Accessing the openFPGA BRIDGE part 2 👾

Another full day of debugging and understanding more and more about the ‘Right Way™’ to do things in #Verilog and…boom! 💥

My gfx chip is now working correctly based on the 4 registers it exposes. I still don't have a working CPU yet but this is using a little FSM to drive the chip.

This is so much fun…

👾 Just posted pf-dev-tools v1.0.6:

✅ Fixed a bug in argument parsing for pf clone.
✅ pf install and pf eject now take full paths for volumes.
✅ Added support for PF_CORE_TEMPLATE_REPO_FOLDER to use local core template directory.
✅ Improved some documentation in README.

✅ Added better user feedback when docker image needs downloading.
✅ Renamed Environment to SConsEnvironment.
✅ Added an automatic check for when updates are available.
✅ Improved the way some error messages are displayed.

Introducing pf-dev-tools 🎉

This is the toolchain I put together to build and package my fantasy console core on the pocket. It's entirely Python-based thanks to SCons which is built in.

Super simple Makefiles. One line core building/packaging/installing. Did I mention Python?

Anyway, it's also used in the sample code for the openFPGA tutorials.

Here we go… first bit of ‘real’ work done on the graphics chip. It takes two 16-bit values as input and displays them as a debug overlay on the screen.

This will be super useful for debugging the core…

👾 New blog post: Stars and Sprites 👾

I think I now have enough #Verilog knowledge to get started on the real graphics chip for the pfx-1 console.

Wish me luck!

Hardware sprites, ultra-mini Copper, LFSR star field… I‘ve learned a lot so far. Next stop, reading data over the APE and interfacing with a couple of different types of RAM.

Oh working over different clock domains too!!
