on 2011-10-10 so I presume that the code is stable and there is no risk
of maintaining duplicate logic in the NuttX repository.
examples/keypadtest
^^^^^^^^^^^^^^^^^^^
This is a generic keypad test example. It is similar to the USB hidkbd
example, but makes no assumptions about the underlying keyboard interface.
It uses the interfaces of include/nuttx/input/keypad.h.
CONFIG_EXAMPLES_KEYPADTEST - Selects the keypadtest example (only need
if the mconf/Kconfig tool is used.
CONFIG_EXAMPLES_KEYPAD_DEVNAME - The name of the keypad device that will
be opened in order to perform the keypad test. Default: "/dev/keypad"
examples/lcdrw
^^^^^^^^^^^^^^
