There use to be one UF2 per commit and I only see one per release... maybe there is some cleaning and only the last artifact are maintained?

Here's a link for the Adafruit S3 bucket https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/ If you're into circuit python you should bookmark it, just a matter of time before you'll want to check out some of the latest builds.

is there a way to force pycharm not to cache?
oh didn't know the device was in read only somehow. i didn't even know that was possible.
only thing i know of that does that is going from 7.3 to 8.0 beta will wipe the pico.
due to repartitioning, which is a huge deal if you don't see it coming and don't make a backup of your running code first.
today is freaky friday spooktacular in Tim's PC. all manner of weirdness going on.
nova totem
That's why I'm thinking it is a memory error that is causing the hard fault. Something with allocating/freeing the memory improperly. Blaming my own poor skills 🙂
sand lotus
Reason I hate hard faults is it never tells you why it crashed. I don’t have a debugger so if I keep running into it usually I’ll try to switch boards if possible. I have a lot of boards to choose from and that’s basically because of hard faults… I’ve learned having a variety of boards to swap between is helpful.
I didn’t say it was a rational hate. I know if it crashes it can’t say why… chicken and egg problem.
frosty dust
He's super close I can feel it in the force
sand lotus
First time I ran into a hard fault I thought it was my fault. Doing too much, taking up too much ram, etc… I spent days trying to work around it before reporting it and eventually saw others were having the same issue. Love GitHub.
nova totem
If it is from me about IS31 it's probably where i broke it
sand lotus
Things break, things get fixed, things break again, the work never stops.
nova totem
I'll almost guarantee it is that PR. I have a hunch on what broke
sand lotus
I love the environment Adafruit has in GitHub and development. There’s no toxic blame like I’ve seen in other places. It’s just super nice and open, very inviting. Love it.
frosty dust
I learned all my kung fu and even how to solder from Adafruit. Everything I was afraid to ask lol.
nova totem
The PR was to make the code work on more generic displays (like the 13x9 matrix) but I do not think I used scaling for that display.
I'm guessing the height passed is 15 when it should be 5 ( divide by 3 for the scaling)
if it is 15 instead of 5 it is probably writing who knows what to memory all over the place
FrameBuffer calls the code you're looking at
Oh yeah it's passing in 15...
FrameBuffer.c line 175.
It should be passing in 15 (cause scaling is on so divides it by 3)
It was hardcoded on 7.3.3
yes
switching to twitch so i have less lag to hearing what you're doing 🙂
sand lotus
What if it can’t divide by 3 evenly like 11
nova totem
Yeah but in the low level code it should be 5 cause the physical display is 5
sand lotus
Write down somewhere the dates of what you have tested...
Good call 👍
nova totem
should be self->scale_height if self->scale is true
chat blocked what you changed, but assuming you set it to 5
height otherwise
actually may not need the if cause in framebuffer constructor it sets to scale_height to height if its not enabled
nova totem
What if it can’t divide by 3 evenly like 11
The scaling function (to make things look better on small displays) is based on 3x3 squares and if you set it not divisible by 3 it tosses an error at construction
sand lotus
So what he’s adding is redundant, that’s good to know.
Doesn’t that bring up the question why didn’t it work then?
nova totem
Ooo also shows up on line 196 too i think
So quick background: scale was from the arduino version where it would create a 3x size display in memory and average squares to make it look nicer on the tiny display
scale_height should always work but let me look too many code windows open
sand lotus
Is that why Arduino text always looks so blocky when scaled up?
Oh derp yeah you’re in the matrix sorry.
nova totem
175/196 could both be:
common_hal_is31fl3741_draw_pixel(self->is31fl3741, x, y, color, self->mapping, self->scale_height);
But yeah 196 isn't scaled automatically so really wouldn't matter
No problem! Worked out that I was on and saw what you were working on
I'm reading the display core to figure out how to get gifs going so needed a distraction

this is some kind of x,y validation issue?

It's odd to see line numbers printed on paper. Printed code in magazines was kinda like the first github sharing before the internet existed. You'd get the magazine and then have to transcribe it into your PC verbatim.
I have about 20 microcontrollers running circuit python and I've never once bricked one... and I'm pretty good at breaking things.
You'd probably have to be messing with boot.py to brick it. I wouldn't even know how to go about intentionally bricking one either.

I have a question. Using also an Adafruit Feather ESP32-S2 with TFT I ported a script to receive UDP multicast packets. Also using CPY with displayio. All works OK except at the line of this command: 'size = self.my_DataRef_sock.recv_into(packet). Here the script is stuck. I arranged port triggering on the router of the ISP. I created rules for UDP in/out in the MS Windows 11 Defender firewall . Before this script was running fine on a Raspberry Pi. Because of some limitations in CPY I could not set certain socket options because they don't exist in CPY socketpool module. With the Wireshark app on the desktop PC I see that the X-Plane 12 flight simulator is broadcasting BECN and DATA packets to the group '239.255.1.1', port 49707, which I programmed into the script.

Unless you're intimately familiar with UDP and circuit python it's not exactly something someone could answer off the top of their head, would require some research so a github issue seems more likely to get the right eyes on the issue.

Yes, I agree that MSFS2020 is in many ways better. However X-Plane has its nice things too. With broadcasting you can use flight parameters for external hardware. For me it was more a way to learn to create programs for this hobby application.

But it’s not converting it to the absolute value

So my week sucks. Found out all the TR-Cowbells might have flawed chips. Have you noticed any issue with switch 8 or 16? I wouldn’t even know how to look for a hardware flaw like that.
Live but not live, Schrodinger’s stream.
The stream in twitch froze up completely but YouTube ok. Had to reset twitch.
From what I read about the issue it’ll exhibit as a failed read, like if press the switch it’ll fail to read. I don’t think it’ll lock up though so maybe not the worst issue in the world. Originally I thought it would cause lock ups on the chip.
jovial estuary
i think it's "all other bits on that port incorrectly read as 1"

Well that means the other 7 will fail? Yeah I’ve never seen that.
I’m really excited to see gamblors progress with animated gifs. With M7’s on the horizon I’m hopeful for something around 15 fps. Most I can get is like 3 fps but that’s more of a spi bus limitation I think.
Yes I was doing full screen on the featherwing tft. I went full bore on as big as I could.
I was trying to do sprite animations as animated gifs. A library just for animated gifs would be awesome. I’ll definitely put it through its paces.
Was trying to do a full screen animated cloud background for weather.
3 fps yeah. I’m also interested in what PIO can help.
Clouds don’t have a ton of color naturally. 😄
The refresh rate yeah, clock. Displays are kinda locked to 33.3 fps but I have overclocked it to around 60.
The HX and ILI displays are more capable than the spi bus itself. PIO is a different angle I haven’t tried yet.
They’ve done a lot of work to http server lately. 👍 Dan was very happy to see others take it and run with it.

Some API tokens will time out after 30 days now but if you use it within 30 days it'll renew.
This is to cut down on the amount of zombie keys available.
They should allow you to refresh a key if you have 2FA enabled. It'll force developers to want to enable 2FA and allows you to refresh a token manually behind a secure login.
Yeah Dan was pretty stoked to have someone to talk about asyncio developement with. He seemed positive about the experience enough to thank him.

MP3 playback is a feature to advertise with microcontrollers since WAV is usually default.
lavish patrol
Quick disconnect. 👍
sand lotus
the flat ribbon for enclosure internals is the way to go. ribbon cables are not good for internal airflow. microcontrollers don't require active cooling so they work great.
is that connected to adafruitio to track usage? report battery life if not connected to usb? interesting idea.
thinner slivers of lighter weight silk might get more movement from the fan.
the propmaker has 5v out? didn't know that.
lavish patrol
Also, since the fan is inside the case, maybe there's not enough airflow as there's nowhere for the air to get into the case.
sand lotus
the propmaker is really great and usually in high demand every halloween
the window idea will give it some airflow
sand lotus
When shopping for fans always pay attention to CFM (cubic feet per minute). Higher CFM also means a louder fan. There's a balance between CFM and noise.
unreal bay
you make me want to stick a 24v exhaust blower fan, like 3d printer style, go from low to high depending on sensor value / temp
wise iris
lights that count down to bedtime, or show it's not time to get up yet in the morning are popular too
sand lotus
Yes but do you really want a 24v 3D printer fan next to your head while trying to sleep. It would produce white noise enough where sound effects wouldn't be needed.
The speaker is where the battery JST normally is? Is that kinda dangerous? Is it possible to accidentally plug in a battery where the speaker goes?

The sound file is an approximation. It's a translation of radio waves to audio because in the vacuum of space there is no sound.

I wanted some short pin headers for a project but Adafruit was out of stock. So neat tip, to cut longer pin headers straight lay a piece of tape across the pins so you cut them all straight, works great.
The inducter in the mini boost helps cut down the ringing? Or you could wire in an inductor in line with the speakers.
A ferrite core can help with noise suppression. It's the same thing you commonly find on the end of power bricks, vga cables, etc..
streamers is a good idea, those are really light.
lavish patrol
Nylon cloth should work.
wise iris
flagging tape might flutter nicely, too
sand lotus
that's a good idea, the nylon or plastic is more durable. can't tug on streamers too much.

An octoprint feather controller wow. Hope that becomes a guide, that's great!
I'm still waiting for my Pi 4 to arrive to run octoprint.
Some 3D printers do have audio, there's gcode for an audio buzzer.
I can't remember which command but it does exist.

With a feather controller in the mix you can easily add audio notifications. Heck have it send a notification to your phone from adafruitio... i want to learn more about this setup! Looking forward to it!

You’d need a huge build volume to print the top and bottom enclosure for something like that.

Not having a big enough printer is an an issue i ran into right out of the gate. Sections introduce alignment issues too.

core argument validation of what? bitmap validations? i thought bitmaps were kinda taken care of for validating bits? maybe not?
nova totem
there is an issue I think where you cannot pass 32 bits. e.g. bitmap(2**32) is too big a number for the int in the core code so you can't set it to 32
sand lotus
oh is this more Blinka land?
nova totem
%x in mp_printf will print hex
wind spoke
16 is 0x10000 ... if you shift 4 you are left with the 0x1 (0000 dropped).
Sorry not 0x but 0b !!!
It is binary not hex.
nova totem
I think the idea is if each pixel is X bits. Shift them all out. If anything is left then the original number needed more then X bits to store so too big
wind spoke
So it is integer division by 16.
modern night
bit shifting is really fast so I think this is an optimization to handle this check quickly
wind spoke
You use that for 0bRRGGBB and you want to get 0bRR the red component. (or that kind of trick)

Would be nice to have Python style indexing including slicing for bitmaps. Finding slice objects to be pretty handy for manipulating palettes including using calculations via ulab. The CircuitPython ulab creator is thinking about bitmap image creation and effects in ulab, so future support for slice objects in the core might become a thing. 🤞
brazen quail
Hola from 'rado ! 😄 
nova totem
Slices should be possible. They are in pixelbuf
oh yeah the multi part i'm not sure on
inner spade
Perhaps bitmap[0:4][12:49:2] to be more Pythonesque
nova totem
I have been thinking coming up with a mini roadmap/future plan for DisplayIO would be useful. I've been spending too much time thinking about it lately though
Yeah his last TileGrid PR had a lot of good ideas
It can drive a SPI bus I think, but not sure if it would speed it up or not.
inner spade
How about PIO for parallel displays?
nova totem
Parallel already uses PIO
I wrote it 🙂 At least if my memory isn't failing it does
Yeah RP2040 parallel
sand lotus
Pretty sure Lady Ada said parallel will be disabled on most new eyespi boards because it offers no advantages over SPI with ESP and higher clocked chips. Think that was in a desk of lady ada about a month ago...
inner spade
PyPortal TFT is parallel if I recall correctly.
sand lotus
The ILI board is parallel yes
The HX like the tft featherwing isn't parallel. :/
I think the ILI will be the last one though, I think it's disabled in the new rev of the ILI display.
nova totem
The quick the PIO read seems to be faster then peripherial. They have a transmit only aimed at ST7789
modern night
Gotta head out a bit early, thanks for the stream!
nova totem
But... (there is always a but) after looking at the trace from my Saleae the majority of the time is still waiting on the CPU not the bus 😦 On a basic example almost 10-1
sand lotus
See ya KeithTheEE, have a good night.

Rewrite FourWire as PIOFourWire or something as a test
I am going to try to write up some displayio findings on speed and my GIF work, this weekend or next week
There are some good tutorials on getting the pico sdk examples running on a pico. They're just native C but prints work
sand lotus
Please do, i'm very interested in animated gifs. The 7 fps you're getting is already 2x faster than I could do with full screen animated 8-bit BMP sprites.
nova totem
As an example each solid(ish) line is writing one row of pixel data out. The gap between is all the work preparing the next row. Multiply that by 240. (those gaps are just under 1ms each)
sand lotus
I was told at the time it was a limitation of the SPI bus, not the display.
nova totem
In an absolute ideal world you need to transmit 11 bytes to set the row/col and say data is coming then pixels*16bits each.
CPU/complexity/FPU availability and more all figure in to it as well.
sand lotus
That was on the NRF52840, tried running the same thing on an ESP32-S3 and still got the same FPS.
Even tried overclocking the display which gave me like 1 more FPS.
nova totem
M4 has the floating point and I'm curious the speed diff on that. But I haven't tried profiling it yet. Once the GIF work is done I may try to set up something to try it out on a bunch of MCU
sand lotus
from 30hz to 72hz, something like that.
nova totem
Jeff also had some good points about bus sharing and DMA in his PR
sand lotus
Some displays can be overclocked but from my experience it makes no difference.
Maybe the CPU has to be overclocked? I heard the reason the DVI/HDMi on the pico works is because the Pico has to be overclocked?
nova totem
Overclocking the CPU would help but I think there are optimizations yet to be gained. I cut out a bunch of code (as a proof of concept) and got the 950us or so delay down to 172us.
sand lotus
Except the Pico by default isn't nearly as fast as an ESP32-S3.. I'd be interested to see that DVI/HDMI stuff done on the S3... might even be able to get it to 60 FPS if it's highly dependent on the CPU clock... ahh the ESP32-S3 doesn't have PIO. :/
or state machines i should say specifically
nova totem
Each bus write (at 33Mhz) is about 170us so with DMA you could almost have the bus at 100% utilization while rendering one refresh. Processing between frames is separate
sand lotus
Yup I ran into a hard lock on the display overclock at 33.3 exactly.
nova totem
(micro seconds but I don't have the micro symbol handy ha)
sand lotus
There was some kind of update that no longer allowed me to hit 72hz, it started artifacting at 33.3
If you would have told me a year ago I would get into overclocking microcontrollers I would have said nah lol. Projects kind of lead themselves down unexpected paths.
From 950 to 172 is a considerable improvement for sure. I was just probing I wasn't able to actually modify any code to improve it like you. Your doing awesome stuff.

Looks like he meant to write something different, the 8-bit format perhaps.

with blinka on it would be neat
animated gifs have a delay parameter so you can set how long each frame displays for. delay is built in for proper gif handling, can also ensure smooth playback as a time validation sequence kind of.
I have a 10 year old logitech c510 720p webcam i lost the housing for. Now that I have a 3D printer can actually give it a case again. Yes I've been using a bare PCB webcam for a decade lol.
Been using my soldering 3rd hand alligator clip to keep it positioned.
i freaking love 3d printers
Building the new one to have the 1/4 20 standard camera screw.
Most new webcams have them, most old ones didn't.
Going to use it for octoprint whenever the pi 4 gets delivered.
