TMS320F28377D: How to use the same Mailbox for multiple CAN messages in Simulink

Hi Kash,

I know that I'm limited with 32 Mailbox for CAN communication which means I can have up to 32 distinct CAN message. I'm wondering if there is any way (in Simulink and/or CCS) to use the same Mailbox for multiple messages so I would be able to have more than 32 messages. 

Is this for transmission or reception? In both the cases you can very well configure Mailbox to handle multiple messages.

Gautam,
I can configure Mailboxes to transmit and receive 32 messages. I want to know how to use Mailboxes for more than 32 messages. I can't use the same Mailbox number in two distinct CAN blocks in Simulink because an error pups up says the Mailbox number has already been used.

Did you try implementing Masking feature? In CCS this is very well possible but I've not tried the same in Simulink. By using the masking feature you can send receive 1000s of messages (ie with different message ids) through 1 Mailbox itself.

I did not. I don't want to use CCS for this purpose but will try to see how I can implement Masking feature in Simulink.
Thanks for your advice Gautam.

Do check and let us know. Do try posting your query on Matlab forum too.

Sure, I will keep you updated.
