 * 
 * # Description
 * This application collects data from the sensor, calculates the voltage to a
 * digital value and then logs it.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and sets configuration which enables channel 0,
 * puts AIN0 on positive analog input and AIN1 on negative analog input,
 * enables internal reference voltage (approximately 2.65V (AVDD = 3.3V)),
 * and also enables bipolar operation mode and puts device on full power mode.
 * When the ADC is configured for unipolar operation, the output code is natural
 * (straight) binary with a zero differential input voltage 
 * resulting in a code of 0x00000000, a midscale voltage resulting in a code 
 * of 0x00800000, and a full-scale input voltage resulting in a code of 0x00FFFFFF.
 * When the ADC is configured for bipolar operation, the output code is offset
 * binary with a negative full-scale voltage resulting in a code of 0x00000000, 
 * a zero differential input voltage resulting in a code of 0x00800000, 
 * and a positive full-scale input voltage resulting in a code of 0x00FFFFFF.
 * 
 * ## Application Task  
 * Gets 24-bit converted data in single read mode and logs data on USB UART.
 * Repeats operation every 500 ms.
