+ *   Example project demonstrating the OpenMote-CC2538 functionality
+ *
+ *   This assumes that you are using an OpenMote-CC2538
+ *
+ * - Boot sequence: LEDs flashing, LED2 followed by LED3 then LED4
+ * - etimer/clock : Every LOOP_INTERVAL clock ticks the LED defined as
+ *                  LEDS_PERIODIC will turn on
+ * - rtimer       : Exactly LEDS_OFF_HYSTERISIS rtimer ticks later,
+ *                  LEDS_PERIODIC will turn back off
+ * - UART         : Every LOOP_INTERVAL the EM will print something over the
+ *                  UART. Receiving an entire line of text over UART (ending
+ *                  in \\r) will cause LEDS_SERIAL_IN to toggle
+ * - Radio comms  : BTN_SELECT sends a rime broadcast. Reception of a rime
+ *                  packet will toggle LEDs defined as LEDS_RF_RX
