hi 

i write a program which want to send can message and receive can message.

I referred to an article and then adapted it. but when i debug it, i find my program can not send message .

according to the reference manual, each successful transmission or reception sets the corresponding IFLAG1 bit. But when i send message, the IFLAG1 bit not be set. So the message send failed.
