Other Parts Discussed in Thread: TCAN4550, MSP-EXP430FR6989

Hi,

How can we test two EVB connect to each other is OK?
For example, if we have two device EVB-1 and EVB-2 connect to each other.
Do you have tool or something can test the connection status of each other?
For example EVB-1 send a message to ask EVB-2 battery capacity , after EVB-2 receive this message would feedback the information back to EVB-1.
Please provide tool or document if you have.

    Hi,

    We have sample code available for our MSP-EXP430FR6989 launchpad development kit to evaluate TCAN4550. This code configures the SBC for CAN communication with another node, and is capable of communicating back and forth with another TCAN4550 device running the same program. This development kit is ideal for use with the BOOSTXL-CANFD-LIN booster pack, as it can be placed on top without the need for jumper wires. 

    If you will be using your own setup with the TCAN4550EVM, this code can also be modified to work with other MCUs with a SPI interface to correctly configure TCAN4550 for this test program. 

    Let me know if you have any questions or would like any information on these tools. 

    Regards,
    Eric Schott

    Hi Eric,

    TCAN4550 are porting in two LINUX platform devices.
    Can these two devices communicate to each other without MSP-EXP430FR6989 as you mentioned ?
    Because our final product won't have MSP-EXP430FR6989 , so if it is possible , we want to test it without MSP-EXP430FR6989.

    As above I mentioned, does the sameple code you mentioned can help us?
    If this can help us, where can I find it?

    Thanks.
    Jeff.

    Hi Jeff,

    The sample code contains the high-level logic needed to configure the TCAN4550 for the situation I described above. This code can be applied to any controller as long as it is capable of driving a SPI interface to communicate with TCAN4550. The code can be found at this link.

    My initial reply also contains hyperlinks throughout where code and boards can be found. It looks like the format has changed since the recent E2E update so it's not as visible. If you scroll over the text, it will highlight as a hyperlink.

    Let me know if you have any trouble finding the correct webpages. 

    Regards,

    Hi Eric,

    Thanks for help.
    I search the link page you provide and download a file  as below.

    TCAN4550 Demo Software (Rev. B) – SLLC469B.ZIP (1176KB)

    Is this the sample code you mentioned?

    Thanks.
    Jeff.

    Hi Jeff,

    Yes, this software is what I would recommend to get you started. The "tcan4x5x" folder contains all of the TCAN4550 specific drivers that can be used in any C program.
