Posted on November 27, 2017 at 09:10Hello All,I configured ODR to 1600Hz at CTRL4 register on LIS3DSH.It works perfectly except for update frequency.INT1 pulse outputs with 600us interval! I attached Oscilloscpe at INT1 pin.It should be 625us(1s/160...

Posted on November 28, 2017 at 06:03I have one more question.How much % is frequecy error of INT1 interval in worst case at LIS3DSH product?For example, 1600Hz+-10% or something.It is necessary for calculating buffer size for interpolation.

Posted on November 28, 2017 at 04:05Thank you very much for useful information, Miroslav.I will use something like interpolation in order to get fine value.

Posted on November 27, 2017 at 15:12Ok, I understand it is spec.So if I want to get INT1 interrupt with exactly 625us interval, what should I do?
