This is an example of the tty-based simulator running DBug-12.
The graphical integrated development environment.
To try this example with ide6812, build the software and load leds-buttons.asm into the editor tool and leds-buttons.conf into the peripheral tool. Hit the compile button (the C inside a circle) on the editor. Hit the download button (the lightning bolt) on the editor and type "g 800" in the console window. Click mouse-button-1 in the gray bar to the left of the code in the editor window to activate a breakpoint. Press and release the "Increment" or "Decrement" buttons to make the lights change.
