Hi Clavier,      Thanks for your reply. You are correct. So, these below are the sequences that I will do when powering on and powering off the LIS3DH Accelerometer.       Powering On: Set ACC_VCC to 0, to turn on power to LIS3DH Accelerometer. Call SensorI2C_open(). Enable ACC_INT1 Pin.       Powering Off: Disable ACC_INT1 Pin. Call SensorI2C_close(). Set ACC_VCC to 1, to turn off power to LIS3DH Accelerometer. Best Regards, Marke
