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

RE: https://oldbytes.space/@thelastpsion/116345290344668595

And the results are in!

1. Pico C
2. Rust
3. Free Pascal
4. 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!

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?

From the #DECtalk Mini github repository I commpiled with the #Pico-SDK today the RPi #RP2040 Pico version and changed it
from USB serial 115.200 Baud
to GPIO0/1-TTL-Serial 9600Baud.
Sounds fine on the left 3.5mm Audio channel
(GPIO28/Pin 24) of a
#Olimex RP2040-Pico-PC Board :)

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.

New #MechanicalKeyboard day! It's a #Kiser Monorail 45% #keyboard which I recently bought from @opendev on #40sDay in the Fediverse. I've put #HolyBoba switches in the #Kailh #hotswap sockets and put MiTo's GMK Laser keycap set plus some novelties on.

And yes, the #KiserMonorail is #V4N4G0N compatible, so it's my fifth keyboard with #TheVanKeyboards #Minivan-style layout.

It runs #QMK on an #RP2040 and uses easy peasy #Vial for configuration!
