Gt911 Register Map =link= Jun 2026

utilizes the and RESET pins simultaneously during power-on initialization to choose between two unique 7-bit I2C addresses. This flexibility avoids address conflicts on shared hardware buses.

The GT911 register map had been a challenging but rewarding project. Alex had learned a great deal about the intricacies of the chip and the importance of accurate documentation. As the technology landscape continued to evolve, Alex was confident that the GT911 would remain a vital component in many devices. gt911 register map

: Buffer Status. Set to 1 by the GT911 when new touch data is ready. The host processor must clear this bit to 0 after parsing coordinates to receive subsequent interrupts. utilizes the and RESET pins simultaneously during power-on

Before executing your configuration routine, query the product ID registers to verify stable I2C communication and confirm that the connected hardware is an authentic Go to product viewer dialog for this item. Alex had learned a great deal about the

The GT911 organizes its control and data interface into a unified memory map accessed via a 16-bit register address. The memory space is divided into four distinct functional zones: Address Range (Hex) Registry Zone Primary Function Access Type 0x8040 – 0x80FE Screen resolution, touch thresholds, timings Read/Write 0x8140 – 0x8177 Coordinate Registers Touch status, point counts, X/Y tracking data 0x4100 – 0x43FF Command Register Soft resets, baseline updates, operation modes Read/Write 0x8000 – 0x800F Product ID / Version Chip name, firmware version, vendor ID 1.
