How can I mix colors in a rgb-led with only 2 PWM channels? (using atTiny13)?
I would like to mix colors in rgb-led. If done that before with the atmega8 and that worked great (because it hs a lot of PWM channels). Now i want to do the same with an Attiny13 because I only have about 20mm x 20mm (less that a square inch) place to fit the elecronics.
I can mix up 2 colors because the Attiny13 has 2 PWM channels but has someone a solution to add the 3th color. Keep also in mind that I only have 1kbytes of flash and that i need a big chunk of that for the effects.
Thanks for thinking along with me.
