^^^^^^^^^^^^^^^^^^
This is a simple test of the discrete joystick driver. See details about
this driver in nuttx/include/nuttx/input/djoystick.h.
Configuration Pre-requisites:
CONFIG_DISABLE_SIGNALS - Must *NOT* be selected
CONFIG_DJOYSTICK - The discrete joystick driver
Example Configuration:
CONFIG_EXAMPLES_DJOYSTICK - Enabled the discrete joystick example
CONFIG_EXAMPLES_DJOYSTICK_DEVNAME - Joystick device name. Default
"/dev/djoy0"
CONFIG_EXAMPLES_DJOYSTICK_SIGNO - Signal used to signal the test
application. Default 13.
