Gt911 Register Map !!install!! Jun 2026

First, perform a dummy write of the 16-bit address you want to read from. Then, issue a restart condition and read the data. Auto-Increment:

To help me tailor any specific driver code or schematic guidance for your project, please let me know:

is a popular 5-point capacitive touch controller that communicates via

When writing code for an open-source project or custom hardware stack, follow this sequence to interface with the register map safely: Phase 1: Initialization gt911 register map

during startup to verify you are talking to the correct hardware before applying configurations. ESD Protection: Regularly write and check the value at register if your device operates in high-interference environments. 3. Register Map

Below is the definitive register map for the GT911. All addresses are 16-bit. Note: The GT911 uses Big-Endian (MSB first) for multi-byte values.

Enables/disables features like gesture recognition. 3. Register Configuration Workflow (Example) First, perform a dummy write of the 16-bit

Write the configuration bytes to the registers starting at 0x8047 .

Suspends touch scanning to preserve power. Wake up the chip by pulling the INT pin high for at least 5ms.

0x00 : – Standard operational mode for standard multi-touch tracking. ESD Protection: Regularly write and check the value

Poll 0x8101 first. If it returns >0, then read the touch data.

The GT911 register map is not beautiful. It’s not a work of art like an I2C accelerometer with neat, aligned 16-bit registers. It is a . It is brutally efficient.
