Debugging support is provided for Assembly, SDCC and Microbe, when they are open as a text document. From here, stepping is controlled via the menu. There are two methods of starting the debugger.
If the PIC program is already running in a circuit, then double-clicking on the PIC component will open up the program. For assembly PIC programs, the debugger for that text document will be linked into the PIC component. In this case, the debug menu cannot stop the PIC program - as this is owned by the PIC component.
If the assembly file is already opened, then the debugger can be run via the menu. After compiling the program, the debugger will be ready, with the PIC program paused at the first instruction. Note that when debugging high level languages, the current execution point will not be shown if there is no line that corresponds to the first assembly instruction to be executed. In this case, clicking will bring the execution point to the first line in the program.
