Sorry Guys. Yes. It is a AT89C2051.
The output of the op amp is connected to P1.2 I wrote few lines of code to turn another pin (P3.7 output) to 1 if the P1.2 (input) goes to 1 but I do not read the change of status. If I remove the connection I see the op amp changing status to +5 so the circuit works. As soon as I try to read the LM358 output through the P1.2 (therefore connected to it) the voltage goes to about 1.2V and I believe that is why the 2051 doesn't read it... |
