Snapshot button interface for still image capture [ Using CX3 / FX3 ]
I am using CX3 for USB 3.0 webcam development.
In the project, still image capture need to be triggered both
- by PC (Window 7 or 8) application SW.
- by camera device's snapshot button.
SW triggering is done, but HW triggering cannot find how.
As I assume, the sequence will be
[raise endpoint interrupt to HOST] -> [Host issue still capture event] -> [remaining same as SW triggered case]
But I cannot figure out how to code for it.
Can someone show me some example code?
