Yes, I’m using sys1.6 from macrosin and fpga 2.61.
In fact, this problem maybe is something about the hardware, because I find not like the schma, the v- is -2.8v but not -3v.
Now I have a v+ of 3v, maybe is the difference between V+ and v- caused this problem.
But after the calibration, other values are corrected. Is the RMS has a different way of calculation?
