IWR1642 BoosterPack™︎ evaluation module for single-chip 77GHz mmWave sensor

Other Parts Discussed in Thread: IWR1642BOOST, IWR1642

Hello! We want to communicate with the IWR1642boost radar through the LAN gateway.( connection to the radar through the pins of J5 and J6), For this purpose, we have designed a board with the STM32F107RC6 microcontroller. However, we are unable to send and receive configuration via UART with the radar's RS232TX/RX of IWR1642boost. We used HAL_transmit/receive functions in our microcontroller programming. It enters the send function, but we're not receiving anything (the mmwDemo:/> prompt is not received)..We can't establish communication with any of the radar's UARTs(like RS232 and MSS logger). Where is the issue in our work? 

(We established communication with the radar board via USB and the demo Visualizer.)

Please guide us. Thank you.

    Hello Sharifi,

    Please allow us couple of days to look into this query.

    Hi Sharifi,

    The IWR1642 device does not support LIN IP. We need to port/mimic UART protocol on STM32F107RC6 microcontroller. Kindly check if the baud rate, electrical specifications are within the UART specifications.

    TI demo flashed on the devices sends out data on MSS_LOGGER_Tx pin. Please ensure this MSS_Logger_Tx pin need to be connected to RX port of the UART/LIN interface. If you take a look at the schematic for the IWR1642BOOST, you will see that the MSS logger is already connected to the XDS110, you will need to bypass XDS110 and connect MSS_logger to RX pin of the UART/LIN interface of STM32F107RC6.
