Re: Accessing GSR data using C code

Coen: Thanks for the help. I used some resistors and the process as you clarified it (also skipping my step 4) and got values that look good and matched data collected via Actiview, so I think we are set. Just to confirm though, my step 4 (the downsampling) is incorrect (either entirely or just beca...

Re: Accessing GSR data using C code

Coen: Thanks for the response. 1) Assuming some of the exact numbers (scaling and filtering) may not be essential, would it be possible to just get the theoretical goal of how to go from the two raw voltages values to a final GSR/Impedance value? 2) Failing that, I had a look at the Labview code wit...

Accessing GSR data using C code

Hi, I am having trouble storing GSR data when it is directly accessed using some C code, but no trouble storing the EEG data, and no trouble with the external data (EX1-EX8). There is more detail below, but my core questions are: 1) Is the GSR data treated differently than the external analog channe...
