Upgrade your pressure monitoring game with 2513130810401 and PIC32MZ2048EFM100

/*!
 * @file main.c
 * @brief Diff Press 3 Click Example.
 *
 * # Description
 * This library contains API for the Diff Press 3 Click driver.
 * This demo application shows an example of 
 * differential pressure and temperature measurement.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C and ADC module and log UART.
 *
 * ## Application Task
 * This example demonstrates the use of the Diff Press 3 Click board™.
 * The demo application measures and display the Differential Pressure [kPa]
 * and Temperature [degree Celsius] data.
 * Results are being sent to the UART Terminal, where you can track their changes.
