Simple program to read the configuration of a GT911 touch panel.
Output is via USB. Under linux it will identify it self as /dev/ttyUSB*
The connections for the panel are on pins: PB10 --> SCL PB11 --> SDA Don't forget to add the 2K2 pullup resisters to the 3.3V on each line
It waits untill a key is pressed and will then read the configuration from register 0x8047 until 0x8100
