SPICS to MCPCS MODE_NORMAL to mcpMode Support to change operational mode of MCP2515 (sleep, listen only, etc) Support to enable No Mask/Filter, Standard IDs Only, Extended IDs Only, or Both. Support for 20MHz (Need to add constants to [..]dfs.h file!)

Should work now...
This sketch demos the ability for this library to support more than one CAN interface on a single Arduino.
Depreciated 'mcp2515_start_transmit' function call as it's sole purpose was to call another function and return. Per http://forum.arduino.cc/index.php?topic=152145.msg1654634#msg1654634 After review of the code, this appears to be correct but I need to test this before I apply it to the master branch.
Removed depreciated private function mcp2515_start_transmit
Trying to make an example sketch to demo masks and filters found and some errors... There appears to be a further issue that I have not resolved, standard ID filtering doesn't work for me at the moment. I have been successful with extended ID filtering before attempting to make the demo. I think the issue lies within 'mcp2515_write_id.'
Added function to utilize mask and filter functionality of checking first two data bytes for Standard CAN ID frames. (A mask or filter entry for standard IDs will look similar Extended IDs. 0x07FF0000 The first nibble is unused, the last four nibbles are the two data bytes.) Cleaned up function descriptions. Removed 'getCanId' function.

This demo only applies to standard IDs.
This demo only applies to extended IDs.
…d.ino Added sent message status information. Cleaned up descriptions.
…e/CAN_receive.ino Added initialization information to detail success or failure.
During initialization, the MCP2515 is put in loopback mode. This seems to allow the masks and filters to set without undesired behavior when connected to an operating, utilized bus. Also uncommented the section for 8MHz crystal baud rate selection.
Added definitions for 8MHz crystal baud rate selection.
Moved MCP2515 mode change to after all initialization commands.
Moved MCP2515 mode change to after all initialization commands.
Fixed a small bug I caused from the previous edit...

This is a bad idea... |
Added error functions and fixed return values on public functions as a well as added two other functions for differing user preferences.
