Hi

I really appreciate any help with this.  I don't normally come to forums unless I've banged my head MANY times, and I'm at that point now where I could use some experienced help.  I'm brand new to VM, but it looks very promising.

I'm getting the following string of errors when trying to compile a version of a firmware called Marlin, which drives 3D printers, CNC machines, and some lasers.  There is one odd thing about it, and I'm not sure if it's responsible for this or not:  It comes as an Arduino project, but functions setup() and loop() are not in the .ino file...they exist in "MarlinMain.cpp".  However, I simply renamed them in MarlinMain.cpp, and inserted setup() and loop() functions in the .ino file that call the renamed ones in the .cpp file.

I'm using a motor driver board called an Azteeg X3 Pro, which is based around an Atmel Mega 2560.  I'm using Visual Studio 2015 Enterprise Update 1 with Win 10 (64) Home, and I'm both uploading and attempting to debug through the board's USB port (which on my machine is showing up as COM3).  I just downloaded the VM extension last night, and installed it immediately after installing Visual Studio.

Everything compiles fine under Release, but when I switch to Debug, I get an error message. 

The settings in Visual Micro that I set manually are: 

(Micro Debug) = Full
Remote Port = Serial2  <- (I saw on a tutorial video that the Mega 2560 uses this port. I have tried all available options for this: Serial, Serial1, Serial3, Serial4, Serial5, SerialUSB, even Console)
Remote Transport = SoftwareSerial
Upload Port = COM3
Remote Port = COM3

Here is the error I get when compiling:
Marlin.pde:In function 'void setup()
Marlin.ino:58:57: error: 'Serial2' was not declared in this scope
:void setup() { 
    debugger: The error shown above might be caused by invalid breakpoint syntax or the board is not yet supported for debugging (pls let us know!)
Error compiling project sources

Maybe I'm jumping the gun...the demo version of the plugin...does come with debug over USB functionality, doesn't it?

Thank you for any help!

Hi Tim

Thanks so much for your help.

I actually just read that and changed it, but now I'm getting a different string of errors.  They are:
Marlin.ino:In file included from
VM_DBG.h:170:2: error: 'HardwareSerial' does not name a type
:HardwareSerial *transport
VM_DBG.h:171:13: error: 'HardwareSerial' has not been declared
:void begin(HardwareSerial *theSerial)
VM_DBG.h:172:13: error: 'HardwareSerial' has not been declared
:void begin(HardwareSerial *theSerial, unsigned long baud)
VM_DBG.h:In member function 'void VisualMicroDebug::setVariable(T&, int, int)
VM_DBG.h:363:2: error: 'transport' was not declared in this scope
:transport->print("value=")

any idea what I'm doing wrong?

Thanks again

ps: If you do have to use the RemoteTransport = SoftwareSerial then you will not enter Serial2 into the RemotePort but instead enter the numbers of the RemoteRx and RemoteTx pins. These must be interrupt-able pins.

Visual Micro, you  can also try a forum search if you want.

OKay, maybe not as promising as I had hoped.  It only compiles if I choose the "build" option.  If I try to actually Debug, it stops after the first bunch of errors and doesn't proceed to try to build.   

Stuck again. 

Oh..my..GOSH.  You are correct.  I was fiddling with the debugger when I got it and created a generic "test" project, but didn't know it managed to get into my Marlin solution.

I deleted it, and now get the same errors, but at least the generic test project is gone.  Good eye!

Thanks for that tip.  I did try that combo of transport and port...still no joy.  Not sure what I'm doing/not doing wrong though.  Has anyone seen anything similar?
