Firmware Registry Configuration gt9xx1024x600

Based on the keyword , this refers to a specific configuration for a Goodix GT9xx series capacitive touch screen controller (commonly the GT911 or GT9271).

An exemplary device tree node configuration binds the I2C bus to the touchscreen driver, establishing the boundaries for the 1024x600 coordinate framework: Run make menuconfig and navigate to the following

To configure a GT9xx controller for a 1024x600 screen, you must program specific registers starting from address Crystalfontz X Resolution (1024) : Written as a 16-bit value across registers (Low Byte: 0x00) and (High Byte: 0x04). Y Resolution (600) : Written across (Low Byte: 0x58) and (High Byte: 0x02). Touch Points : Register

The screen triggers random click events on its own, usually near the edges. An exemplary device tree node configuration binds the
