"TFT Backlight
- not all Feathers have PWM and also most of the time you don't need to do a lot with the

raven canopy
@tidal kiln you around?
idle owl
He's not around this weekend.
raven canopy
k. the yellow isn't a lie...techincally. ๐
but, i can put the question to anyone that wants to weigh in.
how would you handle this:
>>> fram[0:4] = bytearray(b'length>greater_than_slice')
>>> fram[0:4]
bytearray(b'leng')
>>> fram[0:15]
bytearray(b'length>greater_')
currently, the write length is determined by len(value), and not the length of the slice. So...
- raise an exception warning that value is longer than the requested slice
- don't raise an exception, and ignore writing anything beyond the length of the slice
๐ค
raven canopy
i reject that sentiment...
idle owl
Actually you may be right, I guess rereading it, it's not as confusing as I thought.
I'd say raise an exception, all the LED libraries do.
tepid sapphire
hi, i have here sample of NINA B3 to test the CIRCUIT PYTHON ๐
idle owl
But the LED library usage of slicing is really the extent to which I've done anything with slicing. So my thoughts on it may be scoped by that.
raven canopy
i am leaning towards one of them (trying to keep my bias out for now). thanks @idle owl for pointing towards some standard expectations; i was leaving that out of my thoughts.
idle owl
I don't know that I would consider that a standard... it's simply the only example I know of. But that's good if it helps.
raven canopy
@slender iron is circuitpython-build-tools ready for another release?
slender iron

raven canopy
haha. well, version & readme fix PRs are merged. so...i'll get on that i guess. ๐
unless you want that refactoring done before release.
bronze shadow
Just wanted to make sure that I understand this. uart can only be used on the TX and RX pins as those are the only accelerated pins and there is no bitbang version of it. Is this correct? I'm on the Itsy Bitsy M4
raven canopy
@bronze shadow i think you can use any pin with an available SERCOM. i was able to do this on a Feather M0 Express:
uart = busio.UART(board.D11, board.D12)
TX/RX are D1/D0 on that board...
bronze shadow
Alright. Thank you. I was a little confused as it was under the hardware accelerated part, but that makes sense. Is there an advantage to using the TX and RX then in any way?
raven canopy
although, since the Itsy uses a smaller package SAMD51..it may have more constraints.
Is there an advantage to using the TX and RX then in any way?
I wouldn't say so, since it's all using the SERCOM pads under the hood. But, someone smarter than me may have a better answer.
bronze shadow
Alright. Having dedicated pins may just be a guarentee of 1 free lane to do that in maybe. The help is massively appreciated as always here.
bronze shadow
So just tested to see if I could use RX as TX and vice versa, and that's definately not possible. I should probably pick diffenet pins?
TX connected to TX, RX to RX, but defined as flipped on one board.
raven canopy
did it give you an Invalid pins error? or is it just not working?
bronze shadow
Just not working. Checked connections, and no issues physically.
I had them reversed and it was also working fine (tx to rx, tx to rx) But for reasons I can't explain, I need to connect to the same pins on both sides, and have them reverse role
I can use SCL and SDA if those are better pins
raven canopy
i'd have to step through the UART periph's SERCOM assignment to see if there is some collision going on, though the UART constructor looks like it should catch it...
bronze shadow
Thought it finally errored, but the usb cable was pulled. Oops.
raven canopy
i need to order more M4s. only have a Metro... like i said earlier, the Itsy M4 may have more constraints because it uses the "smaller" SAMD51G (vs SAMD51J on Metro). the Itsy schematic has a note "SERCOM3: UART", but i don't see anything code-wise that is limiting it to just SERCOM3. ๐คท danh or tannewt would likely have better answers than i

hey, my st7735r in the feather display w/ seesaw is only displaying white, i'm using the stock rgb library and it is only showing white. however if I read a pixel it gives the sent color
any pointers? I'm out of things I can think of to try to fix it, Any and All help welcome! thanks either way
here is the code I am running

@marble hornet hard to say without knowing more but that has a hardware-feel to it. I'd start by hunting for shorted or disconnected pins, make sure the CS pin is behaving, and that everything is wired up correctly

@solar whale Aha! The issue also occurs on a Sparkfun board AS7263
thanks btw! this gives me hoep
marble hornet
So i went back through and checked every connection and rewetted all thejoints. no change. I can only guess it is a code problem. do you know how to scan an i2c bus? im trying this: ```>>> import busio
from board import *
port = busio.I2C(SCL,SDA)
port.scan()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: Function requires lock.``` but it is not working. thoughs? @lime trellis ?
raven canopy
@marble hornet you need to lock the I2C bus:
>>> import busio
>>>from board import *
>>> port = busio.I2C(SCL,SDA)
>>> port.try_lock()
>>> port.scan()
@raven canopy thanks, will try
raven canopy
also, it will need to be unlocked afterwards. port.unlock()
marble hornet
what does locking and unlocking do ?
raven canopy
ensures that only one object & slave is being communicated with. otherwise, with multiple slaves on the bus, the bits could get smashed.
example would be hard to illustrate, without some serious commenting or visual aids.
marble hornet
while the master actaullly talks to one more than one of the slave thinks it is being talked to ?

@upbeat plover ok -- finally some progress with bitmapfont. Now to figure out why this works and my previous attempts did not. Thanks for all your work on this!
solar whale
@upbeat plover one thing I still find confusing is the screen orientation and how "x","y" are used in your etch-a-sketch example. If the joystick is on the left, AB buttons on right -- I would call up/down Y and right/left x. Just my bias ๐ Also, why do you have the 24 pixel offset for the x location?

anyone know an alternative to calling pack on every pixel in a bitmap to pack a bitmap's worth of pixels?
hmm... maybe I can just write the packed version to disk...
marble hornet
here is the library, instead of 'st7735' as the lib name it is 'st7735r' and the class name is ST7735R and it supports x_offset and y_offset when you make an instance, i found 24 right x_offset to make the display work, and Rotation = 3 should do the trick. (i don't support negative input for rotation yet but i will soon)
@upbeat plover
pastel panther
@marble hornet is this a change to adafruit_rgb_display?
marble hornet
it isn't perfect. if you want it to work you need to put it in a folder called tg_modules, and put this next to it:
@pastel panther to the st7735 and rgb part of the adafruit rgb display
pastel panther
you should submit a PR if you think it would be useful
marble hornet
@upbeat plover ^^^^^^
@pastel panther , it isn't quite there yet (i think) b/c it doesn't work for all of the displays and my text method is occasionally buggy

I think I missed something a little while ago -- the Circuit Python bundle .zip now contains a (nearly) empty lib directory as well as the one with all the libraries in it beneath another directory named for the build. Is this how it's supposed to be?
raven canopy
@split ocean that was my fault. i missed updating the directory for the README when I added example bundling to the script adabot runs. the fix has been made, so it shouldn't occur going forward.
split ocean
cool, thanks!
raven canopy
@split ocean other than the snafu, what do you think of the bundle changes? (also going forward, mpy versions will be 3.x and 4.x; no more 2.x)
split ocean
is the other main change that there is the examples directory?
(point me at a release notes if that's easier!)

raven canopy
for setitem? yeah. i just need to push the update. was kind of waiting for any additional answers to my long scrolled past question. ๐
switch to working adabot took my attention, too ๐ค
hmm...and just before i push, another question.
which is better behavior:
if val_len > (slice_start + slice_stop):
raise ValueError("Supplied value length is greater than memory slice.")
or
if not val_len == (slice_start + slice_stop):
raise ValueError("Supplied value length does not match memory slice length.")
i could be un-lazy and test...but, only just started โ # 2.

pastel panther
๐ฎ
pastel panther
kattni believes in me!
tidal kiln
@raven canopy seems like the two cases to deal with are:
- slice smaller than value list
- slice larger than value list
both could be generalized to:
- slice size != value list size
pastel panther
whenever someone says 'tada', this sound, at this bitrate plays in my head
https://www.youtube.com/watch?v=QDUv_8Dw-Mw
idle owl
I kind of want to record me saying it as lackluster as possible and send it to you to ruin your brain association.
raven canopy
@tidal kiln yeah. originally i realized that you could write beyond the slice. then after handling that, slice len > value len, popped in my head. i feel handling it as a generalized case works...
so many memories of Win3.1 tada...
tidal kiln
it also seems a little redundant to need to specify the slice and also provide a list of matching length.
i wonder if we should just do something like:
fram[start] = some_list
so...don't handle/allow slice.stop?
>>> fram[start:stop] = ["Make", "coffee"]
Traceback:
I'm sorry Dave, you can't do that.
of for anything other than an int.
set index to 0x42
fram[index] = 0x42
set memory starting at index to hello
fram[index] = b'hello'
you're not allowing any fancy slicing of where things get written to on the FRAM - which is fine
idle owl
@raven canopy finally is a thing? I didn't know that.
raven canopy
@idle owl it is. very handy too!
@tidal kiln i can accept no slicing on writes. chalk it up to over-zealous inclusion of coolness.
also...less code! haha
tidal kiln
i'm not sure what the application would be, and i think dealing with it would add too much code
so the basic pattern is simple:
fram[index] = value
and behavior changes by simply checking what value is. index can only be an int and is taken as the starting address for the write.
we could say value has to be a list of some kind, even for a single value, but then users couldn't do this:
fram[index] = 0x42
they would have to do this:
fram[index] = b'0x42'
which i think looks a bit awkward for beginners
pastel panther
you gotta love when you come to your bench in the morning to continue your work from the previous night and nothing works anymore ๐
idle owl
been there entirely too many times.
tidal kiln
@pastel panther wait another 24, then it will invert again
raven canopy
@tidal kiln agreed. and with all of this setitem change, i believe i can actually drop the separate _write funcs. for both I2C and SPI. already handling isinstance for int and mutables...just need to marry them.
tidal kiln
what i'm suggesting is a simplification from what you currently have, so if it helps clean up the code for the classes, then extra points
tidal kiln
can you think of a reason to need to be able to use a slice for the index?
idle owl
@pastel panther llol
raven canopy
@tidal kiln not precisely. and without extending slice.step, it makes even less sense to allow it.
pastel panther
now if I can just figure out how to flip these bitmaps into the correct order without using up all the memory on the m4...
tidal kiln
@raven canopy i'm not either. currently.

I just found myself wondering if a board I have is running 4.0.0 Alpha 1 or Alpha 2. Is there/could there be a way to tell, say something in the INFO_UF2.TXT file?

and with wrap around, guess the list could be larger than the memory and it just keeps going round n round, but seems like a better idea to only allow len(value) <= fram.size

hey @idle owl What do you think about the idea of a "here's what's not working/is changing" in 4.x" mini release notes?

I like the idea, I question where to put it. Release notes make the most sense, but I feel like it should have been included already, why wasn't it?
tawny creek
Currently, to make text appear on an SSD1306 via Circuitpython you'd have to follow this tutorial: https://learn.adafruit.com/micropython-displays-drawing-text/software (some might think this will not work for Circuitpython), update a local copy of: https://github.com/adafruit/micropython-adafruit-bitmap-font to use struct vs ustruct
whats the best way to approach? https://github.com/adafruit/micropython-adafruit-framebuf/pull/4#issuecomment-368594803 suggests to do this via micropython-adafruit-bitmap-font (see also: https://github.com/adafruit/micropython-adafruit-framebuf/issues/2)

@tawny creek just to clarify, the adafruit_circuitpython_ssd1306 driver imports framebuf so I guess you have to also install the python version of framebuf first.

thanks @solar whale I haven't run into this other than @umbral dagger learn guide.
no need for a special cut.
solar whale
@tawny creek this works ```from board import SCL,SDA
from busio import I2C
import time
Import the SSD1306 module.
import adafruit_ssd1306
import bitmapfont
i2c=I2C(SCL,SDA)
display = adafruit_ssd1306.SSD1306_I2C(128, 32, i2c)
display.fill(0)
display.show()
bf = bitmapfont.BitmapFont(128, 32, display.pixel)
bf.init()
bf.text('Hello, World!', 0, 0, 1 )
bf.text('Hello, World!', 0, 10, 1)
bf.text('Hello, World!', 10, 20, 1)
display.show()
time.sleep(2)
display.invert(True)
time.sleep(2)
display.invert(False)
time.sleep(2)
display.fill(0)
display.show()
yay was using:
# Define bitmap font bf = bitmapfont.BitmapFont(15, 7, oled.pixel) bf.init()
doh
solar whale
i recall doing that in the past
tawny creek
thanks for looking into this, the guide could be updated to include this ๐ค
tidal kiln
@idle owl should we enable travis for the ADXL34x repo?
solar whale
yes- bitmapfont.py should be modified and re-relased and the guide updated if we are going to use this as a work around until displayio is available. I think the intent is not to encourage use of framebuf.
idle owl
@tidal kiln Probably
tawny creek
@solar whale awesome gotcha!

I can access my CircuitPython devices (Trinket M0, Gemma M0, CPX, Itsy Bitsy M0) as CIRCUITPY on Win7. Why can't Ifind it on my Android phone and tablets?
I get the USB notification Unsupported ATMEL USB drive
(using just one of them for the other side) when I double-reset, I can get the TRINKETBOOT drive on Android but it shows instead as /storage/0042-0042
marble hornet
@upbeat plover thank you, I'm flattered
dusty plinth
Anyone know anything about the CircuitPython/Android problem?
solar whale
@dusty plinth as I understand it, not all USB devices are the same. Someone more knowledgeable will have to provide details, but I donโt think it will work at this time.
tulip sleet
@dusty plinth The problem is that Android doesn't have support for the FAT12 filesystem, which is the tiniest (<16MB) variant of FAT -- originally used for floppies, etc.
there are one or two apps that do support FAT12 -- I'll try to dredge that info up
fathom basalt
@dusty plinth There's some discussion of issues mounting CircuitPython drives on Android, here: https://forums.adafruit.com/viewtopic.php?f=60&t=127765&p=636547&hilit=android+circuitpy
tulip sleet
dusty plinth
why does the other side (TRINKETBOOT) work?
shouldn't they both use the same filesystem (simpler than handling 2 filesystems in the firmware)?
tulip sleet
I'm not quite sure why the UF2 filesystem works, but it's a completely different codebase, and the UF2 ...BOOT drives are "fake": they just simulate a filesystem: you can't store arbitrary files on them.
I've thought about having our FAT12 filesystems report as FAT16 with a very large number of bad blocks (you can mark blocks as bad), but haven't tried that yet.
raven canopy
@tidal kiln during a "final" review before pushing FRAM updates, i realized that changing read() to read the entire buffer before returning the value (Scott's suggestion) breaks slice.steping. thoughts? drop step, or read byte-by-byte when step is provided?
tidal kiln
@raven canopy i'd say drop it for the initial release. it's sort of a fancy feature that can be added later if use cases for it start showing up.

I submitted a PR to micropython-adafruit-bitmap-font to add the test for struct vs ustruct. It seem like this may get more use now since framebuf is not available. Anyone using it has to modify it to import struct as ustruct so this will simplify. I can't assign reviewers so please take a look if you are interested.

Hug report again to tannewt for putting up with my increasingly-in-the-weeds questions and bug reports. Also a shout-out to arturo182 for reviewing my PR 1286.
What's new: finished a huge refactor of the KMK keyboard firmware project (I can now max out my personal typing speed ~100 WPM rather than it getting tripped up at 50WPM or so ๐), and added a bunch of neat more-advanced functionality to it. Found and reported a possible deadlock (and sometimes soft-brick) in CircuitPython (issue 1283). Finished my pinout/"port" of CircuitPython to MakerDiary's NRF52840 MDK board, submitted as PR 1286. This week: going to finish PR 1274 (modgzip/uzlib stuff), hopefully really make a repro scenario for 1283, and even more hopefully add zip module support once 1274 goes through.

weeds -- clarify 3.x vs 4.x bundle?
inland tusk
I have no staatus updates
idle owl
@solar whale It turns out the mpy-cross version has coincidentally matched the CircuitPython version - i.e. the current version is 3.x which matched CP 3.x. Well, the current version is still 3.x, however, the coincidental association has been made in people's minds, so we've made a 4.x bundle to match CP 4.x, so there is no confusion as to which bundle to use with which version of CircuitPython.

The midi stuff will help me with my new project
fierce girder
I developed these changes using an Adafruit BME280 breakout board wired up to P9.19 (SCL) and P9.20 (SDA) and the Adafruit_CircuitPython_BME280 library
Please note that this is just preliminary support. I2C support in Blinka on BeagleBone Black requires hard-coded workarounds in the following libraries.
- Adafruit_CircuitPython_BusDevice
- Adafruit_Python_PureIO
I still need to resolve the root cause and find an acceptable solution.
stuck elbow
fierce girder
The biggest challenge for me right now is related to:
Adafruit_CircuitPython_BusDevice
The current behavior is to do a blank write to the I2C address: i2c.writeto(device_address, b'')
This causes a write error on the BeagleBone Black

@keen maple PNG files are harder to read with microcontrollers, and I don't even know of any Arduino libraries to do it. CircuitPython, being newer and less well-known, almost certainly doesn't have any.
BMP files, on the other hand, are fairly well known. And I know there's some support for loading of them.

@cunning crypt Cool, PNG to BMP conversion is easy to do before it is loaded onto microcontroller, so I will have to look into that. Thanks!

Oh hey, @raven canopy wondering if you could add an optional thing to Adabot to run a check that compares all Adafruit_name libraries to Adafruit_CircuitPython_name libraries and spits out the ones that don't have a CircuitPython repo? i.e. checking to see which hardware has an Arduino library and doesn't have a CircuitPython library.
No idea what would be involved in that.

trying to clean up a memory leak at $DAY_JOB but instead it turns out I wrote an infinite loop .. well .. infinite until it exhausts RAM+swap anyway, since it was also leaking on each loop. ๐ข C++ is hard.
raven canopy

cunning crypt
@onyx hinge So, you tried to solve a memory leak, and caused another?
onyx hinge
@cunning crypt that's right!
idle owl
It was a leak leak.
cunning crypt
"This leak won't be a problem anymore."
raven canopy
@idle owl should be doable. may start bumping API request rate limit though. being a paying org, the rate limit is high, but i'd like to look out how it can be structured to minimize requests so it doesn't interfere with normal adabot requests.
idle owl
@raven canopy When I Say optional, I mean seriously optional, as in you have to explicitly ask it to run. I'm not sure it's worth having it run every time.
cunning crypt
@raven canopy @idle owl Realistically, it would only really have to be done once. Get a list, and then you can go from there.
idle owl
Another CLI option that includes it.
@cunning crypt Well we could miss one in the future and the check would be handy to have
Run it every so often.
cunning crypt
True
raven canopy
yeah no, i got that. but some of the rate limits are daily reset. iirc.
idle owl
Wait, is that the blah checks left this hour thing that it shows when you run it?
raven canopy
yep
idle owl
Ah ok
raven canopy
i'd have to look at it again though. the rate limits are "dependent" on the query i think.
raven canopy
fooey. Travis wants another commit to run the commit i pushed last night while GH was down. ๐ฆ

hmm. that was a half GH fail. i was going off of code...which doesn't match the local code for that commit.
so...my fork shows the correct code on the commit. the adafruit repo show the commit hash...but not the updated code. ๐ต
tidal kiln
weird. something must have gotten out of sync during the anomaly.
raven canopy
correction: the PR shows the correct code as well. but, when you open the commit link from the travis run...its wrong.
this is so confusing. dinner...then Travis battle. โ
tidal kiln
@raven canopy ping me if you need help when you get back to it, but i'm also not sure how it got to be like it is
raven canopy
i might try the empty commit trick in Dan's link... looks like travis is out of sync on the commit tree.

here is best. uf2 is a bootloader only thing
I don't know what you mean "outside the bootloader"

you guys need to look at @marble hornet 's RGB font and ST7735R it works great, the rotation feature is needed for both miniTFTwing and the hallowing display

@upbeat plover think it is worth doing a pull request?

But it is only for the st7735r
upbeat plover
well if you could get it for st7735 too then the hallowing will work right aswell

steel vale
Hello, has anybody had their device stuck in read-only? My HalloWing CIRCUITPY is trapped and I can't modify it.
tulip sleet
@steel vale this is usually becuase the filesystem has become corrupted. See https://learn.adafruit.com/welcome-to-circuitpython/troubleshooting#circuitpy-drive-issues-18-13
steel vale
Yes, I tried copying the python file to wipe the drive and I can't because it is stuck in read-only.
tidal kiln
can you access REPL?
steel vale
let me see
btw I'm not using Mu because there is an SHA mismatch error right now when trying to install it. I'm hoping they'll fix it, soon. I'm using sublime and arduino ide
Arduino says it's connected to the serial console
@tidal kiln I've connected on the REPL
tidal kiln
manic glacierBOT
steel vale
Ah, the REPL isn't responding to anything - crap
tidal kiln
@steel vale you're connecting to REPL through the Arduino serial console?
steel vale
No, regular linux terminal
tidal kiln
do you see the REPL prompt?
>>>
I just tried booting the HW as HALLOWBOOT and was able to put the latest .uf2 on it. Still, when it comes back as CIRCUITPY it's read only
No >>>, when it set it up it's just blank.

steel vale
Got it. Did it just become corrupted or something?
tidal kiln
possibly. hard to say. what was main.py?
steel vale
It was just a sample program to use neopixels that I was modding
tidal kiln
you said you were using sublime - was that to edit files directly on the CIRCUITPY folder?
steel vale
Yes
but
I think what did it was trying to unpack the zip with the libraries and examples.
I started having problems after that.
tidal kiln
how were you unpacking the zip?
steel vale
I followed the instructions to do it locally
slender iron
@solar whale added you as a collaborator to bitmap font
steel vale
The instructions for using the circuitpython bundle could use a little more explaintion
manic glacierBOT
tulip sleet
@steel vale feel free to open an issue on the Bundle repo or post in the forums. We're interested in what stumbling blocks you come across.
tidal kiln
steel vale
Oh yes, there are lots of them. I can't seem to set this up correctly. The instructions are very vague and they are not in order.
It's becoming very frustrating not being able to set up the libraries.
@tidal kiln Yes, as well as the ones on the github. Unfortunately, the zip contains a libraries folder full of empty folders. When I try to use git submodule add (in hopes of filling the empty folder) I just get a response saying the address isn't a repository.
tidal kiln
hold on. let me check things. the layout of the bundle is currently being changed. so things may be a little out of sync with the guide.
did you download?
adafruit-circuitpython-bundle-3.x-mpy-20181019.zip
steel vale
yes
steel vale
Hahaha, that explains everything
tidal kiln
it's a work in progress, and right now it's a little broken
steel vale
I know I can't build it in the virtual environment or I'll fill up the drive
tidal kiln
the goal is to have the examples included along with the libraries in the bundle
what you want is in that zip file though
you want the lib folder under build_adafruit_circuitpython_bundle_3.x_mpy_20181019
steel vale
I unzipped it and the folders were empty
solar whale
@tidal kiln @idle owl I tried to release micropython-bitmap-font but the mpy-cross fails since it was originally set up for micropython. Can you see if there is a simple fix to its .travis.yml that will allow it to build -- It can use the circutpython mpy-cross. Should we kludge somehting to get a .mpy into the release or do you want this to get made "proper" for CircuitPython.
tawny creek
will this library be needed when displayio is fully implemented? @solar whale
solar whale
@tawny creek I'm not sure. If not, then it's not worth a lot of effort.
idle owl
Scott would know. If it is needed, I would say we should do it up proper.
solar whale
I agree in the long run -- is there an easy way to get a .mpy out there without that?
tidal kiln
@steel vale i just looked and i'm seeing content.
idle owl
That I don't know. Make it locally and manually upload it? That won't help if Travis is having issues with it though.
solar whale
If not - should we remove the release until it is fixed?
solar whale
I won't be able to work on circuitpythonifying it until the weekend and I'll likely need help getting it set up.
tidal kiln
@steel vale you're downloading a zip of the repo, not the release zip
download zip from here:
https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases

I DL'd the only .tar.gz there

not the source code

solar whale
@slender iron will bitmapfont.py still be used after displayio is implemented. It was originally built for micropython and travis is not happy with it. Trying to determine how much effort to put into it.
slender iron
I'm not sure. I wouldn't put time into it though
my hope is to support ttf on the board
solar whale
sounds good -- we
slender iron
but may have the loader cache data on the fs
solar whale
we'll do the minimum necessary to get it released.
tidal kiln
@solar whale i haven't actually dealt with that directly before, but the lines that need changing seem obvious
- git clone https://github.com/adafruit/micropython.git
- make -C micropython/mpy-cross
- export PATH=$PATH:$PWD/micropython/mpy-cross/
OK -- if I update .travis.yml do I do another PR then a new release?
fluid helm
Hey @idle owl, do you think it's worth me writing a learn guide on EduBlocks for CPX?
solar whale

idle owl
@fluid helm Yeah! But run it by Mike since he's the Learn System Gatekeeper ๐
That would be a great way to get it out there though, and I think it's perfect for a Learn guide
fluid helm
Cool, is he on Discord?
idle owl
Yeah but email is best for him, he's not on right now.
fluid helm
cool, thanks!
tidal kiln
@solar whale i think so. a PR would be needed to change .travis.yml. then when everything is happy, a release.
solar whale
@tidal kiln unfortunately, travis did not complain until the release -- it does not build the .mpy until then
is there a way to just drop the .mpy and font5x8.bin file into the release ?
idle owl
You can upload assets as far as I know.
solar whale
@idle owl is that acceptable?
idle owl
sure I don't see why not. For now it works, worst case we delete the release or the assets later.
solar whale
ok done ๐
When I have more time, I can play with "fixing it" or anyone else is welcome to ....
@idle owl thanks -- sorry for taking the "easy" path but I think this gets us where we need to be for now.
idle owl
Nah it's all good. No point in doing a bunch of work to have it deprecated in a couple of weeks.
Better to get it working for now and deal with it when we know what will actually need to happen
upbeat plover
how do i fix my hallowing? some code has it stuck, i cant even connect to it with PuTTY
I am able to load it into bootloader but changing versions doesnt fix this issue im having... do i need to load something on it in arduino?
idle owl
If you can't get to the REPL, you could try loading something Arduino on it, but that typically doesn't erase what's on there. So usually when you load CircuitPython back on after Arduino, your code is still there.
upbeat plover
im gana try "Adafruit SPI Flash FatFs Format Example"
in arduino and see
no luck so far
i got it to this point but no luck after ```Adafruit SPI Flash FatFs Format Example

There were special eraser files made for earlier boards, but we haven't done them in a long time because of the way to erase the FS from the REPL. They won't work on the Hallowing as far as I know, unfortunately. There's also a way to make a special build of CP that does something to stop the code from running and allow you to delete it... But I don't remember how to do it. Dan did it for me the one time I needed it. And it wasn't for Hallowing, so I don't have it sitting around to give you.

Do you know if anyone has tried to do something like sqlite on adafruit devices?

@velvet badger there's not really enough memory for that. The sqlite library is like half a megabyte. You might want to look in to the RPi Zero, etc.

@tulip sleet Where would one look to see what of cpython is and is not available in CP? I'm wondering about pickle
tulip sleet
there are very few libraries available. There's a library list in RTD, maybe in the micropython rtd
we have most of these, but they are mostly renamed from "u": http://docs.micropython.org/en/latest/library/index.html

I'm taking a stab at moving the samd51 to tinyusb
have you thought about enabling for more dynamic allocation of descriptors and buffers?
gentle bronze
It is up to application, tinyusb only take the pointer to the descriptor
slender iron
where is it passed in?
gentle bronze
there is device driver porting for samd, let's me check if I have a samd board, and run a simple example in my repo first before applying it to the huge code base of cpython.
slender iron
there is work to port it already? is it on github?
slender iron
ah, its passed through global state. I expected it as a function parameter
gentle bronze
app can change the pointer anytime it like, but better not within the enumeration progress
slender iron
right, that works for me
I really like the fifo that tinyusb has
the buffer management in asf4 is super gross

I haven't work with samd usb controller, but that shouldn't be too much issue to have a proof of concept demo. I will start some work on samd port soon enough.

vale zodiac
Can anyone explain with any reasonable ease why an input series resistor before an LDO drops the input voltage? I can't seem to wrap my head around why the LDO itself acts as a resistor to ground - the numbers in sim don't make sense to me.
solar whale
Always happy to get more stuff!
Why would a resistor not drop the input voltage?? I think I misinderstand the question
vale zodiac
input -> 4ohm -> LDO -> output... I guess I just don't see why the voltage is being divided. I see why the resistor will have a current pulled through it. I see why it's not exactly efficient. I see why the LDO will have to pull a little harder. But I don't see a voltage divider
solar whale
there will be a votlage drop across the 4ohm resistor.
vale zodiac
Yes, I agree there will be. But why, and by how much?
solar whale
V=IR -- 4* current
raven canopy
V=IR. As resistance increases, voltage decreases.
vale zodiac
I of the LDO's Q, or I of the LDO's total pull on the other side?
solar whale
if you pull curreent through a resisto it drops the voltage by I*R
tulip sleet
The LDO is not a linear device; it can't be modeled just as a resistor, since the "resistance" will vary based on what's happening at the output. It consumes some current on the input side to act like a voltage source on the output side. The current consumed depends on the current on the output side but is not the same. It will waste some as heat.
vale zodiac
So total pull on the other side... Anything that is being pulled through the resistor - except my stupid sim doesn't show this. If I sim up a basic LDO, and pull an LED with a 100ohm, the voltage drop is X on the input side. But if I increase to a 200ohm on the output side, same voltage drop on the input side. Makes no sense to me
Hmm
So 14V in, 4ohm series, total pull is .300mA, should be a 1.2V drop to 12.8V, ya?
slender iron
mind moving to #help-with-projects ? this doesn't have to do with circuitpython
tulip sleet
You can calculate its "resistance" for a static load on the output side, but
raven canopy
Note: ahhh...tannewt beat me to it.
