Split Mega 2560 and Mega ADK into two different boards

[Lauszus]

I suggest splitting Mega 2560 and Mega ADK into two different board entries, so "build.board" will have two different values instead of always being:

Arduino/hardware/arduino/avr/boards.txt

Line 182 in 429b516

mega2560.build.board=AVR_MEGA2560

.

This will allow the USB Host Shield library automatically detect if an Arduino ADK is used, so the library can be compiled for it.
Right now the user will have to enable it manually by editing the source code - see: https://github.com/felis/USB_Host_Shield_2.0/blob/77538f5d2d0654155c8569298f8441b1175b19cd/settings.h#L32.

Please tell me if you want me to open up a pull request, then I will be happy to do so.

Yes, if you can make a pull request it would be great.

I don't know why the two boards was combined in that way, but I guess we can safely split them.

I'm also thinking if its worth combining Mega with Mega2560?

[Lauszus]

Okay I will combine them as well :)

Sorry but are these lines:

Arduino/hardware/arduino/avr/boards.txt

Line 164 in 429b516

mega2560.cpu=2560 or ADK

and

Arduino/hardware/arduino/avr/boards.txt

Line 189 in 429b516

mega.cpu=ATmega1280

not an error or have i misunderstood something?

[Lauszus]

Also I really don't think the text in this readme is true anymore: https://github.com/arduino/Arduino/tree/ide-1.5.x/libraries/USBHost/extras. Would it be okay if I removed it?

Also I don't understand why there is not mention of the USB Host Shield library here: https://github.com/felis/USB_Host_Shield_2.0 in the Arduino ADK documentation: http://arduino.cc/en/Main/ArduinoBoardADK?

[Lauszus]

Do you want me to call the menu entry "Arduino Mega or Mega 2560" or just "Arduino Mega"?

[Lauszus]

Also please confirm that these VID and PID values are for Mega2560:

Arduino/hardware/arduino/avr/boards.txt

Lines 160 to 161 in 429b516

	mega2560.vid.0=0x2341
	mega2560.pid.0=0x0044

and these are for the ADK:

Arduino/hardware/arduino/avr/boards.txt

Lines 162 to 163 in 429b516

	mega2560.vid.1=0x2341
	mega2560.pid.1=0x003f

.
I haven't got a regular Mega2560, so I can not check the VID and PID for it.

[cmaglie]

wow, ok let me check one at a time:

• the entries mega.cpu=ATmega1280 and mega2560.cpu=2560 or ADK are typos coming from the menu refactoring, you should safely remove them.
• also the https://github.com/arduino/Arduino/tree/ide-1.5.x/libraries/USBHost/extras is wrong, please remove it!
• Call it Arduino Mega, inside the Processor menu place the entries ATmega2560 (Mega 2560) and ATmega1280
• About the documentation I don't know the details of the Mega ADK, I'll ask to add a link to the host lib in the doc.

An handy list of VID/PID is here:

Okay thanks.
