 * \brief CapWheel Click example
 * 
 * # Description
 * This application is use for controling various devices.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes I2C interface, performs the device reset and
 * activates the desired channels (from CH0 to CH9), in this example all channels are activated.
 * 
 * ## Application Task  
 * Checks is sense data ready for reading and if was ready, 
  then reads wheel coordinates and sends these results to the LEDs.
