Hi, I am trying to use Processor Expert Software configure the LED on KL25Z to use PWM at 500Hz with a fixed duty-cycle of 20%.

How can I set frequency and duty-cycle in this case? And am I be able to see a dim light? Or 100% brightness?

Hi Lei,

I hope the thread Hi, I am trying to use Processor Expert Software configure the LED on KL25Z to use PWM at 500Hz with... solves your question here. As far as dimming goes, yes varying the duty cycle would show you a dimming effect with maximum intensity at 100% duty and minimum intensity at 0% duty. Hope this helps.
