ESP32 RMT peripheral IR remote control library for Midea Air conditioner.

Arduino friendly library utilizing ESP32 RMT peripheral.

Schema

Usage

Copy the files to your documents\Arduino\libraries\esp32_arduino_rmt_midea_ir_tx folder

Example

#include <Arduino.h>
#include <midea_ir.h>

const uint8_t MIDEA_RMT_CHANNEL = 0;
const uint8_t MIDEA_TX_PIN = 4;

MideaIR ir;

void setup()
{
    // init library
    midea_ir_init(&ir, MIDEA_RMT_CHANNEL, MIDEA_TX_PIN);

    // set mode, temperature and fan level and internal state to enabled
    ir.enabled = true;
    ir.mode = MODE_COOL;
    ir.fan_level = 3;
    ir.temperature = 23;

    // send the IR signal with the previously set properties which will switch the A/C on
    midea_ir_send(&ir);

    delay(5000);

    // starts moving the deflector
    midea_ir_move_deflector();

    delay(5000);

    // set state to disabled
    ir.enabled = false;

    // send the IR signal which will turn the A/C off
    midea_ir_send(&ir);
}

void loop()
{
    delay(1000);
}

Thanks

A big thanks goes to @sheinz His library was used as a base as it was very easy to replace the signal sending part of it with my implementation.

Without the following pages this software couldn't exist. They contain very useful information on how the protocol works.
