I'm trying to decode a MVB train protocol using RP2040. The protocol is using special preamble for master and slave frames. Frame looks like:
11111 01100011100010101 01 10 01 01 01 01 01 01 01 10 01 10 01 01 01 01 01 01 10 01 01 01 10 10 0011111
Where 01100011100010101 is the master preamble. 101010100011100011 Any ideas how to detect the master/slave preamble with PIO? It could start Manchester decoding in another state machine with IRQ.
