I have tried everything... I can not get my wiz812mj to work with my arduino mega.
I attempted this hardware/software hack but the SPI file from 0015 is very different then that of arduino 1.5 IDE and the older version of arduino 0015 will not work on my windows 7 computer.

Please help... ! Theres got to be a way to get this working in the current version of Arduino 1.5 IDE or maybe im doing something wrong?
Where do you have the version 1.5 of the IDE from? The newest I can find is 1.0.1.
The hardware hack described on this page is getting a shield which is not Mega compatible to work with a Mega. If you rerouted the hardware pins you don't have to patch anything. I would just not reroute the CS pin (10) as usually pin 10 is used on the Mega too (in the software). If you've done so you don't have to patch the software as the current IDE has support for the Mega and knows the different pin layout of the SPI.
