Add a deterministic state transition when I customize AN75779?
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.
