Amperometric Measurement with different pins from the examples

So, from doing some research in this forum I think I misunderstood the code and it's not doing the measurement via Vzero and AIN4, but via SE0, CE0 and RE0. How do I modify the code so that I can do this measurement between CE0 and AIN2 (can I short CE0 and RE0 via software using the Switch Matrix?)

Hi simmy ,

Apologies for missing this thread. 

Do you still need help in resolving this issue? Akila and/or her team should be able to help you with this.

Thanks and regards,

Coco

Hi RAdante , I solved almost all of my issue but I would still like to know if there is a way to perform the Amperometric measurement via different pins from SE0, CE0 and RE0. (I also found out how to short CE0 and RE0 via software)

Hi,

Example amperometry code uses low power loop, where only either SE0 or RE0 can be used as current input pin.

If High speed loop (HSTIA) is used for this measurement, any of AINx pins, DE0, SE0, RE0 can be used as current input. 

Hi Akila, 
Thank you very much for the information. Could you briefly guide me on how should I change the code to perform an amperometry measurement using the High Speed Loop and consequently use different pins for the measurement? I am pretty much new into electronics and I basically deep dived into the AD5941. SO I got into some difficulties in adapting my code.
