TI中文支持网Part Number:TMS320F280049Other Parts Discussed in Thread:SYSCONFIG
您好，目前我在使用280049进行CAN通信时发现了一些问题。
在sysconfig中对CAN进行配置时，对mailbox1的ID配置为1，如图所示
通过上位机进行通信时，发现也可以正常通信。
但我希望能够在寄存器位上对ID进行查看，发现只能看到IF1ARB等寄存器中的ID，且运行过程中的ID和程序配置的ID的对应方式我也不是很清楚。想请问一下，我该从哪个寄存器去看每个message object的ID，谢谢。（类似在28335中，每一个mailbox对应有一个寄存器看MSGID，如下）
目前配置的是message objectx的message identifier是x，共配置了1，2，3，4四个，其中2是receive，其余是transmit。观察send和receive的函数发现，send用的IF1，receive用的IF2，两个寄存器对应的ID如图所示。

或者说，我想请问一下DCAN中配置的帧ID和最后在数据帧上的ID，二者之间的对应关系是什么

消息 ID 位于 IFxARB 寄存器中。 消息 ID 由 can_sendMessage()编程、并由 can_readMessageWithID()读取。
