In my last post I showed that you could run cc65 compiled C-based code on the 65816. The main limitation was that the C-based segments had to be located in Bank 0 (and of course that the standard C-library functions were running with 8-bit registers and none of the 65816 added instructions or address modes). …

I’ve been wondering for a while if I could run C-based code on the 65816 using the cc65 toolset. Browsing through the cc65 documentation and C libraries it’s pretty clear that the 65816 isn’t specifically supported. In fact, the C libraries are primarily targeted towards the 6502 with just modest support for the 65C02. The …
Try out the completed N-Queens project discussed in this post You may have noticed from my last few posts that I’ve been adding support for the C programming language to my db65xx debugging extension for VS Code. When I first started with cc65, the added complexities needed to program in C kept me firmly in …

I’ve added the capability to view local variables in C functions to the db65xx VS Code extension. I plan to write a bit more about this, but for now, here are a few screenshots. You can try it out with my Sieve of Eratosthenes project.
12/17/2022 Update: db65xx now handles normal debug stepping within C files. I successfully ran my C-based Hello World example project in my VS Code db65xx Debugging Extension but needed a more rigorous test of C-based debugging. I often go to Rosetta Code to look for code samples to test on my various builds and find …
I’ve added some support for C-based debugging in the VS Code db65xx Debugging Extension. Try it and other example projects out in my db65xx projects repository.
