IR NEC

M5StickCPlus2 IR驱动案例程序。本案例使用到了 Arduino-IRremote - Lib 来实现NEC编码。

#define DISABLE_CODE_FOR_RECEIVER  // Disables restarting receiver after each
                                   // send. Saves 450 bytes program memory and
                                   // 269 bytes RAM if receiving functions are
                                   // not used.
