*(unsigned long *)ucMsgData_TX = 0; sCANMessage_TX.ulMsgID = 0x000007DF; // CAN message ID - use ECU's ID:0x000007DF sCANMessage_TX.ulMsgIDMask = 0; // no mask needed for TX sCANMessage_TX.ulFlags = MSG_OBJ_TX_INT_ENABLE; // enable interrupt on TX sCANMessage_TX.ulMsgLen = sizeof(ucMsgData_TX); // size of message is 8 sCANMessage_TX.pucMsgData = ucMsgData_TX; // ptr to message content
// 以下代码是配置CAN RX部分报文初始化。 // // Initialize a message object to be used for receiving CAN messages with // any CAN ID. In order to receive any CAN ID, the ID and mask must both // be set to 0, and the ID filter enabled. //
sCANMessage_RX.ulMsgID = 0; // CAN msg ID - 0 for any sCANMessage_RX.ulMsgIDMask = 0; // mask is 0 for any ID sCANMessage_RX.ulFlags = MSG_OBJ_RX_INT_ENABLE | MSG_OBJ_USE_ID_FILTER; sCANMessage_RX.ulMsgLen = 8; // allow up to 8 bytes
// 以下是CAN RX 数据由UART发送至PC。
// // Print out the contents of the message that was received. // UARTprintf("Received Msg:ID=0x%08X len=%u data = 0x", sCANMessage_RX.ulMsgID, sCANMessage_RX.ulMsgLen); for(uIdx = 0; uIdx < sCANMessage_RX.ulMsgLen; uIdx++) { UARTprintf("%02X ", ucMsgData_RX[uIdx]); } UARTprintf(" total count = %u\n", g_ulMsgCount_RX);
