CC1200 ASK mode for PPM demodulation?

Other Parts Discussed in Thread: CC1200

Is it feasible to use the ASK demodulator on the CC1200 for PPM (pulse position modulation) decoding? Packet decoding on CC1200 not necessary, this can be done by the host MCU, basically the CC1200 would only detect the carrier pulses as ASK and the MCU would measure the interval between each received pulse to correctly decode them as bits.

  • Yes, using OOK should work

    Two potential ways to do this:

    - Use transparent mode and let the MCU measure the pulse width

    - Set the datarate to the shortest pulse time used and use sync. serial mode or packet mode to partially offload the MCU.
