使用SM9336-BCE-S-250-000和PIC18LF47K42体验压力测量的新标准

/*!
 * @file main.c
 * @brief Diff Press 4 Click example
 *
 * # Description
 * This example demonstrates the use of Diff Press 4 Click board™ 
 * by reading and displaying the differential pressure and sensor temperature measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The demo application reads and displays the Differential Pressure [Pa] 
 * and sensor Temperature [degree Celsius] data measurements.
 * Results are being sent to the UART Terminal, where you can track their changes.
