HI,

I want do load the CAN ID and data.

how to write the  code do to that?

I set the message box9 ID is 0x14EA01EF.

I set the int variable "u32temp" to read the ID,but it can work.

    Hi Kuanlee,

    1. You need to transfer the message arbitration or ID from message RAM to IFx register

         canREG1->IF1CMD = 0x20U;

         canREG1>IF1NO = messageBox;

    2. then read the ID from IFx register

        u32temp = node->IF1ARB

    You can use canGetID(...) in can.c to read the message ID.
