TS-8390-47XX Touchscreen
From embeddedTS Manuals
The touch screen on the TS-TPC-8390 is comprised of a two channel ADC and a portion of the TS-47XX's FPGA. The touch controller's raw data can be accessed for a number of custom applications, including the collection of custom calibration data and polling for specific touch instances. This data is presented with two registers on the TS-47XX:
Address | Bit range | Function |
---|---|---|
0x80005000 | 15:1 | X touch position value |
0x80005000 | 0 | Touch Flag (1=touch) |
0x80005002 | 15:1 | Y touch position value |
0x80005002 | 0 | Touch Flag (1=touch) |
