Listing 1. Protocol for FS1000A.
It should be noted that a logical one in ASK modulation implemented on this board is equivalent to signal presence, and a logical zero is equivalent to no signal presence.

  • 2000 μs of logical one

  • 500 μs of logical zero

  • Data encoded with Manchester II [26]:

    • –

      Low-high transition for bit 0.

    • –

      High-low transition for bit 1.

  • 1000 μs of logical one, indicating the end of transmission
