The FlyCapture API library has function calls to get and set camera register values. These function calls automatically
take into account the base address. For example, to get the 32-bit value of the SHUTTER register at 0xFFFF F0F0 081C:
FlyCapture v1.x:
flycaptureGetCameraRegister(context, 0x81C, &ulValue);
flycaptureSetCameraRegister(context, 0x81C, ulValue);
FlyCapture v2.x (assuming a camera object named cam):
cam.ReadRegister(0x81C, &regVal);
cam.WriteRegister(0x81C, regVal, broadcast=false);
