The gt9xx1080x600 new is offered in a 6x6 mm QFN-48 package, identical to previous GT9 variants. However, the "new" version reassigns pin 37 and 38 to a dedicated I3C interface (Improved Inter-Integrated Circuit) alongside standard I2C. This allows for 12.5 Mbps communication, necessary for streaming raw touch data from the 1080x600 grid.
Pro tip: If upgrading from an older GT9 design, add 10Ω series resistors on the I3C lines. They are not optional due to higher slew rates.
Standard touch display combinations often use 800×480 or 1024×600 resolutions. However, 1080×600 (aspect ratio 16:8.9) is gaining traction for dashboard and handheld devices. The GT9XX series supports up to 1080×600 with firmware adjustments. This work proposes a new configuration procedure to achieve reliable touch performance.
The "New" revision typically supports three interface modes, selectable via hardware strapping:
Legacy controllers failed in wet conditions. The new model incorporates a multi-frequency mutual-capacitance scan. It can distinguish between a water droplet and a human finger at 1080x600 resolution by analyzing the phase shift returning from each of the 30-40 drive channels. Result? Full operation with rain spray or while wearing nitrile gloves (up to 1.5mm thickness). gt9xx1080x600 new

This guide covers the integration and configuration of Goodix GT9xx series (like GT911, GT927, GT928) capacitive touch controllers for a specific 1080x600 resolution, commonly used in automotive and industrial display panels. 1. Hardware Connection & Addressing
The GT9xx series uses a 6-pin interface: VDD, GND, SCL, SDA, INT, and RESET. The gt9xx1080x600 new is offered in a 6x6
I2C Address: Typically 0xBA/0xBB or 0x28/0x29 depending on the state of the INT pin during reset.
Physical Setup: Identify your I2C bus ID and the GPIO pins used for RESET and INT from your hardware schematic. 2. Resolution Configuration (1080x600)
To set the resolution to 1080x600, you must modify the configuration data sent to the chip's registers (starting at 0x8047). Linux: Adding GT9xx touchscreen drivers to AM335x SDK
The search term "gt9xx1080x600 new" likely refers to a Goodix GT9xx series capacitive touch screen controller configured for a 1080x600 resolution If you meant something else — for example,

The 1080×600 resolution pushes GT9XX’s nominal limit (max 1080×1920 recommended). The new configuration ensures stable touch detection but incurs a 13% reduction in report rate — acceptable for GUI applications not requiring fast drawing. Further improvement can be achieved by using the GT9XX’s “gesture mode” to reduce CPU load.
