Hello,

I'm using Visual Micro with a Mega that has a USB<->Serial AVRISP mkII programmer, but I can't program it when I use Visual Micro. I think I've traced the problem to the avrdude command. The avrdude command line that Visual Micro uses is:

D:\arduino-1.0.5\hardware\tools\avr\bin\avrdude -C"D:\arduino-1.0.5\hardware/tools/avr/etc/avrdude.conf" -v -v -v -v -patmega2560 -cstk500v2 -Pusb 0\Marlin.hex":i 

compared to the avrdude command the Arduino IDE uses:

D:\arduino-1.0.5-enhanced\hardware/tools/avr/bin/avrdude -CD:\arduino-1.0.5-enhanced\hardware/tools/avr/etc/avrdude.conf -v -v -v -v -patmega2560 -cstk500v2 -P\\.\COM5 -b115200 -D -V in.cpp.hex:i 

The key difference looks like the port configuration:

Visual Micro:
  -Pusb
Arduino IDE:
  -P\\.\COM5 -b115200 -D -V
 

I've tried it with the 1.0.5 stock, 1.0.5 enhanced, and 1.6 IDEs but it has not made a difference.

Is there any way to add a AVRISP mkII programmer that uses the configured COM port instead? I've looked at the documentation and programmers.txt files located under the %PROGRAMFILES%\Visual Micro folder and I don't see anything obvious. Am I missing something?

Thanks,
Jamie

Ah, I see where I went wrong. I wasn't using Upload using Programmer in the Arduino IDE - I was using the regular Upload function, which uploads via the COM port as expected. Thanks for pointing that out. I turned off "Upload using programmer" in Visual Micro and it uploaded correctly from within Visual Studio.

The same programmer was selected (AVRISP mkII) but I had Upload using programmer turned on. I think I misread that in the documentation.

Thanks for a great product!
