Tested with Arduino Core for ESP8266.

Example

A simple example, turning the red LEDs on.

#include <my92xx.h>

#define MY92XX_MODEL    MY92XX_MODEL_MY9291     // The MY9291 is a 4-channel driver, usually for RGBW lights
#define MY92XX_CHIPS    1                       // No daisy-chain
#define MY92XX_DI_PIN   13                      // DI GPIO
#define MY92XX_DCKI_PIN 15                      // DCKI GPIO

my92xx _my92xx = my92xx(MY92XX_MODEL, MY92XX_CHIPS, MY92XX_DI_PIN, MY92XX_DCKI_PIN, MY92XX_COMMAND_DEFAULT);

void setup() {
    _my92xx.setChannel(0, 255); // assume channel 0 is RED
    _my92xx.setState(true);
    _my92xx.update();
}

void loop() {}
