 * @{
 *
 * \defgroup cc26xx-demo CC26xx Demo Project
 *
 *   Example project demonstrating the CC26xx platforms
 *
 *   This example will work for the following boards:
 *   - srf06-cc26xx: SmartRF06EB + CC26XX EM
 *   - sensortag-cc26xx: CC26XX sensortag
 *
 *   By default, the example will build for the srf06-cc26xx board. To switch
 *   between platforms:
 *   - make clean
 *   - make BOARD=sensortag-cc26xx savetarget
 *
 *     or
 *
 *     make BOARD=srf06-cc26xx savetarget
 *
 *   This is an IPv6/RPL-enabled example. Thus, if you have a border router in
 *   your installation (same RDC layer, same PAN ID and RF channel), you should
 *   be able to ping6 this demo node.
 *
 *   This example also demonstrates CC26xx BLE operation. The process starts
 *   the BLE beacon daemon (implemented in the RF driver). The daemon will
 *   send out a BLE beacon periodically. Use any BLE-enabled application (e.g.
 *   LightBlue on OS X or the TI BLE Multitool smartphone app) and after a few
 *   seconds the cc26xx device will be discovered.
 *
 * - etimer/clock : Every CC26XX_DEMO_LOOP_INTERVAL clock ticks the LED defined
 *                  as CC26XX_DEMO_LEDS_PERIODIC will toggle and the device
 *                  will print out readings from some supported sensors
 * - sensors      : Some sensortag sensors are read asynchronously (see sensor
 *                  documentation). For those, this example will print out
 *                  readings in a staggered fashion at a random interval
 * - Buttons      : CC26XX_DEMO_SENSOR_1 button will toggle CC26XX_DEMO_LEDS_BUTTON
 *                - CC26XX_DEMO_SENSOR_2 turns on LEDS_REBOOT and causes a
 *                  watchdog reboot
 *                - The remaining buttons will just print something
 *                - The example also shows how to retrieve the duration of a
 *                  button press (in ticks). The driver will generate a
 *                  sensors_changed event upon button release
 * - UART         : Receiving an entire line of text over UART (ending
 *                  in \\r) will cause CC26XX_DEMO_LEDS_SERIAL_IN to toggle
 *                  This also demonstrates how a code module can influence
 *                  low-power operation: In this example we keep the UART on
 *                  and capable to RX even with the chip in deep sleep.
 *                  see keep_uart_on() and the UART driver
 * - Reed Relay   : Will toggle the sensortag buzzer on/off
