uC is 89c52 standard, Crystal 24MHZ. Integration time is 20milli second and deintegration varies according to input signal. Sorry i have provision to accept upto to 24bits but 16 bits is sufficient.


I am using timer1 for dual slope 20 ms timer and also deintegration timer(data). Now timer1 increments every 0.5 uS. What i want is 15000 counts flicker free.
