Isle 🏝️ is my new #FPGA project.
Isle is a simple, modern computer — an open design that encourages tinkering, experimentation, and doing your own thing. I hope to inspire you to come on a journey with me and build your own computer. projectf.io/isle/fpga-co...

If you're writing assembler, I heartily recommend Compiler Explorer. I wrote about this from a RISC-V perspective a while back. #asm #riscv

I finally got around to doing another Surfer release, so now we're on v0.4.0 🎉
My personal highlights are the new web assembly based translator system, and the improvements to our waveform control protocol, and you can read the full change log at gitlab.com/surfer-proje...

I realise I've been a little quiet on the 🏝️ Isle #FPGA computer over the last month, but I've been beavering🦫 away on the 2D drawing engine, including 8 new Verilog modules, docs, tests, and a blog post. You can see a screenshot from the draft blog post below. More news soon…

I meant to type the word "hardware"; I typed the word "garden" instead. It would be nice to think this reflected a deeper truth, but it's probably my mind telling me to stop looking at Verilog. 🤔

Over the weekend I released the next part of Isle #FPGA Computer covering bitmap graphics.

I've added more docs and tests, but I'm still finding the right approach to the Isle blog and working on diagrams.

I'm getting to grips with more cocotb tests for Isle #FPGA computer. This new test verifies pixel output end-to-end: address_calc > vram > clut > display. We're not letting any latency issues sneak in. Will be part of chapter 2: bitmaps.

For some time @securelyfitz.bsky.social and I have been working on a new hardware security tool. A tiny m.2 WiFi module sized FPGA board allowing the access to the PCIe interface. You can sign up for updates for when the campaign launches, some time next year. #EpicErebus #fpga

I’m sad that smaller laptops seem to be a thing of the past. Where are the 10”-12” laptops for writers, travellers, and techies on the move? I want a proper keyboard for writing on, developing on, and SSH. 🤔

Icepi Zero looks like an interesting open-source ECP5 #FPGA dev board. It’s got a decent spec in a small form factor. The only obvious omission is audio out. The big question is, how much will it cost? www.crowdsupply.com/icy-electron...
