Does the PyPortal http://adafru.it/4116 have any ordering gotchas such as "I wish I'd ordered an SD card to go with it!"

@timber mango Not that I've had - i've only sent data over wifi with it.
timber mango
@prime flower Thanks, I apprecate it! I don't have the time to research this at the moment but it looks like a good time to grab one before they disappear. ;)
Arduino-friendly and SAMD51 is usually all I need to know about a thing. ;)
tidal kiln
yah, you can just plug in a USB cable and start using it right away, so anything else you might want (the stand, JST pigtails, etc) you can get later if you want
timber mango
The 8 MB flash is common to NeoTrellis M4, PyPortal .. any others? I thought we were 2 MB SPI flashROM throughout, or was NeoTrellis M4 revised since I got mine?
scarlet maple
@timber mango I immediately went and got an SD card for mine. And the ribbon cable to the display is really touchy on mine, as mentioned on the first FAQ at https://learn.adafruit.com/adafruit-pyportal/pyportal-hardware-faq . No idea if that's been improved on this batch.
timber mango
@scarlet maple thanks! What use did you have for an SD card in this context?
scarlet maple
https://github.com/mikerenfro/iot-office-door-sign -- needed somewhere to download web content to. Could use the flash with some config change, and might be able to just store the JSONs in a string now, but didn't think that was an option at the time.
timber mango
Yeah those are good gotchas. That type of connector always seemed fussy to me, but they've been around for quite some time.
Yeah I was working on a filesystem for the QSPI flashROM but I don't remember how far I got with that. Someone else may've already solved that. I just don't remember.
All I remember was an offhand remark that one could kind of ignore that it was QSPI and use the existing hard wiring for legacy SPI work, to good effect.
crimson ferry
@timber mango Grand Central has 8MB (but no Wi-Fi).
meager fog
@timber mango you dont need an sd card for any of the projects - thers' onboard 8mb storage

For circuit python is there a thread, post, learning guide to learn how to "multi task" a circuit playground express?
I am looking to "interrupt" an action with another action in my little crickit rover bot.
Looking for something similar to this guide
Since I am learning python too I am guessing time.sleep() is just like saying delay()

@raven canopy could add a optional parameter to cpx audio change how load sounds are played, but only 3 settings
def _sine_sample(length, volume=None):
if volume is None:
volume = 0
elif volume is high:
volume = 1
elif volume is low:
volume = -1
else:
print("options are 'high', 'low', or 'None'")
tone_volume = (2 ** 15) + volume
shift = 2 ** 15
for i in range(length):
yield int(tone_volume * math.sin(2*math.pi*(i / length)) + shift)

I've been wondering if the NodeMCU V3 (ESP32) is supported by circuit python.

@shy elm the support is dropped in 4.0, but should work with 3.x

@raven canopy What is a PyPi and why did it choke on the mpy thing mentioned in https://github.com/adafruit/circuitpython-build-tools/issues/29#issuecomment-490268580
raven canopy
hehe. circuitpython-build-tools is deployed to PyPI as a library, then is installed with pip by eacy library and the Bundle repos' CI to bundle the files. there are some things that are difficult to test before its deployed to PyPI, and we couldn't get it to act right today. It was causing a serious backlog of PyCon sprint PR failures, so we reverted it for now.
simple pulsar
Oh, that PyPI - I thought someone had made a board called PyPi - it didn't seem like a wise name.
trim elm
Does anyone know if the decimal library is implemented in circuitpython?
simple pulsar
Is the https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases/download/20190507/adafruit-circuitpython-bundle-4.x-mpy-20190507.zip library ok then? I had a glance inside and it seems to have what you'd expect
Was it #29 or #30 or is that still unknown?

raven canopy
@simple pulsar that one should be good.
simple pulsar
@raven canopy thanks, i'll mention that one in the guide I'm writing explicitly for now, and then revise it when it goes out permanently
raven canopy
sounds good. that was one reason i reopened that issue; didn't want anyone thinking it was fixed for perpetuity..
tulip sleet
@trim elm Nope, no decimal, sorry. We have longints, as you'd expect.

Are there instructions for running the tests? I tried cding into tests and ./run-tests but I got this exception: FileNotFoundError: [Errno 2] No such file or directory: '../ports/unix/micropython': '../ports/unix/micropython'
tulip sleet
@frigid cloak the tests only test the micropython language core, so most of the time they don't provide the coverage you'd need. Check out a travis build for how the tests are run. I very rarely run the tests by hand.
they are only run on the unix build, usually by micropython-coverage
(which is a build that turns on all the features so they can be tested)
frigid cloak
Okay. Though earlier I was messing with the REPL which I'm assuming the tests probably do cover?
tulip sleet
@frigid cloak yes there are some simple tests of the repl. I'm working out how to run the tests by hand.
frigid cloak
Thanks. I'll probably take a look at how the CI does it tomorrow

discord newbie question, prompted by stumbling across https://github.com/adafruit/circuitpython/issues/1833 - should the expired discord link just be changed to http://adafru.it/discord?
(if yes, that's pretty much the world's easiest PR, but I don't know how discord invites work so I might be missing something.)

Hello! I'm new to Circuit Python and received my Trinket m0 today. Just went through the beginner guides. I have a project im working on and wanted to know where i can go to ask questions about starting. This the right place?

Hi, @tough scroll ! I'm also new, but I think this is the channel for development on circuitpython itself - if you're looking for help with using circuitpython, I believe that is #help-with-circuitpython. But someone else with more experience can correct me here!

@idle owl @gilded cradle @simple pulsar
after my circuitpython-build-tools mischief, this became an apparent need. gatekeeper WIP. 💂
gilded cradle
Awesome. Thanks for adding the tests @raven canopy.
stuck elbow
@gilded cradle I wonder if you could, when you have some free time and a non-prototype version of pybadge, to help me with testing the games?
because I tested them on my prototype and they work, but someone recently tried them and said they only get black screen
gilded cradle
The badge I have is from the store @stuck elbow, so I don't think it's a prototype
stuck elbow
I suspect it may be some difference between what I have and the final version
gilded cradle
Yeah, perhaps I can give it a try when I get to the sprint in an hour or so
Where are the games?
stuck elbow
https://github.com/python-ugame/jumper-wire <-- this is the platformer
gilded cradle
Oh, the difference may have something to do with the bootloader version. I haven't updated mine yet, but I can check on it a bit later.
Thanks
stuck elbow
and this is the shooter: https://github.com/python-ugame/vacuum-invaders
gilded cradle
Thanks, I'll give it a try a bit later and let you know the results and my bootloader version
gilded cradle
Ok, cool
gilded cradle
@stuck elbow, when I try it, I am getting an error that stage is missing. If I remember correctly, it should be compiled in. It's possible it wasn't in the CP version that came on the PyBadge.
stuck elbow
ah, sorry, on the m4 you can just copy it
gilded cradle
Yeah, it has an m4
stuck elbow
https://github.com/python-ugame/circuitpython-stage/tree/master/pybadge <-- just copy those 2 files
cerulean pawn
hi, on the circuitpython website. the download UF2 button for Papyr board is giving a 404. I am not able to find if something needs to be done as part of adding a board which will generate those files. But https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/electronut_labs_papyr/en_US/ does contain binaries, just not the ../ directory
stuck elbow
@cerulean pawn https://github.com/adafruit/circuitpython-org/issues/155
gilded cradle
Ok, now it's just a blank white screen
stuck elbow
any errors? :(
cerulean pawn
@stuck elbow do you know how/where the build scripts are? I don't see it in adabot repo at least.
stuck elbow
they are in travis configuration somewhere
gilded cradle
Should I test out jumpers next?
stuck elbow
it will be the same
manic glacierBOT
gilded cradle
Ok
cerulean pawn
okay, thanks. looks like this script https://github.com/adafruit/adabot/blob/c399adaea747bcbed8e8b11a714329bbf79f496d/adabot/update_cp_org_libraries.py
cerulean pawn
I'll try to see if something is missing here
gilded cradle
I can try building from the latest source to see if it works, but as it comes, it doesn't.
stuck elbow
that's 4.0.0rc1, right?
@gilded cradle could you try replacing those lines https://github.com/python-ugame/circuitpython-stage/blob/master/pybadge/ugame.py#L24-L33 with display = board.DISPLAY?
gilded cradle
Strangely enough, the boot_out.txt file with what comes on it says 3.0.0-rc1, bus same results with 4.0.0-rc1
Sure, I'll try that
gilded cradle
I'm using the frozen uGame which is already using board.DISPLAY
manic glacierBOT
stuck elbow
huh?
stuck elbow
it works on my prototype, with the link, so that shouldn't be it
also works for µGame
how do you know that the frozen ugame.py is using board.DISPLAY?
gilded cradle
Well, looking at the current circuitpython source shows it is
stuck elbow
can you update the submodules?
gilded cradle
Yeah, let me try recompiling and see if that helps. I just tried downloading RC1
gilded cradle
Ok, interesting results. First, after copying rc1 down, I was able to remove the external stage.py and got the whitescreen instead of the error. Second, after compiling and placing it on the PyBadge, I saw the game for about 1 second and then it went white.
stuck elbow
and still no errors?
gilded cradle
Not on the screen. Let me check the serial output.
manic glacierBOT
gilded cradle
No output on serial
raven canopy
@cerulean pawn the libraries_updater script doesn't update the firmware links. Those are done with tools/build_board_info.py in the core repo.
gilded cradle
You're welcome
stuck elbow
now I need to figure out why it works on mine, but not on yours :(
@meager fog was there a change in the display used on pybadge?
trim elm
I'm having an issue with Travis. I fixed an image link in the Circuit Playground repo, and travis is saying: ../README.rst::image file not readable: docs/_static/circuitplayground_express.jpg
The command "cd docs && sphinx-build -E -W -b html . _build/html" exited with 2.
cerulean pawn
@raven canopy yeah I found that out later. I got to that one because top level Travis config only had this one script mentioned
raven canopy
:+1:
meager fog
@stuck elbow nope, same display
@gilded cradle hihi by chance do you have a link to your pybadge example code
stuck elbow
@meager fog so the only thing that changed was PA01 and PA00 being swapped, right?
meager fog
yes, pygamer also has a differnet pin for DC i think than pybadge
stuck elbow
I can't imagine how it would work on my prototype but not on the final pybadge
stuck elbow
a flash of correct content, and then suddenly white display
the program continues on running, no errors
gilded cradle
As @stuck elbow said. My badge code that I linked to runs fine though.
stuck elbow
I am reinitializing the display, that's probably throwing it off
@gilded cradle you didn't try with display = board.DISPLAY?
gilded cradle
I was able to use the frozen module when I compiled and that was already in there
meager fog
@timber mango do a hard reset
that will always clean u up
and then do a SWRST after
but give yourself maybe 50ms
@gilded cradle thanks, ill be rockin this badge
stuck elbow
I will try that
meager fog
oh kool i will!
gilded cradle
😃
ruby atlas
@gilded cradle Having the buttons work made the badge a lot more fun.
stuck elbow
@gilded cradle would you have some more time to try it with this file? https://github.com/python-ugame/circuitpython-stage/blob/master/pybadge/ugame.py
gilded cradle
Sure
stuck elbow
much appreciated!
gilded cradle
No change even with adding display = board.DISPLAY
stuck elbow
and with the full re-initialization?
stuck elbow
what happens when you just 'import ugame' from the REPL, without running the game?
upbeat plover
you got a reset pin on that display?
gilded cradle
I'll try
stuck elbow
@upbeat plover the init sequence resets it
gilded cradle
white screen
stuck elbow
can you freeze the one I linked?
upbeat plover
@stuck elbow looks like same init sequence as feather m4 minitft but is missing reset pin
gilded cradle
I'll try. Do I need to edit it so that it has display = board.DISPLAY
stuck elbow
no, please use it exactly as it is in the repo right now
gilded cradle
Ok, I'll try that
upbeat plover
after spi unlock reset pin should be done?
stuck elbow
@upbeat plover FourWire does it
gilded cradle
Showed for a second, then white
stuck elbow
and importing it from REPL?
are you sure it's not using the pygame.py you have copied to /lib?
gilded cradle
Let me check
I think you meant ugame.py. I deleted the files from lib and same result. importing ugame from REPL resulted in just a white screen even after releasing displays before importing.
stuck elbow
and without releasing the displays?
gilded cradle
Same
stuck elbow
ok, one more try, please, can you change the boudrate to 12000000 at https://github.com/python-ugame/circuitpython-stage/blob/master/pybadge/ugame.py#L51
gilded cradle
Ok, just a moment
gilded cradle
Yeah, I figured that out when it came back after 1 second the first time.
Anyways, lowering the frequency made it work for 2-3 seconds before going white
gilded cradle
Well, it's only working for about a half sedond before going white now
stuck elbow
when it goes white, is that instant, or can you see it getting filled?
gilded cradle
It shows the game animating for a moment before going white
stuck elbow
but does the white appear on the whole screen instantly, or does it get filled slowly with white?
gilded cradle
instantly
stuck elbow
so it's something with the display
gilded cradle
Perhaps
stuck elbow
the code would need time to fill the screen white
it's not that fast
plus, it works on my prototype :/
which game is it, the vacuum invaders?
after about half a second it makes a sound
gilded cradle
Yeah, I'm not sure what's up with that. I could see if it does the same thing on another pybadge
stuck elbow
can you try jumper wire? it makes no sounds
gilded cradle
No sounds. Jumper wire from what to what?
upbeat plover
game jumper wire example
gilded cradle
Oh, sure I can try it
tulip sleet
jumper makes no sounds for me on pybadge; JP says the MakeCode folks aren't finished with sounds yet.
stuck elbow
@tulip sleet you mean it works for you?
I'm talking about this: https://github.com/python-ugame/jumper-wire
tulip sleet
I was trying the MakeCode Arcade Jumper program (not sure about "wire"), testing the bootloader fixes last night that fixed the A/B button swap problem. But there's no sound: JP says that's expected.
OK, we are talking about different games, sorry
gilded cradle
Same result with Jumper Wire
gilded cradle
@tulip sleet, they just announced in #help-with-makecode that sounds are now working
upbeat plover
would reset pin make screen go white? lol sorry im stuck on reset pin
stuck elbow
yes
tulip sleet
@timber mango did you say you have a proto pybadge? There have been several pin revs, I think.
gilded cradle
I'll try a different pybadge, but I'm not sure.
stuck elbow
@tulip sleet but this is python code, it uses pin names from board, so it should be good
tulip sleet
but if the underlying PA PB pins are different, not OK? I mean electrically they chagned
which pin are you using for sound?
I'll look back at the older rev schematics
gilded cradle
Oh, one other thing I noticed @stuck elbow. After the screen goes white, it remains white (even with working code) until a hard reset is performed.
stuck elbow
the game without sound doesn't work either
upbeat plover
only idea i have is remove reset pin from fourwire, and call reset after spi unlock and see if that helps but that really shouldnt do anything different and if it does then some issue else were?
stuck elbow
@upbeat plover let's try this, if @gilded cradle is still up for it
gilded cradle
I'll give it a try
stuck elbow
ok, newest version: https://github.com/python-ugame/circuitpython-stage/blob/master/pybadge/ugame.py
gilded cradle
Ok, that version worked for like 10 seconds
stuck elbow
progress
gilded cradle
It seems to work somewhere between 2-10 seconds randomly
stuck elbow
battery?
gilded cradle
Plugged in via usb
gilded cradle
Yeah, something like that
upbeat plover
😦
stuck elbow
crosstalk on the rst pin?
gilded cradle
I'm not having problems with normal displayio
stuck elbow
you are not sending a lot of data with it
gilded cradle
But also not much animation is occurring
stuck elbow
right
on a completely unrelated note: https://hackaday.io/project/165450-handheld-feather-wing
@gilded cradle thank you very much for helping me with this, I don't think we will be able to solve it like that
upbeat plover
would switching this line to```python
_reset.switch_to_output(value=0)
```python
_reset = digitalio.Direction.OUTPUT
do anything different?
stuck elbow
the second line does nothing
upbeat plover
it sets to output then the ```python
time.sleep(0.05)
_reset.value = 1
time.sleep(0.05)
be doing the work
upbeat plover
never set to value zero?
gilded cradle
You’re welcome @stuck elbow
stuck elbow
it doesn't set anything to output, it just sets the variable _reset to point to the value digitalio.Direction.OUTPUT
upbeat plover
_reset = digitalio.DigitalInOut(board.TFT_RST)
_reset = digitalio.Direction.OUTPUT
time.sleep(0.05)
_reset.value = 1
time.sleep(0.05)
i thought tft_rst is
stuck elbow
first line sets the reset to DigitalInOut, second discards that and sets it to the other value
it doesn't do anything to that DigitalInOut
it's like:
x = 1
x = 2
_reset = digitalio.DigitalInOut(board.TFT_RST)
_reset.direction = digitalio.Direction.OUTPUT
time.sleep(0.05)
_reset.value = 1
time.sleep(0.05)
o yes this then?
stuck elbow
not sure you can assign to direction
switch_to_output is for that
even if you can, it does the same thing
upbeat plover
that code is from digitalio example
in readthedocs
what is used to set LED pins high and low
@stuck elbow im sorry if im not much help just, im not a pro by any means just have theory your reset pin is doing something on the badge
main meteor
Looks like _reset is pointing to a DigitalInOut object, and is then controlled by assigning things to its members (like "direction" and "value").
tulip sleet
@timber mango what is the rev letter on your board? I think it's between the SPI flash and the I2C connector.
stuck elbow
@tulip sleet can't see anything
tulip sleet
@timber mango, ok you have a very proto one, so maybe some pin changes. we need to get you a current one. limor is offline right now and I don't know the history of the pin changes
stuck elbow
@tulip sleet I don't think this problem is due to pin changes, I have a recent version of CircuitPython working on mine, just had to swap PA00 and PA01
it really looks like crosstalk between TFT_MOSI and TFT_RST or something like that
tulip sleet
when did you receive your board?
stuck elbow
04/11/2019
tulip sleet
there's no headphone jack on current boards, so I'm working backwards
stuck elbow
@tulip sleet I really think this is some kind of crosstalk problem on the rst pin on the new boards, or something similar
I can't imagine anything else giving this random effect
maybe power fluctuations
upbeat plover
the issue is with current boards not your proto board? your proto board screen doesnt go white?
upbeat plover
yeah i think you need new board... lol the dev should have the newest version... just saying
stuck elbow
I'm not a dev
upbeat plover
oh i thought you dev the ugame stuff
stuck elbow
oh, of the ugame stuff sure, but that's not adafruit stuff
I have the latest version of µGame :P
and all 10 prototype versions I made

ruby atlas
@tulip sleet @slender iron Thoughts on naming? https://github.com/rhooper/Adafruit_Circuitpython_Dotstar4
https://github.com/rhooper/Adafruit_CircuitPython_Pypixelbuf
Still working on the neopixel library.
tulip sleet
@ruby atlas Hi! at the copyediting level, use "DotStar" instead of "Dotstar", and "PyPixelBuf" instead of "Pypixelbuf". Is that what you meant, or also the "4"?
ruby atlas
I wanted to start the discussion on the naming. I chose 4 because it's for CircuitPython 4 and up.
@merry turret I'll rename the repos (and copyediting).
OK Those two renamed, now to check for copy-editing errors.
tulip sleet
@ruby atlas I didn't mean literally copy-editing except for the repo names.
ruby atlas
There's some capitalization errors in the contents too 😃
tulip sleet
Also, I was looking at arduino neopixel this morning, and I saw how it encoded what's in your tiny classes just as an integer: https://github.com/adafruit/Adafruit_NeoPixel/blob/master/Adafruit_NeoPixel.h#L73
halcyon breach
The circuitpython express is too much fun!
tulip sleet
it would certianly be unpythonic to do this in general, but I did the same thing (bit-encoding) in the HID library a long time ago, and it saved a LOT of space
ruby atlas
I tried to be pythonic with the classes so we could differentiate between RGB, RGBW and RGB(L=brightness) in the implementations.
I agree it uses a fair bit of space. I tried going through and removing classes, but got super nervous about removing some.
The other possibility is to have a single class and initialize them at load.
tulip sleet
i think having an integer const for each would be fine, and you could extract the necessary info by bit operations
they're basically opaque names to the end user
i'd think
so their representation doesn't matter to the end user
knotty cypress
Working on Netpbm images, have working mono and greyscale
ruby atlas
@merry turret I made properties on the byte-order classes so you can retrieve the BPP and/or white and/or luminance settings. I guess we're not losing too much if I go and remove that to save space.
trim elm
Quick question. I was restoring the firmware on my feather M0 because it wouldn't let me write and gave me a read-only filesystem error. Now it only mounts FEATHERBOOT. Does this mean it's dead?
tulip sleet
you could have a single class that stores an integer and properties to extract those values from the integer. The constants would be instances of a single class instead of singletons
ruby atlas
@tulip sleet Yep, I think that makes sense.
I hope I can find time to do that before my free time vanishes.
tulip sleet
@ruby atlas we have to find another conference for you to go to.
ruby atlas
Preferably people will also respect my requests for minimal meetings too.
tulip sleet
@trim elm what .uf2 did you copy to the Feather M0?
trim elm
update-bootloader-feather_m0_express-v3.3.0-adafruit.10.uf2
tulip sleet
that's the bootloader itself, not the CircuitPython firmware. Go to https://circuitpython.org and download the latest version of CircuitPython for the board, and drag that to the BOOT drive.
trim elm
Ah, that makes sense. Thanks!
tulip sleet
once you've done that, connect via the REPL and do:
import storage
storage.erase_filesystem()
that will reformat CIRCUITPY (and erase it)
trim elm
Ok
slender iron
@ruby atlas I don't understand what naming. Can't we just release a new version of the existing library?
ruby atlas
We could, but then we have to deal with non-express boards needing new instructions (eg: install pypixelbuf).
ruby atlas
That seems like a lot of broken guides and tutorials and educational content.
slender iron
then let's fix them
these are all onetime costs versus having two libraries in the long term
we can make sure the error message is good too
ruby atlas
The underlying import is still the same with pixelbuf compatible libraries. How do we make sure we can do the migration gradually and painlessly? While the hard cutover is cleaner in one way, I worry about the amount of pain and extra work doing it so will cause. For the boards that freeze NeoPixel or Dotstar it will still work as expected.
trim elm
Is there a way to be able to read and write to the filesystem? I'm able to boot it in read mode and boot it in write mode, but I can't figure out how to do it simultaneously.
trim elm
Ok. Thanks. I think I'll just hook up a switch for grounding the pin to switch the read/write mode.
slender iron

I am interested in porting CircuitPython to a 32-bit NIOS II micro on an Intel MAX 10 FPGA. Are there any instructions for a ground-up build like that?
I have done some digging around, and most of what I can find still presumes that the final target is a SAMD of some kind.
It looks like MicroPython was ported to the Zephyr RTOS which can run on a NIOS II. And there appears to be a fork of that port for CircuitPython, also. So, that's a possible path, but a native build for the NIOS seems like it would be more optimized in the end.
I also assume the first hurdle is getting the UF2 bootloader running on it. Lady Ada's UF2 video from about 2 years ago seemed to suggest that UF2 could only be used with SAMD devices. Is that still the case?
A lot to learn, here.
Any thoughts? Thanks!
tulip sleet
@old smelt There is also an nRF52 UF2 bootloader.
The hard part in most ports is supporting the chip-specific periperhals (I2C, USB, etc.). Does this FPGA impl include a USB peripheral? That's kind of central to CircuitPython's workflow (CIRCUITPY).
Our fork includes port/* inherited from MicroPython, but that does not mean we support most of those boards: we have just not removed them from our fork, so that merging from upstream is easier.
We have talked some about a Zephyr port, but that's a significant amount of work too. If Zephyr already support the NIOS II peripherals well, that might be attractive.
old smelt
Thanks @tulip sleet. Yes, the Particle boards are nRF52 based, correct? And they support CP, so that makes sense.
I believe we could clear the USB hurdle, as well.
Thanks for the clarification on the ports. That makes sense with what I see in the repo.
old smelt
Our hardware is FPGA-centric, but I am fascinated with CircuitPython and would love to find a way to get it running on one of our boards. I think it could open the doors for some cool CircuitPython + FPGA integrations.
tulip sleet
@old smelt the architecture is not ARM, right? What version of gcc are you using? We're on 7.3.1 and will move up to 8 soon.
old smelt
That's correct, it is not an ARM core.
tulip sleet
what size of RAM and flash are available?
old smelt
Don't have that at my fingertips. Hold on...
raven canopy
I'd look at FuPy and TinyFPGA. They've put uPy on FPGAs...
https://nick.zoic.org/art/fupy-micropython-for-fpga/
old smelt
Thanks @raven canopy . I was just looking at that earlier today, as well.
I will revisit that project, as well.
old smelt
@tulip sleet - looks like the M50 has ~204KB RAM and 736KB Flash. The flash includes storage for the FPGA image, and I'm not sure how much of the FLASH that uses up. When we first started talking about this, I thought that if we targeted a config similar to the M0 Express (256KB flash + 32KB RAM), that would be a great starting point.
Lots of tradeoffs to consider...
tulip sleet
that's quite good, assuming say 256-400k flash is available. Depends on the machine code density for this architecture. The SAMD51J19's we use are 192kB of RAM. 32kB of RAM is pretty minimal: we only end up with a 20kB heap or so, so even 64kB is a lot better.
old smelt
Ok. Thanks. I'm pushing internally to see what we can make happen. I think it could be very interesting.
My long-term utopian target is Python as a design entry language for high-level synthesis. Projects like FuPy and MyHDL are moving things in the right direction, and I see the rise of MicroPython and CircuitPython as key technologies that clearly enable and promote Python on small hardware platforms.
There's a lot of work to do to make that happen. But it's fun to think about.

@solar whale are you around the next few days? I think I have a fix for internal flash nrf
solar whale
@slender iron yes. I’ll be happy to test it.
slender iron

solar whale
Woohoo! pr_1870 works on the pca10059
slender iron
great!

will test the others in a few minutes
slender iron
thanks, I have a feeling it's the same issue
it was trying to write out the cache when it had to content (and therefore address 0xffffffff)
solar whale
yup - works fine on the makerdiary_nrf52840_mdk_usb_dongle
Thanks for the quick fix!
slender iron
np, trying to get everything in for an rc.2 that we can call stable next week
solar whale
OK an all three -- sparkfun_nrf52840_mini works!
slender iron
thanks!
solar whale
now just verifying it is OK on the express boards 😉
all good - feather_nrf52840_express OK -- I'll try to run more tests on the boards onver the next few days.

i'm trying to freeze my tg_gui into the firmware. i cloned my repo into $(TOP)/frozen/tg_gui i added :FROZEN_MPY_DIRS += $(TOP)/frozen/tg_gui/system.py FROZEN_MPY_DIRS += $(TOP)/frozen/Adafruit_CircuitPython_CircuitPlaygroun
to the mpconfigboard.mk file. i get this error: FREEZE ../../frozen/tg_gui ../../frozen/Adafruit_CircuitPython_CircuitPlayground ../../frozen/Adafruit_CircuitPython_HID fatal: No names found, cannot describe anything. fatal: No names found, cannot describe anything. Traceback (most recent call last): File "../../tools/preprocess_frozen_modules.py", line 14, in version_string tag = subprocess.check_output('git describe --tags --exact-match', shell=True, cwd=path) File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 395, in check_output **kwargs).stdout File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/subprocess.py", line 487, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command 'git describe --tags --exact-match' returned non-zero exit status 128.
but without the tg_gui folder added to the libraries to freeze it compiles and i can import adafruit_circuitplayground on an itsybitsy m4
raven canopy
@marble hornet "cloned my repo", how? git clone or git submodule add?
marble hornet
git submodule add
exotic pumice
does it need to be tagged?
raven canopy
did you run update afterwards?
i think you still need to run git submodule update --init --recursive after adding.
marble hornet
how does FREEZE know how to look for the specific py files inside of Adafruit_CircuitPython_CircuitPlayground. since the files to compile are inside of a folder inside of Adafruit_CircuitPython_CircuitPlayground?
hrmm...
i can freeze each module individually by hand
tulip sleet
@marble hornet See these files:
$ ag PREPROCESS_FROZEN
mkrules.mk
125: $(Q)$(PREPROCESS_FROZEN_MODULES) -o $@ $(FROZEN_MPY_DIRS)
mkenv.mk
76:PREPROCESS_FROZEN_MODULES = PYTHONPATH=$(TOP)/tools/python-semver $(TOP)/tools/preprocess_frozen_modules.py
on it
tulip sleet
@marble hornet if you just make your files/directories look like the frozen modules, you'll be OK. You need to tag the submodules so it can put in version info.
tulip sleet
no, a git tag, a version number
marble hornet
ah, okay
exotic pumice
called it an hour ago (sorry if I'm being annoying, I had too much coffee)
tulip sleet
do you just have some random files you want to freeze? I think you can also still use FROZEN_MPY_DIR (not FROZEN_MPY_DIRS), and point it at a directory (don't use frozen)
that does not get preprocessed, if I remember right
pastel panther
hey @trim elm did we meet at PyCon?
trim elm

Sorry but I met a lot of people. Which of them were you?

pastel panther
hey!

trim elm
@exotic pumice Cool. No clue what that is, but it sounds interesting.
exotic pumice
I made a more user-friendly interface for ADCs in Rust. Think like arduino's analogRead()
@trim elm What are you working on with ADCs?

Cool. I was changing the circuitpython library for a 12 bit ADC to output an 16 bit value

trim elm
@exotic pumice I was sprinting with them at pycon and that was an issue I decided to try and solve. I think that the purpose was just for consistency
tulip sleet
it's possible the singular DIR doesn't work any more
exotic pumice
@trim elm ok cool
marble hornet
i tried w/ and w/out s
tidal kiln
yah, 16 bit, CP has standardized on that:
https://circuitpython.readthedocs.io/en/3.x/shared-bindings/analogio/AnalogIn.html#analogio.AnalogIn.value
exotic pumice
interesting
trim elm
Oh, yeah. I meant 16 bit not 18 bit
tidal kiln
for AnalogIn.value anyway
exotic pumice
I was surprised it looked like arduino was only using 10 bits (https://github.com/adafruit/ArduinoCore-samd/blob/d331767eacafd121d43668b0b13b210be876c236/cores/arduino/wiring.c#L125)
but there is a 12 bit section of code in another file
trim elm
Does anyone know if I can write to an external adalogger from a feather M4 if the feather's filesystem is in read-only mode
tidal kiln
should be able to. in that case you're writing to the SD card on the adalogger
which is separate from the CP filesystem
marble hornet
@tulip sleet and @exotic pumice thank you, i'v got them all compiling and builtin. but they are all next to eachother in freeze. working on keeping them all in tg_Gui
exotic pumice
cheers
tulip sleet
you tag a commit
raven canopy
hmm. i thought the submodule commit tag would work, but 👏 @exotic pumice!
trim elm
@tidal kiln Ok. Thanks. I'll try that tomorrow. Hopefully it works since it's a pain to have to reboot it every time I want to change any code.
tulip sleet
right. our submodules are tagged in their own repos and when they are brought in, the tags come with the commits. You could tag your libraries in their own repos and update them in your cpy build tree as necessary
marble hornet
do i tag then commit or commit then tag?
raven canopy
tag a commit. for instance, CP libraries are tagged at the last commit upon release. (i've never git tagged outside of a release in GitHub...don't assume i'm smart on the subject. 😄)
tulip sleet
@marble hornet you can tag and then push the commit. You can do git push --tags to make sure it goes up to github
marble hornet
will do
thank you @tulip sleet and @raven canopy and @exotic pumice ! it's (almost) working! i just need to do some reorganization
exotic pumice
lol it costs $11 to ship a 7g blinka pin 😦
🇨🇦
maybe I'll try to get it ordered from bc-robotics
y'all gotta give them some love though, they don't even have any M4s I don't think
when pygamer comes out can I get one through a distributor or is it adafruit-only?
tulip sleet
@exotic pumice Ask your distributor. I don't know how things are allocated to distributors. Quantities are limited when something first comes out. Some distributors only stock a limited selection. The larger distributors like DIgi-Key and Mouser have a wider selection.
exotic pumice
yeah, just wondering if there's some kind of rule that you only sell direct to consumer for the first few batches, or otherwise
I'll keep my eyes peeled for the notice of them going in stock and see if I can get my distributor to order them
can someone tell me if I'm doing something obviously stupid here?
https://github.com/sajattack/ili9341-rs/commit/579a497b72945c38813caf98a478f9154592b371
oh hold up
is dc supposed to be high for commands?
main meteor
What am I looking at here? Looks like a weird dialect of VHDL.
main meteor
Yeah, the unrolled bitwise copy seemed oddly verbose.
tulip sleet
i don't know the answer to your DC question, but could you combine data0-data7 into a single byte which you write in parallel? Otherwise it defeats the purpose of parallel write
exotic pumice
not easily
I timed it and it's still only like 20ms update
which is like 50fps
I think I have an issue with dc though
oh nevermind, I see what it's doing now
tulip sleet
the lower level CMSIS-style API could take data in parallel. Take a look at the C code we use
the CPU time spent doing this could be doing other things
stuck elbow
@exotic pumice just look at how https://github.com/adafruit/Adafruit_CircuitPython_RGB_Display does it
ah, sorry, unless you use the parallel interface
exotic pumice
yeah, I'll get to optimizing it, but first I need something to work
main meteor
I know that feel.
tulip sleet
understand - yes
exotic pumice
the problem with using the lower level interface is it's not portable
rust drivers generally try to be portable across the ecosystem
tulip sleet
but could the upper-level driver provide a parallel write which would be implemented in different ways per port?
exotic pumice
yeah, I kind of want embedded-hal to make up a port interface
like, right now we just have pin-level reads and writes for the hal
as portability abstractions
tulip sleet
in our case, displayio takes a starting pin and assumes the rest are consecutive, so it can do them in parallel
agree, though, get it to work first. we have a lot more optimization to do too
tulip sleet
yes, displayio takes that directly, so itself is the hal and short-circuits any intermediate layers
exotic pumice
this is what I'm working with for portability reasons https://docs.rs/embedded-hal/0.2.2/embedded_hal/digital/trait.OutputPin.html
tulip sleet
exotic pumice
every hal author uses these common sets of traits, and then drivers build on top
tulip sleet
in our case, the use of the consecutive pin is implied by the starting pin
exotic pumice
yeah I don't think I can do that
tulip sleet
we could also take multiple pins in the constructor, and then check that they satisfy a constraint for that particular port (e.g. consecutive, on a pin number byte boundary, etc.)
i think it's worth discussing with the API authors, because parallel data is a needed thing
exotic pumice
yeah I'm working on it lol
generally the common api is a great strength, but there are gaps
slender iron
@exotic pumice we do usually restrict first batches to adafruit.com only so that we can do customer support directly if anything comes up. after the first few we're pretty confident that the kinks have been worked out
exotic pumice
ok good to know, thanks @slender iron
upbeat plover
i got my CPX back from a friend last night, tested play_melody(), worked well. I notected there is an open issue with CPX for sine waves playing not very loud. Can add optional parameter to _sine_sample() for slight volume control, normal no parameter change, or louder or quiter setting. adding it to that would also need the option placed in play_tone() start_tone() and play_melody(). but for play_file() you would need to control volume within the .wav file
meager fog
@gilded cradle p0ng if yr back
meager fog
you wnana write up a guide for pybadge to use your code?
i thought it would be cool to show how to use different languages
so you could have it say "Hello my name is: <name>" but in a variety of languages, since we have unicode
gilded cradle
Yeah, definitely. I was thinking about asking you about doing that.
meager fog
you'd have to find fonts that have all unicodes in em, but im sure they exist out there 😃
kool!
assign yrself 😃
it would really show off the power of python since arduino cannot do multilang
meager fog
yep plz add so you have it tracked
gilded cradle
Will do
exotic pumice
@slender iron aside from being ugly as sin and inefficient, do you see anything wrong with my parallel driver? https://github.com/sajattack/ili9341-rs/commit/579a497b72945c38813caf98a478f9154592b371
I could use another pair of eyes
is there any initialization that changes between 8bit and spi?
I read it was set by pins on the display
meager fog
heya saj, the init sequence is the same, but this isn't gonna be a good place to get rust support - i dont think anyone here knows rust :/
they may have their own discord servers with rustxperts? 😄
exotic pumice
yeah fair enough, my bad. just thought you guys know the displays
and the code is like, set this pin high, set this pin low
meager fog
we have code you can look over - but no rust experience - check the code for arduino and/or circuitpyt. good luck! 😃
exotic pumice
thanks
a display question then? is it fine to leave cs low the entire time?
or better to have it only when writing
meager fog
i dont know off hand - whateevr we do in our arduino/cicuitpython lib is what you can follow. can also read the DS, they'll have a timing diagram
gilded cradle
It depends on the display. For instance the ST7789 requires a CS toggle between each command.
celest zenith
github process question. If I found a bug and have a fix for https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI would you like me to create and issue and a PR that fixes it or just the PR
meager fog
just a PR is fine 😃
exotic pumice
ok thanks @gilded cradle, I'll try changing that section of my code
gilded cradle
Cool
meager fog
thanks melissa, you def know your displays better than me now
meager fog
@exotic pumice you can also try putting the pyportal display into SPI mode with the back solder jumper/s
exotic pumice
it's not my pyportal, the person who has it was hesitant to do that
meager fog
ooh ok
im sure y'all will get it working!
one thing to use for testing is the invert command, once its inited
its a simple one byte command so good for testing
exotic pumice
thanks, yeah I can't even get it initialized
tulip sleet
@gilded cradle I think @upbeat plover might have such a universal font
gilded cradle
Oh right @tulip sleet, from working on the Chinese Translation.
upbeat plover
https://github.com/hexthat/circuitpython/blob/patch-1/tools/fonts/ter-u12n.bdf this is the font i made, think @slender iron changed the cp font to be better like the one i made?
gilded cradle
I think my badge used 3 different fonts, though I could bring it down to 2 if needed, so I gotta look into what works best.
upbeat plover
for displays you really need fonts, for like serial/REPL you can use unicode but it wont show up on displays without the unicode for the glyph in the font
gilded cradle
Yeah, it's for the displays. I think she was saying to use fonts that have all the glyphs so we can support many languages.
upbeat plover
@gilded cradle if you find a font you like missing some accents i might beable to add them for you.
gilded cradle
Awesome, thanks @upbeat plover
meager fog
yah - like i think arial is a 'complete' font
they're like 1mb but they have everything
gilded cradle
Yeah, I used Arial, Verdana, and Comic
upbeat plover
i like bold arial, nice font there

@tulip sleet I have two PRs out to you. they are the last we need for a new rc I think
tulip sleet
yes, I'm working on some bootloader stuff for PyBadgeLC. Still need to test yours. Can you wait until tonight? I have to

slender iron
ya, waiting is fine. just want it out by end of tomorrow

So I think I might have found another issue with travis
It keeps failing and it says:

The command "cd docs && sphinx-build -E -W -b html . _build/html" exited with 2.
I've verified that the image is readable

My guess is that it needs to be "./static/" to make it relative
trim elm
Ok. I'll try that
upbeat plover
travis is working now for the cpx PR "volume and melody", travis must have just been busy?
slender iron
ya, library builds can get stuck behind the circuitpython build

@slender iron w.r.t. BNO055 review - just wearing multiple hats. was basically just trying to get them green in travis, after that I tagged it for review by CP Librarians. which is where it's currently sitting.

I saw that. I'm not sure what is left though for review
tidal kiln
you're probably right. i can put on my CP Lib hat and go check again and merge etc.

@upbeat plover got a moment to discuss your 2 CPX PRs?
raven canopy
k. I hadn't merged #52 yet; got side-tracked. but now #57 has the same updates as #52, but they also differ slightly (volume in play_melody, removing the length kwarg in _generate_sample()).
upbeat plover
would it be better if i didnt merge volume with melody? like have PR for melody and PR for volume seperate?
raven canopy
yeah, i would say so. will require some git-fu for #57 (just a git pull to merge in upstream merges).
lets work #52 real quick.
upbeat plover
@raven canopy not sure how i did that or why.... dargh
i think i added the param back
raven canopy
hehe. all good. i have way more mistakes then non-mistakes. 😄
@upbeat plover i would just git revert those last two commits for #52. then if you still want to change all of that up in #57, you can. I am not sure that the math will work out for frequencies >3500, and I have to run out for the evening.
upbeat plover
im not sure how you do that i only use web browser github
raven canopy
hmm. yeah, i'm not sure you can revert on github...
upbeat plover
yeah... it kind of embarrassing people can 100% see how i do stuff lol.... and all the mistakes i make, but im like hey w/e true open source right?

Hello, I am curious if there might be anyone working on cap touch for the M4?
I see last comment was from March
I have a friend that would love to use cap touch with the M4 boards but looks like there still a lot of work to do?
lone sandalBOT
tulip sleet
@fierce girder We have a cap touch implementation that @crude fossil did for nrf that is not port-specific. It requires a 1 Meg resistor and just GPIO: https://github.com/adafruit/circuitpython/pull/1499. We have an issue to make this available across all ports: https://github.com/adafruit/circuitpython/issues/1517.
It would also still be possible for someone to reverse engineer QTouch, but @slender iron spent a lot of time on this: it seemed quite different than SAMD21.

and then we'll sweep thru the repos to see any still using the older spi commands and if none, we'll protect em
gilded cradle
I think I already did the hx8357
meager fog
oh yah?
gilded cradle
That’s the one we don’t do
See how the others funcs have sendCommand
Did we want to add readCommand into GFX?
meager fog
umm yeah please do
i was just thinking but yes we do use it for ILI9341 to identify connection
so we should just do em
gilded cradle
Ok, Cool. I'll do that next then
gilded cradle
@meager fog, it looks like the readcommand8 functions are different between the HX8357 and ILI9341. It appears the ILI9341 is a little more "specialized".
meager fog
they are somewhate specialized, but maybe there's some way we can generalize? :/

raven canopy
well, once i get the build-tools to recurse subfolders merged (again, without breaking stuff), you could point to the release bundles. not sure how to do it in an easy future-proof way though.
tidal kiln
that'd be a zip of the whole bundle?
raven canopy
yeah, but just the examples. currently, that particular one only contains a single example file.
tidal kiln
ah. i see. it's not the whole bundle - just for that repo
raven canopy
yeah. circuitpython-build-tools runs for both the whole bundle and each individual library.
tidal kiln
that could work. could future proof by giving this as link:
https://github.com/adafruit/Adafruit_CircuitPython_BNO055/releases/latest
and then just say something like "download the zip with examples in the name"
raven canopy
yep. i wonder if there's a way to do it with PyPI/setuptools. i doubt it...but i'll look.
tidal kiln
i know that's been a general limitation before
but thanks for the examples.zip idea. i think i'll go with that. that's a little more familiar than git clone.
and also realizing need to do a version bump on that repo
raven canopy
there's quite a few that could use it. i was planning on hitting some of the list a little this weekend.

Will do some more checking before filing an issue

@solar whale This is almost certainly due to https://github.com/adafruit/circuitpython/pull/1860
solar whale
@tulip sleet thanks. I guess the sd card lib needs some work to be compatible.
I’ll try to look at it tomorrow and at least file an issue. I’ll be gone for two weeks on Monday...
tulip sleet
I see the issue in the libary, or at least the first issue 😃
solar whale
😉
tulip sleet
buf[0] = 0x40 | cmd
buf[1] = arg >> 24
buf[2] = arg >> 16
buf[3] = arg >> 8
buf[4] = arg
buf[5] = crc
these need to be narrowed to 8 bits
solar whale
Just needs a few &0xff
tulip sleet
I'll submit an SD card lib issue.
solar whale
Thanks! Glad it’s a simple fix...
solar whale
I hope to have time tomorrow to try it.
solar whale
We’ll see how many PyPortal examples are broken by it 😉

cpx PR #57i feel that is needed, but i removed melody from it. no way to control volume in tones without something changed
@raven canopy
also, melody not in frozen alows you to put code in the loop, if you need stuff to update while song playing

@slender iron I have a (very) rough first draft of converting shared-binding docs to .pyi stubs, just a few questions before I make a PR to add it to circuitpython:
1: what workflow should it be part of, eg, make stubs or something else?
2: where should the resulting stubs be located?
3: should I only include the contents of shared-bindings, or are there any other directories worth including?
slender iron
@somber coral epic! Make stubs sounds good. 2) build somewhere? Up to you. 3) just shared bindings. Give us incentive to move stuff over. Will need to sort out cpu thin conflicts like time
somber coral
ok, I'll try to see if there are standard directories that vscode/et al look for, or if there should be some sort of central config to set
somber coral
also, I noticed some cases where the docs either don't use PEP484 compatible syntax, or otherwise have some hokey data that won't generate correct stubs
I keep forgetting we can declare stubs via PyPI packages now
btw, if you want to see what it currently generates, pip install rst2pyi then run rst2pyi shared-bindings stubs from circuit python root
slender iron
Ok awesome. I figured that we’d need to clean up some of the docs
We can rally folks to fix them if we have a list of what is broken
somber coral
the current logic for generating imports for the stubs doesn't yet support nested types yet (eg, Union[foo, bar]), but it's on my list
slender iron
Kk. I’m excited to see this! Thank you!
somber coral
happy to hav something substantial to dig into 😛

I'm seeing the same rc2 SD-related OverflowError on PyPortal. Also getting similar OverFlow error with rc2 on ItsyBitsy-Airlift combo when using ESP32SPI set_digital_write: File "adafruit_esp32spi/adafruit_esp32spi.py", line 653, in set_digital_write File "adafruit_esp32spi/adafruit_esp32spi.py", line 307, in _send_command_get_response File "adafruit_esp32spi/adafruit_esp32spi.py", line 219, in _send_command OverflowError: value would overflow a 1 byte buffer
meager fog
@crimson ferry oi - do you want to try to fix with a PR? you've got it in front of you 😃
crimson ferry
Let me look at the ESP library and the history here of what's happening and see if I can make sense of it.
meager fog
you probably just need to &0xff whatever it is
we historically have been loose with it because it would auto-crop
celest zenith
I can work on a PR for that en ESP32SPI
crimson ferry
@celest zenith I'll defer to you, I don't have much time until Sunday. Plus, you know what you'e doing 😉
celest zenith
Hmm. Looks like it doesn't like assigning a bool to a byte
python cast turns bool in to 0/1
@crimson ferry can you paste your call to set_digital_write
crimson ferry
Sure, this: # 0x0=INPUT, 0x1=OUTPUT, 0x2=INPUT_PULLUP esp.set_pin_mode(pin, 0x1) esp.set_digital_write(pin, val) is called with a numeric pin number and True or False. Should I use 0/1 int?
celest zenith
It looks like the new overflow check does not allow bool to be assigned to a byte.
crimson ferry
Better to make the API to send an int (0 or 1), or change the lib?
celest zenith
int(True) returns 1
and cpython allows you to assign a boolean to a bytearray.
an easy fix in the library is to convert the booleans to int explicitly
meager fog
@celest zenith are we no longer compatible with CPython?
>>> print(a)
bytearray(b'\x00\x00\x00')
>>> a[0] = True
>>> print(a)
bytearray(b'\x01\x00\x00')
should be valid Py3
does it not work?
celest zenith
that does not appear to work in RC2
meager fog
ok ill open an issue
celest zenith
h samd51j19
>>> a = bytearray(3)
>>> print(a)

celest zenith
yeah
BTW, I'm cpforbes on github -- I submitted the PR that added set_digital_write.
I thought I had a bug in there 😃
celest zenith
indeed
meager fog
z0nk
crimson ferry
Just to confirm... rc2 works fine with ESP32SPI esp.set_digital_write if I feed it an int val, 0 or 1, so no hidden issues arose (tested on PyPortal, Feather M4, and ItsyBitsy M4).
celest zenith
I was just about to suggest that that would probably work.
solar whale
SD Card issue for RC2 was a simple fix -- PR submitted - https://github.com/adafruit/Adafruit_CircuitPython_SD/pull/18
stuck elbow
in regular python, bool inherits from int, and True is equivalent to 1

@gilded cradle you hitting the "needs release" list? i was going to grab some over the weekend, so let me know which ones i can get so we don't work the same ones.
gilded cradle
I think I've already released all the ones I planned on, so you should be good to go.
raven canopy
ahh. okie dokie.
gilded cradle
Most of them were example file updates by dherrada that I merged in.
Where is this "needs release" list?
raven canopy
k. i was watching Travis, and saw all the builds but couldn't find any PRs matching the time, so i figured it was releases. 😄
the "old" one is on cpy.org/libraries/contributing.
old = last monday, iirc
gilded cradle
I mean is there a current one?
raven canopy
nope. and since we dropped it from the daily report on adabot, need to run a fresh one.
gilded cradle
Ah, ok.
gilded cradle
lol
meager fog
i can rerun some of the arduino travis
gilded cradle
Yeah, it looks like something happened to the esp8266

oh crikiey
yes

raven canopy
hate it when garbage gets into my JSON. 😜

meager fog
@gilded cradle ok so next up for the displays - we did all the SPITFT's to use sendCommand right?
gilded cradle
Yes
We could potentially move setAddrWindow into GFX with some parameters depending on the specific display needs.
