使用STM32F031K6和TLC5926改善数据表示

/*!
 * @file main.c
 * @brief AlphaNumG Click example
 *
 * # Description
 * This example showcases the initialization and configuration of the logger and Click modules
 * and shows how to display characters and numbers on both LED segments of the Click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and Click modules.
 * 
 * ## Application Task  
 * This function sets the time interval at which the symbols are displayed on the LED 
 * segments and shows a few characters and numbers.
