I conect the boad arduino mega 2560 only with usb.
I open the program: ( Arduino erg 1.0.2)
I open an example. I do compile. Is ok.
I do upload.
And now its write: Done uploading. OK . (It can see the board in com 14. OK)
But : with red letters writes:avrdude. exe:cant find programmer id wiring valid programmers are: .......
On TOOLS: I chooce: Programmer: Arduino as isp . (is it ok?)
No that's wrong. I use "AVRISP mkII" as programmer (which was the default when I installed).
As I have understood "Arduino as ISP" is used when you want to use your connected arduino to upload onto anther
arduino (one perhaps custom built without USB).
So select that, change to "Arduino MEGA 2560 or ADK" under Tools->Board. And if it doesn't work, verify that the COM port used under Tools->Serial Port is actually the one used by your arduino, which you can find in device manager if your using windows.
