Let´s throw the code together. ecrutz has the real pinball dmd interface running , i have
the pinmame usb interface running.
Currently have a 12bit palette (4096colors) to chose the 16colors from I use to map
to the 16 shades of a Stern ROM or the 4 colors for the 4 shades of a WPC ROM.
I have a code sample here with 33bit palette which may be adapted to my code
but I think 4096 is enough by now. Sometimes it is already hard to seperate the 16 shades
of one color.
A video of my first colormapping implementation and more info can be found in the vpuniverse forum
(I´m not allowed to post links here due to the fact that I´m new to the forum)
I´m plannig to design a pcb with a connector for a classic DMDs like Stern, Vishay etc. driven by USB and Pinmame (like PINDMD2),
a connector for the china 2.5pitch RGB panels driven by USB and a classic pinball interface to drive the china panel. All with
color mapping to either a fixed palette or dynamic palettes with in-frame coding like SmartDMD.
I will use two RGX panels side by side
Search for "RGX-p3mm-Indoor-SMD2121-rgb-led-display-module-192mm-x-96mm-64-32-pixle-HD-Video" with the brackets on google.
They cost 21.50$ each plus shipping.
