Hi Nick

I was wondering what this line does?
Code: [Select]
(accel.GetINT1ActiveInterrupt() & LIS2DH12.INT_ACTIVE) = LIS2DH12.INT_ACTIVE
You've said that you use accel.GetINT1ActiveInterrupt() to clear interrupt but why compare LIS2DH12.INT_ACTIVE to itself?
If I wanted to clear all interrupts in the INT SRC register, how long would I have to loop for?
Something like this?
Code: [Select]
    INTMSG = accel.GetINT1ActiveInterrupt()
While ((accel.GetINT1ActiveInterrupt() & LIS2DH12.INT_ACTIVE) = LIS2DH12.INT_ACTIVE)
