    the output frame rate of cx3

    sl.lee_1656711

      Hi,

      I've a problem that the output frame rate of cx3 usb only half of the input.

       

      The sensor's VS is 30Hz.

      The VSYNC_TEST in cx3 is 30Hz.

      I can get correct image frames from USB but the frame rate is only 15Hz.

      I measure a gpio that toggle in the callback function of GPIF while get the event "CYU3P_GPIF_EVT_SM_INTERRUPT".

      The frequence is 7.5Hz. That means the frequence of this event is 15Hz.

      What is the cause of this problem?

       

      Regards,

      Lee
