Hello AD Team,
I have purchased AD5940 EVAL ELCZ board
I want to perform EIS measurement for a 3 electrode system
Working electrode - Gold
Counter electrode - Platinum
Reference electrode- Ag/AgCl (0.21 V vs Standard Hydrogen Electrode)
Calibration settings :
frequency range: 1KHz to 10Hz
Bias voltage: 300mV vs Ag/AgCl reference electrode
In the AD5940_examples code for impedance measurement , the method used was Sense electrode connected to AINx pins which was a 2 electrode system (WE :AINx and CE: CE0)
How do I modify this code to accommodate a 3 electrode system as given above ? What should be the switch matrix configuration ?
Kindly guide me through the process
