I’ve created a GitHub repository with example projects for testing my VS Code db65xx debugging extension. If you already have cc65 installed, you can try out these examples with a few keystrokes.
Here are a few screenshots:
Basic terminal I/O
Example of integrated terminal I/O. Prints “Hello world!” to the terminal and accepts keyboard input into a 256-character circular input buffer.
Interrupt driven I/O
Example of interrupt driven I/O. Uses the 65C22 shift register for keyboard input and the 65C51 for terminal output and file input.
32-bit Floating Point Package Test
Example of using the 32-bit floating point package.
