STM32N6570-DK: need factory GT911 touch-controller config (RK050HR18C-B01)
The GT911 configuration (as far as I know registers 0x8047 - 0x8100, but maybe there is more?) on my module got overwritten by my experiments, and touch now has large dead zones, where no touch is registered at all. The driver/sensor channel map is specific to this panel and isn’t in any BSP, so I have no factory copy to restore from, and I also don’t have a 2nd board.
Could anyone with a working DK dump their GT911 config and paste the values? (Or does ST have the default config for this module, I sadly couldn’t find it anywhere?) From my understanding it should be as simple as:
uint8_t reg[2] = {0x80, 0x47};
uint8_t cfg[186];
i2c_write(0x5D, reg, 2);
i2c_read (0x5D, cfg, 186);
