    Add a deterministic state transition when I customize AN75779?

      Hi Cypress,

         

      I am trying to customize the AN75779 to add in controls like snapshot or series of shots. 

         

      I use FPGA as data source in place of the image sensor. The current UVC state machine runs continuously. 

         

      When I implement a snapshot routine, is the following feasible? 

         

      1) IIC_Write to FPGA to stop FV/LV, Disable GPIF with CyU3PGpifDisable

         

      2) CyFxUvcAppGpifInit, CyU3PDmaMultiChannelReset, and CyU3PUsbFlushEp

         

      3) CyU3PDmaMultiChannelSetXfer, CyU3PGpifSMStart at START_SCK0

         

      4) IIC_Write to FPGA to capture frame and activate FV/LV into FX3.
