CAN not working properly

I would like to use CAN protocol with shield Buddy. The code work with Arduino mega. but the same code not working with shield buddy. I seen the clock signal duty cycle is not 50%. is it any problem?  I attached the used library and my little test program. CAN_BUS_Shield-master.zip (19.31 KB)CAN_send_uno_mcp_can.ino (1.17 KB)


 Thanks for your help
