HELLO
I am new on uzebox and not ready to go so excuse if i tell wrongs things
does 12 or 11 bit color possible IF A SERIAL REGISTER is ADDEED ON THE SPI AND IS USED WITH SPI
I MEAN
DOES THE CPU AS TIME TO READ A COLOR AND SEND IT TO PORTX AND SEN SOME BIT VIA SPI
THE PORTX AS A TIME TO REACT DOES DURING THIS TIME A SERIAL REGISTER CAN BE FILL ONTO 4 BIT WITH USING SPI
WHAT DO YOU THINK ABOUT
THANK YOU
DOES 12 BIT COLOR POSSIBLE ?
Re: DOES 12 BIT COLOR POSSIBLE ?
Probably a way to do it, but why. Put some ram in front of a 12 bit DAC, and you could have fast 256 colors out of 4096 changeable per scanline. Rewrite the palette during hsync. Serial shift registers with multiple sources, ports, pins is going to be really low resolution otherwise.

WELL
I WAS THINKING OF ADDING 4 BIT SHIFT REGISTER for made 8 bit portc and 4 bit spi
in another topic i explain that the port b of atmega644 is double speed than portc
may be it is better to user portb for made 16bit color

A lot of things are possible with more hardware and I guess actually you could do it with shift registers. Ultimately I think less people would build that, but if it is interesting to you why not.
