# RP2040-decoder

This is a microzig-based rewrite of
[RP2040-Decoder](https://github.com/gab-k/RP2040-Decoder).

This is only the software part, the hardware is the same.

## Why

Because I wanted to learn RP2040 programming in zig.

## Is this any better?

No, right now it is not even finished, so You probably want to use the original.

# TODO

## Make it usable

 - Write flash handling, CV reading-writing part
 - DCC
	- S 9.2 Chapter B
	- S 9.2.1
 - PID: follow the blog post

## Plans

 - Replace DCC signal handling with some PIO assembly
 - Add sound support
