NEC Protocol on nRF54

Ellan_Xeleqt

Good day,

I am currently working on a project involving the nRF54 series and would like to inquire about support for the NEC infrared (IR) communication protocol. Specifically, I am interested in:

  1. Whether the nRF54 supports receiving and decoding NEC protocol IR signals natively.

  2. Recommended peripherals or libraries for implementing NEC IR communication.

  3. Any sample code or references related to NEC IR decoding or transmission on the nRF54.

Any guidance or documentation you could provide would be greatly appreciated.

Thank you for your time and support.
Ellan

    For those remote type IR protocols there is (usually) a lot of legwork already done by the fully integrated IR receiver. Which you will need for the analog stuff too (light rejection, noise filtering, agc, etc).

    These typically spit out an already decoded digital signal. OTOH i believe we used just an UART to decode it - but its been quite a while, I might be wrong. Better read the datasheet of the receiver component.

    Transmitting should be a simple task for the PWM peripherial.
