Hi Moto,
I did not get your questions. The Real Time Data tab of ADXL375 just show the real time output from ADXL375, no post processing. Or say, just use xxxLSB * scale factor and using the scale factor 49mg/LSB no matter what ODR it is.
Only 0x0001 will show as 0x0000 @ 3200Hz ODR, 0xffff (-1) won't show as 0x0000 @3200Hz.
Or say -1d not equal to 0. Again, the Real Time Data tab of ADXL375 EVB GUI just reflect the real time output.
