Gt911 Register Map ((hot))
High bit (bit 7) indicates if new touch data is available. Lower bits indicate number of touch points. Touch Data Registers
Here is a list of GT911 registers, including their addresses and descriptions: gt911 register map
Perform a sequential I2C burst read starting from 0x8150 for ( High bit (bit 7) indicates if new touch data is available
If you can tell me (e.g., ESP32, STM32, Arduino) you are using, I can provide a code snippet for the initialization or touch reading . Arduino) you are using
Contains the first point's X (high/low) and Y (high/low) coordinates, along with pressure data. Point 2 Data Data for the second touch point.
The lower 4 bits of register 0x814E tell you how many fingers (0–5) are currently on the screen.
