IWRL6432: IWRL6432 SYNC_IN with delayed frame trigger

Jens Lindrup

Part Number: IWRL6432


Hi.

I am using an IWRL6432. I want to use the SYNC_IN pin to trigger frames. As far as I can see, it is possible to use the FrameTrigMode to HW_LOW_JIT_TRIG. image.png

However, according to the datasheet, I can set a delay for the frame start. image.png

This is visualized here:

However, I am not able to find the delay in the source code or configuration. Can you help me find it in the source code?

My application uses two sensor with an overlap, so I need to delay one of the sensors, to avoid ghost points.

Thank you in advance.

    Hello, 

    Please refer to the documentation for the frame trigger delay in the interface control document. Search for 'w_FrameTrigTimerVal' ({MMWAVE_L_SDK_INSTALL}\firmware\mmwave_dfp\docs\mmwave_dfp_interface_control_document.pdf)

    Best regards,

    Josh

    Dear Josh,

    Thank you for your message. w_FrameTrigTimerVal is applicable only in software trigger mode as per the interface control document. I was under the impression that there is another delay, that can be used to delay the frame trigger when using the hardware trigger mode.

    Hi, 

    I apologize, your latest reply was missed by me. Please let me check to confirm if a separate programmable delay is available for HW trigger mode and get back to you in 1-2 days. 

    Regards,

    Josh
