hello

   when i call the function byte MSCAN0_SendFrameExt(dword MessageID,byte FrameType,byte Length,const byte *Data),

it returns ERR_TXFULL,i check the register CANTFLG = 0x00,it means message duffer is full,so i don`t konw why buffers are all full?

 

   i conncet a kvaser CAN data analysis as the other node,and this is my Processor Expert configuration
