Hi Mahesh,
Q1)Have you checked P1.2 logic state when it is open(is it 0 or 1) A1) I set P1.2 to 0 at the run (via software) Q2) What is supply to op-amp? A2)6V Q3) Is there any pullup connected to op-amp output? A3) Yes, 10K. I also tried with 4.7K Q4) Is there any other circuitary connected at P1.2 or op-amp output? A4) No. The op amp goes straight to P1.2. nothing else connected excepot the pull up res 10K. I even tried a new LM358 just in case...no luck! Any idea? Thanks Alex |
