The is a popular capacitive touchscreen controller often paired with 7-inch 1024x600 portable displays . These screens are commonly used as compact monitors for Raspberry Pi, Arduino, or ESP32 projects due to their lightweight design and high pixel density for their size. Hardware & Connection Guide
Increase this value to require a firmer press, filtering out low-level capacitive noise.
: Configure your device tree source ( .dts ) file to define the GT9xx controller's properties. This includes setting the compatible string (e.g., "goodix,gt9xx" ), the I2C reg address , and the interrupt pin (INT) your hardware uses. gt9xx1024x600 portable
, is renowned for supporting 5-point or 10-point multi-touch via a standard I2C interface. When paired with a 1024x600 resolution—often referred to as WSVGA—the screen provides enough pixel density for readable text and functional GUIs without demanding the high processing power required by 1080p displays. Key Specifications of GT9xx 1024x600 Displays Resolution: 1024 x 600 pixels (WSVGA).
