@tulip sleet i don't see any changes to that section in the commit history. 🤷

#

well, changes to the double quotes...

gilded cradle
#

There are no CPX assets at all even under releases

#

Just the ones with Crickit

tulip sleet
#

yeah, working on uploading those; one of the travis subjobs failed (it was supposed to send a PR to circuitpython-org). Downloading them from S3 and will add to the assets on github

gilded cradle
#

Ok. It doesn't seem that the link itself is broken, just that the file isn't there.

raven canopy
tulip sleet
#

ok, missing assets added. tnx @raven canopy, I'll look - I haven't been in the loop on circuitpython.org

raven canopy
#

yeah, i understand that its still a WIP. takes time to get these things working right, only to change them again. #ProgrammersDelight

#

want me to put up an issue?

tulip sleet
#

no, I think I'll just submit a PR; I think you're right about the template code being wrong

#

that was a good spot; lines 38 and 67 should be the same, hunh?

raven canopy
#

yeah, i think that looks right.

tulip sleet
#

says something about the sloppiness of the template language that it silently converted a single value into a list

raven canopy
#

hehe. jinja isn't perfect... i mean, its python underneath, but it has to handle loops on its own so they can get a little funky.

#

Good day,
I'm about to send a pull request (my 1st) on Adafruit_CircuitPython_INA219 but I have added some imports :
from adafruit_register.i2c_struct import ROUnaryStruct, UnaryStruct from adafruit_register.i2c_bits import ROBits, RWBits from adafruit_register.i2c_bit import ROBit
Apart from the code, is there any other files I should udpate ? requirements.txt ?
Thanks

pastel panther
#

@lofty nova you're register-ifying INA219? Neat! I think that's it but let me double check

#

setup.py will likely need it as well

lofty nova
#

Hi @pastel panther , exactly. I sent a PR yesterday for a little fix but ladyada suggested to take the opportunity to move to register

pastel panther
#

ya, saw that. I'll be happy to review when you get the PR in

lofty nova
#

Do you suggest I send the PR as-is ? Or should I update requirements.txt and setup.py before ?
Not sure how to do this? Is that in the guide ?

pastel panther
#

Are you working on a fork?

lofty nova
pastel panther
#

Perfect. Ya, I believe the guide should cover this but I would push the changes to your fork and test before the PR. It's not a big deal since the PR will update with any changes to make but you'll have to wait for travis every time you push so you might as well get the changes in before the PR

lofty nova
#

So is it just about adding 'adafruit-circuitpython-register' in both files ?

pastel panther
#

ya, I think that should do it

#

if not, no worries, we'll fix it

lofty nova
#

Ok I'll do this and send the PR. I don't have the full build environment so can't check this. May be there a guide on building I haven't read ?

pastel panther
#

fair warning there is a good chance you'll have some pylint errors when travis runs. It's a right of passage 😃

#

There are instructions on the CP INA219 repo on building the docs which you might try. Other than that the main thing is pylint which my IDE automagically does for me (VS Code)

#

I'm not sure if the guides cover pylint but I'll check

#

I didn't see anything so go ahead and PR when you're ready and we'll deal with anything that comes up

lofty nova
#

Done. Crossing fingers. I will read the build procedure and install what is missing.
I'm using Visual Studio 2017 on Windows 7.
Many thanks

pastel panther
#

@lofty nova Sorry if my response was confusing; you shouldn't need a build system for library work

lofty nova
#

Might be overkill for such a small lib but that's still something interresting to learn for may be a future work 😉

pastel panther
#

you only need to setup for CP builds if you want to do custom builds of CP or help with core work

#

I don't know what you would setup for libs since they're python unless you wanted to replicate what travis does

#

have fun either way and let us know if you have any other questions. I'll keep an eye out for the PR

lofty nova
#

Apparently pylint failed on the sample codes because of bad space

pastel panther
#

That and unused imports

lofty nova
#

Yes but I don't understand the unused imports

#

They are not in the test code, but in the lib code and I use them

manic glacierBOT
lofty nova
#

Or is that because I from adafruit_ina219 import * ?

pastel panther
#

Ya, I think so

lofty nova
#

I'm more concerned by the names. I don't understand as I see the same naming in examples of other libs.

pastel panther
#

I think you can just from adafruit_ina219 import ADCResolution, BusVoltageRange, INA219

#

What names?

lofty nova
#

Oh, I got many naming errors on my pylint but not in travis. Good.

#

Should I remove the PR to send a new one ?

pastel panther
#

No, just fix on your fork and re-push

#

It'll update with your changes

#

If you're getting different pylint errors locally than travis gives, you might want to make sure you're running it locally with the .pylintrc from the repo

lofty nova
#

I was using the .pylintrc but I just noticed that the pylint on the samples is adding --disable=missing-docstring,invalid-name

#

all ok now.

gilded cradle
#

Good job @lofty nova. Pylinting definitely gets easier. I usually run it locally on my computer to weed out the easy ones before pushing to Travis.

lofty nova
#

Thanks @gilded cradle . I do now but I didn't notice that there were additional args for the examples.

gilded cradle
#

Yeah, it's about practice. I remember being just as frustrated on my first PR.

Anyone else seeing this You are running in safe mode which means something unanticipated happened. Looks like our core CircuitPython code crashed hard. Whoops! Please file an issue at https://github.com/adafruit/circuitpython/issues with the contents of your CIRCUITPY drive and this message: Crash into the HardFault_Handler. with the 2019-03-15 build of 4.0.0-beta.4?

Having trouble getting the board to show up in windows when I double-click the rest. Any Ideas?

#

I get the right audio from windows to indicate attachment

#

Got all green neopixels on the CPX

meager fog
#

iray, windows sometimes gets super confused - but if you double click and get green LEDs the CPX is in bootloader mode. you could try another computer or USB port - are you on win7

#

win7 is egregious

obsidian dome
#

Win10

#

I can grab my mac and try that.

tulip sleet
#

@obsidian dome did it have circuitpython on it? Did the CIRCUITPY drive show up?

obsidian dome
#

@tulip sleet It had the Beta-4 on it

tulip sleet
#

so you double-clicked, but CPLAYBOOT did not show up, right?

#

did it show up previously?

obsidian dome
#

Got it recognized on the Mac and it rebooted.

#

Still crashing hard

tulip sleet
#

did you update to beta.5 yet?

obsidian dome
#

I did the Beta5 update

solar whale
#

FWIW -- on one occasion after many corrupted filesystems, my linux box would not recognize my board until I rebooted it.. your mileage may vary ...

obsidian dome
#

I suppose I need new libraries....

tulip sleet
#

the filesystem is probably corrupted, so do:

import storage
storage.erase_filesystem()
solar whale
#

rebooted the linux box, that is.

tulip sleet
#

in the repl. that will wipe and reformat CIRCUITPY

#

if you cannot do that at all we have some eraser UF2's

obsidian dome
#

@tulip sleet got it to reformat, now I need to somehow get the files back on it. Can I get the files / folders from someplace online?

tulip sleet
#

@obsidian dome most of the libraries you want are built in to the CPX build, so you don't need to load them explicitly. Do you want a demo program? If not, then just start programming.

#

eg from adafruit_circuitplayground.express import cpx is built in

obsidian dome
#

Working on it. Getting odd behaviour. Trying to figure it out.

manic glacierBOT
obsidian dome
#

OK. seems to work now. Looks like I upgraded about 8 hours too soon. Should have waited for this morning 😃

#

Hmmm. Copying my audio clips onto the board I am getting lots of reboots during the process.

meager fog
#

thats normal

tulip sleet
#

if you do the copies while you're in the repl, it will not restart on each copy

obsidian dome
#

OK. I was getting about 8 reboots per sound file

tulip sleet
#

@obsidian dome gotta be afk for a few hours; good luck; others can help if you have trouble

obsidian dome
#

@tulip sleet Thanks a bunch. Really appreciate the help. I'm trying to get this all set up for a workshop I am teaching.

tulip sleet

@obsidian dome if you don't want to live on the bleeding edge, version 3.1.2 is plenty stable.

Hi, I was wanting to try this QR Code generator on the pyportal: https://www.nayuki.io/page/qr-code-generator-library#python
So I grabbed the the zip file from pypi (https://pypi.org/project/qrcodegen/#files) and copied qrcodegen.py to my lib folder. I tried the "hello world" example (from the first link) and I get the ImportError "no module named 'itertools'". when I try to run it. I checked qrcodegen.py, and I see

import collections, itertools, re, sys

So it looks like it needs itertools, which is built into python. If I went through the steps to convert the script into a .mpy frozen module using mpy-cross , would itertools come with it?

PyPI

High quality QR Code generator library for Python 2 and 3

raven canopy

@shell falcon i'm 99% sure we don't have itertools available in CircuitPython. i'm not even sure if MicroPython has it.

It appears to be impossible to build an atmel-samd target with either CIRCUITPY_PULSEIO = 0 or CIRCUITPY_ROTARYIO = 0 due to hard-coded references to functions in samd-peripherals/samd/external_interrupts.c (causing link errors).

[adafruit/circuitpython] New comment on issue #1642: Linux Ubuntu 18\.04 USB Connection Error

I did a little research on this board. There have been USB problems in the past, though they seem to be related to USB 3.0. Have you tried the USB 3.0 ports, or the USB-C port with an adapter?

I'm suspecting there's something marginal about the USB driver or ports. If you could get some USB traces with wireshark (if that works) or a Beagle USB tracer, then we'd have a starting point for what's going on. Otherwise, I'm not sure we have anything to offer - sorry about that.

@tulip sleet i meant to ask/follow-up on my previous comment about nrfx release disparity. i saw that you brought the fork up to date, but CP is still behind. have you done any regression testing with it? and does it possibly "fix" any of the issues with nrf?

The Feather nRF52840 Express (which is what the binary you mentioned was for) and the same binary. Yes I'm getting a little Blinka icon in the corner and text with that. Do you happen to remember if the plastic that came on the display had a red tab, green tab, or some other color? If not, that's ok.

I think the tab color was meaningful only for the displays sourced by Adafruit, if you get them from anywhere else, that color is pretty much random and doesn't correspond to the display version.

There are two versions of those displays (originally designated as "red tab" and "green tab"), which differ in how the actual LCD lines are connected to the ST7725 chip inside — one starts at the upper left corner and has no interleave, and the other starts 32 pixels shifted (it's centered) and ha...

Thanks for the input @deshipu. That wasn't explained very clearly anywhere I could find.

@rdagger, I'm not loading a full bitmap. It's only displaying the REPL output onto my screen with my code. The board I'm using is a 1.44" 128x128 screen that is very similar to the screen this driver was written for, so I'm not surprised mine is working. I went ahead and ordered the screen you mentioned off amazon and will test it. It should arrive in a couple days. Also yes, I do have access to an osc...

[adafruit/circuitpython] New comment on issue #1657: Fatal exception and reset when 'import ntptime'\.

There seems to be something wrong with the frozen-in version of ntptime. As a workaround for now, try copying the file below,ntptime.py, to the root directory and importing it. I did that and it didn't crash. This is the exactly the file that is supposed to be built in:

I did further testing this morning. I was wrong about the SPI data. The command and data are transmitted. There’s a delay between the command and data that threw off my scope. This delay was not present in the RGB Display library initialization.

Finished the “classic” MIDI UART library. @split ocean successfully tested it on a couple of his unique DIY MIDI controllers. Coupled it with my Range_Slicer library to quantize potentiometer settings into MIDI control and note codes. Was completely distracted by PyPortal projects this week. Customized the Weather Station project and used it as an excuse to dive deeper into CircuitPython coding. Of course, not I have a lot more questions to ask. Thanks again to everyone for their patience.

#

Over the next week I’ll be moving most of my development project archives into GitHub now that I’m dangerously quasi-knowledgeable. I’ll continue to wrap up the test of non-linear Range_Slicer library algorithms and will finally send the PCB off to OSH Park. If PyPortal doesn’t call to me. My weather station needs to play some wave files of our local weatherperson’s glib remarks at appropriate intervals.

Very nice @rdagger! I've requested for a couple display repos to be created. Once that's complete, would you like to package that driver up into a PR? I can help you out if you would like.

Regarding the displayio sample code, I think it's probably outdated. I recently wrote some sample code for the ILI9341 CP driver that could be minimally repurposed for the other displays. It just basically initializes the display and fills the screen red.

Does Adafruit take pull requests for their Libraries? I've found doing a check to make sure self._uart.in_waiting is at least 64 before calling _uart.readline() on line 145 in adafruit_gps.py really speeds up calls to gps.update()

I think before it would call readline() and wait until there is some data before returning

Your experience two comments up is familiar. Windows in particular, and Linux to a lesser extent, do not write all the data and metadata to the drive immediately when you write a file. For Windows, this can take up to 90 seconds, for Linux, it's 10-20 seconds or so. Windows has a long delay only with FAT12 filesystems.

I reallly hope I have a chance to work on a CP project this weekend. It'll be a clock with an unusual analog dial style.

Looks neat!

#

I haven't done graphics with CP yet, so it'll be new to me. I think there are some enhancements in CP4 for that?

idle owl

displayio has a ton of stuff in it. However, at the moment, we can't do GIFs so you'd have to figure out another method.

stuck elbow
#

displayio, but updating the whole screen is going to be slow

onyx hinge
#

the display only goes around twice a day, so it'll be more about wanting to prevent obvious tearing than about getting 60fps

#

I want to do tetris for the hallowing at some point, using the teeth as touch buttons

onyx hinge
#

I think that at least at the register level, RA8875 with the 480x272 screen can do double buffering, but I don't think that adafruit_ra8875 supports it yet based on the documentation.

gilded cradle
#

No it doesn’t. @onyx hinge. Neither does the CP library that I wrote. For that it was a matter of striking a balance between having a huge library with every feature and making it easy to use. If you’d like to give adding it to either library a shot, go ahead and submit a PR.

#

@gilded cradle could a separate lib subclass it to add the double buffer?

#

jelper: good to hear your'e safe, must be never racking tho...

gilded cradle
#

I think it’s a matter of modifying the initialization of the display and adding some functions to switch between layers. I think it only works in low res mode though. Don’t remember for sure. It’s in the data “sheet”.

onyx hinge
#

@gilded cradle Yeah, there's not enough RAM in the RA8875 to do double buffering with the 800x480 screens, except maybe if you work in 8bpp mode instead of 16bpp mode

#

(so far I've only got the datasheet to read, not the hardware)

gilded cradle
#

WRMP 1.5 is fishy

idle owl

You're running 2.0 @stuck elbow

stuck elbow
#

@idle owl that's because it's an old edition and the newer releases have wrong pins for it

idle owl
#

@tulip sleet Fishy how?

tulip sleet
#

I think that string is meant to be human-readable?

idle owl
#

@stuck elbow ah ok. Thanks for trying it! I didn't realise it was added later.

#

@tulip sleet I got the same thing on mine.

tulip sleet

>>> import microcontroller
>>> microcontroller.cpu.uid

from a Metro M0

idle owl
#

bytearray(b'\xf2\x84\x83\xb22C7S 1J\x1c\x10\xff') Feather M4.

#

That's why I converted it to int. FIgured I'd get something out of it. Middle value is 32 and end value is 255 seems to be static for the CPXs.

#

I wanted to figure out if converting to int and then using the first value or something would work.

#

but needed more than a few data points to determine that.

tulip sleet
#

Trinket M0:

>>> microcontroller.cpu.uid
bytearray(b"+6h832KP 1.8A'\x12\xff")
idle owl
#

Shorty!

tulip sleet
#

you could just add up the bytes

idle owl
#

How would I do that? I don't know how to work with bytearrays except to be told they're not good to work with, so convert them to something else.

#

Owait.

1310```
tulip sleet
#

are you trying to get a random seed?

idle owl
#

Yah I think so.

#

I'm trying to use the uid to determine an action on startup. So I was looking for something unique about it to work with. Clearly they're all unique, but I was trying to get away from working with the entire bytearray

#

Adding it up gets away from that. But I still need more data samples to know what ranges or whatever to set the actions to.

tulip sleet
#

you could just do sum(uid) % n, where n is how many alternatives you want

idle owl
#

interesting.

@tulip sleet Thanks! Now I need to try it on a bunch of boards, but the three I have hooked up returned 1 and 2 for % 3.

idle owl
#

Ok thank you!

@idle owl my CPX uid gets 0

so looks good. I was hoping the sum wasn't always even or something like that

idle owl
#

@tulip sleet ok.. OH... right, it'll never return 3. starts at 0. 🤦

#

Ok. Good!

tulip sleet
#

it's a pretty minimal number of characters of program code

idle owl
#

Yep

onyx hinge
#

@idle owl I think you could also try hash(uid)%3

#

it will combine the bytes of uid in a slightly more complicated way than sum() will, reducing any patterns that might exist in the uids

idle owl
#

@onyx hinge Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported type for __hash__: 'bytearray'

@slender iron is there any way to load a Bitmap (not OnDiskBitmap) from a BMP file?

@idle owl try hash(str(buf)) % 3

idle owl
#

Oh nice.

gilded cradle
#

my result was still 1

idle owl
#

Returned the same thing though.

#

Yeah, I'll stick with sum I think.

gilded cradle
#

😃

#

Or you could do something like buf[0] % 3 since that byte varies quite a bit

#

It up to you either way though.

[adafruit/circuitpython] Pull request opened: #1672 flush flash filesystem once a second

This PR adds timing code to flush the flash filesystem once a second (if needed). The interval can be varied by a compile constant.

I think this would solve any remaining file-flushing issues. But there may be other issues causing a hard crash that will corrupt the filesystem if they occur during a write, and this won't fix those.

I have done limited testing. I saw one safe-mode reboot on PyPortal that may have been unrelated to the filesystem.

thanks, I'll see what fits

tough flax
#

So... I'm trying to use the touchscreen on the PyPortal and I'm using @meager fog's SoundBoard example. It works (yay). But I want to use the web to fetch data. The PyPortal initializes the ESP32 and I see that I can use the wget() method. But can I get the underlying connection?

Short version is: I want to fetch things at startup and on certain user actions, but not periodically and I don't want the Portal doing the JSON parsing.

It looks like the wget will get a file and save it... but it writes to the screen which sucks - and I'd rather just get the string (I'm going to parse it anyway).

Is anyone working on something like this?

manic glacierBOT
tulip sleet
#

@tough flax you can use the requests library, which is what wget() uses. It would probably make sense to start with PyPortal and remove all the periodic stuff. Ideally it should be rewritten to factor out the general stuff from the specific use case, but nobody's done that yet.

tough flax
#

I think I could change adafruit_pyportal.py to take in an optional ESP_SPIcontrol object and not re-init it if it is passed in? The assumption being if you

#

Sorry, cut off my thought

marble hornet
#

@slender iron has a bootloader problem been ruled out?

slender iron
#

I don't know why it'd be the bootloader. It doesn't do anything with the spi flash

tulip sleet
#

@marble hornet so you say it wiped the filesystem immediately after you loaded the new beta.5 UF2, or after you used it for a while? I saw something similar: I loaded a new UF2, and it came up in safe mode (but it didn't wipe the filesystem).

marble hornet
#

it booted once, like could see serial with mu, then promptly crashed. no safemode. just renamed as NO NAME and empty

tulip sleet
#

what beta was it running before that?

manic glacierBOT
marble hornet
tulip sleet
#

beta 4 was very touchy about the filesystem. The filesystem could have already been corrupted. Could you try beta 5 for a while and see if it replicates? Thanks.

manic glacierBOT
marble hornet
#

@tulip sleet i tried it for a little and i couldn't save code or reload w/ ctrl-d. the status led would go read and it would freeze. then boot into "HARDCRASH"

#

I mean after you reset the filessytem, with import storage; storage.erase_filesystem()

manic glacierBOT
tulip sleet
#

that will get a fresh CIRCUITPY; then try with your beta.5

marble hornet
#

sure i'll give it a shot, let me push my project to git first and switch back to stock beta5 (i made a dispio less one in the interim)

@tulip sleet I find that normally makes the drive corruption go away.

marble hornet
#

@tulip sleet it did it again. with a fresh erase and the stock beta5 build.

#

hrmmm

#

** i should specify hard crash not wipe

tulip sleet
#

@marble hornet so the sequence was: storage.erase_filesystem(), then load new uf2, then hard crash on startup?

#

was there anything on the filesystem when it hard-crashed?

marble hornet
#

but gui.py was corrupted. insert " saving file " bewtween load uf2 and hard crash

tulip sleet
#

how did you write gui.py? what os and what editor, or was it a command-line copy or drag-n-drop?

#

the crash may not be filesystem-related

I backed out to the previous library

@tough flax Adafruit IO CircuitPython also requires a wifi object init, I've ran into the same sort of thing as you while doing projects. To get around it, I didn't use the pyportal class and wrote a "helper" file for the displayio graphics

when doing git submodule init

tulip sleet
#

@tough flax copy it back, and then erase the filesystem:

import storage
storage.erase_filesystem()
#

@timber mango try git submodule update --init --recursive

#

I have this alias, which does even more:
alias gitsubupdate='git submodule sync --quiet && git submodule update --init --recursive'

#

@tulip sleet that's actually what I tried

#

ah, sync did it, thanks

tough flax
#

Thank you

#

painfully slow to write all those libs back.

#

but it's working

#

was very unhappy

#

Looks to me like it's resetting every file? Every directory? (Super Slow)

#

Don't care - I'm happy

stuck elbow
#

How about this one?

FileNotFoundError: [Errno 2] No such file or directory: '../../tools/Tecate-bitmap-fonts/bitmap/terminus-font-4.39/ter-u12n.bdf'
tulip sleet
#

@timber mango that's a new rsubmodule repo

#

it should be in .gitmodules

tough flax
#

While I wait for this to complete, is the SD card mounted read-write by default on the Portal?

tulip sleet
#

@tough flax yes, because it's not exposed via USB

tough flax
#

Makes sense - got "timeout waiting for v2 card" - too big? Wrong format?

tulip sleet
#

only a FAT formatted card will work. how big is it? 32gb might be too big

tough flax
#

It is a 32G - I have a 16GB that's older, but the only options I have are NTFS, FAT32, and exFAT

tulip sleet
#

fat32

tough flax
#

Formatting from the command line as fat - it was already fat32

#

No SD card found: [Errno 19] Unsupported operation - OK, I'll go hunting for an old card

#

Thank you - that's working ... on to the next issue

tough flax
#

I am of the unfortunate opinion that the current button code (sound board) cannot work with the latest PyPortal code. And I can't fix it before tonight 😕

[adafruit/circuitpython] New comment on pull request #1674: Properly calculate BPP for displayio\.Bitmap

The implementation caps at 8 bit color: https://github.com/adafruit/circuitpython/blob/master/shared-module/displayio/Bitmap.c#L48

I think this implementation may still infinite loop for value counts > 0x80000000 because the minimum value based on bits will wrap around. Do we want to support 32 bit color in the future or is 24 enough? We can cap the number for the API here and leave the above check for the implementation.

this too please

tulip sleet
#

@slender iron are we going to clean up the libraries and remove the try-imports on ga release?

slender iron
#

ya, that was my plan

tulip sleet
#

k, i can add an issue for that in this lib

slender iron
#

k, thanks

My serial breakout arrived a few days earlier than expected.

#

Now I just need some m/f jumpers to connect it to my logic analyzer.

#

I'd like to find the equivalent for USB A m/f, but I haven't seen one yet.

Sounds like a USB extender, those are common enough.

wraith tiger
#

Yeah, but I need somewhere to attach hooks/probes to.

I guess I could strip the wires in the middle of an extender cable.

@gilded cradle I hit "Comment" prematurely, so look again at the github issue thread for more steps. I edited the comment.

gilded cradle
#

Ok, thanks for the heads up

#

I'll go through those steps when I have a moment just so I can get more familiar with the process.

tulip sleet
#

i'll be out most of the evening (ET)

gilded cradle
#

Ok, I can always just leave you a message if I have a question.

#

😃

tulip sleet
#

thanks!

gilded cradle
#

Or somebody else might be around too

#

Most likely though, I'll figure it out I usually do.

tulip sleet
#

you may or may not grow to like gdb 😃

gilded cradle
#

We'll see

raven canopy
#

i have. display '<file>'::variable is my new fav command. never got things like that to work in Atmel Studio. 😄

gilded cradle
#

I haven't used Atmel Studio much. I've mostly used debuggers for other languages than C.

raven canopy
#

it has its usefullness. it was nice to have a quick visual representation of registers and their values. having a project linked to the ELF as well; still haven't been able to figure that out on SEGGER Embedded Studio. I did read in the segger forums that they (segger) have heard that Microchip is not going to maintain AS going forward... 😑

gilded cradle
#

Then it sounds like GDB is the way to go

slender iron
#

I use gdb myself

Is anyone aware of an issue using the OLED FeatherWing and the GPS FeatherWing together in CP 4-beta.5?

#

It doesn't refresh if I leave line 28 uncommented, it will update without that line, but of course it becomes a series of white boxes lol

I'm pulling my hair out over here lol what is this thing doing?

#

@solar basin The live streams are happening, so it might be a bit before anyone responds.

solar basin
#

Oh duh! lol

stuck elbow
#

@solar basin what do you mean by "won't update" exactly? Any errors?

solar basin
#

The screen does not change

stuck elbow
#

do you get any messages in the console?

solar basin
#

No

#

It prints just fine

manic glacierBOT
stuck elbow
#

what if you draw a smaller rect?

solar basin
#

I'm trying to clear the screen

#

I can draw to the screen, but the GPS data is not updating

#

If I turn on debugging in the GPS module, it stops printing data after the first second

stuck elbow
#

maybe you can try with a simpler program first? try to write the minimal program that demonstrates the problem?

#

keep removing lines until it works?

#

and then add back the line at which it stops working

solar basin
#

Yeah, I've been doing that for hours
