#157899 - Have u checked Pin voltage Responding to: ???'s previous message |
Hi Alex,
Just a few hints, You have seen op-amp output is 5V without connection with mcu p1.2. 1)Have you checked P1.2 logic state when it is open (is it 0 or 1) 2) What is supply to op-amp? 3) Is there any pullup connected to op-amp output? 4) Is there any other circuitary connected at P1.2 or op-amp output? Regards, Mahesh |
