Hello,
Im trying to interface LIS3DH with nRF52DK referring this example https://devzone.nordicsemi.com/f/nordic-q-a/34710/lis2dh12-driver-issue-in-nrf-sdk-v15-0.
Im getting the following result, the control doesnt enter "print_identity " function and the results are as follows,
Can you help me find out how to read the values of acceleration with this code and interpret the value read?
