Thanks Acetronics, i'll try that out.
But sayzer, i want to use a PIC16C54A. It does not have TMR0 interrupt.
I have to mux 4 displays, check 4 buttons and keep accurate time.
How can i keep track of time without the interrupt???
Is there a way to keep time accurately without using hardware interrupts and do the rest of the stuff in PBP???
I have made a clock using a F84 and TMR0 interrupt...
Now i want to do the same thing without the TMR0 interrupt in PBP...
