Antonio Lignan 330e450ba4 Zolertia Re-Mote platform ported to Contiki, developed whitin RERUM FP7 European project (grant #609094).
The port was done jointly by Zolertia and George Oikonomou (University of Bristol).

* Example project demonstrating the Re-Mote functionality
*
* - Boot sequence: LEDs flashing (Red, then yellow, finally green)
*
* - etimer/clock : Every LOOP_INTERVAL clock ticks (LOOP_PERIOD secs) the LED
* defined as LEDS_PERIODIC will turn on
* - rtimer : Exactly LEDS_OFF_HYSTERISIS rtimer ticks later,
* LEDS_PERIODIC will turn back off
* - ADC sensors : On-chip VDD / 3, temperature, and Phidget sensor
* values are printed over UART periodically.
* - UART : Every LOOP_INTERVAL the Remote 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_USER sends a rime broadcast. Reception of a rime
* packet will toggle LEDs defined as LEDS_RF_RX
* - Button : Keeping the button pressed will print a counter that
* increments every BUTTON_PRESS_EVENT_INTERVAL ticks
* - TMP102 : Built-in digital temperature sensor, every LOOP_INTERVAL
* clock ticks a sensor reading will be taken
