Sharing my project which I hope to submit after resolving the open lane flow issues + DRC fixes. Animated GIF in README is from the demo software. Parts of it might also be useful to others with video projects: the

rgbs_logger

module + PNG script + Makefile target runs Caravel in iverilog, then generates a PNG from captured RGBHV outputs: https://github.com/dan-rodrigues/caravel/tree/vdp-lite

looks cool. I had a quick look through. No frame buffer? Just flip-flop memory for the sprites?

yeah there's a pair of FF line buffers here. If I go beyond 8 or 9 bits for the address the tools don't seem to like it, for randomly placed FFs I guess that makes sense: https://github.com/dan-rodrigues/caravel/blob/vdp-lite/vdp/vdp_sprite_core.v#L251

cool

Where are the sprite from ? Small memory ?

The character set is baked into ROM: https://github.com/dan-rodrigues/caravel/blob/vdp-lite/verilog/rtl/vdp_lite_user_proj.v#L337 I thought about a few openRAM blocks to make it configurable but was hesitant about it...maybe next time around it, if things go well this time
