split ocean
powered it down and now it's using my spoofed time.
gilded cradle
Ok, cool
split ocean
or wait, maybe me trying to spoof "12:00" was a bad test, and that's what it defaults to.
gilded cradle
lol
split ocean
like a VCR
split ocean
yeah, seems that's the case. I need to look closer at the openweather_graphics.py and see where it displays the time. Is this the esp32 deciding?
gilded cradle
I think the esp32 is just grabbing web data whenever CP tells it to
It looks like PyPortal does an import rtc and then sets the rtc via rtc.RTC().datetime = now in the get_local_time() function
split ocean
ah, looks like it there's the 12:00 in the update_time function.
gilded cradle
Yeah, it looks like it's getting the time from time.localtime()
split ocean
oh, sure enough.
gilded cradle
Looks like it would be easiest to create a time.struct_time(), set the rtc with your spoofed time and go from there.
Just use
now = time.struct_time((year, month, mday, hours, minutes, seconds, week_day, year_day, is_dst))
rtc.RTC().datetime = now
and fill in the variables with the spoofed data
week_day is 0-6
is_dst is 0 or 1, etc
split ocean
You just saved me so much time as I was about to dive into what that struct_time() format needed to be :)
gilded cradle
Cool. I did a bunch of struct_time stuff with the RTC featherwing

@pastel panther lemme know if yr around we can looka @ ina
i can fix register and you can test
tulip sleet
@solar whale it can work somtimes, but the fundamental problem needs to be fixed still
solar whale
slideshowsd works on the pyportal 😃 at least this time
pastel panther
@meager fog I'm afk until the afternoon but I can ping you when I get back
I don't wanna block you so either you can give it a go and I can test later or I can hack on it when I get home
meager fog
i think we sorta have to do it in tandem
@pastel panther do you have a rough ETA you'll be around?
i can def start
but i just knooooooooow itll need a tweak from u
pastel panther
Of course. Lemme check the schedule
Should be back around 430 EST, later if the trains don't cooperate, earlier if they do
umbral dagger
That feeling when you're hacking and the code flows smoothly from your mind, out your fingers, and into the editor.
umbral dagger
Haha
sometimes
It's like writing.... dump it on paper as fast as you can... edit later
It also assumes you have the design fleshed out in your head already.
solar whale
@tulip sleet I hope my comments were clear enough -- with pr 1620 using an SPI device after setting up displayio seems to work, but it effectively disables the displayio device
sort of like doing displayio.release_displays()
but I can't get it back with out a hard RESET
stuck elbow
@timber mango I'm a regular tuber
tulip sleet
@solar whale that is helpful - I only tested on a pyportal. I'm pretty sure issue is that the stmpe simple test grabs the bus and never releases it, whereas displayio is better behaved. The simpletest should probably be fixed. Does this make sense to you?
it's not polite to hog the bus
tulip sleet
looking...
solar whale
I'll have to see if the driver support the context manager -- there may be drivers that do not have de_inits ...
tulip sleet
yes, I'm confused about that, the read_data() should be releasing the bus...
_read_register() and _write_register_byte() are using the context manager, but maybe they're running so fast that they lock out the displayio tries. Could you try to put a delay in the read_data() loop?
solar whale
the pyportal does not have an issue with SPI and the esp32
tulip sleet
it uses separate SPI buses to talk to them, I think.
solar whale
ah -- and no easy way to connect an SPI device to it.
Ok -- I'll play with the STMPE driver -- I can also try some other SPI devices.
tulip sleet
actually, pyportal uses an 8-bit bus to talk to the display, not SPI, and ESP and touch have separate SPI buses
so my test on pyportal isn't very interesting
i forgot scott switched to ParallelBus for PyPortal
solar whale
ah -- so not comparable -- I'mm also puzzled why SDCard slideshow does not work with the featherwing
also kills the displayio output
tulip sleet
could also be contention on the SPI bus, or maybe I've made an error in my PR.
solar whale
nah -- that could not be it 😉
tulip sleet
in there, could try a pause after reading the file.
solar whale
ok -- I'll try some tests
tulip sleet
wait, hmm, I'm thinking of a possible error I might have made, that when the display update is called in the background, the SPI bus has been grabbed by the code that displays the image, and that's locking out the background task. I'll take a look soon. I'm in the middle of writing up the release notes for the next beta release.
solar whale
np -- no rush

@tulip sleet a delay in the stmpe610 read loop does work -- the screeen keeps updating the REPL even after control-C out of the program
it's not a great way to run the stmpe610, but it does not hang the display 😉

hmm, no
solar whale
odd -- so far -- just the German Metro_m0
tulip sleet
i get -52 bytes free, quite odd
finished initial draft of release notes, will look at SPI contention now
solar whale
may well be the stmpe610 driver that is misbehaved -- the delay helped a lot.
it get a big buffer of data when touched and does a lot of reads.
I have to go AFK for a bit -- let me know if there is anything you want me to try.
pastel panther
hey @meager fog I'm back online if you have something for me to test
meager fog
heya @pastel panther that was fast
ok yeah lets take a look
for register (plain) you can use "<H" or whatever, right?
pastel panther

I know those feels. Then I don't want to have coffee 'cause I'll be up till 4

pastel panther
I love sweet tea but it's still full of caffeine. Don't let them fool you! With their mint juleps and boiled peanuts!
:non-existant-shifty-eyed-emoji:
that'll do 😒
tulip sleet
@solar whale I'm not sure there's anything wrong with my code, but both the SD library and the SMPTE are good at hogging the SPI bus. The displayio background task can't do much if the python code running is holding on to the bus most of the time.
meager fog
@pastel panther ok i commited a fix for RWBit
pastel panther
ok, let me grab it
tulip sleet
I can try calling the background task as soon as someone frees up the bus, maybe.
i'll set up a slideshow on a featherwing tft and try that
raven canopy
@pastel panther but that's why the sugar is added. to counteract the caffeine! 😜

@meager fog I made a NeoPixel color picker with PyPortal where you set the colors as variables and it makes the buttons the color that it will change the NeoPixels to. it's a bastardised version of your soundboard code.

I guess I missed that part but tbh I was skimming somewhat

once we get button merged you can write it up

pastel panther
welp, I just I know what to watch out for in the future now 🤦
@meager fog works great, thanks!
I also have an api question if you have a sec
pastel panther
which do you prefer:
ina.mode = Mode.SHUTDOWN
ina.mode = Mode.CONTINUOUS
ina.mode = Mode.CONTINUOUS
# or
ina.shutdown()
ina.trigger_measurement()
ina.measure_continuously()
or something else
meager fog
top
idle owl
@meager fog sure i'll see if I can figure it out
meager fog
more exttenadle
pastel panther
I was just thinking because the sensor actually does something when you set the triggered and shutdown modes the later would make more sense
meager fog
yeah you're changing the mode
pastel panther
ya, but changing to triggered actually triggers it. I guess I could explain that in the docs
raven canopy
does it trigger and return? you could break that one out from the other two. non-standardish...but.
solar whale
@tulip sleet so - I guess we need to look at any drivers for SPI and try to make them play nicely. I'm not sure there really is a problem with SDCard in general -- may be with slideshow -- I'll be happy to look into stmpe610 and slideshow to see if I can find where the ise issues are -- clearly stmpe610 can be improved - the delay showed that. I suspect the slideshow issue is something like that as well.
raven canopy
ahh. then, yeah i'd just make a note that it will cause the INA's buffer to change.
tulip sleet
I am trying a feather m4 with tft featherwing. I get an I/O error when trying to use slideshow with it. It can list the files properly but then fails doing OnDiskBitmap
is that what you saw?
@solar whale never mind, that is with master, which I know is broken. need to test with PR 1620
solar whale
I don't get any errors now -- It just seems to hang or run but not display -- in "advance" function in slideshow when I control C out
I am using nrf52840 though, not m4
tulip sleet
I may add some delays various places. The sdcard code uses python to read from the card and locks the SPI bus for a significant amount of time. the problem is compounded becuase OnDiskBitmap is constnatly reading data from the file to display the image, since it can't fit the whole thing in memory. It does read a 4k block at a time, but there are a lot of them in a 230k image
solar whale
I won't be able to do much more until Friday -- then I should have some time to dig int things better. I'll keep up with the issues and discussions until then. Good luck! Let me know if you need any information from me.
pastel panther
@meager fog I'll be offline for a bit but I should be able to wrap this up tonight
I wasn't sure if it re-ran after your lint fix so I started it again. I'll check on it again when I get home and review/merge/release

@raven canopy Gotta build that submarine first 😛
pastel panther
@umbral dagger not sure if this counts but a way to easily keep my local copy of the library bundle up to date with the current release would be amazing
umbral dagger
@pastel panther Should be able to do that with a cron job
Kick off a little python script to fetch, unzip and copy into place.
umbral dagger
@pastel panther But, yeah, that wasn't the sort of thing I was thinking of 😃
pastel panther
@umbral dagger is there a stable url that one could fetch for the latest bundle release? If I can avoid scraping the releases page that would make life a lot easier. I didn't think there was otherwise I would have done something along the lines you suggested
raven canopy
@pastel panther the release page is the only location. other than version changes, the only difference in the filenames is the date. assuming adabot and travis are playing nice; which they've been stable this week after my last fix to the yaml.
easiest way, if i were to do it, is to use the GitHub API to grab the latest release, compare local filename, and download if needed. https://developer.github.com/v3/repos/releases/#get-the-latest-release
tulip sleet
@pastel panther @raven canopy there is : https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases/latest, etc., which redirects
raven canopy
yeah, that works too. just have to scrape the links. the API aids by giving the asset URLs in JSON. 6, or half a dozen. 😄
tulip sleet
you could take apart the redirect URL (just fetch the header with curl and find out the redirect URL) to get the tag, and then use that in the API call
oh, i see it's already in the API, ok nvr mind

crimson ferry
I'm seeing some interesting behavior with web server response headers, not sure where to put the issue. (#1) Somewhere, I don't think it's ESP32SPI but then must be either NINA FW or the depths of CP ... headers not served by the server are inserted back to the client (e.g., 'via': '1.1 vegur') - I see this on evewry GET from any site, but only in CP. (#2) In trying to demo #1, noticed that after pulling a couple of pages from disparate sources (via HEAD), headers from prior sites live on and get presented to the client for subsequent sites.
crimson ferry
Nevermind #1, I think that's just an artifact of having hit worldtimeapi.or first.
solar whale
@crimson ferry This may not be relevant - I am new to "get" -- but some of the examples reset the response to None -- I think this was to avoid some issues early on that may or may not still exist, see https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/master/examples/esp32spi_cheerlights.py#L68
crimson ferry
@solar whale That makes sense. The json/text/content comes back OK, but the headers are crazy... after hitting a couple of sites, you have an incredible set of headers being reported to the client.
gilded cradle
That's good info @crimson ferry. It's possible that the WiFi Manager needs to be updated to clear out old data.
crimson ferry
I just tried at the client level and it doesn't seem to make a difference. The old headers seem to be sticky deeper somewhere. response = None in the app doesn't clear the old ones (headers with same name will be overwritten with new values, but old unique headers still get returned next time.
gilded cradle
But you say the problem only happens in CP?
crimson ferry
As opposed to cURL? Yes. If I fetch microsoft.com before twitter.com for example, I'll have microsoft-specific custom headers in the twitter response.headers
Even with response = None between fetches
gilded cradle
I mean I didn't know if you cooked up something that ran on Arduino. I was just trying to see if it might be the NINA firmware or something on the CP side.
crimson ferry
On my Arduino stuff, I don't think I had the ability to see headers at the time,, so I don't know.
gilded cradle
Perhaps file an issue under the ESP32SPI library and after digging in more, if it is in the firmware we can move the issue over.
@crimson ferry, I forgot to ask what your setup was. Are you running this on PyPortal or with a separate ESP32 in some configuration?
crimson ferry
@gilded cradle PyPortal (I can also test on ItsyBitsy M4 with ESP32Huzzah). CP 4.0.0-beta.3, adafruit-circuitpython-bundle-4.x-mpy-20190307, debug is now on, I can put some example code and output in a Gist or something.

@tough flax Here's a guide page for updating your Feather nRF52840 bootloader so it works better on Windows: https://learn.adafruit.com/introducing-the-adafruit-nrf52840-feather/update-bootloader. It's fresh out of the box so let me know if anything is unclear.
umbral dagger
Still seems to be in the regex use...
On the plus side, C-c is being handled better now. (by better I mean the way I want it to)
tulip sleet
maybe some new pattern chars need to be escaped that didn't used to be??
umbral dagger
quite possibly. It seems confined to recognizing double-quoted strings

@slender iron that padding fix to the CSS really helped the image/cell sizing. much improvement!

I noticed in lib/adafruit_midi.py for control_change() it says controller number must be 0-15. But that's not the case, MIDI accepts controller numbers from 0-127 and the underlying code allows it, too. I've tested it with Apple Pro Logic X and it works fine for controller number > 15. Here's the MIDI 1.0 spec, btw:
https://www.midi.org/specifications-old/item/table-3-control-change-messages-data-bytes-2
It's important in order to handle 14-bit controls. For example, controller 20 is the MSB and controller 52 is the LSB. So by reading an analog input w/ high resolution, we can encode up to 14 bits and transmit over MIDI in two separate packets.
I'm using this on the Grand Central, btw. Wonderful board!
I've opened a github issue for the library, but wanted to post it here in case anybody was playing with MIDI.

@slender iron I like the site 😃 I think it's a great landing point for CircuitPython. The downloads page looks better with the CSS fix as @raven canopy mentioned, but if I could make a suggestion -- I imagine someone who's unfamiliar with things would be overwhelmed with a large unsorted list of boards. It's a lot to scroll through.
I know I'm not that helpful as I don't have a specific solution (I'm not a strong web developer), but I think it needs organization of some sort. Either by brand, or by board line -- with a legend in the top/side hotlinking to that section.
pastel panther
Ya, it could go either "whoooOOoooooo LOOK.AT.ALL.THE.OPTIONS" or
"....lookatalltheoptions"

I don't think it's the worst but it's worth considering
I imagine in the future there will be dropdowns for filtering by brand, processor, etc. I'm biased/old/experienced but I think it's good for now
whaddaya know, it's on the list of todos on the github repo
crimson ferry
First time git user... I'm getting an authentication failure trying to do a git push of a CP library change to my forked repo. I'm sure password is correct... tried "anecdata", private email address, and aliased email address as username.
pastel panther
using keys is suggested (and much easier in the long run):
https://help.github.com/en/articles/adding-a-new-ssh-key-to-your-github-account
raven canopy
@crimson ferry do you have OAuth/tokens set up? ^^^
if you do, you need to use a token for the password.
modern wing
@pastel panther I wasn't even aware there was a list of todos in Github (still kinda new to this). Do you have a link to that page so I can read it before putting my foot in my mouth next time? 😄
pastel panther
Neither was I until I looked!
It's not a github feature or anything, just something someone added to the README
crimson ferry
@raven canopy Not that I know of. I have one unrelated 'Authorized OAuth App', but no GitHub apps. No personal access tokens. I tried both with and without 'Block command line pushes that expose my email' checked. Username 'anecdata' and alias email (xxxxxxxx+anecdata@users.noreply.github.com) is set up in git. I have 2FA.
pastel panther
@crimson ferry are you wedded to using password auth? ssh keys are pretty nice...
crimson ferry
@pastel panther I added a key to GitHub. It's not clear to me how git uses that. It still asked me for username and password.
exotic pumice
@anecdata click ssh next to the clone link
pastel panther
crimson ferry
@pastel panther @exotic pumice Done, but it's still asking for username. I'll scrub it all and start over, maybe a problem with the sequence things were done in. Thaanks.
pastel panther
@crimson ferry I think you may need to set a default username when connecting to github in you ssh configs; what OS are you using?
crimson ferry
macOS
pastel panther
ok; lemee double check my config; it's been a while
raven canopy
on the git side, there is git config --global user.name <username>. not sure if the SSH part makes things different; never used SSH.
main meteor
my ~/.ssh/config has this for my github config: ```
Host github.com
HostName github.com
User git
ya I think github figures out your account from your git email
I think user.name is your name name, not your username
raven canopy
i have both set. git config --global user.email <email>. 🤷
main meteor
If you want to use key-based login, add another entry for your private key to your config file: ```
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa
@modern wing Ya, I agree the list is long. Its currently sorted by the number of downloads per board but only based on 3.x
The search does work
crimson ferry
Thanks, all. I have a few things to try.... 😃
raven canopy
hehe. that's the name of the game, with git. "and now i'll try..." 😆
pastel panther
@crimson ferry glad to help. The github documentation is really very good so give it a thorough read through. I'm pretty sure the key is having your git user.email set to one that is associated with your github account

@raven canopy "Any sufficiently advanced technology is indistinguishable from magic."

I really think there should be a git subcommand that deletes the repo and re-clones
raven canopy
haha. that would be handy. although, git reset --hard works pretty good for me. 😄
pastel panther
@exotic pumice just make an alias to do it for you
btw, no I did not test the trellis yet but I'm at a stopping point with my driver so I can give it a try now
exotic pumice
I've had instances where git reset --hard and git clean -f -d left me with differences, perhaps in a gitignored directory
raven canopy
ahh. good point. didn't think about ignore.

Or do you wanna join our gitter and talk to the other guys working on the libraries directly?
pastel panther

@meager fog back! Ya that code I pushed needs a bit of cleanup anyways, just wanted to share my progress. I'm interested to look at CMSIS structs but I don't know much about them.
Is there some reading material you can point me to?
meager fog
ok yeah
soooo
the thing is - with registers being objects, they take a lot more memory
i can squeeze em down a bit because i have some extra member variables but it definitely adds up
the way we did 'bits' before is with a struct
manic glacierBOT
meager fog
i gotta get a clang linter at some point, too many tab/spaces issues
but basically you end up splitting the register's uint8_t or whatnot, into a struct, instead of a definition of a register object for each bit
pastel panther
ah
meager fog
but i think for now lets stick to what we gots
pastel panther
okie dokes
meager fog
i think if you get to like 6-8 RWbits then we should look at maybe using cmsis
manic glacierBOT
meager fog
@pastel panther nice

@meager fog I'm gonna head out for a bit to enjoy the break in the rain but I should have something later tonight
crimson ferry
Got the git / ssh process working, one final (I hope) process question... I assume the best place for me to test my change is while I have my branch checked out, changes just made, git status = clean tree, probably after last anticipated commit before PR, but definitely before push back to my fork. Testing by copying changed file(s)/lib to my device(s). Or is there a better flow?
idle owl
@crimson ferry Testing anywhere along the way is good. I'm bad about iterating within my git directory and instead often do it on the board (Which can lead to losing code if something goes wrong). What you're suggesting above is an excellent workflow.
crimson ferry
Thanks, @idle owl. I was following your Guide but don't want to get too far without confirming it still works 😉

umbral dagger
@idle owl @crimson ferry I have a "deploy" alias defined that copies *.py in the current directory to my CIRCUITPY drive and does a sync (to make sure everything finished writing). I work in my working dir and deploy to test (the auto-reload causes a restart when I deploy).

i git clone directly in and then commit when its in a good spot - kinda funky tho 😄
exotic pumice
@pastel panther ok I will when I get home
exotic pumice
@pastel panther this one only uses 3 neopixels, I think we've identified the problem as a slow timer
oops wrong file
in other news, I got this lcd that is most definitely not an ili9341, and the code for the controller it actually has only works on avr arduinos it seems https://www.aliexpress.com/item/5pcs-lot-2-4-inch-TFT-touch-LCD-Screen-Module-For-Arduino-UNO-R3-Free-Shipping/1814766122.html?spm=a2g0s.12269583.0.0.6bacbebcdBJiVu
not sure what to do with it
main meteor
Looks like an HD44780 pinout to me.
Then again, the listing says a spfd5408 controller.
pastel panther
also says ili9341😜
main meteor
Yeah, title says one thing, description says another
Probably not too hard to fold SPFD5408 support into the adafruit_rgb_display library.
exotic pumice
@pastel panther https://twitter.com/bascule/status/1104600470725656577
pastel panther
yaaaay!
exotic pumice
yeah, this is using the assembly delay version, with link time optimization disabled, and compiler optimization set to "s"
it would be nice to get the timer version working too
because then people can run with whatever optimizations they please
we discovered our timers were only running around 500KHz
or actually, timers running at 1MHz, a toggle on two different ticks was 500KHz
I have no idea how that was working on Metro M4
must be some super tolerant neopixels

can you 'move' the repo?
you can move it to me ladyada
then ill move it to adafruit

hi, anyone know how many of the A1-A7 outputs on the CPE can do PWM output?
idle owl
@fierce girder CPX has PWM on the following pins: A1, A2, A3, A6, RX, LIGHT, A8, TEMPERATURE, A9, BUTTON_B, D5, SLIDE_SWITCH, D7, D13, REMOTEIN, IR_RX, REMOTEOUT, IR_TX, IR_PROXIMITY, MICROPHONE_CLOCK, MICROPHONE_DATA, ACCELEROMETER_INTERRUPT, ACCELEROMETER_SDA, ACCELEROMETER_SCL, SPEAKER_ENABLE.
There is NO PWM on: A0, SPEAKER, A4, SCL, A5, SDA, A7, TX, BUTTON_A, D4, NEOPIXEL, D8, SCK, MOSI, MISO, FLASH_CS.
fierce girder
thank you!
idle owl
You're welcome!
Obviously a lot of that isn't broken out, that's from a script that checks every possible pin that's available in dir(board). But it does tell you the A1-A7 answer.
fierce girder
@idle owl so for the gator clip friendly pads, that is A1, A2, A3, A6 ?
idle owl
Looks like it, yep!
fierce girder
great, thanks 😃
I had been looking in ./ports/atmel-samd/common-hal/pulseio/PWMOut.c and ./ports/atmel-samd/boards/circuitplayground_express/pins.c and was getting confused. I'll keep "dir(board)" in mind for next time.
idle owl
@fierce girder If you check out that guide page, it has a script at the end that tries to setup PWM on every pin, and tells you whether it was able to or not. That's how that list was generated.
fierce girder
ah@
stuck elbow
@fierce girder also note that some of the pins use the same timer, so it might be impossible to get pwm on all of them at once
fierce girder
stuck elbow
at least not with different frequencies
fierce girder
I see it now. I need better glasses 😃
idle owl
😄
fierce girder
@stuck elbow ah, good point. i had been hoping to use them as independent PWM outputs. I'll need to wire up LEDs and see if I can control independently
stuck elbow
you will get an error if you try to create pwm objects that conflict
fierce girder
ah. good to know

@errant grail might want to add a filter for the noise 😃
errant grail
Oh, if it was only noise. It's actually classical music...
Decided to rework the Range_Slicer library this past week to make it more universal rather than limiting to positive integers and only ordered inputs/outputs. Had to completely start over from scratch three times (or was it five times?) to approach the algorithm from different angles (thanks to my HS Physics teacher for the technique he taught me many years ago). Finally found the one I was looking for yesterday. It’s passing the tests!
Here’s an example of how Range_Slicer can quantize a relatively noisy potentiometer input signal (input: green trace, quantized output: blue trace). The Slicer class linearly processes any range of input values into a set of indexed output values.
Tasks this next week will be to complete the GitHub documentation, experiment with non-linear quantization and floor versus ceiling versus truncation methods. Will continue to develop the hardware prototype with the goal of sending the PCB and front panel design to the vendors by Friday. Planning to get deep into displayio for the relatively complex control panel display.
Also, today is the big day for the CircuitPython-lighted UFO film miniature’s 15 minutes of fame. Green-screen filming begins in an hour. Hope that the production team will let me post a few video clips for you to see.

Hi All,
I am trying to update a Feather M0 with rfm9x with the latest CP. The board shows up on my Windows PC, but only shows 48K available. When I double-press the reset button, it shows up as a serial port. Is there an existing guide to help me fix this?

@timber mango looks like you don't have the uf2 bootloader on it, try this: https://learn.adafruit.com/welcome-to-circuitpython/non-uf2-installation

if it's not an express board, then it's normal
it doesn't have the extra flash chip for the filesystem

I imagine it would be better to close the current PR, create a 5.x branch, and then push the change there. or, could just leave it on the dm-mixer branch where it actually lives currently, and re-PR from there when the time is right. /post-meeting-thoughts

@stuck elbow Sadly the motor controller set of required libraries are much larger than 48K. adafruit_register is big enough alone to fill most of the storage. It's OK, I can order the M0 express and a rfm9x wing.
It's the price of not doing more research before ordering, so it's on me 😃
idle owl
@timber mango It might be worth ordering the M4. If you can.
timber mango
M4 is out of stock sadly
idle owl
Ah
raven canopy
check digikey, etc?
timber mango
I will, I have a whole cart of stuff from Ada that I'll let sit for a week.
raven canopy
also OoS. 😦
stuck elbow
@timber mango those .mpy files are only 2kB each, and you don't need all of them
check if you have any hidden files in there that take up your space
timber mango
stuck elbow
@timber mango get the .mpy files from the release: https://github.com/adafruit/Adafruit_CircuitPython_Register/releases
and I think you only need the i2c_struct.mpy

Thank you @stuck elbow is there a way to go and find those for each library? I looked for Adafruit_motor but didn't find one, etc.
stuck elbow
click on "releases"
next to "commits"
or download the bundle, to get them all at once, and just pick the .mpy files from there
timber mango
I pulled down the bundle and that's where I got the larger file sets. I couldn't find the actual library links, but found this and it links to each of what I need. Thank you, and thanks for your patience! https://github.com/adafruit/Adafruit_CircuitPython_MotorKit

@timber mango definitely snag a M4 when they're back in stock. Having that board makes LoRa development a lot easier, espcially if you want to use lorawan

@raven canopy let's just sit on it until we branch 4.0.x
I don't care if we do 5.0 in a month with the mixer stuff
@tulip sleet https://github.com/adafruit/circuitpython/pull/1624
raven canopy
ok. so leave the PR open? i'll look through and see if i can help with anything on 4.x. i will at least push my currently-building work to dm-mixer.
raven canopy
i'll try. let me spin that up.
slender iron
otherwise we'll need a new pr

hmm. i get no refspec on git push upstream dm-mixer. should the refspec be like this: git push upstream :dm-mixer?
slender iron
what remote is upstream?
raven canopy
adafruit
slender iron
add dean's repo as a separate remote
raven canopy
he commited straight to adafruit, afaict

back into the foxhole
yeah...progit book tries to explain the refspec...oof. 😄
but that also makes sense. refspec = <source>:<destination>
note: if you see a upstream/dm-mixer branch...sorry. 🤣

@umbral dagger and @gilded cradle have done some animations on led matrices but I'm not sure about text
umbral dagger
@modest atlas samd21 is going to be limiting judging from my experiences with the dotstar featherwing and a Feather M0 Express.
You could look at the guide I did for that (over a year ago) for some ideas. I did text scrolling on the 6x12 dotstar matrix.

cool, got it
should I add the ina260 board somewhere or did you want to review it first?
orchid basinBOT
Add stable vs unstable coloring. Also add S3 and GitHub links for
leading edge builds and past releases respectively.
Lastly, import 3.1.2 as a one off stable release using a hacked up
script.
timber mango
thank you @stuck elbow for the tip on using the precompiled modules. I managed to get all my libraries loaded, along with a basic stepper test. 😃
3KB to spare after the test code, now I have an excuse for leaving out the comments
gilded cradle
@modest atlas, I did some animation for examples in the Adafruit_CircuitPython_FeatherWing library using some shifting functions I implemented. I didn't do text yet because I was going to look into using an existing library such as Adafruit_CircuitPython_Bitmap_Font, though I'm not sure if that would work or not.
tall granite
what feather[s] are good for wifi and/or BTLE and support CircuitPython?
tulip sleet
@solar whale on nRF52840, in order to fix a bug, I have stopped using the high-speed SPI peripheral (SPIM3). That leaves peripherals TWIM0/SPIM0, TWIM/SPIM1, and SPIM2. The 0 and 1 periphs are shared I2C/SPI, but due to interrupt-handler issues, we can't dynamically choose between the two. So there's the choice of providing one available I2C bus and two available SPI buses, or vice versa. We consulted and chose the former (more likely to need multiple SPI buses), but if you have other considerations, let us know). Your opinion is appreciated.
@tall granite nRF52840 feather does BLE. CircuitPython 3.x supports wifi on ESP8266, but we are dropping ESP8266 for 4.0 and providing wifi via an ESP32 co-processor now instead. The PyPortal is the first example of that (SAMD51 with on-board ESP32 co-processor modules). 4.0.0 is in beta now. BLE support is currently peripheral only, but central will be added in later 4.x versions.
tall granite
@tulip sleet awesome, thanks. Does that mean that the Feather HUZZAH32 will be supported in cp 4.0
or, not because it's the main processor, not co-
tulip sleet
No, because we'd have to do a complete port of CPy to that chip, which is a lot of work. It's much easier to use it only as a co-processor, for a number of reasons.
solar whale
@tulip sleet Does the access to the SPI flash use one of the SPI buses so in general one remains for other stuff or is the SPI flash handles separately.
tulip sleet
ESP32 has software and hw peculiarities, is not so well documented, etc. We'd rather be able to swap out the wifi co-processor if needed. We are using this library as glue between the main and co-processor: https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI
@solar whale there's a separate QSPI periph, so there's no conflict
tall granite
I wonder if there will be a feather in the future that uses esp32 as coproc and supports CP4.. looking at the huzzah32 there's not much room for another chip!
tulip sleet
@tall granite there's always new hw in the works, watch this channel for "LEEKS" and check out the "Top Secret" extracts from Ask an Enginner shows on youtube
solar whale
@tulip sleet OK -- The only time I think a second I2C bus is used is for some boards with - on board sensors - like CPX, Hallowing, Neotrellis -- Are there any plans for similar nrf52840 boards ?
tulip sleet
@solar whale, exactly, we'd flip the choice for CPX, etc. and have one private I2C, one avialable on board pins, and one SPI on board pins. I'll be adding some conditional compilation for that. And/or Nordic can fix their bugs
solar whale
AH - sounds good
tulip sleet
nordic forum indicates people are having other issues with SPIM3 32MHz SPI as well at higher speeds, so perhaps best to avoid it for now
solar whale
@tulip sleet I misspoke(typed) It looks like only the CPX uses an "interenal" I2C bus. The others (pyportal,hallowing ) have the sensors in the SDA/SCL pins that are exposed as well. So only CPX is "different" I guess that is due to the limited number of pins available on the CPX. Can't afford to dedicate 2 to SCL/SDA.
tulip sleet
that's helpful to know - one I2C bus is probably fine for most people
solar whale
neotrellis accel is on a separate I2C bus as well ...
main meteor
I saw a leek for a good-looking compact board using an ESP as a coprocessor. I expected it to be available before the more complex PyPortal, but that isn't how it happened.
stuck elbow
not all that gets leek-ed gets finished
main meteor
Also true. Back when I was using PIC chips, they announced an 18F010 which had a whole bunch of compute hardware in an 8-pin DIP. I still have the data sheet somewhere, but it was never made.
stuck elbow
and sometimes it does get released, but in the mean time the concept changes so much, that it is unrecognizable from the original leek
main meteor
I'm kind of hoping the little ESP coprocessor board shows up, as it seems useful in its own right, and wouldn't involve much hardware or software engineering effort/risk (basically just a smaller PyPortal without the screen and some other peripherals).
solar whale
Sounds like a particle argon withs an SPI interface to the ESP32
main meteor
However, I'm well aware AdaFruit has a lot of irons in the fire, nothing is standing still, and there are only so many hours in a day.
It could be that someone decided the Argon would fill that rôle and another part wasn't required.
Also, my use cases aren't everybody's: I'm intrigued by the power and solid environment of an M4 with the connectivity of an ESP, but without the size and expense of a PyPortal.
solar whale
Agreed -- That is why I like the Argon - nrf52840 has BLE and I can use the ESP32 with ESPATControl, but ESP32SPI is much better
crimson ferry
Yeah a breakout would be very cool, and agreed seems low-risk. Even a FeatherWing wouldn't need any new tech. I like my PyPortal and have some good uses for it, but I also have use for a small fleet of CP-WiFi devices that don't have TFT, to evolve my Arduino ESPs toward.
So far, just joining ItsyBitsy M4 and Feather M4 to Feather ESP32, but the latter especially is more expensive than necessary. At least both combos fit on a 1/2-size board with a little nudging in the x, y, and z axes 😉
main meteor
I am amazingly fond of the ItsyBitsy M4 Express.
manic glacierBOT
stuck elbow
I think it shouldn't be so hard to look at the schematic of pyportal and make an esp8266 or esp32 featherwing
I mean, since you take power from the board and don't need the usb connection, it's basically just the module and nothing else
crimson ferry
Having the USB makes esptool flashing really easy, but I'm guessing if three's an ESP32SPI breakout, it will be pre-flashed. Then the only issue is NINA fw updates. But yes, custom is always possible, e.g., https://github.com/maholli/SAM32
simple pulsar
I'm using 4.0.0-beta.3-4-g186e31591-dirty which is a minor variant of 4.0.0 beta 3 from @tulip sleet . I just noticed when it spat an exception from my near-perfect code down the serial line (via normal USB connection) that I didn't see the full output. When i hit return the rest appeared. Was that my imagination or is there a difference/ buffering bug in the output now for 4.0.0 betas?
This could be my imagination, I'll try and reproduce
I've reproduced it

@solar whale When you have time, could you review this PR (https://github.com/adafruit/Adafruit_CircuitPython_AdafruitIO/pull/17)? It uses the updated header encoding in ESP32SPI and drops the way the lib. manually encoded headers, so you'll need the latest ESP32SPI lib.
