+ ******************************************************************************
+ * @file lcd_log.c
+ * @author MCD Application Team
+ * @version V5.0.2
+ * @date 05-March-2012
+ * @brief This file provides all the LCD Log firmware functions.
+ *
+ * The LCD Log module allows to automatically set a header and footer
+ * on any application using the LCD display and allows to dump user,
+ * debug and error messages by using the following macros: LCD_ErrLog(),
+ * LCD_UsrLog() and LCD_DbgLog().
+ *
+ * It supports also the scroll feature by embedding an internal software
+ * cache for display. This feature allows to dump message sequentially
+ * on the display even if the number of displayed lines is bigger than
+ * the total number of line allowed by the display.
