DCC and microcontrollers

Does anyone have any good design references for generating and decoding DCC signals using a microcontroller? Interface circuits, source code, possible target devices for development?

I’m a bit confused on DCC, is it bi-directional?

Dave Bodner uses some kind of interface so he can use JMRI on his laptop. He had it set up at the one train show, to show the signals on the rails.

Bi directional, yes there is some communication from the decoder back to the controller. But I do not know how much.

To answer my own question, or at least one of them- here are a couple of simple circuits I found after googling about for a few days:

A 3A booster circuit, which (I assume) would allow me to send DCC commands:

And a simple decoder:
