Question
Op Amp to ADC 'spair' pins not available for other use??
STM32F302RBT...
I want to use OpAmp1 in PGA Connected mode feeding ADC1 IN3. According to CubeMX the OpAmp pins VINP, OPAMP_VOUT and VINM are all 'Used' even though VOUT is internally connected to the ADC and VINM is not being used.
If in the cube I change the setting of VINM to GPIO it shows that the opamp to adc connection is no longer available.
Is this just an error in CubeMX or are those pins no longer available for other use?
