Can bus shield and Arduino Uno pins

[Jacket_Chen]

@pauldevissers

thank you jacket, I will do this tomorrow:

and will try it out without (1) library-modification and (2) worrying about Arduino-Uno using pin 9 for RESET. (OK?)

p.s. for me it is not necessary to remove an existing solder connection

If using digital 9 as CS pin, you need modify some codes:

#define SPICS 10

You need modify it in mcp_can_dfs.h , and you don’t worry about any other problems.
