[size=85]I am also having issues changing the CS pin for the CAN Shield. I am using a 2.8" TFT, this device uses pins 10 AND 9 on the Arduino Uno so I was looking use a different pin (7 or 6). Although I’m looking to use those different pins I was still unable to get the shield to work when using pin 9 (by soldering the CS pin to pin 9, disconnecting pin 10, and changing the SPICS 10 to SPICS 9 in the mpc_can_dfs.
Has anyone been able to change the CS pin yet? Is there something else in the libraries or source code that needs to be set to allow this to work?[/size]
Used the new library provided by Cory, it works! Missed that part the first time but thanks for your help. 
Thanks,
Sean
