I am doing a project in 8051 mc in which I have to generate atleast 5 PWM signals with varying period and duration. Is it possible? What is the logic to be used. Is anyone having the assembly code in 8051 or in C language for this? If so please send it to me at epey2p158@nitc.ac.in thanks in advance.
Nah. I'm sure Graham's software method would work perfectly reliably - just not very fast Ok, OK agreed; however if a scheme is concocted where one timer drives 5 PWM's - and try to go fast - I have no doubt that setup will stumble frequently. Erik
