I would like to ask about ODR accuracy of MMA8451Q.
My customer has a doubt on the accuracy of ODR(+-2%) from their test.
The customer’s test is as below.
- Set up the ODR=100Hz by register.
- Set up the interruption from MMA8451Q when FIFO contains 16 data.
- MMA8451Q will issue the interruption with 160mS period.
As a result, they saw the interruption period from MMA8451Q could exceed from +-2%.
Is their test procedure is correct for ODR accuracy measurement?
Could you show me how to measure the ODR accuracy?
