I've recently been designing a custom implementation of a DCC controller for a new model railroad I'm setting up - what don't you like about the protocol?

I find the protocol fascinating in that the data signal is combined with the power, so you just run everything over the two tracks.

Further, a transmitter is just a simple H-bridge that costs pennies...

It gets hacky when you want to read out CVs, since the DCC protocol is one way only. You need a good current sensor since most decoders encode the values into the current flow using the motor. It's a cute hack and somehow akin to morseing out with power LEDs.
