Trying to emulate an incandescent light dimmer with a LED. Using PWM module of a 16F684 (though that is not set in stone)
Problem is for PWM "on" ratios between 25% and 100% the brightness change is not that much but the last 25 % is where it all
happens, the last few steps being rather clunky. It's a bit like using a linear taper pot as a volume control where a log pot
is what is really needed). Need a slow even fade (over a set time, in my case a minute). Working in MPASM (no flash C compiler).
Anyone cracked this nut?.
Cheers
