MMWAVEPOEEVM: How to use

MSP432E401Y: POE - Ethernet to UART demo code - guidelines

Part Number: MSP432E401Y
Other Parts Discussed in Thread: MMWAVEPOEEVM

Tool/software:

Hi, 

We want to use the MMWAVEPOEEVM with the MMWAVEICBOOST as explained in the ref design. 

The MMWAVEPOEEVM includes a MSP432 and according to the E2E https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1045326/mmwavepoeevm-how-to-use the application on the MSP432 needs still to be developped. 

The application is bascially an Ethernet to UART bridge where the MCU manage the Ethernet communication to the host through the RJ45 port and the UART communication with the radar. 

Can you please provide a guideline on how to implement that ? From which example would you start etc... ? 

Thanks,

Geoffrey

    Hi,

      We don't have a simple MSP432E bare metal example for Ethernet to UART bridging. You can find several "bare-metal" Ethernet examples in C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\lwip. These examples are based on the open-source lwIP TCP/IP stack. The ethernet-based_io_control example also demonstrates various i/o control capabilities such as Ethernet to UART bridging.  

    If you are interesting using RTOS based application, you can also refer to examples in C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\rtos\MSP_EXP432E401Y\ns. I will suggest you start with tcpecho where data is sent and received to the MCU acting as a echo server. Here you can modify the code such that the received data by the echo server is routed to the UART or vice versa.
