I'm looking for ideas on where to start designing a circuit to send serial data between a set of uC's (Arduino & Raspberry Pi). I need to encode data, transmit it on top of a 24VAC/60hz wire, and decode it at the other end. The data is digital -- speeds around 19,200 baud or better would be ideal.
I was considering:
Using a single PLL on a chip, like a 4046 to decode the data... or even an HT12E / HT12D encoder/decoder (433 Mhz) to do the dirty work of encoding data from/to arduinos?
...also considered were using a 555 encoder paired with a 565 PLL decoder using frequency shift detection? (think it would be sloooow however)
Does anyone have a suggestion on where to start a sample / intro to RF serial digital data decoding/encoding? The carrier frequency can be ANYTHING except 60hz...
Any input is appreciated!
