-/**
- * Hal.h -- HAL Interface Definitions
- *
- * This example HAL is intentionally simple. The implementation is limited to:
- *
- * BUTTON -- a single button that when pressed will cause an interrupt.
- * DEBUG -- two debug GPIOs that are available as outputs from the EAP and under user control.
- * DELAY -- a delay routine that can delay by n milliseconds.
- * INIT -- set the hardware up to its initial state
- * LED -- a user LED that is available for application control.
- * TICK -- a timer that can be set to interrupt every n milliseconds
- * IDLE LOOP -- an event driven idle loop for controlling the EAP
- *
- * For information on Hal implementations for specific target hardware platforms,
- * visit the http://wiki.em-hub.com/display/ED.
