Dear Sir, I am having a problem with at89s52 on power up. I am doing a project which demands serial communication via serial port. I have gone through one of the threads here, where you had advised one Mr.Bhagirath to use 3-pin rest(MX810). So, I get it that the problem MAY BE in reset button. But, I would also like to share with you the fact that earlier I did not have any arrangement for reset, then it never misbehaved. So, what are the other areas from where this anomaly is rising?
Can you post the code you are running? It might help demonstrate the issue. For instance, if you have an extended delay that you assumed was in ms but is actually in seconds, it's possible we could randomly guess this but it would save a lot of time to see the code you are working with. Please remember to use the "pre" tags when posting code (should be described above the text box when posting a reply).
