STM32L562 DAC output on PA3 via OPAMP1 follower breaks when using PA4 as GPIO output
I can successfully output an analog voltage on PA3 from DAC1 Channel 1 via OPAMP1 in follower mode. If I try to use PA4 as a GPIO output the analog voltage on PA3 disappears. Is this a known issue with this chip? Are there any workarounds?The referen...
