[ragel-users] Best practice: using ragel for bit-based state machines on microcontroller?

Hello there!

I'd like to use ragel to design the state machine for a microcontroller
project (avr atmega8535) written in C.

I think I understand how to use it for streams of char, int, etc. But
what's the best practice to use for bit based decisions?

I could use union..struct to pack all bits in one datatype and process
that. But I doubt that'll yield a performant implementation.

I read messages on this list that ragel is used for uC projects, but no
details how.

So any hints or example code to get me started is appreciated.

Thanks in advance,
/Jan.
