Hi,

What type of output are you trying to trigger. Would toggling a GPIO be fine?

Thank you

Hi,

Sorry for the delay

Please look at:

MmwDemo_transmitProcessedOutput()

C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\mss\mss_main.c

You will be interested in MMWDEMO_OUTPUT_MSG_DETECTED_POINTS

Th e packet information is described in

C:/ti/mmwave_sdk_03_05_00_04/packages/ti/demo/xwr18xx/mmw/docs/doxygen/html/index.html

Please see "Output information sent to host", "List of detected objects". the format is float

thank you
