Part Number: TIDA-010935
Other Parts Discussed in Thread: LP-MSPM0G3507, THS6222, THVD8000

Tool/software:

Hello
I am trying PLC Uart example with two TIDA-010935.

I'm uploaded firm ware each board.
first, upload TIDA_010935_UART_echo
second, upload TIDA_010935_UART_ext_loopback.

then, each boards Connect PC with usb.
PLC Line is Connecting J2 and J3 Port in TIDA-010935.
PLC DC Power Voltage is 24V.

Then, sending data with Uart ext loopback board.

next, check receive data with Uart echo board.


Do I understand that correctly?
I'm refer to  TIDA-010935 Reference file.
but, I'm ambiguous understand about Is this what I thought.

I'm sharing reference link and screenshot.

    Hi,

    Thanks for reaching out.
    You need to upload TIDA_010935_UART_ext_loopback. to Board 1
    and and TIDA_010935_UART_echo to the board 2.

    Then you can send a message from board 1.
    Board 2 will receive the message and echo this message back to board 1.
    Then you can check on board 1 again if the received message is the same one as the sent message.

    Best regards,

    Andreas

    Hello

    thank you for your answer.

    I have a new question.
    what is use the Uart port for data transmit and receive?

    Uart Port have a occupied UART1(PA8, PA9 PIN).
    This UART1 Port send data or receive?


    LP-MSPM0G3507 have a USB Port in UART0(PA10, PA11).

    if Send and Receive data with usb port, need fix firmware code?

    Hello,

    This is bidirectional. So you send and receive on UART1 port. Please refer to syscfg file of the examples to see which UART port is used.

    We don't support sending data via USB. The data is sent from UART port 1 to THVD8000 then amplified with THS6222 and sent via the power line which needs to be connected on the screw terminals J2 and J3.

    Best regards,
    Andreas
