各位高手，在下问一个关于CAN总线的问题，从MICROCHIP网站下载了AN0738的源码，使用中发现，程序不能发送数据，但可以接收数据，为什么？还有我看到CANSendMessage子程序里面没有关于TXB0REQ的设置，如果人为的加进TXB0REQ=1;这一句，单片机就死机，不知何解，以下是我的源码，望各位高手赐教！！
void main() { CANInitialize(1, 2, 4, 3, 2, CAN_CONFIG_PHSEG2_PRG_ON&CAN_CONFIG_LINE_FILTER_OFF&CAN_CONFIG_SAMPLE_ONCE&CAN_CONFIG_VALID_STD_MSG&CAN_CONFIG_DBL_BUFFER_OFF&CAN_CONFIG_STD_MSG); CANSetOperationMode(CAN_OP_MODE_CONFIG); CANSetMask(CAN_MASK_B1,0X0000000F,CAN_CONFIG_STD_MSG); CANSetFilter(CAN_FILTER_B1_F1,0X00000001,CAN_CONFIG_STD_MSG); CANSetOperationMode(CAN_OP_MODE_NORMAL); while(1) { if(CANIsTxReady()) { MessageData[0] = 0x01; MessageData[1] = 0x02; CANSendMessage( 0x10,MessageData,2,CAN_TX_PRIORITY_0&CAN_TX_STD_FRAME &CAN_TX_NO_RTR_FRAME); } if(CANIsRxReady()) { CANReceiveMessage(&NewMessage,NewMessageData,&NewMessageLen,&NewMessageFlags); } } // Do this forever }// End of program
