uv4 debug - first impression very good

So I forgot about using Flash Magic altogether, and disconnected the Somy board from the PC USB, and used uv4's simulation mode debugging.

My first impression is that this uv4 debug is very user friendly and also very powerful.  Comparing to the Raspberry Pi Python development environment, I would think this uv4 is at least twice more time efficient.

It took me minutes to find a couple of careless bugs in my blinky program.  I used the keyboard function key F10 to step through the blinky program and happily see the GPIO data and directions registers contents change in real time.  I also used F5 to run the program and it is very nice to see the tick in the DATA8 box repeated appears and disappears by the delay time.

Next step is to try the input function.  I guess in simulation mode, I can simulate the pressing of the key by ticking the related little box.  That is indeed very nice.
