Before you run the example, let's learn how the gamepad work.
The gamepad included supports two working modes. One is PC/PS3/Andorid mode and another is Xbox 360 mode.
The gamepad is set to PC/PS3/Andorid mode by default, in this mode, the gamepad has two sub-modes. You can press the HOME button to switch it. In Mode 1, the front panel lights on only one LED, the right joystick is mapped to buttons 0,1,2 and 3, and you can get only 0 or -1/1 value from the joysticks. In Mode 2, the front panel lights on two LEDs, the right joystick is mapped to axes[2] and axes[5]. In this mode, you can get No intermediate values from joysticks.

To switch between PC/PS3/Andorid mode and the Xbox 360 mode, you can long-press the HOME button for about 7s. In Xbox mode, the left joystick is mapped to axes[0] and axes[1], right joystick is mapped to axes[2] and axes[3]. This mode is exactly what the NVIDIA examples use. We recommend you to set your gamepad to this mode when you use it. Otherwise, you need to modify the codes.

If libASICamera2.so or (.dylib) can't be found at run time, resolve by delow two ways:
1.Add a .conf file that contains the path of the library to /etc/ld.so.conf.d/, run ldconfig.
2.Add compile option -Wl,-rpath=<library path>
