I've assembled the prototype now, using a 16F716 I have some of these around from a few years ago.
Circuit is a matrix, common Anodes which are driven by PORTB, and cathodes for each color also connected , sink is done with 2n7002 mosfets.
It is programable fully, compared to these CD4017 circuit kits, which are surprisingly popular but a bit boring after some time.
Subject of examination are how much voltage does this display need,and how many bits resolution i get for each component R,G,B (using a 5 MHz resonator, this PIC needs less than 1mA for itself).
And of course, how does it actually looks like?
