Thread: High Frequency 16 bit PWM Dimming

Thanks a lot Kerry for the clarification. I guess this would mean however that a 1 dimming level would effectively be a PWM signal at a frequency of 24kHz/64 = 375 Hz (assuming the 10 bit PWM is 24 kHz) . The reason I am so concerned about the low level ie. 1 is that my application is LED dimming at a high frequency. Currently my LED at a PWM level of 1/1024 snaps on at too high a level. I would like it to come on lower at the first level of dimming. 375 Hz is too low a frequency for my application.
