GT911 register map
The is the architectural blueprint used to interface with the Goodix GT911 capacitive touch controller. It defines how a host processor (like an STM32, Arduino, or Raspberry Pi) communicates via I2C to configure the touch panel, read coordinates, and manage power modes. gt911 register map
0x8140 – 0x8177
Defines screen resolution, touch thresholds, and sensor layout. Coordinate/Status Registers
0x8040
The register map is divided into three primary functional areas: Address Range Access Type Description Command Register Write Only Sends high-level commands like Sleep or Calibration. 0x8047 – 0x8100 Configuration Registers Read/Write
