Hello,
The MCP2515 or MCP2510 configuration is done with the SPI interface bus; it is not really 'programming' since it has to be done after each power on.
I suppose you can do it with the supplied CCS libraries, I never tested them (I rewrote my own lib, to fit in PIC16F84 memory...) |

| Yes, but you should read the library because it defines some settings you will have to change (PIN connection betwen PIC and MCP, MCP baud rate generating bit setting to define CAN BUS speed...) |
