LIS2DW12 FIFO overflows upon wake-up by interrupt GreetingsI have configured the LIS2DW12, via SPI, to sample and store samples, given the FIFO (configured in continuous mode) on a wakeup interrupt to INT1. The sensor, given its current configuration is able to wake up and sample but there is a worrying issue where, on the first wake-up (providing some movement to the sensor), the FIFO always overflows. I am seeing this when my ISR fires and the data-read-function is called, and within the read function, I am checking for the overflow and then essentially returning an error. If I try waking it up again, it samples fine without overflow occurring.Any help would be appreciated to figure out why overflow occurs ONLY on the first wake-up.My current configuration is:Write(CTRL2 , 0X1E) //BDU ENABLED, I2C Disabled, IF_ADD_INC EN, Disable CS_PU
Write(CTRL6 , 0X10) //enable HPF, ODR/2, FS = 2G
Write(WAKE_UP_THS , 0X0C) //Threshold = 375mg
Write(WAKE_UP_DUR , 0X00) //No-wakeup time
Write(FIFO_CTRL , 0XC0) //continuous mo
