Hi,



The emojis are stored in the firmware of the driver and when you call it from the code it gets the emoji data via I2C communication.



void GroveTwoRGBLedMatrixClass::displayEmoji(uint8_t emoji, uint16_t duration_time, bool forever_flag)

{

uint8_t data[5] = {0, };



data[0] = I2C_CMD_DISP_EMOJI;

data[1] = emoji;

data[2] = (uint8_t)(duration_time & 0xff);

data[3] = (uint8_t)((duration_time >> 8) & 0xff);

data[4] = forever_flag;



i2cSendBytes(currentDeviceAddress, data, 5);

}



If you want to display your custom emoji then you can follow this DIY part:
