The touch 10

11 information type is as follows: 55 AA X Y. The touch information is encoded on the NEC IR signals. The format as following : 55 AA X Y. Since X and Y are 1 byte, the resolution of touch screen can only reach to 256 X and Y coordinates, you need to do transformation of scale: zoom in or out Coordinates of the touch screen mode by serial 1)Serial port settings are as follows: 2)ISDB UART protol Serial port command format for the touch coordinates "hcmd dn 0x24 0xdd 1 w pos", where pos = (unsigned int) (x <<16) + y; For example: car machine resolution (640 * 480), transmission coordinates (200,100),then the conversion of coordinates (100,50), where pos = 100 << = , then the serial port command format for the touch coordinates is "hcmd dn 0x24 0xdd 1 w ". Note: After each command to be sent '\ r' (0x0d). 4.3 Car machine key input 11
