AWR1843: Hardware Trigger Using the SDK Demo

Part Number: AWR1843


Does the SDK Demo MSS enables the use of hardware trigger using the GPIOs? If not how can I add support for this feature?



  • Hello Yuval,

    There is no provision to directly use the hardware trigger.
    To read more about this feature you will have to go through the interface control document, which is available if you download the dfp package
    Then you can go to the C:\ti\mmwave_dfp_01_02_06_03\docs\mmWave-Radar-Interface-Control.pdf
    Ther you can go the section 5.5.3 Sub block 0x0102 – AWR_FRAME_CONF_SET_SB, if you go to page 85, 86 it explains how the pulse should be configured.
    Then you will need to maintain the sync time with the GPIO (initialize this GPIO using the driver) using a timer in the Application code and this is how you will be able to trigger the frame externally.

    Adding the picture from the interface control document for reference:
