Would anyone care to study or critique my very first BoostC program?
It's a novelty 12F683 program that does 32 PWM brightness levels per LED in a Charlieplexed matrix of 20 LEDs. The refresh rate is 62.5 Hz and each LED duty cycle can be varied from 0% to 20% in thirty two 0.625% (100 usec) steps.
The picture doesn't seem to show the smooth transitions I'm seeing. In fact you can hardly tell those are green LEDs.
