Adding Custom IR Codes - xoseperez/espurna GitHub Wiki

  1. Open code/espurna/ir.cpp in your favourite text editor
  2. Find the presets location, currently inside of the ::ir::terminal::build::preset() function
  3. Make a copy of any IR code set, to allow us to modify it. Update the IR_RX_PRESET index as well.
  4. Use IRrecvDumpV2 or IRrecvDumpV3 to get IR Codes. You'd get something like this:
Timestamp : 002222.937
Encoding : NEC
Code : FFE01F (32 bits)
Library : v2.3.2

TODO: code example

The uint64_t data value is useful to us.

  1. Update the code(s) from the received data
  2. Don't forget to change the IR_RX_PRESET' value in the build flags or for the board of your choice in code/espurna/hardware.h`
