tulip sleet
I could make it smaller, but we have 1MB flash.
slender iron
ya, not worried about that
tulip sleet
I was thinking of storing it as json to get going quickly: ineffeccient, but easy to parse
tulip sleet
hmm, now I'm confused about placement; let me look at this again
no, not really, there are some variable length things. Basically we need a dictionary, but the lookup could be inefficient
hmm, in the old case, the filesystem was just below the botloader, so why did I think it wasn't??
slender iron
fatfs is: ```
hex(0xad000 + 0x40000)
'0xed000'
the microcontroller.nvm region was carved out of something, I have to go look (See, this is why I changed all this, it was really confusing)
slender iron
ya, totally
the new code is much better
we should add an assert to verify the location of the filesystem
or not
it'd be good to have a test somehow
tulip sleet
good idea, and same in atmel; I can verify it's a certain fixed location for SAMD21 and SAMD51. I can do that at build time
do you want to check at run-time? build is probably good enough
could be #error or #warning
slender iron
ya, build is fine
tulip sleet
ok, I'll push another commit to the PR after figuring this out and putting in a check. I still don't know why the current internal filesystems on the nrf are so broken. But they seem to work with a debug build, so could it be the nrf flash write alignment bug, or maybe it's timing?? have to debug this
I'll pull in jepler's latest PR and check again
slender iron
lets not wait for a fix for this pr
tulip sleet
no, no, not worth it, just trying to understand.
slender iron
๐
tulip sleet
@slender iron ok, fyi, nrf microcontroller.nvm was trimmed off the top of the internal filesystem. It was always 4K. The internal filesystem allocation was always present even if it was not used (because we have so much flash). We always used nrf52840_1M_256k.ld, which defined the FLASH_FATS as 100kB, starting at 0x019000. And so the internal filesystem was really 96kB, which is ... not that big
ok, it's worse
slender iron
we could change it for nrf. its only atmel internal fs I'm worried about
tulip sleet
FLASH_FATFS (r) : ORIGIN = 0x000E7000, LENGTH = 0x019000 /* File system 100 KiB */
>> 0x000E7000 + 0x019000
1048576
>>> hex(0x000E7000 + 0x019000)
'0x100000'
>>>
i.e. the filesystem overlapped with the bootloader, and the nvm is at the top of flash, also where the bootloader config is, which is also wrong
slender iron
fuuuuun
tulip sleet
!!
slender iron
that may explain the issues
tulip sleet
ugh, ok, I'll rationalize this
slender iron
thanks!
tulip sleet
it doesn't explain why it's breaking in the new builds based on my PR, but I think it's breaking differently
slender iron
its ok to break nrf internal fses
slender iron
ya, and they currently don't work well
tulip sleet
yes, I would rather not preserve a damaged filesystem
tulip sleet
@slender iron I was looking at the wrong .ld file, nrf flash layout is @slender iron not so bad, 256kB at a fixed location, but the microcontroller.nvm region is still 4kB carved out of the top of that. So I'll move the filesystem to just under the bootloader and we can grow BLE and nvm down from there.
and we will have more space available on Express boards anyway

I don't know what to expect, but a 350mA battery is enough to play back the whole "science is real" mp3 format album (40 minutes, give or take). One song was truncated, I need to verify whether the problem is in the original or a playback glitch.

@uncut mural You'll need to load some libraries on your board, but here is an example using the Circuit Playground library. ```python
from adafruit_circuitplayground.bluefruit import cpb
while True:
x, y, z = cpb.acceleration
print(x, y, z)```
onyx hinge
yay after a night to sleep on it, I found the mp3 stereo problem on samd pretty quickly.
pointers r hard
And the truncated track plays the same in vlc
tulip sleet
@solar whale here's another one, with the volatile fix combined with PR #2371, which reorganizes the storage layout. CIRCUITPY will be at a different place in flash, so it will get re-created, so save its contents first if you need it. Than you for testing!

Ok - but I think that caused hard reset on nrf dongle. Will retest when I get back home.

@ionic elk I'd just cd lib/tinyusb; git checkout master;git pull (maybe that's obvious). Then I need to do some kind of smoke test on each platform.
tulip sleet
yah
just some kind of smoke test - do you get CIRCUITPY and can you talk to the REPL?
ionic elk
Hmm it's probably past due for me to pick one of each up, I've just got atmel rn
Should I just post a PR and request assistance testing for now?

good idea, but don't let that hold you back on updating; others can check
tulip sleet
frankly, I just got a spresense too, and haven't had time to load anything on it
ionic elk
are there any restrictions on what feathers work with circuitpython?
there's quite a lot of them it seems like, do they all work or just a few?
tulip sleet
pick an express. But I would say pick up Metro M0 and M4, as they have the SWD connectors.
ionic elk
I don't see the Bluefruit LE on the boards list for example
tulip sleet
And Feather nRF52840 because it has or you can add SWD connector
ionic elk
Looks like we're out of stock on the express feathers
tulip sleet
metro is better for dev
also can get acrylic baseplate and a half-size breadboard
if you want to jumper things to it
ionic elk
I'll probably just use it mostly for smoke tests, to be fair
tulip sleet
blefruit LE is nrf52832; old; no CPy
ionic elk
glad I asked. Looks like adafruit doesn't stock nrf metros. Where do you get them?
tulip sleet
we don't have them yet (I have a proto ๐ )
get Metro M0 and M4; Feather nRF528480

I'm not sure there's anything in the ada store that's actually circuitpython enabled other than the particles right now, from what I can see!

manic glacierBOT
onyx hinge
metro m4 express and nrf52840 feathers are my go-tos. both ship with SWD connectors.
but yeah stock is tricky and holidays make it harder
@quasi pulsar as a beginner, you should pick a board that already works with circuitpython. When you do that, your steps are short: First, install the uf2 bootloader if necessary. second, install circuitpython as a uf2 image. To adapt a new board, you'll need more in-depth knowledge
later if you want to go back to arduino, it's also easy to do that. Typically you just click the reset button twice and then "upload" your sketch. It'll erase circuitpython in the process.
you can ask more in #help-with-circuitpython

It actually really ticks me off that you can't prohibit deleting files during a merge with git. Is it really so crazy that you'd want to split up work with a new branch? https://stackoverflow.com/questions/1407638/git-merge-removing-files-i-want-to-keep
slender iron
@shell falcon @indigo wedge has it going but hasn't released the code yet. We do have TinyUSB support for it now
indigo wedge
the whole mimxrt10xx family is quite similar, i have CPY working on both 1011 and 1062, i'm actually working on the code right now ๐
indigo wedge
currently working on the uf2 port for it, i now have separate bootloader and "app" memory space and the bootloader verifies the app before jumping to it, i can reboot to the bootloader from CPY with on_next_boot, working on double reset to reboot into bootloader, on the uf2 side i can readout the whole flash with current.uf, now just need to implement uf2 -> flash which shouldn't be that bad, i already use the external flash as shared XIP and storage
indigo wedge
the uf2 port i made is actually based on tinyusb with minimal changes which i think is quite promising cause it means in the future we could move all the uf2 ports to tinyusb
slender iron
I was thinking it'd be cool to have split uf2s, one for circuitpython and one for the default fs
@indigo wedge yes! I've wanted to have that
indigo wedge
cause for example tinyusb already supports stm32 so if we have a uf2 port for tinyusb then we get a lot for free, "just" need to implement flash read/write and few hw details

"MP3 V0"?
I found that it DID work with most of the lame-encoded VBR files but there could sure be exceptions still

my usual parsing tool on linux thinks it looks very much like the other file: bartlebeats - Frequency - 01 Idea3.mp3: Audio file with ID3 version 2.3.0, contains:MPEG ADTS, layer III, v1, 128 kbps, 44.1 kHz, JntStereo
@meager fog how inconvenient a gear switch would it be to try that file against the arduino version?
(I never actually did anything with the arduino version besides make sure it still seemed to build)
on both "MP3 V0" and "MP3 320" format downloads I get the same "parse" error ๐ฆ ๐ฆ
argh why do my mp3s work but these don't
@meager fog I removed the id3 tags with commandline program "id3v2 -D *.mp3" on Linux and now it plays for me

Ballpark, how fast should I expect to be able to download data over an airlift with circuitpython? is it in the realm of possibility to, say, do a pyportal podcast player that streams mp3s ? The first random podcast I looked at is 160kbit/s = 20kB/s which doesn't feel like a lot..
I wonder how many other missing pieces there are to parse rss feeds and so forth
crimson ferry
RSS processing would be really cool
I've never tested Airlift bandwidth, but have the truncated response body issues been resolved?
A comment https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/issues/9#issuecomment-477935099 in one of the ESP32SPI issues indicates bandwidth ~160KB/s (default ESP32SPI SPI baudrate=8000000)

not sure i ever went through a pypi setup all the way before. so not sure everything needed to be checked.
want me to just merge and release?

Yes please. And then check Travis to verify it deploys.

Adafruit_CircuitPython_RGB_Display is what I checked.
Want me to edit the file?
tidal kiln
yah. just make that edit and see what happen
i can't remember where i got that syntax from, but i do remember going "really? that seems odd, why not just a dash?"
idle owl
The fun of troubleshooting deployment issues.

@tidal kiln ready to merge
Now for another release...
@tidal kiln do you want me to do the release or are you
idle owl
sigh.
Is it failing because the example file is empty? I feel like that's not it because we've had plenty that have been empty... but maybe it is?
It's failing to create the assets it seems like.
There aren't any assets on the lib releases either.
That's what's failing.
I'm not sure how to fix it.
The format of that line matches NeoPixel.
Except for the . being on a different line, but that shouldn't matter.
lone sandalBOT
tidal kiln
how are the release assets created?
idle owl
circuitpython-built-bundles I thought.
idle owl
Perhaps.
tidal kiln
even though it looks likes it:
https://travis-ci.com/adafruit/Adafruit_CircuitPython_NeoPixel_SPI/builds/141001875#L332
idle owl
Adding a docstring.
tidal kiln
to the example?
tidal kiln
it's building some of the assets
idle owl
The source code always attaches. It's not adding the bundled assets to the release.
idle owl
wait, now it's failing on a different asset
now it's failing on the .py bundle.
I'm grasping here.
idle owl
Thing is The command "circuitpython-build-bundles --filename_prefix adafruit-circuitpython-neopixel-spi --library_location ." exited with 0. it succeeds.
tidal kiln
right, but why aren't they on the release page?
idle owl
I don't know.
tidal kiln
trying to figure out how that part works...
ruby atlas
Does Adabot have permission to upload release assets to https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel_SPI/
It's possible the 404 is because it doesn't have permission.
```/home/travis/.rvm/gems/ruby-2.4.5/gems/octokit-4.6.2/lib/octokit/response/raise_error.rb:16:in `on_complete': POST https://uploads.github.com/repos/adafruit/Adafruit_CircuitPython_NeoPixel_SPI/releases/22219495/assets?name=adafruit-circuitpython-neopixel-spi-examples-0.2.2.zip: 404 - Not Found // See: https://developer.github.com/v3 (Octokit::NotFound)
hmmm. not sure. maybe not. if that's something that needs to be explicitly done after creating the repo.
ruby atlas
I imagine it would be. possibly as a collaborator or via secrets and deploy keys?
ruby atlas
api_key: "$GITHUB_TOKEN"
file_glob: true
file: "$TRAVIS_BUILD_DIR/bundles/*"
skip_cleanup: true
overwrite: true
on:
tags: true
``` looks to be the relevant magicso the account to which the token belongs needs to be able to write write to the releases.
idle owl
@tidal kiln CircuitPython Librarians needs to be write.
tidal kiln
yep. changed and trying again.
tidal kiln
@ruby atlas awesome. thanks. looks like that was it.
ruby atlas
you're welcome
tidal kiln
@ruby atlas i was getting a bit lost looking through the script, since it looks like that step happens via something that's boiler plate on travis side? so it's entirely setup via those lines in the travis.yml file?
ruby atlas
correct. the key was in the error message, not the traceback. It told us it was a failed POST to github release files.
tidal kiln
yep. i was just lost trying to figure out what was even doing that post.
tulip sleet
@idle owl I am back
idle owl
@tulip sleet Perfect timing, just finished with something else.
ruby atlas
anyhow, back to being invisible.
tulip sleet
so we want to be able to do from adafruit_circuitplayground import cp and have it do cpb or cpx as appropriate?
tidal kiln
@ruby atlas thanks again!
idle owl
@tulip sleet yes. and have the from adafruit_circuitplayground.bluefruit import cpb and .express import cpx still work as well separately.
tulip sleet
and both of those work fine now, right?
idle owl
yes.
tulip sleet
ok, hold on a bit and I'll try some things

Fix temperature example filenames```hmm, I didn't pull yet, rebuilding...
ok ,now I get the error, so it appears the stack is not quite deep enough for the restructured library
tulip sleet
increasing the stack size a bit and rebuilding to verify...
idle owl
ok
tulip sleet
stack size was 4096; increased to 4500 and it works :/
idle owl
I wish it had been that my build was broken.
tulip sleet
I'll look to see if there's anything that can be done to reduce the call nesting on import.
idle owl
ok
onyx hinge
It could be compiler differences, gcc9 behaving differently again?
tulip sleet
we are doing a little more nested calling on import. I think it's just that the 4096 stack size on SAMD21 is not adequate
onyx hinge
ah
tulip sleet
it works with the old library; this library does more work on import
idle owl
why because of the separate base class?
tulip sleet
that and the code in __init__.py`
idle owl
oh.
i mean there were no functional changes to the lib for express... i guess i thought it would behave the same.
but it makes sense.
tulip sleet
i'm trying different stack sizes...
4500 works, 4400 doesn't. I lucked out trying 4500 the first time.
there's nothing wrong structuring the cp library the way you did, with a subclass. this boils down to the tight space in the SAMD21's. Increasing stack size to about 4500 bytes from 4096 is only 10%, maybe we just need to do it. Have you encountered "max recursion depth" errors on cpx code in the past?
the lis3dh initialization could be deferred until .accelerometer is called the first time, that would save stack space.
idle owl
@tulip sleet I've not run into this before that I remember, but who knows.
I might not remember
wouldn't it end up initing it every time it's called in the loop though? or how would that work?
tulip sleet
no, we'd just check for something null. I'm going to try a little reordering of some code

I just noticed that I can't open many of the recent schematic files in Eagle on my Mac -- I tried PyPortal and PyPadge and CPB. It is the .sch files that fail -- can others open these? for example https://github.com/adafruit/Adafruit-Circuit-Playground-Bluefruit-PCB
gilded cradle
Ok, thanks @raven canopy
idle owl
@solar whale what version of Eagle are you using?
solar whale
7.7.0
idle owl
I'm running 9.4.1 and I'm not entirely up to date.
I can open the files. Maybe they've stopped working with that version?
solar whale
hmm -- ok -- i'll see if I can update -- using the "free version"
idle owl
Right. Yeah see if there's an update to it that still lets you use it etc.
solar whale
if not, it was fun while it lasted ๐
tulip sleet
free version is still available for 9.x
solar whale
yup -- just found it -- I thought I updated it recently...
ah --- I have multiple version installed....cleaning up
tulip sleet
@idle owl this has stack size 4504 (divisible by 8, which is slightly a good idea for us). It works for me now. I'd like to talk to Scott about it a bit. I think increasing the stack size is OK for 5.0.0, we only lose 500 bytes of heap. For 4.1.0 it's not an issue becaue we wouldn't update the frozen libs for 4.x. We could do some contortionist stuff in the CP library to avoid this, but I'd rather not.
i have to start cooking mac and cheese and will be going out for a while around 6pm

@solar whale excellent

raven canopy
redis error resolved. only introduced one new error in the process... PR imminent.
tulip sleet
@slender iron if you look above, you'll see that the CP library with a base class now overflows the CPX 4kB stack when we add an __init__.py, due to a rather deep stack on initialization. Increasing the stack by 10% fixes the problem. Do you think it's fine to do this for CPX? We could do it just for CPX or all SAMD21 boards.
slender iron
I think its ok to increase the default stack size. it can be changed through supervisor if needed
tulip sleet
this is due to implmenting from adafruit_circuitplayground import cp
ok, sounds ok, and easiest to do for all boards. 400 bytes less of heap is not terrible.
tidal kiln
what's the difference in these two travis jobs?
raven canopy
i'd say nothing. i think its showing up like that due to the UI changes related to GitHub Actions/Checks. the bottom one is a direct link to travis, whereas the top one goes to the Checks page.
tidal kiln
thanks. thought it might be related to that. seems to have shown up about same time.
raven canopy
@tidal kiln oh wait! one is on .com and the other is on .org.
so that repo is enabled on both sides...
noticed it after trying to match the job numbers.
tidal kiln
so..two jobs running?
raven canopy
yeah. just need someone with the credentials to goto travis-ci.org, and turn that one off.
and possibly remove the webhook in the repo settings.
or...just wait until dylan gets it migrated to Actions (and deletes the .travis.yml). ๐
reminds me...we need to update cookiecutter with the new actions stuff.

We just covered the Xmas tree in neopixels. I'll have to get a video if possible. We added more to the Animation library since with the goal of the tree bring epic. :)
solar whale
the sparkle animation is great if you shake the remote!
these CPB's are really nice -- it's so great to see all the work on BLE coming into play.
solar whale
@idle owl just a heads up -- I tried using my CPB + Gizmo as the Animator -- just had it handy -- it works fine as long as program is code.py or really as long as nothing that has the REPL display being sent to the TFT. If the REPL is on the TFT, then there is a lot of delay. It still works, but it is very sluggish. I just wanted to let you know in case it comes up. Lots of folks have the CPB+Gizmo now. It only makes sense to run it as code.py but just in case someone stumbles into this ....
sorry -- it was as the Neopixel Animator that I ran into the sluggish behavior -- probably either way since it is continuously writing to the console and that is much slower to the TFT.
It is really nice to just plug a JST 3pin Neopixel string into the Gizmo

Hi, I'm trying to get one of these OLEDs https://www.amazon.com/MakerFocus-Display-SSD1306-3-3V-5V-Arduino/dp/B079BN2J8V/ref=pd_sbs_263_t_0/146-7505350-8634301?_encoding=UTF8&pd_rd_i=B079BN2J8V&pd_rd_r=5317892a-2880-4dfc-8f0f-7ab17c57edc0&pd_rd_w=mADHh&pd_rd_wg=F9fQr&pf_rd_p=5cfcfe89-300f-47d2-b1ad-a4e27203a02a&pf_rd_r=Z0Q6WBNXWQGHGF6TTR30&psc=1&refRID=Z0Q6WBNXWQGHGF6TTR30 working wtih the feather M0 express running circuit python 5.0 Beta.
I thought the instructions from here https://learn.adafruit.com/monochrome-oled-breakouts/circuitpython-usage would have worked, but there is a RESET pin that's defined (reset=board.D9). This pin isn't available on the OLED I got. Any pointers on how to eliminate the need for the reset in code? Not sure if that's possible with the SSD1306 or displayio library.
The display works because I was able to verify it with an Arduino UNO and the u8glib library. I also have 4.7k ohm pull-ups connected on the M0 express SCL. SDA. Thanks.
quasi fjord
the reset pin is optional, you can just skip it
barren peak
display_bus = displayio.I2CDisplay(i2c, device_address=0x3c, reset=None)
is that ok?
I thought I saw that as an option digging into the code.
I tried without as well, but no luck. The i2c address is 0x3c which is the default in the example, so should be ok there.
quasi fjord
I don't think you want to use I2CDisplay directly, you probably want to use the SSD1306 library: https://github.com/adafruit/Adafruit_CircuitPython_DisplayIO_SSD1306
barren peak
@quasi fjord thanks for the replies. No luck with https://github.com/adafruit/Adafruit_CircuitPython_DisplayIO_SSD1306/blob/master/examples/displayio_ssd1306_featherwing.py I dropped this example into Mu, but nothing on the screen. Definitely have 3.3V going to the oled.
timber mango
Is it physically connected to anything right now? It's probably an active low pin, so tie it to 3.3 V.
barren peak
@timber mango not following. Tie the D9 reset pin to 3.3v?
timber mango
Probably, yeah. I don't know anything about this board but often reset pins need to be held high to not reset. (Although on the other hand, floating should normally not be a problem...)
raven canopy
the schematic on the amazon page shows that reset is held high. at least, i think its showing that. ๐
barren peak
no luck. I think there's something fundamental in the SSD1306 library preventing it from working.
timber mango
@raven canopy ah ok, thanks for looking it up. So i guess it has an internal pull-up, that's what i meant: not "floating" but not connected (which then isn't a problem because of the pull-up). @barren peak Alas! Good luck tinkering ๐
onyx hinge
Trinket m0 inside

@timber mango @raven canopy I was able to fix the issues with the display not working. I did not have the adafruit_display_text library installed. https://learn.adafruit.com/adafruit-oled-featherwing/python-usage featherwing.py worked as-is with the OLED I referenced earlier. Thanks for chiming in to try and help earlier.

@solar whale Thanks for the comments on my project! ๐ Given that there are a lot of display Gizmos out there, it might be worth making the prints optional. Good to know though, in case anyone reports that behavior.
solar whale
@idle owl You are most welcome!
idle owl
@onyx hinge You alive?
onyx hinge
@idle owl good morning, what's up?
idle owl
There's an audio thing I either don't understand or is broken.
onyx hinge
OK, I'd be happy to try and help!
idle owl
This example - line 37, loop=True does nothing. The sample doesn't loop. Which I guess makes sense to me because it shouldn't keep looping, there's no loop in the code. However, add it to a while loop, and it repeats whether or not loop=False or True, so... what am I missing here, or is loop in this case totally pointless? https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/master/Introducing_CircuitPlaygroundExpress/CircuitPlaygroundExpress_AudioSine.py
A user filed an issue for it, and I'm finding the same results they are. loop appears to do nothing.
onyx hinge
okay, that sounds fishy. There is a bug about how "loop" works with RawSample on nRF, right now it always acts as if loop=True was passed.
What loop=True means is, roughly, "whenever the sound finishes playing, call play() with it again"
onyx hinge
but you would still have to have a while something: sleep loop in Python to keep your program from ending
idle owl
That's what I thought
onyx hinge
if you reach the end of your whole program, circuitpython stops the sounds and waits for reboot. I would have guessed that was the same on samd an nrf
idle owl
but at that point, if loop is False, it would keep going right?
idle owl
Hmm
onyx hinge
so your user is telling you that this does NOT play the audio for 1s then stop? audio.play(sine_wave_sample, loop=True) # Keep playing the sample over and over time.sleep(1) # until... audio.stop() # We tell the board to stop
if so that's a different bug than I thought it was
idle owl
wait... yes. it does. They are expecting it to continue looping forever because of the comment.
onyx hinge
#2078 says that even if you omitted loop=True you would get the same result
idle owl
But if loop=False, it does the same thing.
onyx hinge
or yeah put loop=False. False is the default.
the user is right to see that something is hinky with loop=
but eventually there will be a bugfix for loop=False and if they didn't put loop=True then they'd just get a short burst of sound and then silence for .98 seconds
idle owl
hmm
onyx hinge
this is probably not very helpful for you to resolve the reported issue ๐
onyx hinge
what if the comment said ```# Keep playing the sample continuously
until...
we tell the board to stop
though .. over and over and continuously are the same
the problem is the dual meaning of "loop" but you can't fix that since it's in the code, not the comment
idle owl
yeah
onyx hinge
I am putting myself in the user's mind and see why you would say "wait, what happens if loop=False" and you see no difference and it is confusing as heck
so I totally agree with where they're coming from, but .. it's just a known bug in the code I wrote that I haven't been back around to fix
idle owl
Ok
onyx hinge
(actually I tried to fix it for about 2 hours once and couldn't figure it out. ๐ฆ ๐ฆ )
idle owl
@onyx hinge This plays for 1 second. python audio.play(sine_wave_sample, loop=False) # Keep playing the sample over and over time.sleep(1) # until... audio.stop() # We tell the board to stop
on CPB
onyx hinge
right, on nRF it does, because of that issue #2078. on samd, it would give a very short chirp and stop, and that's what it should do on nRF except .. bugs
onyx hinge
of course
if it's troubling users, I should potentially make it higher priority to look at it again.
since you're lucky if 1 of 10 people speak up
idle owl
I'll see what Limor says. She assigned the issue to me, and I'll reply to it. And find out what she wants done.
I'll link that issue.
onyx hinge
OK, just so I know if the importance of that bug should be escalated
idle owl
Yep. I'll let you know
idle owl

I just lost my serial connection with a Cntrl-D at REPL on a CPB running 5.0.0-beta.1 - has anyone else seen that happen?

why is there an october function in circuitpython, but not a december function?
onyx hinge
hmph, my working theory was that display update was what was making me crash during mp3 playback, but I just gone one and I thought display was not being updated in my current WIP version
Is this typical of how fast an image (bmp) should load from SD? The file itself off just 48kb.. it takes seconds and seconds!
my display group is a large text with this image under it
tulip sleet
That is too slow. Try an older version of CPy to see how it works. Is this a .bmp?
onyx hinge
yes, it's a bmp file
I think I should probably also try it without the text there
it is weird that it is filling from right to left, isn't a bmp organized from top to bottom or bottom to top, typically?
idle owl
@onyx hinge https://github.com/adafruit/Adafruit_Learning_System_Guides/pull/971 Good?
onyx hinge
@idle owl I think the explanation can't hurt, but users will remain puzzled until I fix my bug
idle owl
Right, I'm not including the bug in the comment.
I included a reference to it in the issue
onyx hinge
and I don't think you should put a comment about the bug, that is not typical of how guides are .. right?
onyx hinge
It should be fixable, I just haven't found the right mind to be in to fix it
idle owl
Right, that's my point
onyx hinge
BMP 125x128 125x128+0+0 8-bit sRGB 48266B 0.000u 0:00.000

tulip sleet
try it with the simple slideshow demo: https://learn.adafruit.com/creating-slideshows-in-circuitpython/load-the-software
onyx hinge
I tried with this code: https://learn.adafruit.com/circuitpython-display-support-using-displayio/display-a-bitmap
it looks like they both use a TileGrid
4.0.0 Beta 2 replaces Sprite with TileGrid so use either.
self._sprite_class = getattr(displayio, "Sprite", displayio.TileGrid)
i'm trying it on a pyportal, but have to reload some stuff
onyx hinge
using the files from display-a-bitmap and my code based on display-a-bitmap it's just as slow
tulip sleet
i'll be back in a few mins after testing
tulip sleet
yes, it is fine on the pyportal
onyx hinge
If I transpose the image it's fast..ish
My hypothesis is, it's drawing in an order that is good for the display but is really bad for reading from SD
tulip sleet
if you read from CIRCUITPY instead of the SD card, how is it?
i see the same thing as you with other bitmaps on the PyGamer
scott idly said the other day how slow OnDiskBitmap was
tulip sleet
time to file an issue ๐
onyx hinge
will do
onyx hinge
OK that's what I know.
I wonder what to do for workaround. copy each bmp to internal flash?
.. as I use it

@solar whale Do you think it's worth updating my code to comment out the print statements and make them optional so it's faster with a Gizmo?
I can leave the single event prints in there (i.e. when the switch is changed, etc), but comment out the color stream.
solar whale
@idle owl I have nat tried that yet, have you? just want to make sure that is all it would take -- if so, I think it might good. I'll try it now
idle owl
With it being BLE, people aren't that likely to be connected to the REPL anyway. It's meant to be wireless.
@solar whale That would be great if you could test it
solar whale
ok -- will take few minutes
idle owl

belated hug report to @tulip sleet for reading all the micropython issues
slender iron
@pastel panther the box storage is similar to the storage boxes. just for a lot of them
wow, that doesn't make that much sense
pastel panther
lol
slender iron
I think the individual boxes are much pricier than the 12x12 box of them
pastel panther
ya, I prefer the modular approach because I can size it to my needs and organize them to my whim with things of different sizes
like my jellybean box is about the size of a paperback

@ionic elk, I thought it would be fun to get CP running on the NumWorks calculator , which uses an STM32.
ionic elk
I saw that! That'd be lots of fun
stuck elbow
@errant grail I have a huge bag of SD card boxes, they stack very well
gilded cradle
The earlier version uses an STM32F4 and the second uses an STM32F7
ionic elk
Ah gotcha I was about to ask
errant grail
@stuck elbow oh, excellent idea.
ionic elk
I saw the second one I think and kinda wrote it off
pastel panther
lol jeplayer
gilded cradle
The one I got from Adafruit was the earlier version.
stuck elbow
@errant grail just get ones without any guides inside
gilded cradle
If you need the schematic, I have it for the first one.
ionic elk
So I'll check it out. Does it have good options for reprogramming? That's the issue I've kind of had with the Meowbit

gilded cradle
@ionic elk, you could solder a 10-pin header on the area that says Cortex Debug.
ionic elk
@gilded cradle unfortunately mine doesn't have that (1.2.1)
pastel panther
@onyx hinge is that going to be a split or just printing in two pieces? Are you making it for an existing pcb or making a custom one?
gilded cradle
Ok, gotcha. I didn't realize you had one already.
onyx hinge
@pastel panther It's in two parts for printing, it's a regular (non-split) keyboard. Wiring is all point-to-point, like https://www.thingiverse.com/make:728072
(that's my make of someone else's design, now I'm making my own design ๐ )

is battery life enough to make having bluetooth worth it?

for this one at least I only need a few hours of runtime because I can plug it into one of the many micro-usbs on my desk between uses. I'll have to re-consider things for the full size version
