	Subject says most of it. Uno, VS2012Pro. If I build Debug and then do a Start Debugging, it'll hit what looks like a breakpoint on loop(). But I can't single step, and if I set a breakpoint a couple of lines into loop(), it does not hit them. If I hit go, hits that same breakpoint again. I've done the 'c' in the serial console, no different. In short, I'm not getting a lot of debugging done! I searched as best I could, but this question is apparently more basic than most! Any tips or a pointer to a relative thread or FAQ entry (or terms to search for) would be appreciated. Thanks! Dave

	Hi Dave, Sorry to say that Arduino does not have real debugging. the Visual Micro debugger is a software/usb debugger that injects the breakpoints into a temp code during compile. So you have to re-compile and upload to add breakpoints. It is also not possible for it to step all code lines, only to ones with breakpoints. You can only step from breakpoint to breakpoint. It's also worth viewing the debugger breakpoint docs to see that breakpoints are injected at the end of a code line or, for example, inside an "if" if placed on a conditional code line. "If" conditions without braces are handled. The debugger must be viewed only as an alternative to using Serial.println() statements in your code to debug along with some additional break/update capabilities.
