ESP32 RMT peripheral IR library

Arduino friendly IR library utilizing ESP32 RMT peripheral

Protocols supported (send, limited receive):

NEC
SAMSUNG
RC5

What's new

IR code is now decoded correctly (NEC and SAMSUNG, RC5 needs a bit of extra work).

NEC sometimes decodes odd values, but might be down to config or cheap remotes.

I am happy with the prototype. This is the last commit before a big refactoring.

Example

#include <RMTLib.h>

RMTLib RMTLib;

const int TX_PIN = 27;

void setup()
{
  Serial.begin(115200);
  
  RMTLib.setTxPin(TX_PIN);
}

void loop()
{
  Serial.println("sending command");

  RMTLib.sendNEC(0x5743C03F);
  delay(5000);
}

TODO

Receive and decode (Arduino)
Repeat/toggle functionality
Refactoring current prototype level code

Planned

Examples to send/decode IR code through WIFI (Web, MQTT or CoAP)

History

Version 0.3b

Added SAMSUNG decode and started on RC5 decode

Version 0.3

More reliable receive code (NEC only)
Added extra debugging

Version 0.2a

Added initial receive code for NEC (IR code is decoded but bits are reversed)
Massive code refactoring (planning to support Arduino IDE + ESP-IDF toolchain with Eclipse)
Fixed RMT_CLK_DIV, 80 instead of 100

Version 0.2

GPIO can now be set at the beginning

Version 0.1

Initial version

Arduino library with example sketch
Send only
