使用KP236和PIC32MZ1024EFH064在各种环境中实现精确且一致的高度数据

/*!
 * @file main.c
 * @brief Altitude5 Click example
 *
 * # Description
 * This library contains API for Altitude 5 Click driver.
 * The demo application reads ADC value, calculate pressure and altitude.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes I2C or analog driver and log UART.
 * After driver initialization the app set default settings.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the Altitude 5 Click board™.
 * In this example, we read ADC values and 
 * display the Pressure ( mBar ) and Altitude ( m ) data.
 * Results are being sent to the Usart Terminal where you can track their changes.
