LP-MSPM0G3507: CAN interface

Part Number: LP-MSPM0G3507
Other Parts Discussed in Thread: MSPM0G3507

Hello TI,,

I am recently  go through the LP-MSPM0G3507 for CAN -FD interface , I get some example code for the same on  the Resource explore , so I simply took the example code and modify  the same in order to transmat the data continuously without any other function and as per my understanding as I flash the code inside the MCU it should give some signal on Tx pin of CAN , I connect the Tx Pin ( as I know CAN Tx and Rx pin was PA12  and PA13)

of CAN to Oscilloscope with respect to GND to check the Tx pin signal , as I flash the code I always getting HIGH signal (I expect that should be high low kind of thing there is that not ? ), Please let me know how i can check the CAN module with help of Oscilloscope or less peripheral.

Thanks and regards,

    Hi Arjun,

    Which example are you using exactly?

    In the mcan_multimessage_tx_LP_MSPM0G3507 example, you will see some activity on the TX pin when you first press the button on the launchpad to initiate a transaction. 

    I expect would not see another transaction after that without a can transceiver and another device connected running the corresponding RX example. See the README file for your example to see what hardware the example was tested with. 

    Best Regards
