Hi,

This is covered in the docs but it's not a major topic so probably not so clear.

You can use the debugger in any code that can use commands such as Serial.println()

You probably need to switch off the ThottleEnabled project property and ensure that you do not use the breakpoint hit counter. This should ensure that the debugger never uses the delay() command which is probably the problem.

Hope this helps.

tip: Setting the breakpoint "continue execution" will give trace instead of break, which will have less effect on timings
