Contains the touch point status and X/Y coordinates for up to 5 points. Command Register (0x8040)
This register is used to trigger specific device states. Common commands include: 0x00 : Read coordinate status. 0x05 : Enter to save power. 0x06/0x07 : Enter/Exit Charge mode for enhanced sensitivity. Configuration Registers (0x8047+) gt911 register map
This block is often sent as a complete "config array" during initialization. 3. Register Map Contains the touch point status and X/Y coordinates
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. 0x05 : Enter to save power
Understanding this map is essential for developers writing custom drivers or troubleshooting touch response issues in embedded systems.
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
