Dear all, The number of PWM signals I want to use in my project is more than what LPC1768 generally has (6PWM + 3MCPWM). This is where I think I should use timers to generate PWM pulses. Since the frequency is so high, I cannot use timer interrupts to do my job. I tried to use external match registers, but it gives me a square signal (duty cycle cannot be changed.) the problem is that on each MATn.m, only one bit of EMR works. Is there any way I can generate PWM signals whith variable duty cycle (frequency is constant)using timer unit?
thanks in advance for helping
