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.
