I may desolder the 2 LSBs for each color channel. Only the VGA port is exposed to the header, which I’d use, but I think that them being connected to the VGA port via the R-2R makes that impossible as wired. Between the 16 bits + H + V for VGA, the 4x 7-seg displays and the SRAM, there are basically no ports left. Unfortunately, the dev board I bought was maxed out for IO. The porchie is what got me looking into FPGAs seriously. I’d totally get it if he had it available again. Maybe you could make a few of your boards up and throw them up on (After selling me one, lol). Plus It comes with a USB Blaster (which is basically just a PIC chip, but whatever) so I can get an even more stripped down board if I want. I figured I’d get a DE0 CV or something like that if I decided to keep going with FPGAs. It doesn’t have a lot of free pins due to the VGA port (16-bits is kinda more than you need for this kind of board!) and the LED display (which is another 8 or so pins - might mod it to be serial) but it seems to be a pretty good board for the price. It’s just a Cyclone IV with a VGA and PS2 port essentially. All the graphic STN displays I see are strictly monochrome with 4 or 8 bit interfaces with built in controllers. I haven’t seen a screen that supports 2 bits per pixel, or really any dot clock based display that isn’t a TFT. I kinda like the idea of keeping it portable, but just having a nicer screen.
