  6. -----------------------------------------------------------------------------
  7. Configuration
  8. -----------------------------------------------------------------------------
  9. To enable transmit functions define IR_TX_PIN
  10. To enable receiver functions define IR_RX_PIN
  11. MQTT input topic: {root}/irin
  12. MQTT output topic: {root}/irout/set
  13. --------------------------------------------------------------------------------
  14. MQTT messages
  15. --------------------------------------------------------------------------------
  16. Decoded messages:
  17. Transmitting:
  18. Payload: 2:121944:32:1 (<type>:<code>:<bits>[:<repeat>])
  19. The repeat value is optional and defaults to 1
  20. Receiving:
  21. Payload: 2:121944:32 (<type>:<code>:<bits>)
  22. Raw messages:
  23. Transmitting:
  24. Payload: 1000,1000,1000,1000,1000,DELAY,COUNT,FREQ:500,500,500,500,500
  25. | IR codes | | IR repeat codes |
  26. codes - time in microseconds when IR LED On/Off. First value - ON, second - Off ...
  27. DELAY - delay in milliseconds between sending repeats
  28. COUNT - how many repeats send. Max 120.
  29. FREQ - modulation frequency. Usually 38kHz. You may set 38, it means 38kHz or set 38000, it meant same.
  30. Repeat codes is optional. You may omit ":" and codes. In this case if repeat count > 0 we repeat main code.
  31. Receiving:
  32. Payload: 1000,1000,1000,1000,1000
  33. | IR codes |
