just checking i am on the right path, i need to control a number of small fans with pwm, so far the frequency looks like being around the 3kHz range. i am thinking software pwm with two timers, i dont need huge resolution probaly 10 settings between 70% and 100% should do it, am i correct in thinking i need to set first timer as the frequency, so as it rolls over i turn all fans on the second acts as duty cycle so i set it for a period that equals 1oth of the main clock and switch off any fans that match the number of times the timer has rolled over?
hmmm i think i have confused it all there but i kind of know what i mean
