4 . IR Control Interface
4.1. Transmission Format
The transmission format consists of the transmission of a leader code, 16-bit custom codes
(Custom Code, Custom Code’), and 16-bit data codes (Data Code, Data Code) simultaneously, as
shown in Figure 4-1. Data Code is the inverted code of Data Code. The leader code consists of
a 9-ms carrier waveform and a 4.5-ms OFF waveform and is used as a leader for the ensuing
code to facilitate reception detection. Codes use the PPM (Pulse Position Modulation) method,
and the signals “1” and “0” are fixed by the interval between pulses.

4.2. IR command list
Custom code: 0x00FF

5 . UART Control Interface
5.1. Uart for data
Baud Rate: 115200/57600/38400/19200/9600bps
Formato datos: 0x01 + 0x88 + 0x00 + 0x01 + data + 0x03 + 0x00 + 0x00

5.2. Uart for X/Y coordinate
Formato datos: 0x01 + 0x88 + 0x02 + 0x02 + Byte1 + Byte2 + 0x03 + 0x00 + 0x00
Byte1 = Touch Location X; Byte2 = Touch Location Y;
nota: The full screen X/Y coordinate range is 0~255 ;The screen
left top corner coordinate is (0,0).
