I setup a basic PRiSM block connected to the onboard LED on the development kit. I set my target Fout to 500 Hz and I see a lot of flicker. The app note about PRiSM states that "FOUT ~= 300 Hz to have flicker free LED dimming" I can't seem to get it flicker free be 2 kHz. I have validated Fout with my oscope and it does show 500 Hz.
My setting are as follows:
Fin = 2 kHz
Pulse Density = 50%
Resolution = 8 bit
Fin calculation
Fout = Fin / 4 @ 50% pulse density
500 Hz = 2 kHz / 4
