Gt911 Register Map May 2026

Defines screen resolution, touch thresholds, and sensor layout. Coordinate/Status Registers

The GT911 uses 16-bit register addresses. It supports auto-incrementing , allowing you to read or write a continuous block of data in a single I2C transaction. 2. Core Register Map Structure gt911 register map

Contains the touch point status and X/Y coordinates for up to 5 points. Command Register (0x8040) The GT911 operates as an I2C slave

Depending on the state of the INT and RESET pins during power-on, the device uses either 0xBA/0xBB or 0x28/0x29 (8-bit write/read format). and manage power modes.

The GT911 operates as an I2C slave. Before accessing the register map, you must establish the correct slave address.

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.
