reading zeroes from IIS3DWB FIFO

[mete]

Sometimes, I am reading zeroes from IIS3DWB FIFO. I thought maybe it is because I am using a protoboard (using MKI208) so I connected it directly (with cables) to RPi 4 but it still happens.

I guess it is not normal to find these in FIFO, can it be due to SPI communication/electrical issues ?

That was a bug in the code, no issues now.
