 * \defgroup zoul-adc-sensors Zoul adc wrapper to use analogue sensors
 *
 * The ADC wrapper implement analogue sensors on top of the ADC interface,
 * obscuring the ADC configuration and required calculations to obtain actual
 * sensor values.  The driver allows to reuse the adc-wrapper implementation and
 * add sensors easily, without duplicating code, providing also a simplified
 * interface and exposing the available ADC assigned channels by a given
 * platform.
 *
 * To use a given sensor simply use: adc_sensors.configure(SENSOR_NAME, pin_no),
 * where pin_no is a given pin in the PA port, check out the board.h for more
 * information on available pins.  To read a value just use
 * adc_sensors.value(SENSOR_NAME), the expected result would be the sensor value
 * already converted to the sensor variable type, check the adc-wrapper file
 * for more information.
