CAN communication in dsPIC33CK64MP508

[surendran_raj]

I tried to transmit data using CAN communication in dsPIC33CK64MP508. I use MCC for configuring CAN in dsPIC33CK64MP508 and MCP2551 CAN transceiver. I set the bit rate to 500 kbps. I just transmit two data bytes (0x41 and 0x42) and I used a logic analyzer to view the data but it shows the error.

I have attached my output data using a logic analyzer. Can anyone please correct me?

int main(void)
{
    // initialize the device
    CAN_MSG_OBJ msg;
    uint8_t data[2] = {0x41,0x42};
    SYSTEM_Initialize();
    CAN1_OperationModeSet(CAN_CONFIGURATION_MODE);
    if(CAN_CONFIGURATION_MODE == CAN1_OperationModeGet())
    {
        if(CAN_OP_MODE_REQUEST_SUCCESS == CAN1_OperationModeSet(CAN_NORMAL_2_0_MODE))
        {
            msg.msgId = 0x1FFFF;
            msg.field.formatType = CAN_2_0_FORMAT;
            msg.field.brs = CAN_NON_BRS_MODE;
            msg.field.frameType = CAN_FRAME_DATA;
            msg.field.idType = CAN_FRAME_EXT;
            msg.field.dlc = 2;
            msg.data = data;
            
            if(CAN1_IsBusOff() == false)
            {
                if(CAN_TX_FIFO_AVAILABLE == (CAN1_TransmitFIFOStatusGet(CAN1_TX_FIFO1) & CAN_TX_FIFO_AVAILABLE))
                {
                    CAN1_Transmit(CAN1_TX_FIFO1, &msg);
                }
            }
        }
    }
    while (1)
    {
        // Add your application code
    }
    return 1;
}

output in Logic analyzer

but it shows the error.

What error does it show?
What do you expect?

@KlausST
Thanks for your response. I used a logic analyzer to view the transmitted data but it shows a CAN error.
I need to view the transmitted data to check wheater the transmitted data is correct or not.

 

[KlausST]

it shows a CAN error.

Where?

@KlausST

error highlighted in white box

 

[KlausST]

I give up.

 

[surendran_raj]

I give up.

I mean i can't view transmitted data when use it with STM I can able see the transmitted data and transmitter id
