Hi Wenbing,
I would consider a simpler scenario first. Consider only the parasitic capacitance between EVM (local) ground and earth ground. It can be modeled by Eq (4) and (5) in the application note.

Part Number: FDC1004EVM On page 7 of SNOA925, it shows CHX on top of SHLD1 and CHX is in phase with SHLD1. Then on page 9 Meas1 CHA is CH1 and CHB is CH4. Why is CHB shown as CH4 if CH4 is out of phase with the phase of SHLD1? Would think the CH4 would…
Hi Tom Hanks3,
You can refer to the SensingSolutionsEvm_Protocol_0v1 java script file for USB communication protocol between the GUI and the EVM. The file is located under PC GUI\node_modules\SspEvmNodeJS in the Sensing Solutions EVM GUI installation…
Hello,
Linux systems are quite capable of opening COM ports and issuing the same commands. Refer to stackoverflow.com/.../how-to-read-a-binary-data-over-serial-terminal-in-c-program

Part Number: FDC1004EVM The EVM GUI doesn't see the board. It reports it as 'unconnected'.
Tried different USB ports, rebooting, etc.
Seems that it hasn't installed the right drivers.
I've tried another test for approx. 1 minute. The CSV data log is showing 'evmSampleDeltaMs' and 'logDeltaMs' with the same values which is expected, however the sum of the column is only 29.93 seconds, half of what it should be. Why is this?
Thanks…
Other Parts Discussed in Thread: FDC2214EVM , FDC1004EVM Hello,
I just begin to use FDC2214EVM to read capacitance signals from my home-made sensors. However, I have some questions, and could you please help me with them? Thank you in advance.
