I've read about manchester encoding..but it's rather complex. does anyone has the C source for it?

First you have to send preambles for proper reception and sync word for every packet to ensure byte Synchronisation

Preamble is sent first and then the sync word then the actual data finally the CRC for error detection.I hope u got it.
