[参考译文] TMS570LS1114：CAN 问题

对于 CAN 2和 CAN3没有什么特别之处。

当您调用 canTransmit()和 cangetData()： canREG2时，是否使用了 CAN2的正确寄存器帧指针？

CANInit()中是否启用了 CAN2和 CAN3？

感谢你的帮助。

1.在调用 canTransmit()和 cangetData()时，是否为 CAN2使用正确的寄存器帧指针： canREG2？

我想 我 是对的。我会给你 我的程序、请看一下。

CANInit()中是否启用了 CAN2和 CAN3？

是的、当然。我启用所有 CAN (CAN1/CAN2/CAN3)驱动器。

void can_function(void)
{

	u8gv_tmr_addr = get_sdm_addr();
	if (u8gv_tmr_addr == ADDR_TMR_A)
	{

		canTransmit(canREG1, canMESSAGE_BOX1, (const uint8 *)&tx_data1[0]);		//CAN1 sends data1 to A and B
//		canTransmit(canREG2, canMESSAGE_BOX1, (const uint8 *)&tx_data1[0]);		//CAN2 sends data1 to C
//		canTransmit(canREG3, canMESSAGE_BOX1, (const uint8 *)&tx_data1[0]);		//CAN3 sends data1 to B

		canGetData(canREG1, canMESSAGE_BOX5, (uint8 *)&rx_data1[0]);	//CAN1 receive data for B
		canGetData(canREG1, canMESSAGE_BOX6, (uint8 *)&rx_data1[0]);	//CAN1 receive data for C
//		canGetData(canREG3, canMESSAGE_BOX5, (uint8 *)&rx_data1[0]);	//CAN3 receive data for B
		canGetData(canREG2, canMESSAGE_BOX6, (uint8 *)&rx_data1[0]);	//CAN2 receive data for C
	}
	else if (u8gv_tmr_addr == ADDR_TMR_B)
	{
		canTransmit(canREG1, canMESSAGE_BOX2, (const uint8 *)&tx_data2[0]);		//CAN1 sends data2 to A and C
		canTransmit(canREG2, canMESSAGE_BOX2, (const uint8 *)&tx_data2[0]);		//CAN2 sends data2 to A
		canTransmit(canREG3, canMESSAGE_BOX2, (const uint8 *)&tx_data2[0]);		//CAN3 sends data2 to C

	}
	else if (u8gv_tmr_addr == ADDR_TMR_C)
	{
		canTransmit(canREG1, canMESSAGE_BOX3, (const uint8 *)&tx_data3[0]);		//CAN1 sends data3 to A and B
		canTransmit(canREG2, canMESSAGE_BOX3, (const uint8 *)&tx_data3[0]);		//CAN2 sends data3 to B
		canTransmit(canREG3, canMESSAGE_BOX3, (const uint8 *)&tx_data3[0]);		//CAN3 sends data3 to A
