is it possible to use the on-board launchPad compatible 40pin connector to trigger external device?

(for example, IP camera with DIO trigger)

    Hi, 

    Yes this is possible. GPIO_5 is routed to J8.15. 

    There is however an analog mux, so you must ensure that S1.6 is in the off position. 

    Please also refer to the gpio example code at: {MMWAVE_L_SDK_INSTALL}\examples\drivers\gpio

    Best Regards,

    Josh
