TMS320F280049: CAN message and ID operation

Daniel Fang

Part Number: TMS320F280049

Hi 

1. It setup two message,  ID 1 and ID 3.

Use CAN analyzer to send data. Message 1 can receive data successfully but message 3 is failed. Is there any more configuration code need or not besides of below setting?

2： ID read and write

   When we receive, it needs to receive the ID firstly, to determine whether it is the mailbox, and then receive data. The current API only provides a function to receive data. Nothing about how to receive ID.

3. In addition, customer use multiple 280049 working together to share the current. In order to coding ID number and sorting. How to change ID to write? 

Thanks.

    1. You are setting it to use message objects 1 and 3. Each message object setup is using the same message ID (0x800421e0). I believe message is going to the highest priority message object.
    2. If you want to read other details of the message object, you can use CAN_transferMessage to read the message object details/data into the interface registers
    3. I don't follow what you are asking here.

    Best regards
