Hey does anyone have any advice on choosing the frequency of PWM driving some RGB LEDs?
Originally I chose 200Hz because I read it was a good frequency to choose because it was the smallest that would likely not appear as pulses to viewers of any age.
Complications with noise led me to increasing it all the way to 20kHz. Now we have worked the noise issue out of the system. Idk if I should lower it again or not. At 20kHz I have a resolution of 400 values per channel which I believe is more than enough. What else should I be considering when choosing a frequency?
