I am an amateur in mP. I am trying to use my PC to connect to AT89C51 but i am not succesful. Could all of you Please share your experience in this field?
There are 3 possibilities:
1. Your software isn't working;
2. Your hardware isn't working;
3. Neither your software nor your hardware is working.
With no information to go on, it is impossible to say anything further!
What steps have you taken so far to isolate the problem?
Dear Andrew Neil,
Do you have email box? I will send the schematic, code and PC software to you. Now, I am very confused. I don;t know how to solve this problem.
IF you are writing your own PC software that, of course, adds another possibility:
4. Your PC software is not working.
You have far too many unknowns!
Start by checking your code in the Simulator.
Then run it in your target, but use Hypoterminal or similar on the PC.
Once this is all working, try it with your own PC app.
