CAN email configuration for S32K144?

[leonordo]

When I configure the can mailbox of S32K144, should I configure this register to configure the maximum number of mailboxes of S32K144?

CAN0->MCR = 0x0000000F | CAN_MCR_SRXDIS(1); /* Negate FlexCAN 1 halt state for 32 MBs */

After the configuration is complete, the can IFLAG register is checked and the received data is stored in only one mailbox. All the other mailboxes are empty

Hi leonordo,

Please refer to the examples in the article: S32K1xx SDK FlexCAN sample projects to demonstrate its basic and advanced features

Best Regards,

hello,I would also like to ask that if I increase the size of an mailbox, for example, one mailbox CAN receive two messages, then I can read two days' CAN data in one mailbox at a time

Hello, I have solved the problem before, because I did not initialize the mailbox configuration;

Now I have another question: Can S32K144 email address not be configured as:

Three mailboxes receive the same ID at the same time, mailbox one is full, mailbox two is receiving, and so on until all three mailboxes are full

Sorry for the delay.
