LAUNCHXL-F28069M: How to copy the MDL and MDH data of a particular mailbox of CAN into a variable

Hi Sunita,

The example in C2000ware demonstrates the same:  "ecan_back2back"

C:\ti\c2000\C2000Ware_1_00_05_00\device_support\f2806x\examples\c28\ecan_back2back

//
// mailbox_read - This function reads out the contents of the indicated
// by the Mailbox number (MBXnbr). MSGID of a rcv MBX is transmitted as the 
// MDL data.
//
void
mailbox_read(int16 MBXnbr)
{
    volatile struct MBOX *Mailbox;
    Mailbox = &ECanaMboxes.MBOX0 + MBXnbr;
    TestMbox1 = Mailbox->MDL.all;   // = 0x9555AAAn (n is the MBX number)
    TestMbox2 = Mailbox->MDH.all;   // = 0x89ABCDEF (a constant)
    TestMbox3 = Mailbox->MSGID.all; // = 0x9555AAAn (n is the MBX number)
}

Respected sir,

I have referred this. My message id get copied in a variable but data high and low are not copying using this.

Did you use the same sample code - as it is?

hello sir

actually I am using the code from eCAN programming examples. In that I have added the loop of mailbox read (at receiver side)because I want to copy the id and data of one mailbox and want to send it to another mailbox (3rd node). For this purpose I want to copy the id and data into a variable.

Is this post related to :e2e.ti.com/.../2722236

Yes sir, both the threads are initiated by me but my questions are quite different, that's why I have posted them differently. TI told me to do so.

Was this resolved?

No sir, My issue is not resolved. I didn't get the actual answer to my original question.
Kindly reply accordingly as soon as possible.

Respected sir,
Now my data and Id both copied in a variable successfully using TXLOOP_A code from my app notes. I have developed my own logic
Thank you Sir!
