10-Bit PWM using PIC16F1509

What does LED1 do while the signal goes out to LED2 and then LED3?

its unlit for 4mS of a 6mS drive signal period . pov makes the gap invisible at that rate


the pwm freq is 2kHz the isr switches the pwm drive @ 2mS intervals . for a pov objective its quite effective
its basically the same as how a 1/4 scan or a 1/8 scan led panel works, except its 1/3 scan

try it .

POV might make it invisible to eye, but cameras see all that flickering very well, and giving very poor recording. So unfortunately, that is not the way to go...

Plus, I would think having the led off 2/3 of the time would decrease the brightness quite a bit.

It is kinda multiplexed PWM signal I think.

it won't do for room lighting, it's still useful though
