[modifier] Principle analysis

The Me LED Matrix contain 128 pieces of matrix LED.There are 8 piece per line and 16 per row. The main board sends the data to module through I2C bus, and LED control specific chip in module can handle the data and interpret it. And output relative signal to power on or off the LED. Make them display the content.
