My bad, I meant 300 hz, not mhz, for the 2N2222. Got so used to typing "mhz" that I didn't notice. My bad.
I already pointed to the reference. "\note The default of 8192 means the PWM frequency is 976.5625Hz */".
EDIT: I'd still like to try using transistors. Inversion makes sense since I have the "BLANK" line going through it. Is there a magical way to fix inversion? Do I just hang the chip up-side down? (Canned laughter here, please.)
