TLC5940 and ATtiny84 - working!

[fungus]

8 MHz, 4096 steps, that comes out to 512 microseconds. I wonder how well blink-without-delay would work? Is it really that important for BLANK to be fired accurately?

@fungus, what did you build with an ATtiny84 and a TLC5940? How accurate does BLANK need to be?

All LEDs turn off after 4096 pulses on GSCLK (when they go past their PWM value). The BLANK signal turns them on again and resets the internal counter for a new PWM cycle. It doesn't have to be perfect.
