Shrike Projects

Things people have built with Shrike.

This is the showcase repo for the Shrike FPGA boards (Renesas SLG47910 ForgeFPGA + RP2040 / RP2350 / ESP32-S3): complete applications, demos, and experiments built by the community.

Looking to learn FPGAs instead? Start with the curated teaching examples in the main repo.

This repo is where you go once you want to see what the board can really do , and to add what you built.

FPGA ✅ = uses the ForgeFPGA fabric. - = firmware-only. Both are welcome here: if it runs on a Shrike board, it belongs.

100 Days of Shrike

Drik Paul has created a very comprehensive repo for 100 days of shrike project and he is actively workign on it. Check it out here.

    └── media/                  images < 200 KB , videos as links, never files

Same per-project conventions as the main repo's examples, plus host/ and hardware/ since real projects tend to need them.

Running a project

Each project's README is self-contained, but the common flow is:

1. Flash the prebuilt bitstream from bitstream/ using ShrikeFlash (skip for firmware-only projects).
2. Load the firmware from firmware/ for your board variant (MicroPython via mpremote, or Arduino IDE , see the getting-started guide).
3. If there's a host/ folder, run the PC-side tool per the project README.

Board compatibility is listed per project , bitstreams are identical across Shrike variants; firmware may be MCU-specific (RP2040 vs RP2350 vs ESP32-S3).

Contributing your project

Built something on a Shrike? We want it here , polished or not.

1. Check it's a project, not a teaching example , see the classification criteria. (Rule of thumb: examples teach one concept; projects show what the board can do. When unsure, it goes here.)
2. Copy the layout above (or an existing project), name your folder in lowercase_snake_case, and fill in a README that lets a stranger reproduce your build.
3. Keep the repo light: compress images to < 200 KB; for video, drag the file into a GitHub comment/README on the web editor and link the generated user-attachments URL instead of committing it.
4. Open a PR. Review here checks that it works and is documented , not that it's minimal. Creative scope is unlimited.
5. Complete Contribution guide is available here Contribution Guide.

Your commits keep your name , that's the whole point of this repo.
