Sir, I am using 89c4051 to convert digital to analog. pin 1.0 and 1.1 are used, but I am confused how to us? please help me I don't know anything.
The problem got resolved, now its working. I don't know exactly where the problem was.
Then the problem has not been resolved. It's just gone away for now. But if you don't know what the problem was, then it cannot possibly have been resolved.
