Part Number: AWR1843

Hi Expert,

Customer would like to know all the information to the way to frame sync among some AWR1843s (it is different from cascade).

Question#1: 

     The following CLI commands should related to do it.

      - Hardware Trigger at "trigger select" on frameCfg

      - Transfer a charp by issue the sensorStart command

      Is anything related to do it ?

Question#2:

      In addition to above, SYNC_OUT of Synchronization source and SYNC_IN of Synchronization dest should be tied each other.

      

      Is anything needed?

Thanks and Best regards,

HaTa.

    Hello HaTa,

    1. For Frame configuration, Configure the master as usual (i.e software triggered)

    When configuring the slave, select hardware triggered mode in the frame-config API. All other APIs will remain unchanged.

    2. Yes, you are right. For frame synchronization, one device is configured as the master, and the other device as slave. The slave device receives the AR_SYNC_IN signal from the master device every time the master device begins the transmission of a frame. 

    For reference, you might also want to refer to the below thread :
