RPi B+ and 2 have 40pin (26 usable GPIO).
6bpp (666) is using 6 pins for every color (RGB) + 2 pins for horizontal and vertical sync, totaling 20 pins used.
8bpp (888) will use 8 pins for every color, totaling 26 pins.
What value resistors will be needed for 7th and 8th pins? Starting at 16k Ohms, every pin half of previous, so i guess 7th will be 250 Ohm and 8th 125 Ohm. Or not?
Is that possible? I think everybody would like full 24 bit color depth on their analog output (me too).
Documentation say's that PCB is designed for 666, so just add another 6 lanes.
Then just use "dpi_output_format=7" and it should work
I'm mainly asking about needed resistors and connecting to DE15.
If its possible, i will try to make it and post final "product" here.
