I have an FPGA and I've loaded up a sample that outputs a VGA signal[0] but the output is only based on hardwired patterns, not driving by a frame buffer or CPU. I'm not sure where to go next in order to use the memory chip on the dev board (I have the Digilent Arty [1] as well as a MiSTer FPGA setup) or have some sort of frame buffer which I can use with a CPU that is also running in the FPGA. I'm 90% through building Ben Eater's 8 bit cpu on breadboards (just have to add the control logic) and I did the 65C02 project of his just before that, so I'm definitely in the market for learning where to go next with it. My dream is to have a computer that I have completely design control over :) [0] https://digilent.com/reference/learn/programmable-logic/tutorials/arty-pmod-vga-demo/start https://digilent.com/reference/learn/programmable-logic/tuto... specifically [1] https://digilent.com/reference/programmable-logic/arty/reference-manual https://digilent.com/reference/programmable-logic/arty/refer...
