you use it once in a while, it could b its own lib
#circuitpython-dev
meager fog
umbral dagger
@meager fog Just saw your comment. It could definitely be a separate lib. I've done a more general version that "debounces" a lambda expression that can be quite useful (i.e. not limted to just onboard GPIO pins: seesaw/crickit inputs, a noisey analog input, etc).
slender iron
@tulip sleet up, thats true
tidal kiln
Debouncer - sounds like Trailing Whitespace doing a Pixies cover
meager fog
lol
i think its a good helper, @umbral dagger wanna work with @idle owl to make it it's own helper library?
there was one for arduino people liked, i could see a button pal library being helpful
umbral dagger
@meager fog Do you want a guide explaining it? It's actually based on the Arduino one.
ruby lake
@meager fog now for a featherwing that has 4x 0~5v 12 or 16-bit DAC channels and 4x logic I/O ๐
solar whale
woohoo!
tulip sleet
great!
slender iron
- hopefully
tulip sleet
i'll try it on windows too
slender iron
in tinyusb, samd21/dcd.c
// A setup token can occur immediately after an OUT STATUS packet.
if (epnum == 0 && dir == 0 && buffer == NULL) {
buffer = control_out_buffer;
}
in dcd_edpt_xfer
before bank->ADDR.reg = (uint32_t) buffer;
(I have a bunch of debugging changes in my repo atm)
tulip sleet
should we start with careful-reset branch?
slender iron
ya, I think those changes are still helpful
solar whale
can you give full path to samd21
tulip sleet
./src/portable/microchip/samd21/dcd.c
solar whale
tnx
slender iron
within lib/tinyusb
the setup interrupt was reading 0x0 as its source for the setup packet ๐คฆ
tulip sleet
does this not happen on samd51?
UsbDeviceDescBank* bank = &sram_registers[epnum][dir];
UsbDeviceEndpoint* ep = &USB->DEVICE.DeviceEndpoint[epnum];
// A setup token can occur immediately after an OUT STATUS packet.
if (epnum == 0 && dir == 0 && buffer == NULL) {
buffer = control_out_buffer;
}
bank->ADDR.reg = (uint32_t) buffer;
if ( dir == TUSB_DIR_OUT )
it may be fast enough not to
yup
or its a detail of the periph
if the transfer complete interrupt for the previous zero length transaction is fast enough to beat the next setup it'll work
probably why it works with arch
ubuntu gives us 60 microseconds
let me check arch
tulip sleet
no /dev/ttyACM0?
slender iron
that could be a separate issue
tulip sleet
works for me on my ubuntu box and on windows (though I had to unplug/replug - the first time it said "not recognized device", but that might have been left over from the previous failures
slender iron
ok, my arch box is slow about it. it has a start of frame before the next setup
solar whale
cool ! seems to be good -- I'll try adalogger
slender iron
mac gives 250 microseconds or so
k I'm gonna go for a run. will PR this after
gotta untangle it all
thanks for the testing!

bit of a confusing time I'm having with loops in circuitpython. I have a function which takes in a 2d array and performs an XOR on it and another value. It doesn't look like the array is printing correctly
"""Performs AES Round Key Step
"""
for col in range(0, 4):
for row in range(0, 4):
print(state[row][col])```I'm probably iterating/printing it incorrectly, but what's printed doesn't match the initial state array
printed output:
66 99 99 99 99 99 99 99 93 99 99 99 124 99 99 99```
gusty kiln
so you're just looking to print each column in order?
meager fog
@tidal kiln https://www.adafruit.com/product/4028
can you go to the related learn guides and add this as a featured product
idle owl
@meager fog Nicely done! Great idea, @tidal kiln
meager fog
or kattni if ya are in a spot to do it
solar whale
you are iterating over row first so it walks down the column
meager fog
essentials, itsy m4 guide, anything else you can think of ๐
idle owl
Ok sure
tidal kiln
@meager fog awesome. that_was_fast.gif
solar whale
@prime flower since row is your inner loop it increments first -- down the column
meager fog
@tidal kiln :zoom: we had eveything stocked - the baggie of parts is from another kit
tidal kiln
@idle owl yah - if you can update guides, that'd be awesome, thanks!
idle owl
@tidal kiln help me think of them and I'll get it added to them
steep moth
@tidal kiln The PWM on the ItsyBitsy M4 Express is working beautifully! Thank you for the help, also thank you Adafruit team for fixing the issue. Hmm... I think I might go mess with Circuit Python, maybe do some audio stuff. Have a great day everyone.
tidal kiln
@idle owl CP essentials for sure. but also maybe Itsy M4 guide and CP welcome?
@steep moth i was only a messenger, didn't do the work. but glad it's working. there was also a related DAC resolution issue that got fixed.
idle owl
@tidal kiln the welcome guide doesn't have any hardware on it.
prime flower
@solar whale how would that differ from iterating thru a nested loop in c++, though? Are lists handled differently?
idle owl
@meager fog it's not showing up in the featured products thing.
meager fog
it may take a bit for it to appear live since it just went in the store
but you can add it
solar whale
@prime flower it doesnt but the innner loop increments first so you are holding col fixed and incrementing row -- (so you are printing each column)
idle owl
I mean it's not showing up for me to add. I'll add it to my list to do this and I'll check back on it in a bit.
meager fog
ok yeah it takes a few mins
idle owl
I'm too quick!
solar whale
col 0 row 0, col0 row1, col0 row2 ....
tidal kiln
@idle owl ok. just essentials and itsy m4.
prime flower
@solar whale thanks! got it past a full AES round 1

Does anyone know if the Requests package will be ported to CircuitPython? I tried a manual install via upip and ran into all kinds of issues. Tried to reflash and try a few different techniques, but alas my skills are lacking. ๐ I also tried a manual port from MicroPython and this seemed to have less errors, but still no luck.
slender iron
@bold plaza ya, I'd like to have it at some point soon. I've been up to my eyeballs in USB lately though
bold plaza
@slender iron Oh exciting! I'm more of a hardware guy personally, I've tried to look into USB protocols before.. talk about a headache. Hard pass for me! ๐ I'll give the port another go over the weekend and see what kind of results I have.

obsidian dome
Is there a way to extract the pin info for an object? For example, I create a digitalio item and pass board.D13 to the constructor. Any way to re-discover that later?
gusty kiln
@obsidian dome there's a _pin attribute. i'm not sure if there's a better way to get at that.
tulip sleet
@prime flower could do:
print(state)
will just print the whole thing. If you really want to iterate:
for row in state:
for val in row:
print(val)
I got neopixels working on raspi by installing rpi_ws281x and adafruit_blinka and running the code as root. . The problem was -- Can't open /dev/mem: Permission denied - so I needed to run the application as root????
obsidian dome
Hmm. consider 'led=DigitalInOut(board.D13) led.direction=Direction.OUTPUT' when I ask for 'print(dir(led))'
I get '['deinit', 'enter', 'exit', 'switch_to_output', 'switch_to_input', 'direction', 'value', 'drive_mode', 'pull']' What am I missing?
slender iron
@obsidian dome in circuitpython its a c object so it won't have a _pin attribute exposed
bold plaza
Sorry for the delay, work atm. @slender iron Yes I'm working with the Huzzah Feather atm, but have a few other MicroPython capable boards as well. (ESP32-WROOM and the STM32F4 variant)
slender iron
@solar whale you around? I may have nrf fixed
solar whale
yes
obsidian dome
@slender iron I intuit this means that there is no way to find the pin for the object.

minor issue when I try sometjing I have done before -- using SPI -- get "SCK in use" but I can mount SDCArd OK
slender iron
k, that sounds different
slender iron

I can run my "paint" demo on TFT using code on the SDCard!!
has mu ever seen a 52832?
I never tried it.
still no control-C -- can't interrupt a running script on 52832 -- not a new problem!

The hallowing eyes are in Aduino?
solar atlas
Ahh, thought the hallowings came with CP on them.

Travis is failing it: https://travis-ci.org/adafruit/circuitpython/jobs/454787830
tulip sleet
it used to download an alpha version of sd140 v6.0.0, which has disappared. I'm fixing it but the directory names are a bit wrong
I think I made a typo somewhere
did 3.x ever actually work on pca10056? Is this sort of pointless?
raven canopy
i was just thinking about that. did the pca build sneak in during early switch to 4.x?
solar whale
I do't recall -- ddi travis cahnge the path fpr downlaoding the bluetooth sd drivers -- it channged recently
I don't see any reason for pca10056 on 3.x
tulip sleet
the alpha version disappeared from the nordic website. I have it downloading now. just some .mk issue about "nrf52" vs "nrf52840" in a directory name.
tulip sleet
I don't need to delete it. I just need to fix a little thing.

@idle owl Saw you on the Show and Tell that you are working on CP library for LCD text displays. Is that the I2C backpack ones? I have a bunch of 4x20 mono LCD text displays (generic - import...) that I had the toughest time trying to find the library that worked in Arduino. The configuration pin settings were also different. #define BACKLIGHT_PIN (3) #define LED_ADDR (0x27) // might need to be 0x3F, if 0x27 doesn't work LiquidCrystal_I2C lcd(LED_ADDR, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE) ; This worked for me with the fmalpartida Liquid Crystal library. When using these displays, because it is based on old hardware - the display is "interlaced" with first line that spills over into the third. The second line spills over into the fourth. Just wanted to mention it if helps to make a "universal" library for other than what is the specific Adafruit product(really so I can reuse these displays with CPX). Thanks.
manic glacierBOT
tulip sleet
@raven canopy this is a mess - I fixed my directory problem, but the alpha download disappared, and the API has changed so that the 52840 code no longer compiles. Not sure it's worth fixing. I think maybe we should just remove the pca10056 build
raven canopy
in my lowly opinion, i think removing is the better option too. 3.x doesn't "officially" support nRF52 right? almost seems to invite confusion/quesitons.
i can remove it from the .travis.yml in my PR...seems easy enough.
tulip sleet
I need to see whether a patch is needed in download_ble_stack as well. hold on.
raven canopy
holding
tulip sleet
Try just commenting it out it in tools/adafruit_build_bins.sh.
i think the error in download_ble_stack.sh is ignored.
raven canopy
@tulip sleet i just removed pca10056 from the ATMEL_BOARDS definition, and left the conditional in there. we'll see how it turns out. Travis is creeping right now...

That is, with a Circuit Playground Crickit.

@candid stump I haven't heard of that before

Anyone against me releasing alpha.3 today?

The delayed REPL on the nRF boards is odd, but if it shows up eventually, that's good. That may be the ampy problem? Could you add a caveat that the bleio API will change?
slender iron
what do you mean by delayed repl? is there an issue for it?
tulip sleet
slender iron
@solar whale is the repl delay apparent on the 10056 too?
it could be the internal flash write on the 59

dawn rampart
Would it be possible to create a new feature to run storage.erase_filesystem() via a 5s long press of the reset button?
tulip sleet
i'll test on the 10059 now
dawn rampart
I keep inadvertently getting corrupt code.py files and have to then log into REPL and reset things. Not a huge deal, but would be neat if I could do the same thing with a long RESET press.
slender iron
@dawn rampart no, we can't time the reset push because it stops the cpu
dawn rampart
ah
tulip sleet
@dawn rampart how are you editing the files, and what OS is it?
dawn rampart
I edit with notepad++ typically. Windows 10 normally, but I also use Mac. It is totally my fault. Usually it is a terrible bit of code, or I don't give it time to properly reload itself or I'm messing with the board and I have, unfortunately, placed a 3v3 pin next to the reset pin. Every now and then, during file upload, they short.
Or unshort?
REPL always saves me though. ๐
tulip sleet
notepad++ does not force-write all the data at once to the filesystem. There are other editors that do. See https://learn.adafruit.com/welcome-to-circuitpython/creating-and-editing-code#1-use-an-editor-that-writes-out-the-file-completely-when-you-save-it-6-13

Ah - RTM! I will switch to something else. I have Mu installed, might as well use it. ๐
tulip sleet
Mu is a great choice if it's not too minimal for you.
also it makes it really easy to get to the repl, as you know
dawn rampart
Actually, I've never gotten Mu to connect to the serial port correctly. Always tells me it cannot find an attached device - because it doesn't know to look for my Mini SAM M4 board. So, I use Putty
I was going to checkout Mu on github and look about adding my board to a special build just for myself, but Putty is fine.
@tulip sleet and @slender iron - FYI you two have been super helpful. I've got a couple extra Mini SAM M4 boards I could send you if you are interested.

idle owl
@cunning trail I'm not certain how I could integrate those changes into the lib. I don't have any way of testing it and we would then be responsible for supporting it. The changes I'm making are to redo the library to make it use an existing IO expander driver and breaking out the shift register into it's own library. There are no functional changes to how the backpack works. I've also added the shield.
cunning trail
@idle owl Thanks. It is worth it to get only vetted and supported products from Adafruit.
idle owl
@cunning trail The library handles all the pinouts in the background because they're determined by the hardware, so it isn't something you can set without modifying the library I think.
Well, you've got older hardware sitting around, it happens ๐
cunning trail
Yeah, the end user expectation is that you should just be able to plug in a few numbers and it should work. I know it is more complicated than that.
slender iron
@tulip sleet want to merge the path swap into master before alpha.3?

@slender iron To answer your earlier question, I agree we should do alpha3.
inland tusk
@slender iron @idle owl I talked to modern device today and they are sending me a fluxamasynth for raspberry pi and Feather. This also includes a python library too.
I am going to try to adapt the python library for CP.
slender iron
@inland tusk awesome!
tidal kiln
@idle owl is it possible to rename a library repo without pulling a thread of general mayhem?
idle owl
@tidal kiln Not exactly. What do you need to rename?
Is it an existing library? Or something new and not used yet?
tidal kiln
seems like it should live there, maybe rename it to TMP00x or with 3 x's which the spam bot loves.
idle owl
So.... I think my suggestion would be to create the Adafruit_CircuitPython_TMP00x or whatever you want to call it, incorporate both into it, and then we archive the TMP007 in favor of the new one. I feel like that would end up being less work if indeed it makes sense for them to be together. It means we wouldn't have to go back and find all the places it needs to be changed, we would get it all right from the beginning and then only have to deal with guide code linking to the examples and so on.
Because sooooo many things would need to be changed.
thinks
Docs, doc links, Readme URLs, setup.py, PyPI, guide code, example code...
I'm sure I'm forgetting something.
If you created it new, we could start from the bottom-up instead of top-down.
I guess I'd get verification on that though from Limor before that's the route you take. But I really feel like that would end up being less work in the long run.
Are there other TMPx sensors?
tidal kiln
not right now, at least not in shop - just 6 and 7, and 6 is no longer made
but we've kind of orphaned it library wise
shouldn't be too hard to use the 7 driver and add one for 6
idle owl
Right
tidal kiln
so it does sound like this pulls a thread, kind of what i thought
tidal kiln
how about just putting it in that repo and not worrying about a rename
at least for now
idle owl
hmm....
I'm not sure it makes sense that way.
I mean it's a less destructive way to do it, but it ends up confusing because the lib name doesn't match
tidal kiln
or.....just make a totally new repo
idle owl
That would be the least confusing, nondestructive way to do it. But I understand you wanting them combined as well.
tidal kiln
your call, since i'd need your help with any fall out, whichever route you think best
idle owl
Creating a new repo is the least amount of work. And now that I think about it, if it's not made anymore, we'll eventually stop supporting it, and having its own repo means that's easier than having to extract it from a combo lib. So I think create a new repo for it.
tidal kiln
ok

@tulip sleet did you try the slow REPL check on your mac as well? is it just Ubuntu?

danh do you generally overwrite an Arduino IDE (they are up to 1.8.7 now) or do you wipe the old one and start new, for a pristine installation of the IDE?
tulip sleet
on Ubuntu, I just unzip it and move my symbolic link to point to it. On Windows, I install it, which uninstalls the old one first. I don't remove the .arduino15 or Arduino15 directories -- that's what sometimes gets messed up (usually on a board update)
~/.arduino15 or Arduino15 in AppData somewhere on Windows
timber mango
Thanks, danh. I'll try a symbolic link. Sounds like that'd be useful in the future.
(Debian Linux AMD64 here)
hah I was already using one. ;)
This thing has a setup shell script specifically for linux, and does a lot of stuff we address elsewhere, such as sudo apt-get -y remove modemmanager
I think I saw something for udev rules in there as well.
Since it says it needs root, I have never run this script. ;)
/local/path/arduino-1.8.7/arduino-linux-setup.sh
tulip sleet
@timber mango hmm, I don't think I ever ran that. Maybe we should add it to the Learn Guides. Fixes a lot of potential problems.
timber mango
~/.arduino15 is instantiated as a new directory (when missing) the first time a newly-installed Arduino IDE is launched in Debian (AMD64).
It is only populated with preferences.txt.
This is upon examination, after a successful compile of a new (almost empty; default) sketch for the Uno (the default target board).

@pastel panther do you have a link for your CP32? I'm adding it to the release notes
tulip sleet
@slender iron in general, do you think shared-bindings routines should do arg validation, or leave it to common-hal, or should both, or should common-hal assume validation (when it's safe). E.g., I'm checking an int arg to make sure its <= 0xffff, so who checks?
slender iron
shared-bindings should if its a universal constraint
common-hal can do more if the implementation is more limited
tulip sleet
it's universal, but can common-hal then assume that it's passed validated args?
I can add that to a comment for the routine
slender iron

@slender iron I don't know if you remember I was working on a touchscreen project with Circuit Python, and you were doing some updates to the drivers for the 2.4ยจ TFT Featherwing.
Anyway, Iยดm back to electronics on the project (our timeline completely changed), and I'm wondering if the Circuit Python drivers support 8-Bit Mode, or only SPI (which is what I was using before)

@red dock only SPI so far. I got very sidetracked into audio and usb since then.

I'm trying to use a SSD1306 OLED display on RaspberryPi with CircuitPython, but getting "no framebuf module found" error. Opened an issue https://github.com/adafruit/Adafruit_CircuitPython_SSD1306/issues/12, but maybe someone here can give a quick advise?
umbral dagger
@hoary hill What version of CircuitPython?
umbral dagger
@hoary hill The display system is in flux as of 4.0 alpha 2. I haven't tried alpha 3 yet. For my SSD1306 builds I stick with 4.0 alpha 1 or the latest 3.x.
hoary hill
@umbral dagger How do I check which curcuitpython version I'm using? Just installed Blinka using pip3 install adafruit-blinka
umbral dagger
Oh.. with blinka.. right. I haven't started playing with that yet. This is the place to ask, though. It's still early in some places, so the right folks might not show up for a bit.
solar whale
@hoary hill to check the installed pip3 modules do pip3 list -- you can also do pip3 search adafruit to see all the available modules and if you have the latest
you are not actually running CircuitPython on the Raspberry Pi so there is no "version" -- just a version for each module.
umbral dagger
@solar whale What's the displayio situation with blinka. The issue sounds identical to what I see with CP 4.0 alpha 2. (missing framebuffer)
solar whale
@hoary hill -- I just posted some info to your github issue https://github.com/adafruit/Adafruit_CircuitPython_SSD1306/issues/12
@umbral dagger as far as I know dispayio is on;y working for graphics (no text) on the hallowing.. the rest is WIP.... you can use bitmapfont with the OLED as posted to the issue..
also framebuf was removed from the 4.x CP builds ๐ฆ so bitmapfont is the only way now -- unless you make a custom build and put framebuf back in.
marble hornet
could blinka be installed on a rpi compute module?
solar whale
@marble hornet no idea -- I have never worked with a compute module.
marble hornet
Is cp faster on
solar whale
if you mean on a Raspberry Pi with Blinka, it does seem to run faster than on an M0 for example. I have not doe much testing, but the neopixel color wheel updates a lot faster in an RPi 3B+ that on an M0. Not too surprising!

@tidal kiln I'm really puzzled by the issue with the SPI on the RPi -- I wonder if it is something to do with multithreading on the Pi 3. The use of a shared buffer seems suspicious.
@hoary hill -- did you make any progress using the OLED on your Pi
tidal kiln
@solar whale oh wow that threads seen some action....need to read/catch up....
solar whale
been a busy morning ....
tidal kiln
@solar whale which shared buffer?
tidal kiln
beat me to link. yah. and it's a class level buffer. hmmmmm......
solar whale
just wondering if the Pi is too clever....
tidal kiln
but the python code isn't doing any multithreading. so it should be ok.
solar whale
true -- something very odd going on. Without the sensor its really hard to guess.
how does reading from the radio cause only the accel data to freeze..... it is more SPI tranactions
tidal kiln
i've got an LSM9DS1, but not the radio breakout, so also can't test
yah, not sure why that would matter. spidevice makes sure only one thing uses the bus. and the entire python session will get context switched out, but the code itself should never be trying to deal with more than one of the spi transactions at a time.
i think if it were something to do with rpi multithreading, we would be seeing similar issues all over the place
solar whale
I'll think about getting one -- won't be able get to it until after Thanksgiving - I'll be on the road. It'd be fun to understand . Perhaps the OP can poke at the driver and learn something.
I can slo look at other sensors I have to see if there are similar ones -- The LIS3DH works great, but it is just one sensor.

marble hornet
@solar whale thanks
lunar scroll
@red dock The IM pins are "interface mode". Various combinations configure the driver to use different interface modes. 0 open and 1,2,3 closed mean 4-wire SPI.
hoary hill
@solar whale Thanks a lot, it works now - just a matter of copying the framebuf.py, as you advised on GitHub issue!
solar whale
Great -- as Ladyada warned, it is unsupported at this time, but it does seem to work.... good luck!
tulip sleet
@slender iron is the idea not to do any computation in shared-bindings? I take a string UUID and parse it to binary in shared-bindings, and then pass it to a common-hal routine. But I could factor out the parsing into a shared-module routine. ... Also the naming of routines in shared-module is all over the map: sometimes shared_module_blah_blah, sometimes common_hal_blah_blah, sometimes thing_module_blah. not sure if it matters
slender iron
just a moment, on the phone
tulip sleet
np
slender iron
@tulip sleet shared-bindings should theoretically remove all the python stuff from the api and interface with a pure C layer
I use the common_hal prefix if it may be implemented in a port specific way
shared_module would always be shared and neither is internal to the supervisor usually
so, I think its fine to parse the uuid in shared-bindings
tulip sleet
ok, sounds good this is an unusual case, yes, I think it's the first more heavy-duty arg conversion, but it's still arg conversion. there was some leakage of common-hal bleio stuff (access into the common-hal objects) into shared-bindings and shared-module also, fixing that. Tnx!

That NeoTrellisM4 library for Arduino is b0rked. I have an older copy that compiles. Current one does not.
Unless I'm just too confused. ;) (possible)
The good one is severely truncated in this file:
Adafruit_NeoTrellisM4.cpp
which confuses me. ;)
I think the boolean is unsupported by the .. library?
Should be easily reproduce-able -- just erase (hide) any version of this that you already have, and load the current version from github (~/Arduino/libraries). Compile in that folder's examples.
Should break easily (try the 16 synth one).
timber mango
I can't even construct a theory as to how this got into the code:
trellisKeypad.clear();
(from https://github.com/adafruit/Adafruit_NeoTrellisM4/blob/master/Adafruit_NeoTrellisM4.cpp#L28)
$ ag clear
$ pwd | cut -b11-99
s/Arduino/libraries/Adafruit_Keypad
The only thing I can think of is that the developer has a private Adafruit_Keypad lib. That would fit the facts, I think.

no worries - whenever you can get to it. yah - not sure an eraser would help since it seems to be freezing up on the copy over
tulip sleet
another question is can they still load Arduino programs? Like, can they load Blink multiple times, varying the blink rate a bit to make sure a new version is uploaded
we could make a blink.uf2 from an Arduino-loaded Feather by dragging CURRENT.UF2 off, and they could try loading that.
tidal kiln
i've asked. they seem to indicate it still works with arduino, but its worded weirdly.
tulip sleet
@tidal kiln thinking about this some more, it would be worth seeing if it works with Arduino now, as opposed to "it worked before". I'm wondering if the bootloader was damaged in some way. The Feather M4's have unprotected bootloaders, which should be updated to protect them.
idle owl
I have no idea if I did it right but I managed to get most of CharLCD into properties and it seems to work.
idle owl
Oh. I didn't see you had said anything until you called show. Thanks!
No idea what to do with this: ```python
def create_char(self, location, pattern):
"""
Fill one of the first 8 CGRAM locations with custom characters.
The location parameter should be between 0 and 7 and pattern should
provide an array of 8 bytes containing the pattern. E.g. you can easily
design your custom character at http://www.quinapalus.com/hd44780udg.html
To show your custom character use eg. lcd.message = "\x01"
:param location: integer in range(8) to store the created character
:param ~bytes pattern: len(8) describes created character
"""
# only position 0..7 are allowed
location &= 0x7
self._write8(_LCD_SETCGRAMADDR | (location << 3))
for i in range(8):
self._write8(pattern[i], char_mode=True)
an X is easy to create a custom glyph for -- or a square box the size of the character cell
idle owl
I am referring to whether or not to move it into a @property in the library.
tidal kiln
would need to read the datasheet to learn more about what those "CGRAM locations" are all about
idle owl
Yeah....
About that.
@tidal kiln Almost all of my @propertys have setters. is that normal?
tidal kiln
probably
idle owl
Ok
tidal kiln
being able to read and write is probably most common
idle owl
Then maybe I managed to do this right.
tidal kiln
so you'd need both
every now and then you want something to be read-only
so no setter
idle owl
ok
tidal kiln
in C++ land, these end up being getFoo() and setFoo(), the so called getter / setter funcs
so common, most IDEs have macros or hot keys to auto generate them
idle owl
basically anything that had a bar in terms of def foo(self, bar): ended up being the setter...
with an associated @property.. I dunno. It works. doesn't mean I did it right.
Still need to update examples and doc strings.
tidal kiln
"right" can be pretty subjective here, so don't worry about it too much
idle owl
Fair enough.
tidal kiln
this is the kind of stuff you learn by getting something to work, putting it out there, and getting feedback on it

I expect a lot of that.
tidal kiln

Why does circuitpython use the 1k oscillator and arduino use the 32k?

balmy night
I'm willing to help diagnose further if it helps everyone else out in the future. Otherwise, if you'd simply prefer me to "install it and move on", I'll do that as well.
tidal kiln
yah. seems to be model related.
on a Pi 3B+
Successfully installed Adafruit-GPIO-1.0.3 adafruit-blinka-0.2.7 adafruit-pureio-0.2.3 rpi-ws281x-4.0.0 spidev-3.2
on a Pi Zero W
Successfully installed Adafruit-GPIO-1.0.3 adafruit-blinka-0.2.7 adafruit-pureio-0.2.3 spidev-3.2
Ok, so that means it's normal, or there's a bug somewhere?
tidal kiln
@balmy night dunno. for now, try just manually installing that package and see if that gets you working.
balmy night
FWIW, I poked around at the rpi_ws281x git repo I cloned a bit further, and it does seem like it -does- work (the "test" application that repo builds using 'scons' does indeed light up my pixels.)
tidal kiln
@idle owl any ideas?
idle owl
Nope, nothing more than I already came up with.
balmy night
And, confirmed. After manually installing the library, strandtest is now operating correctly!
balmy night
@idle owl I โค โค โค that emoticon. It's my fav ever! ๐
idle owl
But if it's working on 0W, then maybe we need to change that limiter
tidal kiln
maybe. not sure why it's there though. i haven't done a ton of this pi/neopixel stuff.
balmy night
Carter, kattni, thank you two very much for your help! I greatly appreciate it! If you don't need me at this point, I'll step out..
tidal kiln
nah. all good. happy to help. glad it's working. have fun!
balmy night
Definitely will! Many thanks again!
idle owl
@balmy night Have a good one! Happy NeoPixeling!
@tidal kiln You could file an issue on NeoPixel and tag Brennen and I, and maybe Ladyada to find out what's going on with that.
tidal kiln
neopixel or blinka?
idle owl
oh wait. The limiter is on Blinka.?
tidal kiln
appears so.
idle owl
Mmm.... hmm.
NeoPixel with a reference to that line maybe?
Whatever you think makes the most sense is probably fine
tidal kiln
no worries. i can bring this up via an email channel. want me to cc you?
idle owl
Yeah please
Re CharLCD. There's left_to_right and right_to_leftwhich displays the text in the indicated manner. Would you expect if you set them to False that it would do the opposite one?
I feel like maybe it should. And I think keeping both makes sense because it means someone who is defaulting to right_to_left can use only that to change their text direction, versus only having one that does both behaviors.
tidal kiln
how about...?
have a direction property you set with class level consts LEFT_TO_RIGHT or RIGHT_TO_LEFT:
char.direction = char.LEFT_TO_RIGHT
or text_direction or some such
idle owl
um.
maybe
except that there's weird stuff that goes into setting it LTR or RTL.
not sure how to assign that to a constant.
I guess leave the setter as a function and assign the getter to a constant
?
tidal kiln
the consts wouldn't be the actual values, just enum like - so 0,1,2, whatever
they would get used in conditionals in the direction setter
idle owl
um.
tidal kiln
@direction_setter
def direction(self, value):
if value == self.LEFT_TO_RIGHT:
# blah blah
elif value == self.RIGHT_TO_LEFT:
# other blah blah
oh.
tidal kiln
idle owl
Correct.
It does not work currently.
It works in mine.
But not, apparently, in the best manner.
tidal kiln
@direction_setter
def direction(self, value):
if value == self.LEFT_TO_RIGHT:
self.set_left_to_right()
elif value == self.RIGHT_TO_LEFT:
self.set_right_to_left()
Ok that's basically what I was saying earlier.
tidal kiln
but with consts instead of boolean
tidal kiln
are there only the two options?
idle owl
For that, yes.
tidal kiln
so maybe you could treat it like a backwards or reversed flag, and then just set it with a boolean
char.reversed = True
I like that even less. Because then we're assuming that "left to right" is the "forward" way of doing it and that doesn't feel right towards people whose text defaults right to left.
tidal kiln
yep. it does make that assumption. so then back to the other approach.
idle owl
where do I initialise class level constants.
tidal kiln
class Foo:
SOME_FOO = 42
Do I make them None ?
idle owl
...
tidal kiln
class Foo:
LEFT_TO_RIGHT = const(0)
RIGHT_TO_LEFT = const(1)
lime trellis
hi is there a way to poll the state of a MISO pin after creating an SPI class?
(not clocking out data, just seeing if MISO is being pulled one way or another)
tidal kiln
they need to have unique values for using in conditionals
stuck elbow
@lime trellis not with the hardware SPI
@lime trellis you would need to deinit spi, create DigitalIO, check it, deinit it and the re-create the SPI
lime trellis
darn... but I see what you mean
stuck elbow
software spi doesn't care, of course
though I'm not sure if there are some locks in the implementation we have
solar whale
@idle owl I just made a minor update to the RFM69 library -- it's been merged, but do ai still need to do a release manually or is that all automated now?
idle owl
@solar whale Always release. The bundle update is automated, releases are not.
solar whale
OK -- I'll do it now.
stuck elbow
@lime trellis no idea, sorry, not even sure if there is software spi implemented
solar whale
@idle owl are these normal at the end of the travis run i it was green ```Skipping a deployment with the releases provider because this is not a tagged commit
Skipping a deployment with the pypi provider because this is not a tagged commit
roger. thank you @stuck elbow !
solar whale
ah -- nevermind -- it took awhile for all the files to show up in the release -- I think it's all good.
I was looking at the wrong Travis run.
pearl cradle
Is this the right place to ask questions about issues I am having with circuit python ?
exotic pumice
yes
pearl cradle
Awesome. So I am trying to use the BME280 I2C sensor with a Rasberry pi zero. I can see the device on address 77 with I2C detect on bus 0 (i2cdetect -y 0) but when I try to use the busio.scan method it is returning null
I am using the sample code found here https://circuitpython.readthedocs.io/en/latest/shared-bindings/busio/__init__.html
exotic pumice
it looks like address 0x77 is the last one. Maybe there's some kind of off by one error?
Just guessing
pearl cradle
Idk, Even when I work with the library that connects to the device it cannot find anything on address 0x77 I've spent about a day trying to figure this out. The only thing I can seem to figure out is when I check bus 0 (i2cdetect -y 0) it can find the device no problem but when I try bus 1 it cannot find it (i2cdetect -y 1)
tidal kiln
@pearl cradle which pins are you attaching to on the Pi?
pearl cradle
GPIO 30&31 (pins 27&28). I cannot get the device to be recognized at all on GPIO 8&9 (pins 3&5)
tidal kiln
you should use pins 3/5, the other bus is considered reserved to reading HAT EEPROMs
and those are the pins being used by board.SDA and board.SCL
but it's weird that you can't see the device if you wire there and run i2cdetect -y 1
pearl cradle
Is it possible that it is either 1) an issue with rpi zero w 2) there is a bad trace on my pi?
Youll have to forgive me if I seem ignorant when it comes to the PI, most of my linux/python development has been done on server clusters, so this is a new world for me
tidal kiln
well, not sure. let's verify pins first.
use those
oh wait. this is even better...
same pins. that's just a better diagram to reference.
quasi fjord
isn't i2c bus 1 usually an internal thing for the GPU or similar? So you wouldn't expect to find anything useful on it
tidal kiln
not sure, but /dev/i2c-1 is the device entry used for the above pins
pearl cradle
I am sorry, my power supply to my computer just caught on fire
tidal kiln
๐ฒ
exotic pumice
gotta love that premium apple quality
pearl cradle
Lol
Okay so now that the crisis has been averted Iโm back to the PI. I have rewired the sensor on pins 3&4
exotic pumice
3&5?
tidal kiln
can you post a photo showing how you are wiring this up
pearl cradle
The header on my power line looks bad but it is fine Iโve tested it multiple times
tidal kiln
sensor is the BME280?
https://www.adafruit.com/product/2652
pearl cradle
Yes, itโs not the adafruit one. Itโs one that is compatible and Iโve used this same sensor with an arduino
tidal kiln
the BME280 can be either I@C or SPI, are you sure this breakout is I2C?
pearl cradle
Yes. I used it with an arduino using I2c no problem
tidal kiln
@idle owl just FYI: https://github.com/adafruit/Adafruit_Blinka/issues/45 (TLDR = brennen's on it)
solar whale
it looks like you r SDA is off by a pin on the bme280 -- SDA <-> SDI on the BME 280
oops -- I see it is not the adafruit breakout -- sorry
tidal kiln
it's....nvm. that.
@pearl cradle post a photo of front of sensor, or link to info page if there is one
solar whale
I just tried a bme280 on an RPi 3B+ -- at first it did not see it but after reseating it, it works fine.
also I see there is a recent upgrade to the lib -- should be at 2.2.0
tidal kiln
@solar whale so it shows up as expected with an i2cdetect ?
solar whale
now it does -- after reseating the board ๐
I hve the board plugged into a breadboard
tidal kiln
ok. just wanted to make sure it wasn't some odd ball sensor that didn't report back during the scan or something.
solar whale
what kind of sensor would do that ๐
pearl cradle
tidal kiln
pi GPIO header pins soldered on good?
marble hornet
is the input to RunMode a string? i looked at the docs, it doesn't say.
https://circuitpython.readthedocs.io/en/3.x/shared-bindings/microcontroller/__init__.html?highlight=RunMode
tidal kiln
soldering on breakout looks excellent
marble hornet
nor the runmode page
solar whale
good luck with the bme280 -- not much else I can add.
tidal kiln
@pearl cradle what's the voltage on the CSB pin?
pearl cradle
tidal kiln
thanks. that's also nicely done.
tidal kiln
that's what it should be
not sure then
try going back to the arduino and make sure the sensor is still OK
alternatively - try another I2C device on the Pi
pearl cradle
Allow me to check
solar whale
is that a pi zero or zero-w?
pearl cradle
ZeroW
solar whale
ok - I haveone handy -- I'll try mine on it.

Iโm thinking itโs a bad board maybe I burnt a trace when I soldered to it
solar whale
wish I could be of more help -- good luck!
pearl cradle
I appreciate it
After reflowing the gpio pins nothing. I donโt have another i2c device to test these pins with so Iโm gonna say the pins on the board are bad. Is there a way I can test the pins to see if they are in fact dead
solar whale
If you have an oscilloscope or logic analyzer you could look at the pin activity.
pearl cradle
Does this look right?
Lol just kidding I plugged into the other pins and Iโm only measuring a peak to peak of 0.1v no connect. 3.3 v when running i2c detect

Is anyone looking into (or working on) supporting the PJRC Teensy3 audio lib in CircuitPython? It's been ported to the SAMD51 (see the synth example in the NeoTrellisM4 C++ lib). I could really use it for a project I'm looking into doing. ๐
slender iron
@umbral dagger I glanced at it. It relies on static constuction of objects which circuitpython is bad at
umbral dagger
@slender iron OK, maybe (hopefully) Iโm missing something with audio. I want to play a logish file, looping, in the background, and play short clips on top of it.
slender iron
@umbral dagger thats why I added mixer
umbral dagger
@slender iron So I was missing something... excellent!
marble hornet
I would never have been able to progress my project so far if it hadn't been in the wonderful language I was taught in school. I owe all fo you a HUGE hug. Meeting or not: Thank You.

Anyone know why i can no longer import adafruit_dotstar in circuitpython 3.1.1 on a ItsyBitsy M0? Seems odd since there is one on the board.
Ah! It looks like I have to drag it onto the flash drive from the "bundle" zip file
marble hornet
is there anyone way to unimport the text file that is brought in from flash when import it called?
cedar beacon
I've started writing a guide on using Circuitpython board from home-assistant. The idea is to enable projects using circuitpython boards for gathering data (in my case air quality data), and then using home-assistant to both provide an IDE and the means for plotting data saved to a .csv file on the board, as well as a route for posting data to other services (e.g national air quality database). Im keen to hear from any other home-assistant/circuitpython users who might be interested in collaborating on this https://github.com/robmarkcole/circuitpython-on-home-assistant
charred blaze
Im going to attempt to learn CircuitPython and Port over an arduino sketch all at the same time. Any recommendations?
umbral dagger
@charred blaze Do you know Python?
charred blaze
Not yet.
I was looking over a bit of code from Noe's lightsaber and a couple other things, it doesnt look too difficult
umbral dagger
@charred blaze So there's that. Personally, I'd recccoment getting familiar with Python by itself first. Then https://learn.adafruit.com/arduino-to-circuitpython might be useful.
charred blaze
Alright! thank you for that Dastels!
umbral dagger
@charred blaze My CircuitPython 101 series of guides will likely be useful as you get familair with Python.
charred blaze
Ive got my lightsaber code working on the feather m4 with arduino, minus the fact that FastLED isnt compatible with the Feather M4 just yet. That put the biggest kink in my project.
manic glacierBOT
marble hornet
any suggestions? ^^
charred blaze
Any recommendations for getting button input in CircuitPython? Im not just taking simple single button presses but also double/triple/etc. presses and also button holds.
idle owl
@charred blaze I've done similar using state machines and time.monotonic() but there may be a better way to do it.
stuck elbow
unsolicited laptop sticker idea: "My other computer is a CircuitPlayground"
@charred blaze the gamepad module maybe?
idle owl
@slender iron We fixed the bug causing the NeoTrellis failure, but did we address the issue that the board shuts down and drops USB when all the pixels are turned white? I thought that was hardware related and we were going to try to do something to make it fail more gracefully if that happened... Or did the fix we put in address that as well?
stuck elbow
it doesn't handle the holds, double/triple, etc. -- you will have to do that logic with a state machine, like kattni said, but it does do debouncing for you
charred blaze
Thanks @idle owl and @stuck elbow I'll look into those. I know how to do it on arduino, just gotta figure it out for CP
charred blaze
ok cool
tough flax
Anyone know of a debounce/repeat management library? I keep writing the same for for hid kid and house work
idle owl
@tough flax We're going to be adding one soon.
tough flax
Excellent - who should I coordinate with to help?
manic glacierBOT
umbral dagger
@slender iron How about a voice_playing property/function on Mixer in addition to a playing property?
idle owl
@tough flax That would be @umbral dagger and myself. I believe much of the work is already done, it's simply a matter of getting it into library form.
umbral dagger
@tough flax I have a pretty soldi debounce lib in CP. Check any of my guides that use a rotary encoder (the push switch gets debounced). @idle owl will be discussing adding it as a helper lib in the bundle.
If you look at my recent guide on extending CP, it's one of the examples: I port it to C and make a native module of it. Funny since it was originally ported from an Arduino lib.
@tough flax @idle owl I want to generalize it a bit to be able to take a GPIO pin as well as a lambda (so you can debounce any predicate then).
tough flax
Ok great. Generally I need to debounce a pin shorted to ground or a sip/puff from the pressure sensor crossing a threshold. And then I need logic to handle long presses and repeating after a wait period.
Not all of that has to be in the lib of course ๐
umbral dagger
My debouncer gives rose & fell properties, so you could easily keep track of the timing.
teal thorn
Is the startup LED sequence listed somewhere? My build is getting stuck bright white before the drive appears.
I see a green heartbeat before it goes white.
umbral dagger
@slender iron Looks like Dean is working on the mixer voice support. While I'm thinking abouti it, a "finished playing" callback would be fun to have.
meager fog
@teal thorn https://learn.adafruit.com/welcome-to-circuitpython/troubleshooting#circuitpython-rgb-status-light-18-18
slender iron
@idle owl I'm not planning on doing anything else. I added a turn off command on reset which may help. Ultimately I can't give more power for all the pixels though.
@umbral dagger ya, we can add per voice playing after dean's changes

thanks! I'll look tomorrow
cedar beacon
Whats the recommended approach for saving time series data to a .csv file on a circuit python board?
meager fog
@cedar beacon sd card or internal memory?
cedar beacon
Either is fine, the challenge is that the board doesn't know the current time
meager fog
do you want to incorperate an RTC or dont care for timestamps?
here is how to use an SD card
cedar beacon
I care about the timestamps, I want to import the data for processing in pandas, and also put it into a time series sql data base, to collate data from multiple boards
meager fog
its very easy, you just write the data
if you want an RTC - you'll need a separate chip https://learn.adafruit.com/adafruit-pcf8523-real-time-clock/rtc-with-circuitpython
like that
the easiest way by far is to get a feather M4 then pop an adalogger shieldon top - has both all in one!
a feather m0 may run out of memory ๐ฆ
especially if you have a lot of sensors.
this guide covers datalogging
cedar beacon
Im planning on having the boards battery powered, so I could set the timestamp whilst connected to the board initially
meager fog
as a CSV
honestly - just go with an RTC, you bump it once and it loses power
RTC w/batt means no worries
a few $ will save you hours of re-work
cedar beacon
ok I will try that approach, thanks!
btw have you seen https://esphomelib.com/ my ambition is to do similar but with circuitpython
meager fog
we haven't - looks cool
cedar beacon
my goal is to have home-assistant backend and some support libraries to take care of long term data logging and networking with other services already exposed to home assistant. This should get a lot of the tedious 'plumbing' aspects of projects out of the way, so users can focus on making cool hardware for their home automation projects. Anyways I will post updates on this thread.
meager fog
nice!

Im looking for the latest circuitpython for the raw esp8266, is it the file listed as feather_huzzah? https://github.com/adafruit/circuitpython/releases/tag/3.1.1

<@&356864093652516868> Here is the notes doc for tomorrow: https://docs.google.com/document/d/1pAKcZyeDRtLAdyuhE-By60PNcK8yKcQ-ssx55pVr354/edit?usp=sharing
cedar beacon
Thanks @slender iron are you aware of any guides on getting started with curcuitpython on a raw esp8266 board?
slender iron
no, esp isn't used that often because it doesn't have usb
cedar beacon
can you also clarify that point? the board physically has usb, but you have to wire up separately to use the serial connection?
meager fog
