Dear friends!

I have one unsolved problem: I need more than 64 CAN-messages, but I can set only 64 Message Boxes.

So, what solution can you tell me? Thanks

Hi Vladislav,

TMS570LS1224 has 3 DCAN controllers, and each CAN controller has 64 mailboxes. Can you use 2nd CAN controller for extra mailmoxs?

Hi, QJ Wang! No, I cann't. I've got 9 devices on the bus, 8 Message boxes are required to communicate with each device - 3 for transmitting and 5 for recieving.

Hi Vladislav,

You can use one DCAN message box to transmit messages with different IDs which are received by 2 or more receiving message boxes in device.
