im using the feather nrf52832 with the featherwing.
i can read the ID by sending 0x00 as [0x80,0x81,0x00] = getting 0x0811
i tried to do the same with TSC_DATA_X 0x4D , but i can read any data from the sensor.
my init is :
writeRegister8(SYS_CTRL2, 0x0C); // Enable TSC and ADC Blocks
writeRegister8(INT_EN, 0x01); // TOUCH_DETECT-Interrupt are enabled
writeRegister8(ADC_CTRL1, 0x49);
writeRegister8(ADC_CTRL2, 0x01); // ADC Clock = 3.25 MHz
writeRegister8(GPIO_ALT_FUNCT, 0x00);
writeRegister8(TSC_CFG, 0x9A); // Panel driver settling time: 500us
writeRegister8(FIFO_TH, 0x01); // Not zero value
writeRegister8(FIFO_STA, 0x01); // Clear the FIFO Memory Content
writeRegister8(FIFO_STA, 0x00); // FIFO back to operation mode
writeRegister8(TSC_FRACT_XYZ, 0x07);// Data Format for Z-Value
writeRegister8(TSC_I_DRIVE, 0x01); // Choose 20mA driving channel
writeRegister8(TSC_CTRL, 0x03); // Enable Device, No tracking index, X, Y, Z mode
writeRegister8(INT_STA, 0xFF); // Clear all interrupt status
writeRegister8(INT_CTRL, 0x03); // Enable the interrupts
// define initial Touch Window
writeRegister16(WDW_TR_X, 0x0FFF); // Top Right X
writeRegister16(WDW_TR_Y, 0x0FFF); // Top Right Y
writeRegister16(WDW_BL_X, 0x0000); // Bottom Left X
writeRegister16(WDW_BL_Y, 0x0000); // Bottom Left Y
