The 8051 micro-controller(P89V51RD2FN) that I have been using is configured on a 11.0592 Mhz crystal. But the delays do not respond as per programmed. The programs are perfectly written and there is no issue in the code. Is my controller faulty? How to check that? Please provide some troubleshoot tips and tricks. Thank you very much.
how you handle delay by function or by timer ?
I do it by function. Using a nested loop.
try to do it with timer
no issue in the code
Of course you would say that, but it way more likely that you have got an issue with the code.
Maybe if you were as clever as me you would be able to say such a thing. But you are not me and therefore all you have done is make an obviously fictitious statement.
Almost certainly the source of your troubles!
