使用 820M1-0025 和 STM32F031K6 体验运动感应的新时代

/*!
 * @file main.c
 * @brief PiezoAccel Click example
 *
 * # Description
 * This application demonstrates the performance
 * of Piezo Accel click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of UART LOG and SPI click drivers.
 * Additionally, a default config is performed for
 * "out of the box" Piezo Accel click settings.
 * Calibration is optional and is used to correct
 * the power supply offset of the sensor.
 *
 * ## Application Task
 * The ADC is constantly read and converted to a
 * g-force acceleration unit. Data is sent via LOG
 * every 20 ms and works on MikroPlot for graphical
 * representation of the sensor results.
 *
 * *note:*
 * This demo app is intended to be used with MikroPlot data
 * visualization tool for clear understanding of the results.
