hi Sir

 

We are LED driver manufacturer, next generation product need to support The DMX togolopy

    We can use UART to handle the DMX protocol, but need a transceiver to convert UART Tx to DMX signal(since it based on RS-485, a RS-485 transceiver is needed).

    For the DMX break field, M0 can handle it by software control the UART Tx logic.

    You can find demo of bridge here:
    C:\ti\mspm0_sdk_2_07_00_05\examples\nortos\LP_MSPM0G3507\msp_subsystems

    It uses standard UART, you need to modify the send function to fit DMX protocol.
