+ This is a simple configuration that may be used to test the board-
+ specific button interfaces. Configuration options:
+
+ CONFIG_ARCH_BUTTONS - Must be defined for button support
+ CONFIG_EXAMPLE_BUTTONS_MIN - Lowest button number
+ CONFIG_EXAMPLE_BUTTONS_MAX - Highest button number
+
+ CONFIG_ARCH_IRQBUTTONS - Must be defined for interrupting button support
+ CONFIG_EXAMPLE_IRQBUTTONS_MIN - Lowest interrupting button number
+ CONFIG_EXAMPLE_IRQBUTTONS_MAX - Highest interrupting button number
+
+ Additional architecture-/board- specific configuration settings may also
+ be required.

+# CONFIG_SCHED_WORKQUEUE. Create a dedicated "worker" thread to
+# handle delayed processing from interrupt handlers. This feature
