Button on Microscope QX3

[nicolacdnll]

Hi,
I'm working on a Java software for using the microscope QX3 in the primary school and I need a way to figure out when the user press the button on the microscope. I can't get this from V4L2 library, so reading the CPiA(1) - gspca driver, I found the var button on the struct qx3:

struct {
  /* Intel QX3 specific data */
  u8 qx3_detected; /* a QX3 is present */
  u8 toplight;     /* top light lit , R/W */
  u8 bottomlight;  /* bottom light lit, R/W */
  u8 button;       /* snapshot button pressed (R/O) */
  u8 cradled;      /* microscope is in cradle (R/O) */
} qx3;

Could someone kindly tell me if there is a way to read this value?

Thank you for your time.

Well, this is a C structure, not a Java one, so you probably need to either write a C/C++ program that can get this data and send it to your java application, or you can embed it into your java app and access it via a JNI function call. Unfortunately, since I am not familiar with this API I don't know what more to suggest, although remember that Google is your friend!
