Other Parts Discussed in Thread: FDC2214
Tool/software:
Hi, I'm testing a capacitance sensor measuring with FDC2214 EVM.
During measuring, I found such a threshold problem in signal.
Sometime, the signal is blocked like above figure and it does not change well near that value.
This phenomena has occur frequently in ch3, and also occur in other channels rarely.
I did try a lot of cases of reference count, settle count and other register values, but it still show.
How can I fix it?
Thank you.
