for a small data, i used to test my code in the 8051-kit.
I used timer-0 and from code memmory i fetched the pre-loaded values to TL0 & THO.
Then i have set the Port 1 and Port 2 pins in some patern. the timer starts and runs well.......
But it generate the pulses with same time interval, ie., at constant frequency(say,6.66Khz).
I cheched the TL0,TH0 locations they are loaded correctly. But for all the delay counts, i get the pulses at same interval only, no variations.
Please help me for this problem.
