PicoNet.1 Physical Layer
The physical layer is one bidirectional open-drain line pulled up to +3.3V using a 1KOhm resistor.Four symbols can be transmitted varying the time the bus is asserted down using an output mosfet:
- One
- 15ms down followed by 45ms up
- Zero
- 45ms down followed by 15ms up
- Break
- 90ms down followed by 30ms up
