Incorrect data in FIFO mode

[entrop1a]

In Example05_FIFOBuffer, when variable numSamples is greater than or equal to 22, the data obtained from the FIFO becomes incorrect.

No changes were made to the example.

Below is an example of the correct output for the device in static condition, with numSamples = 21.

It can be observed that the first sample is consistent with the actual state of the device, but the other samples correspond to movement, which is incorrect.
