to clear the buffer status so the chip can update with new data. Focus LCDs
A standard Goodix GT911 datasheet configuration block consists of 186 bytes. Below are the most critical registers you need to modify during initialization: gt911 register map
Use this method if interrupts are not available. Continuously read 0x814E in a loop. If the "buffer status" bit is 1 (i.e., a value like 0x81 for one finger), proceed to read the coordinates and then clear the register as described in Method 1. to clear the buffer status so the chip
The coordinates are formed by combining the high and low bytes: . It is crucial to handle this data correctly in your code. then release RST .
Drive RST low, drive INT high/low to choose your I2C address, then release RST .
