CMSIS-DSP on RP2350 | RP2350 #13

Installing and using the CMSIS-DSP library on RP2350. We will also be comparing the performance with the same library running on STM32. The video contains a bit of a surprise as to the floating point performance of RP2350.

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.

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?
