The following table summarizes the typical specifications of a GT9xx1024x600 touch display module:
The driver is at /board-support/linux-/drivers/input/touchscreen/goodix.c. If you check the Makefile you will see this line: obj-$ TI E2E support forums gt9xx1024x600
The GT911’s I2C address is 0x5D by default, but if the INT pin is left floating during boot, it switches to 0x14 . Always pull the INT pin high (3.3V) via a 10k resistor before powering on to lock it to 0x5D . The following table summarizes the typical specifications of
Supports up to 5 or 10 simultaneous touch points depending on the specific chip variant. Supports up to 5 or 10 simultaneous touch
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.
Developed by Goodix Technology , the GT9xx series (which includes popular ICs like the ) consists of high-performance, capacitive touch controllers designed for mobile and embedded applications.
