FXLS8471Q Auto-sleep with Transient threshold trigger
As of February 2, 2026, the NXP MEMS Sensor products have been transferred to STMicroelectronics. For details on the transferred products, see this page. Please reach out to STMicroelectronics for further information.
FXLS8471Q Auto-sleep with Transient threshold trigger
*************************************************************************************************************
* This simple example code has been written for the NXP FRDM-KL25Z + FRDMSTBC-A8471
* boards and demonstrates how to use the embedded transient detection function
* in conjunction with the auto-wake/sleep mode for reducing current consumption
* of the FXLS8471Q.
*
* The transient threshold is set to 312.5mg (5 counts) on the X and Y axis.
* Once this threshold is exceeded, the FXLS8471Q is waken up and an interrupt
* is generated on the INT1 pin. If the acceleration is below this threshold
* within the 1s period, the FXLS8471Q goes back to sleep mode and also
* generates an interrupt on the INT1 pin.
