Try build https://github.com/MarlinFirmware/Marlin when full debugger enabled. I use VS 2015 Community.

Code
Select All

An example debugger breakpoint has been created.
To switch the demo breakpoint off, deselect Visual Micro>Tutorial Mode.

Hi,

Marlin redefines the Arduino serial ports which, for the 2560, normally uses the HardwareSerial.

I haven't had any info from Marlin users yet that explain the Serial commands that could be used for either of the Serial ports on the 2560. With that info we might be able to hook up debug.

In the meantime you can use the SoftwareSerial option if you have an FTDI>Usb connection?

More about SoftwareSerial here http://www.visualmicro.com/page/User-Guide.aspx?doc=Debugging-With-Different-Por...
