

@tannewt does the error on the image above is causing the last Travis job to fail?
slender iron
@jovial pine I don't know of one. I used a JLink to load a new bootloader on one.
jovial pine
@tannewt Thanks. I'll dig out my J-Link in the morning. Did you just solder wires to the board or mount a header?
scenic timber
Not sure if this is the correct channel but I think the https://learn.adafruit.com/adafruit-crickit-creative-robotic-interactive-construction-kit/programming-options#crickit-hat-for-raspberry-pi-14-6 should include the instruction "pip3 install adafruit-circuitpython-crickit"
I didn't see that instruction in the Installing Circuitpython on a pi either. Just took a guess and stuff started to work ๐
Then I am guessing just follow the feather wing code?

@jovial pine I can't recall. I do have extra headers for this purpose

@native palm you would need to install blinka and there would need to be support in blinka for the board you are using:

blinka is the software interface between CP libraries and specific linux targets

What's the best way to "bridge" the USB on an nRF52840 to the UART? Application: esptool to flash micropython to the esp32 on particle Argon boards.
crude fossil
@neon dragon I'm not sure, but I suspect it'll be to create another serial port in the USB profile, and then just echo bytes back and forth. I've been messing with something similar in https://nick.zoic.org/art/micropython-webusb/
By making the serial appear as a separate serial port on the same device, you can still use all the usual serial UART based tools.
neon dragon
I see this is a bit of work. Perhaps I just try to port limited esptool functionality to CircuitPython and run this on the nRF52840.
crude fossil
What are you trying to do? Run MicroPython on the '32 or CircuitPython on the nRF or both?
or either ๐
On another note, I'm not sure that the https://www.nordicsemi.com/eng/nordic/download_resource/$ETC URLs used by the NRF port to download the bluetooth stack still work ... download_ble_stack.sh is failing for me ...
neon dragon
Nick: particle released a board that has an nRF52840 as the main processor and an ESP32 attached over UART for wifi. I want to reflash the ESP32 with micropython. The nRF runs CircuitPython. The ESP32 is not directly accessible, only via the nRF. Hence I cannot run esptool in the usual way.
BTW: getting the ESP32 into bootloader mode works fine. But it's in SPI_FAST_FLASH_BOOT. Anybody knows what that means?
night vale
I am using CircuitPython on a Raspberry Pi (3B+, I believe) and the adafruit_74hc595.ShiftRegister74HC595 library trying to control a bunch of power outlets (for Christmas lights and in place of light switches). It appears the library can only handle a single 74HC595 chip. I currently have 2 chips and planned to add more. Do I just need to use the SPI directly or does anyone know if the library can support more than a single chip?
manic glacierBOT
idle owl
@night vale That library was very recently created, we did not test it with multiple chips. I don't know what would need to happen with it to support multiple chips. So if accessing the SPI directly works, I would suggest going that route.
manic glacierBOT
night vale
@idle owl Thank you for the quick response. When I hooked up the second chip, it appears it is simply ignoring the output past the 7 pins, so whatever the last value loaded into the first 74HC595 gets passed on to the second 74HC595. I will use the SPI directly. Thanks!
idle owl
@night vale Feel free to file an issue on the 74HC595 GitHub repo requesting support for multiple chips, if it's something you'd like to see. If it turns out it's not possible, we will have at least looked into it. https://github.com/adafruit/Adafruit_CircuitPython_74HC595
crude fossil
@neon dragon yep, I know of the board ... SPI_FAST_FLASH_BOOT is the normal boot mode I think, it should be DOWNLOAD_BOOT for bootloader use https://github.com/espressif/esptool/wiki/ESP32-Boot-Mode-Selection#boot-mode-message
I think you're right in that you could get away with having CircuitPython on the nRF CPU act as a relay to the ESP32 UART ... it'd have to be a "load through" kind of mode to use the usual tools though

@slender iron hey by the way the nrfjprog download has similarly moved.
slender iron
@granite crow I'm not sure why its called #1 but it looks right. travis passing means you haven't broken CP. Even if you do, we can always fix it

exotic pumice
Ok thanks
main meteor
I was out for the day. Looks pretty much like the C version to me. Not sure if the timing is critical, but if so, might need to tweak some things.
exotic pumice
I don't think timing is critical. It looks like it can range from like 5MHz to 1 or 10KHz
that's based on daplink using 2-5MHz and atmel datasheet saying the timing for a low and high swd pulse can be as long as 5000000ns (not sure the exact number of zeros but I checked earlier)
exotic pumice
I think we're at like 500KHz?
don't have a logic analyzer to check though
oh this is a thing https://github.com/adafruit/Adafruit_DAP
any compelling reason to not just use that?

is there an mqtt module for circuitpython?
exotic pumice

scenic timber
I'd like to port some holiday LED projects from arduino to circuitpython/seasaw
they use mqtt to get the commands as to which animations to run.
lime trellis
@scenic timber (in case you didn't know) there's mqtt support on the master micropython repo. might give you a starting point
lime trellis
thank you @slender iron I found another workaround. Is there a good explanation somewhere on why some pins can only be RX or TX? I can't seem to find any mention in the SAMD datasheet
exotic pumice
I think it's to do with SERCOM pad layout
slender iron
yup, look at the pinmux table and cross reference it with the pad settings for the UART sercom mode
exotic pumice
@slender iron were you aware of Adafruit_DAP?
slender iron
no
scenic timber
@lime trellis thanks Iโll check it out!
exotic pumice
I don't see much reason to port it, do you?
lime trellis
@slender iron can you point me towards the UART sercom pad settings?
exotic pumice
@lime trellis SERCOM5/PAD[1]
lime trellis
@exotic pumice yeah but where does it say that SERCOM5/PAD[1] can only be TX or RX?
exotic pumice
the UART section of the datasheet probably
lime trellis
I've combed through it, and their app-note. but I must be blind
I was hoping it was something I could set when configuring SERCOM5 somewhere
exotic pumice
if not, I can try to pull up some docs from a library I've used
lime trellis
@marble hornet I believe it's only on hard resets
slender iron
@lime trellis look in the CTRL register of the UART sectin
exotic pumice
@lime trellis I have a list of the pinouts here https://atsamd-rs.github.io/atsamd/atsamd21g18a/atsamd21_hal/sercom/enum.UART5Pinout.html
lime trellis
๐ I'll look right now
marble hornet
thank you !
lime trellis
wow, if this is it then it's pretty obscured!
so if I read this right.... TX can NEVER be on a PAD[1]??
exotic pumice
I think it's only pad 0 and pad 2

@tulip sleet when I was asking about uart was a way to represent strings packed into bytes mentioned?

takes a string and returns a bytearray
tulip sleet
yeah, but that's not present in the smaller non-express builds
exotic pumice
ah bummer
tulip sleet
BUT, the workaround is:
bytes(some_string, 'ascii')
and in fact the second arg to bytes() is ignored (just like the arg to encode() is ignored. It's a MicroPython thing (or "deficiency"), or something.
@marble hornet ^^

@tulip sleet could you please, if you're free, give me some help "parsing ๐ " the nvm files? i can't find where the name of the module actually defined.
tulip sleet
hi, here is where the nvm name is defined: https://github.com/adafruit/circuitpython/blob/master/shared-bindings/nvm/__init__.c#L52. the MP_QSTR_nvm gets converted to something else completely during the qstr generation phase of a build.
it's kind of hacky. there are substitutions made for certain strings that turn into certain characters
granite crow
Hi, are there plans to suport the Bluefruit nRF52 board in Circuitpython?
tulip sleet
yes, that's the 52832 board, but we are also coming out with 52840 boards
marble hornet
to me, on 3.x, it isn't in string form ? so the name MP_QSTR_nvm is turned into the name?
tulip sleet
Yes, there's a preprocessing pass that looks for MP_QSTR_<something>, and builds a table of qstrs (compile-time shared string definitions).
see py/makeqstrdefs.py and py/makeqstrdata.py
marble hornet
so if i wanted to change it would i would just replace nvm right?
granite crow
@tulip sleet Sounds great, i'm seeing the Bluefruit with the Mynewt bootloader, can i go back and forth between Mynewt and Circuitpython (using just a SWD programmer i guess)?
tulip sleet
@marble hornet right
@granite crow in theory yes -- the newer boards will have a uf2 bootloader like other CircuitPython boards and that will be a lot easier to load. I'm not sure what you might smash if you overwrite stuff on the Mynewt board. I don't remember whether we have firmware images to reload (probably we do).

lone sandalBOT

@charred blaze you would do something like serial1 = busio.UART(board.TX, board.RX) and then write to the UART object. Of course you don't have to call it serial1
charred blaze
Ahhhhh ok! thank you danh!!
apologies @stuck elbow i guess I meant UART with the RX/TX pins.
stuck elbow
@charred blaze ah, I see, like on the arduino leonardo
charred blaze
Im not sure. never used a leonardo.
slender iron
@marble hornet @stuck elbow SPI should work from boot.py. Only usb isn't up yet.
@timber mango you'll need to make a supervisor/serial.c in ports/atmel-samd/ that implements the supervisor/serial.h API and change the Makefile to use it instead.

the neopixel.NeoPixel creations are inside the while True loop, so they happen over and over. Move the btns = and strip = out before the while True loop
and the other stuff is in the loop too, which probably only needs to happen once. so move that out. For now, just do

It seems to me that reverse mounted LEDs would be straightforward (you may have thought so too), so now I'm curious as to what difficulties you ran into.

@exotic pumice I figured as much. I was originally trying to make it alternate colors for the moment to get them working

tidal kiln
@idle owl there were....let me guess...
idle owl
@tidal kiln ๐
tidal kiln
no worries. will do. actually want to set one up to check one of those issues posted in the soon to be deprecated repo
idle owl
Sounds good, thanks you for both!
@tidal kiln Can you do the release on ADS1x15? You'll know better what to put in the release notes, noting that it breaks the API.
tidal kiln
yep
idle owl
Thank you!
tidal kiln
idle owl
That'll work. Thanks!
Trying to come up with a name for a lib. I'm pulling the Motor FeatherWing helper code out into its own library because it works on the Motor Pi Hat (and presumably the shield though that's to be tested soon). Adafruit_CircuitPython_MotorAddOn ? "add-on" was mentioned as a general name for shields/hats/wings. I don't know if I like it though. MotorKit? MotorHelper? I'm trying to picture what the import will look like and I want it to make sense. Add-on might be growing on me.
tulip sleet
@idle owl MotorBoard?
idle owl
hmm
tidal kiln
MotorBoard seems OK, marketing may not like it though
charred blaze
Motor Mover!!!
tidal kiln
MotorFHS? (Feather Hat Shield)
raven canopy
@tidal kiln needs a B for Bonnet. ๐
tidal kiln
oh wait, it's a wing
raven canopy
oh...and a W
charred blaze
M Wing (like he X Wing) but M is for motor
tidal kiln
MotorParty
charred blaze
I still like my idea the Motor Mover!!!! (You gotta keep the exclamation points in there too)
tidal kiln
MotorWiSH (Wing Shield Hat)
charred blaze
You forgot the silent B, for bonnet, like Sommersoft said
tidal kiln
it's a non printing unicode character
charred blaze
Ahhh ok
What about WooooooooSH instead of WiSH? With the oooooo being the circles your motors will spin???
tidal kiln
MotorV8R
idle owl
So I'm not sure there's a motor bonnet kit anyway. I don't know ๐
idle owl
It can't be wing specific, it already is and we're moving away from that. I love MotorParty but I don't think that explains much. MotorWiSH is pretty great.
tidal kiln
MotorChimera
idle owl
haha
There isn't a motor bonnet. But there's also no guarantee there won't eventually be.
harrumph.
tidal kiln
indeed. surprised there isn't one already. there is a servo one.
idle owl
Yep
tidal kiln
motor one would basically just be that + h bridges
and since it all fits on a wing, not a space issue
idle owl
MotorBWiSH? Preempt it? ๐
AddOn isn't much less general than Board.
Kit isn't in all of the descriptions, only the shield and hat descriptions
EasyMotor?
SimpleMotor?
Go the other direction and highlight it's ease of use instead of what it's for?... bleh
Now I want to have an excuse to say "bwish" though.
Helper is .. not good.
tidal kiln
Motor1A39 (all 3 PID's added up and converted to hex)
idle owl
LOL
Well played
MotorStepper?
Those are the two properties contained within.
well there's 6 but it's motor1,2,3,4 and stepper1,2
Makes it seem like maybe it's for steppers though, not also for dc motors
DCMotorStepper?
Eh.
tidal kiln
MotorStepper is ok, in that context should be obvious it's two things
idle owl
Think so?
tidal kiln
"stepper motor" means one thing, but by flipping them, seems ok
idle owl
that was my thought but then I second guessed it.
tidal kiln
if it were truly only for steppers, you would either say "Stepper" or "StepperMotor"
charred blaze
"Mighty Motor Mover" ???
idle owl
Points for creativity ๐
charred blaze
Woooo!
idle owl
More points for alliteration
charred blaze
idle owl
If you fits, you sits.
charred blaze
Hang on.... I have a better response to that one. just gotta find it
idle owl
Ok, one more but then we're done or it should move to #general-chat
charred blaze
Here you go Kattni. and YES, thats me inside there.
ok, back to circuit python topics lol
cosmic patrol
Hello everyone! I've been trying to get the SleepyDog library to work on an Adafruit feather M0 basic. The micro seems to draw far too much power in deepSleep mode(0.75mA at 3.3V external supply). I raised an issue in the repo and would love any suggestions for what I could try to reduce the power consumption. Thanks in advance!
sacred edge
Why when I name a python section of code anything other than "Code.py" It will not execute?
idle owl
@sacred edge There are a few filenames that run automatically. CircuitPython looks for code.py. If you name it something else, it doesn't look for it, that's why it doesn't execute.
cosmic patrol
@sacred edge Here's more info on the topic: https://learn.adafruit.com/welcome-to-circuitpython/creating-and-editing-code#naming-your-program-file-6-30
sacred edge
idle owl
Yes, when you're ready to run your code.py file, copy it to CIRCUITPY and it will run automatically.
Unless you have an error, in which case, begin troubleshooting ๐
sacred edge
Thanks!!.. Wow.. This is getting interesting knowing the little bits and pieces to writing and running the code..
idle owl
You're welcome! The more you get into it, the more you learn ๐

@exotic pumice from today's meeting question?

@slender iron thank you
upbeat plover
Can i use this https://www.datasheets360.com/pdf/-9101609953768848923 with feather m4 express? I have power, ground, CS, SCK, MO, MI all connected but dont know how to do anything with it
tidal kiln
datasheet time! seems possible, just need to work through the details in the datasheet. have you done anything like this before?
upbeat plover
never...
i would like to learn though
i find useful chips in all kinds of discarded/antiquated devices
tidal kiln
are you familiar with SPI in a general sense - the basic idea of how it works, what CS does, etc?
upbeat plover
no, i think you have to pull cs down to do stuff?
should i add pins for hold and write protect pin?
tidal kiln
in general yes, and you can see some traces in the datasheet. but SPI is a general communication thing, not specific to this chip. so i'd first do some reading on SPI.
upbeat plover
i read this already https://learn.adafruit.com/circuitpython-basics-i2c-and-spi/spi-devices
tidal kiln
that's a little too high level, only covering the software aspects
but it links to ye 'ole wikipedia
so that level of reading
upbeat plover
this was my first failed attempt
import board
import digitalio
import busio
from adafruit_bus_device.spi_device import SPIDevice
import time
cs = digitalio.DigitalInOut(board.A5)
cs.direction = digitalio.Direction.OUTPUT
cs.value = True
spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)
device = SPIDevice(spi, cs, baudrate=5000000, polarity=0, phase=0)
time.sleep(4)
while True:
with device:
cs.value = False
result = bytearray(256)
spi.readinto(result)
cs.value = True
break
nvm that was like 3 or 4th... lol
tidal kiln
yep. backup and read about SPI - how it's working under the hood.
i think it will be difficult and frustrating to try to just do it by iterating on software
upbeat plover
reading the wiki now
tidal kiln
you'll want to really understand what CS/SCK/MOSI/MISO do
read the wiki, the datasheet, and also maybe an existing CP driver for a SPI device
upbeat plover
for the mode, the chip im using can do 0 or 3, but the wiki doesnt really tell what "Clock edge
(CKE/NCPHA) " is
tidal kiln
it looks like it's just the terminology for clock and phase for a specific microcontroller
so, typical datasheet fun, you've already found that good bit of info - "Both SPI bus mode 0 and 3 are supported"
the next question is how the chip gets set to one or the other....hopefully it's in the datasheet somewhere...maybe inferred from the diagrams....buried in a footer note....google for errata...??? etc.
however it works, just use mode 0
and what the datasheet is calling "Standard SPI"
upbeat plover
datasheet references the HOLD# and WP# pins alot i think i need to wire that to like board.A4 and board.A3?
currently board.A5 is my cs
raven canopy
@upbeat plover the interaction with that chip looks a lot like the FRAM chip I just dealt with. HOLD and WP aren't required, from what I can see.
upbeat plover
i was looking at the "block diagram" it looks like nothing can be done without the "write control logic"
im very new to this so im probably mistaken
upbeat plover
wow, might take a bit to look through that
tidal kiln
it will, but you've got good info to go on
a combination of general info like the wiki page to understand SPI + the specifics in the datasheet to understand your device + examples like above for helpful reference
upbeat plover
yeah thanks for info guys
idle owl
@prime flower I see you're working on TinyLoRa
prime flower
@idle owl yep! implementing a bunch of cater's changes
idle owl
Right on.
prime flower
cleaning it up and then I was going to ping you re: linting issues,
prime flower
absolutely, thank you
tidal kiln
yep
prime flower
Yeap, that's the encoding
upbeat plover
ty
idle owl
@tidal kiln Let me know if/when you'd like help deprecating the ADS1x15 Python library. I was pinged to assist.
tidal kiln
you wanna just do it?
idle owl
I've got plenty on my plate. More importantly, it may be a process worth knowing how to do as the plan is to deprecate as many as possible.
tidal kiln
ok. maybe later today then.
idle owl
Whenever works for you is fine, I was going through my list and helping you with that was on it so I pinged.
tidal kiln
okie dokie. i'm wading through the forums swamp for a bit. will try and ping you later.
idle owl
I have to leave for the evening around 1800EST. If we don't get to it today, that's ok.
prime flower
@idle owl alright, lib. is at a good point to sort out the issues.
@tidal kiln thanks for such a comprehensive review
tidal kiln
@prime flower np. i think it was mainly a lot of "make it more pythonic" suggestions.
idle owl
@prime flower Ok.
Everything is happy with an __init__.py file in the packages directory, correct?
prime flower
@idle owl yeah (just tested), it removes the no-name-in-module error
idle owl
@prime flower Out of curiosity, what version of Pylint are you running locally?
prime flower
2.1.1
tulip sleet
that's too bad - i thought it would be happier in 2.1.1
idle owl
We were postulating that it might be resolved in Pylint 2.x
And still trying to figure out why there are other libs that work fine without an init.py file.
I feel like it's not worth blocking this for us to try to figure this out.
tulip sleet
someone like me needs to sit down and figure this out once and for all. https://github.com/adafruit/Adafruit_CircuitPython_Bundle/issues/77 is a good place to discuss this.
idle owl
Indeed ๐
tulip sleet
but i'm not going to do that now
idle owl
@prime flower Please include the __init__.py file, but include a comment/docstring that explains why it's necessary since we are putting in an effort to move away from it and I'd rather not have someone else come along and go through this whole thing again when we've already done it.
We'll deal with figuring out what is different about your lib another time.
Since it doesn't seem like anything should be ๐
prime flower
Incl. the docstring inside the __init__.py explaining it?
idle owl
Yes please
Doesn't have to be super long, but explain that without it pylint fails with the following errors, we should revisit this when we can look into it or something like that
slender iron
what is the lint error that requires init.py?
prime flower
no-name-in-module
tulip sleet
pylint doesn't seem to realize it's a package
slender iron
what is the context of the error? is it linting an example
tulip sleet
https://stackoverflow.com/questions/48024049/pylint-raises-error-if-directory-doesnt-contain-init-py-file especially see last answer
raven canopy
According to pydocs (3.7.1), packages still require an __init__.py to treat directories as a package. https://docs.python.org/3/tutorial/modules.html#packages
finite coral
Hey guys, question for ya.
I'm playing some WAV files when my Circuit Playground is tapped. But it's occasionally throwing a memory allocation error.
Do I need to some how... free the old objects or close the previous file... ? before playing a new WAV file? Each file can play at least once... but occasionally, when the played file changes, it's crashing.
slender iron
@raven canopy ah, that makes sense. if you have subdirectories then you need an init.py
@finite coral how are you playing the file?
finite coral
@slender iron
audio = audioio.AudioOut(board.A0)
wave = 0
def play_file_two(filename):
global wave
global currentlyLoadedFilename
print("Playing sound: " + filename)
# the requested filename is different from the previous one,
# so open the file and play
if currentlyLoadedFilename != filename:
wave_file = open(filename, "rb")
wave = audioio.WaveFile(wave_file)
currentlyLoadedFilename = filename
audio.play(wave)
# the requested filename is the same as the last one,
# so don't reload the WAV file if it is already open
else:
audio.play(wave)
I kinda hacked apart some of the sample code.
Detecting a tap calls this function. But only if the audio isn't currently playing.
prime flower
@idle owl with travis passing, OK to merge into master? Git's site alerts me that squash and merge is not enabled for this repository
tulip sleet
we don't do squashes any more, so merge is fine
tulip sleet
about no squash? we stopped doing squashes more than a year ago (starting on the circuitpython repo). If it's still enabled on some repos that's left over
prime flower
maybe still enabled on some of the arduino libs ive worked on.. ๐คท
idle owl
We haven't disabled it for Arduino. It's a CircuitPython specific thing
@prime flower Do you want me to merge it?
prime flower
that'd be great, thank you
tulip sleet
we decided it wasn't worth it for commit "cleanliness". the commits show a good history of the dev process; we don't really need to hide the intermediate steps.
idle owl
We strive for transparency and it can be a great learning experience for others.
@prime flower Done.
prime flower
Thanks!
vague folio
Hi everyone, I'm new to CircuitPython, and I had a question about the libraries. I'm using the INA219 library, and noticed that the chip has more features than are implemented in the library (power register, etc). Were these not implemented intentionally to save space? Or has no one gotten around to it? (If the latter, I hope to help out by implementing those)
finite coral
@slender iron
Hmm... welp, I didn't find the problem, but I think I found a solution.
Before playing a new WAV file, I call audio.deinit(), immediately followed by gc.collect() to free up some memory manually. ยฏ_(ใ)_/ยฏ
idle owl
@vague folio I'm betting it's that no one has gotten around to it.
tulip sleet
@vague folio the CircuitPython library usually takes its lead from the earlier Arduino library -- not sure what was done in this case.
vague folio
@idle owl Ok, good to know. So just to double check, if I were to update the library to implement all the features of the chip, that would be ok? (I will be needing help to navigate the github process, but that's another topic)
@tulip sleet Also good to know. I also can update the arduino/c library, as I'm going to be using that as well. Does that work?
idle owl
@vague folio That would be great! We have design guidelines and so on to follow. And as for Git and GitHub, I wrote a guide on that process, so you can check that out as a place to start. https://learn.adafruit.com/contribute-to-circuitpython-with-git-and-github/overview
slender iron
@finite coral I'm glad you sorted it out
vague folio
@idle owl Thanks for the link. If you don't mind, could I reach out to you directly if I have any questions with that?
(I apologize to those other users starting with Katt*. Turns out I should check my mentions before hitting enter.)
idle owl
Absolutely. But there are also many people here who can answer questions too. ๐
If I'm around, I'm happy to help
vague folio
ok cool, will do
idle owl
@slender iron We have a number of libraries that have packages that do not require an __init__.py file. That's why we were looking into it. We'll deal with it when we have more time to look into what the deal is.
prime flower
@idle owl created a branch for pypi, going to submit a PR, can I tag you for reviewing?
idle owl
@prime flower Yes please
slender iron
@idle owl ya, seems like its inconsistent when its needed and we should just add them
idle owl
There was discussion that concluded we shouldn't use them.
ยฏ_(ใ)_/ยฏ
There's already an issue open for it. We'll sort it when we get to it.
tulip sleet
i'm confused by the pointer to the 3.7.1 doc that says they're needed, cause Python 3 started making them optional. I need to sort all this out.
raven canopy
@tulip sleet I was confused as well, especially since your aforementioned statement of "3.x optional".
slender iron
the optional thing comes from this: https://www.python.org/dev/peps/pep-0420/
and it seems having init.py leads to more predictable behavior
exotic pumice
lmao
prime flower
@idle owl This initial release would be v1.0.0, correct?
(not sure if the travis config would be ok with pre-release versions for verifying)
idle owl
@prime flower Sure. Or if you feel like it's not entirely done yet, or you know there are more features to be added you can start at 0.x.0. Version numbers are free, so you can choose what you think makes the most sense.
tidal kiln
@prime flower in case you haven't read yet:
https://semver.org/
i don't think it answers the question of what the initial number should be, but does explain what the 3 digits are for
prime flower
thanks for the link, I just wasn't sure if travis would release differently if I didn't do a 1.0.0
idle owl
No, it doesn't care, it simply wants a release.
@prime flower Travis failed on auth info for PyPI deployment.
prime flower
just saw that...I manually typed in the password too after it prompted me
finite coral
Any tips for improving NeoPixel animation speeds?
When I change the value of all 10 NeoPixels on the CircuitPlayground express, it takes about 250ms.
This is with my neopixel.NeoPixel() initializer with auto_write set to False.
Conversly, only setting a single NeoPixel is pretty darn fast.
idle owl
@prime flower What I've been doing when something like this happens is deleting the release, deleting the tag, and starting fresh.
@prime flower There's a process to do this though.
prime flower
oh jeez that @ came in right as I was doing a release
idle owl
Heh ok. That's fine.
Please include this entire section in every release, @prime flower: ```To use in CircuitPython, download the .mpy file and copy it to the lib folder on the CIRCUITPY drive. Or, simply install the Adafruit CircuitPython bundle.
To use in CPython, pip install adafruit-circuitpython-<libname>.
Read the docs for info on how to use it.```
Also apparently you didn't update the libname part. I pasted that out of the initial release.
prime flower
yeah, I saw that
added the entire section to my notes on this
didnt deploy again...invalid option "--api_key="
idle owl
I looked at it, it passed....
prime flower
the tagged build?
prime flower
shows failed on my other tab...weird
idle owl
Travis can be weird with updating to a new build sometimes.
prime flower
ok, great. Just exported my notes on the process to dropbox. thanks for the help
idle owl
@prime flower At some point we need to figure out why you can't encrypt the password successfully or you'll always need someone to fix it, or need someone else to do the entire process. Right now isn't great, but we should probably keep it on our radar.
prime flower
I agree, I'd like to know why it isn't encrypting either..
are the instructions for building the bundle still valid? I can't seem to find build-bundle.py in the current repo
idle owl
I don't run that. I do the submodule add only. I commit, push, and then verify in the PR that I've only updated .gitmodules and added module at point <hash>.
I didn't even know about that step.
slender iron
@tulip sleet want to wait for a ladyada review before merging your UART PR?
tulip sleet
@slender iron I did test it. You can go ahead and merge and that will give a good build for her to test more thoroughly. thanks!

@prime flower Congratulations on the TinyLoRa release!! Woo Hoo! I just ran a quick test on my RaspBerry Pi -- wroked fine with one samll detail. the ttn_*.py files are not "installed" by pip3 -- should they have been? -- I had to copy them to the local folder. No big deal, but just a surprise.
sorry -- they are installed but my system did not find them -- may be something on my end --
prime flower
@solar whale They should have been...was the encryption file included as well?
might be an issue with the setup.py not sourcing them?
solar whale
yes - they are there --trying to figure out why python could not find them.. It worked fine when I copied just them into my folder --
have you treid it on a RPi?
prime flower
not yet
solar whale
OK -- It may be my problem -- I'll keep looking -- Nice job!!
prime flower
thanks. it;s probably that line of setup, though. i cant think of anywhere else where those files would be imported.
