- Capture IR Burst from any IR remote. Send captured or any predefined IR burst.
- Minimal use of CPU cycles. Completely based on PPI Channels
- This will work irrespective of the IR Protocol
- Tested with nRF SDK v15.3 & nrf52832 custom board (IR LED + TSOP38238)
- Required nRFX drivers PPI, Timer, LOG, Clock
- Have to be in 64MHz HFCLK
- Refer to the complete example project in Segger embedded studio
