TMS320F28030: CAN protocol support

Viki Shi

Part Number: TMS320F28030

Hi Team,

My customer need some help with our F2803X device, please check the description below:

My rectifier based on F2803X development and contains two different CAN protocols.These CAN protocols won't be effective at the same time.

Question: does F2803X support two CAN protocols and free to replacement? For example, by detecting a GPIO level high output CAN protocol A,the level low output CAN protocol B.

Thanks a lot!

Best regards,
Viki

Please clarify what you mean by the word “protocol”. CAN itself is a protocol. Are you referring to Higher-layer protocols such as CANopen?

"Different CAN protocol" means two different eCAN Message ID [MSGID]. One program is compatible with two MSGID bit definitions.

You can use any number of MSGIDs. There are 32 mailboxes and you can use a different MSGID for each.
