  Ada drivers for the Raspberry Pi RP2040 SoC

AdaCore's docs are fantastic for understanding why things are done the way they are. However, when I'm learning a new platform or language I prefer to see a lot of practical examples first. That's what I tried to do with my "Ada on the Raspberry Pi Pico" project:

  Program the ESP32 with Nim! Wrappers around ESP-IDF API's.

Checkout Nim! I've used it to great effect for embedded programming. It has memory management system based on non-atomic reference counting (arc) so its fast and deterministic. It has optional cycle collection too (orc). Its easy to mixin manual memory as well.

I used F# a bit and learned a lot from it, and the same with Elixir. Nim is procedural it has an "enlightened procedural" take that feels like functional programming in some ways. Partly thats due to the very powerful type system - for example Nim lets you define custom distinct (not aliased) number types just like F#. Nim also inherits a fair bit from Pascal and so shares points with Ada like ints with custom ranges. Theres some rough points, but largely its made me enjoy programming again.

The esp32 is a good route since they're easy to setup. I wrote a wrapper for esp-idf which is used in production in at least two embedded shops: https://github.com/elcritch/nesper

You can run it on Arduinos as well. Theres a pure Nim setup called Ratel and a rp2040 wrapper too. :)
