 * \brief GainAmp2 Click example
 * 
 * # Description
 * This application is programmable gain amplifier
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes and sets GainAMP 2 Click channel 0 to amplify the signal 2 times
 * 
 * ## Application Task  
 * Displays the voltage measured from VOUT pin
