 * @brief Load Cell 7 Click example
 *
 * # Description
 * This example demonstrates the use of Load Cell 7 Click by measuring the weight
 * in grams of the goods from the load cell sensor connected to the Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and reads the tare scale of the empty container, and after
 * that, it calibrates the weight scale with a known calibration weight.
 *
 * ## Application Task
 * Reads the net weight of the goods in grams approximately once per second and logs the
 * results on the USB UART.
