Connect the GT9xx touch ribbon cable to the 6-pin input on the driver board. Connect HDMI from the Pi to the board. Power the board via USB (5V/2A recommended). B. Configuring 1024x600 Resolution
TR-GT9XX-1024x600-01 Date: October 2023 (Updated for 2026 context) Subject: Integration and configuration of Goodix GT9XX family (GT911) for 10.1" to 10.4" displays at 1024x600 resolution.
This combination is widely adopted by leading embedded solution providers like , which uses GT9xx drivers for its 4.3-inch and 10.1-inch LCDs, Flylink (飞凌嵌入式) , Forlinx , and various industrial display manufacturers.
const uint8_t gt911_config_1024x600[] = 0x80, 0xD0, // Register start address // Config bytes (partial example) 0x04, 0x00, // X resolution: 1024 (0x0400) 0x02, 0x58, // Y resolution: 600 (0x0258) 0x05, // Max touches // ... (other tuning params: threshold, noise reduction, etc.) 0x00 // Checksum placeholder ;
For bare-metal or RTOS projects, driving a GT9XX1024x600 requires a (LTDC peripheral on STM32F429/F7/H7 series) or an external LVDS transmitter (e.g., TI SN75LVDS83). The GT9XX touch side uses standard I2C.
Proper device tree (DTS) configuration is critical for correct GT9xx touchscreen operation. Here is a typical device tree node for a GT9xx touchscreen:
The architecture of a typical gt9xx1024x600 system can be thought of as having two primary data paths: one for video data (LCD) and one for touch data (touch controller).
This hardware configuration is the backbone of millions of devices, ranging from budget Android tablets and single-board computer (SBC) displays (like those for Raspberry Pi or Allwinner chips) to and industrial human-machine interfaces (HMIs).
Ensure the metal frame of the screen is properly grounded to the controller.
In a Linux environment, you must define the touch size in the device tree source (DTS). A typical node looks like this:
First, let’s talk about the resolution. is effectively WSVGA (Wide Super Video Graphics Array). It sits perfectly between the old 800x480 standard (common on 7-inch displays) and full 1080p.
After boot, you can verify touch functionality using command-line tools like cat /proc/bus/input/devices to check for the input device, or use ts_test for a graphical touch test. Ensure the GPIO and I²C pins are correctly mapped in the device tree to avoid hardware detection issues.
