I am a researcher-maker-hacker focusing on Computer Graphics with a #retro, #fpga gaming twist. I am also very much into #3dprinting and #electronics.
These days I enjoy making #graphics hardware on fpga, using a language I developed, #Silice

And yes, the trace has been scratched to expose copper, cut in the center, and the resistor soldered onto it. I guess all these years watching @adriansdigitalbasement.com finally payed off 😎

2/3 The non-const wgpuBufferGetMapState will not error in any way, but give you a zeroed-out buffer 🤯 . Took me forever to find out.

This is as simple as it gets:
- clone the Silice repo
- run ./get_started_yowasp.sh
- go to projects/blinky
- make yowasp-ulx3s
- open localhost:8000
- program your board from a browser (locally)!
- clone the Silice repo
- run ./get_started_yowasp.sh
- go to projects/blinky

14/ Using the design is quite simple, after loading data in the pmod, I select my design, change the clock frequency (currently runs at 17MHz max, I'll have to investigate, more on this later!), and hit reset.

13/ urish already made a great tool just for that!

I just modified it to initialize Quad-SPI transfer after uploading a file, as my design is very lazy and assumes the PSRAM pmod is already fully loaded and ready to go!

12/ How do I put data in memory in the first place? #TinyTapeout is an amazing project with amazing tool, and the demo board has a RP2040 onboard with micropython on it. So you can use that to initialize ('flash') data in the PSRAM pmod before statrting your design.

11/ I store all of that in memory (in the PSRAM pmod): for each step, 1/z and x,y offsets along the ray. The terrain texture (height and color) is also fetched from memory.

10/ However, I pre-compute many things in RAM to reduce the design size. The algorithm draws the screen column by column, left to right, and then steps along the ray in depth. Each step it draws small segments if they are visible. This requires 1/z, as well as stepping in x,y along the ray.
