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.
Everything else responds. As in some programmes work and some don't. LCD text display doesn't work but LCD text rotation works but with shortened delay. If I set delay for LED's to be 1s, it becomes as fast as 2.3 seconds. Serial Communication perfectly working.
