使用 FS102A-0000-3000-G 和 STM32G071RB 实现高达 3000 克的压缩负载检测

/*!
 * @file main.c
 * @brief Force Cell Click Example.
 *
 * # Description
 * This example demonstrates the use of the Force Cell Click board by reading the applied force
 * in newtons (N) from a load cell sensor. The application initializes the driver, calibrates the
 * offset, and continuously measures and logs the force value to the USB UART terminal.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the logger and the Click driver, performs offset calibration to null the load cell.
 *
 * ## Application Task
 * Continuously reads and displays the current force value in newtons every 100ms.
