Can GLICOL run on an embedded Arm Cortex M4/M7?

[znmeb]

I've got a couple of Teensy 4.1 boards and a couple of Electro-Smith Daisy units. The Daisy ones have audio hardware; the Teensys are just the bare boards, although I could buy audio add-ons for them if they'll run GLICOL. Both have SD card capability.

The Teensy is a 600 MHz Arm Cortex M7 with 7936K flash and 1024K RAM. The Daisy is a 480 MHz Arm Cortex M7. I'm not sure how much flash and RAM the Daisy has; it's not on their website. Both are programmable / flashable via the Arduino IDE. Can GLICOL run on either or both of these?

Thank you for your question.
I also have STM32F3 and some ESP boards.
In theory it should be able to, but it may require some hacking for now. I will try to test and make the process easier in the coming days.
The key is to make Glicol support no_std. Yet two dependencies of Glicol, petgraph and pest have not supported no_std in main releases. There are already some successful forks of these two packages that successfully implemented no_std but not yet merged.
pest-parser/pest#498
petgraph/petgraph#370
I will test by depending on the forked git soon.

You get already get started by reading:

Especially the:
The Embedded Rust Book
For audio, I am pretty sure that DASP can support no_std:
https://github.com/RustAudio/dasp
For Bela or Pi, it should be more straightforward, although I will still need to change things to support features like ADC on Glicol.
Yet to use Glicol syntax or Glicol synth on no_std env, please stay tuned.

Thanks! I have three Belas - two of the full-sized ones and a mini with the eight-channel add-on. I'll start with a Bela to get the toolchain set up. I also have a Jetson AGX Xavier I can use for cross-compiling if necessary - full Ubuntu 18.04 and soon 20.04.

You can start with these repos:

https://github.com/padenot/bela-sys
https://github.com/andrewcsmith/bela-sys
And try to get a hello world tone there.

Thanks! I guess I need to buy one of those maker kits with potentiometers. :-) I already have three Belas and plenty of breadboards.
