    Control/Dimming LED frequency: does it affect lifespan?

    Control/Dimming LED frequency: does it affect lifespan?

    Sure, but might be more than a sentence or two :pIncreasing the PWM frequency requires either increasing the frequency of the clock that drives the PWM counter or reducing the resolution of the counter. Since the maximum clock frequency is limited by the hardware generating the PWM signal...
