guys,i finally got it working.there were some problems.i connected the reset pin of mcp2515 to5v through 10k.i changed it and connected it to pinc1 of pic.then the main problem was configuration of cnf1,cnf2 and cnf3 registers.i had to configure it for 20mhz crystal.i will attach my final code here.
