Awesome idea: use Pi Pico as USB sound card + DSP! Equalizer, crossover, room compensation, etc.

So here's where the project sits at the end of day 1 - It's a #Blackberry Q10 keyboard working through a #PiPico #RP2350 controller. I'm making a physical keyboard case for my phone because I'm outrageously tired of virtual keyboards.
That's a PMOD implementation of the Q10 keyboard by Solder Party (shout-out to @arturo182) - I don't think you can buy these anymore but I bought two of them years ago and squirreled them away for the day I'd have a suitable microcontroller for the project.

For the ~3 other #Arduino folks on the planet trying to solve the same problem I am: if you're desperately trying to find a 3.3V version of a #ProMicro with USB type C, Sparkfun make one with a Raspberry #PiPico RP2350 on board - much faster chip than an Atmel 32U4, runs at 3.3 volts, and no more expensive, plus there's the usual exciting range of faithful and creative clones on AliExpress.
The RP2040 also runs at 3V3 but is tolerant of 5V, for those weird in-between projects. #electronics

And the results are in!
- Pico C
- Rust
- Free Pascal
- Joint with Pico C++, MicroZig and Yarg.
So, what am I going to do? Well, I'm leaning towards porting the existing Arduino C code to the Pico C SDK. I'm currently using one class for encapsulation and abstraction, but I could replace that with structs and static functions. I'm not a great C programmer, but I'm pretty comfortable with it, so it makes sense
However, before I do that, I see a bigger challenge of getting a good setup without using VS Code. I've been using #NeoVim for a while now, and I'd like to get a comfortable setup using that on #Linux.
So, I'm going to try to build Blinky projects for at least Pico C, Rust and Free Pascal, using Linux and NeoVim. Hopefully this will give me a better feel for how well these languages actually suit me. I've never done any Rust before, either, so that's going to be quite the learning curve!
If I have time, I'm going to give Yarg a go, too, because I think the premise is really cool. If I'm on a roll, I'll try #MicroZig too.
And if I really feel like I have the capacity, I'll port the code to one of these other languages.
I'm acutely aware of all the other projects I've given myself to do, such as the SIBO SDK and other small Psion-related projects, not to mention $dayjob and $reallife. So we'll see how things go!

RE: https://oldbytes.space/@thelastpsion/116345290344668595
Only a couple of hours left for this poll.
C is clearly out in front for my embedded project, but Rust and Pascal aren't far behind!

Poll for a bit of fun. Feel free to boost!
I've got a #RaspberryPiPico project written in #Arduino C. It talks to a Psion SSD and dumps the contents over USB serial. It can (theoretically) act as a full controller to tag an SSD, too.
I feel like I should port it to the proper Pico SDK. But I also know there are other options. And I'm intrigued to know what Fedi would do.
What should I rewrite this firmware in?

Made some progress on prototyping a #RP2040 based #USB Audio interface. I got a PIO program to output a good looking TDM signal for 4 channels of 32-bit samples.
Now I can start prototyping the receiving end of the transaction, DMAing samples into RAM and packing them into isochronous USB packets.

What can I say.. Lots.
* Raspberry PI (#PiPico', freely documented and with open source toolchains)
* Expressif (#esp32, ESP-IDF is quite open, and there are other fully open source toolchains. Documented by everyone, everwhere.. :-) )
* #WCH, makers of the infamous WCH-CHV 1cent 32bit risc-v mcu are growing, and their ecosystem seems to be developing nicely. Mostly in China but a lot of that ends up getting translated.
* #stmicro; mostly propitiatory tools, but also open source alternatives and a very healthy ecosystem in industrial circles.
* Others that I am forgetting about, the #8050 is still popular, for instance.
* And, weirdly; #Arduino (forked). There are huge chunks of their ecosystem that are already fully open source and qualcomm cannot touch. -

If you’ve written a Windows application that can read the Serial Number/Unique ID, or even the Vendor ID or Product ID of a microcontroller board (Pi Pico in my case) I’d appreciate any pointers.

I want to learn about this pattern where you write to a video memory area and then that gets processed separately and displayed on a monitor or VGA or what not. Maybe even something like what the #GameBoy does where tile maps and blit is done separately based on what you wrote to the video memory region. Does anyone know of any resources to implement something like that with #PiPico or #Arduino?
Two microcontrollers, where one writes directly into the other's memory, and the other does whatever processing and outputs video? I don't know if this is necessarily something practical I need to do, but I'd like to learn more about it. I've been reading about using DMA to communicate via SPI or UART and it reminded me of this.

I don't hate this usage of Ai,
I have notes on the execution but I thought I should fess up to not being anti-useful-not-wasteful-technology.
