 * \brief Pressure12 Click example
 * 
 * # Description
 * Reads ADC value, convert ADC data to Voltage[ mV ] and pressure [ mBar ].
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes ADC and LOG for logging data.
 * 
 * ## Application Task  
 * Reads ADC value, convert ADC data to Voltage[ mV ] on the AN pin and
 * convert to Pressure data in mBar. All data logs to the USBUART each second.
 *
 * ## NOTE
 * Output is proportional to the difference between applied pressure 
 * and atmospheric (ambient) pressure.
