): Sitting atop the display is a capacitive glass substrate managed by a Goodix IC. The GT9xx family communicates with the host system over an . It converts spatial capacitance shifts (finger presses) into raw pixel coordinates, supporting up to 5 or 10 simultaneous touch points. Understanding the GT9xx Configuration Matrix
defines the number of supported touch points (typically 5 for GT911 or 10 for GT9271). Crystalfontz 2. Device Tree (DTS) Integration
This is easier. Use the GT911 library by tobozo or m5stack .
The GT9xx Linux driver typically consists of two files: gt9xx1024x600
Unlike resistive touchscreens (common in older 800x480 units), the GT9XX offers true capacitive multi-touch. More importantly, certain GT9XX variants include high-sensitivity modes for or water tolerance , making them ideal for medical, automotive, or outdoor kiosks.
Disclaimer: This post contains general research. Always verify your specific GT9xx chip revision against the official Goodix datasheet.
The GT9xx touch controller communicates over I2C. To enable it, you must run sudo raspi-config , navigate to "Interface Options", and enable I2C. Alternatively, you can add dtparam=i2c_arm=on to your config.txt file. ): Sitting atop the display is a capacitive
For those ready to start their own project, several open-source resources are available to accelerate the development process:
This report assumes the IC is the (the most common in the GT9XX family for this resolution), as the GT915 and GT928 share similar architecture but differ in maximum touch points and reporting ID.
The 16:9 aspect ratio is perfect for modern POS applications, where the 1024×600 resolution balances cost and readability. Use the GT911 library by tobozo or m5stack
The keyword breaks down into two distinct technical specifications:
Goodix 3rd generation Projected-Capacitive (P-Cap) technology. Channels: 26 driving channels and 14 sensing channels. 2. Pinout and Connectivity Datasheet - FORTEC Integrated
GT9xx self-calibrates at boot. However, if edges are inaccurate:
