@Sahil_K  It would be beneficial & time-saving If you can directly provide me with all your Files of yours ..HEX. GUI(EXE) . Most importantly zadig driver installer can detect.

https://community.infineon.com/t5/PSoC-5-3-1/Potentiostat/m-p/367399#M47600............... Please try to resolve this...

Is that required to lock the pins???? For this case, Vout is Counter electrode Vout1 Reference electrode Vout2 is WE. Let me know. Is that port important for connection wires externally or pin?

Port & Pin is different things? For example P3_0 its also for PSoc 5LP development kit & PSoc 5LP prototyping kit. Hardware connection is different?
