Hello,
I am using opamp to amplify the ouput voltage from piezoelectric. Output from opamp will be the input for ADC. But I have an error to connect external resistor.
I don't know what i did wrong. Can you help me, please?
Thank you for your help,
Tita

You have to use the dedicated pins connected to the OpAmp. You can refer to the Design Wide Resources > Analog schematic view.
OA1:
Negative: P9[4]
Positive: P9[5]
Output: P9[3]
OA0:
Negative: P9[1]
Positive: P9[0
Output: P9[2]
