Data Format
When pressing the touch panel, the controller generates X-Y coordinates of the pressed
Baud Rate: 9600, 19200 bps (ELO Mode: 9600 bps)
Data Bits : 8 bit
Parity
Stop Bit : 1 bit
The origin of X and Y axes is at the bottom left corner with proper line connections.
T as a header for pressing the touch panel, and R as a header for releasing it
Position values of both X and Y are from 0 to 1023 in decimal
