icis4 0:098e992daf30 4 * @author MCD Application Team

icis4 0:098e992daf30 7 * @brief This file provides all the LCD Log firmware functions.
icis4 0:098e992daf30 8 *
icis4 0:098e992daf30 9 * The LCD Log module allows to automatically set a header and footer
icis4 0:098e992daf30 10 * on any application using the LCD display and allows to dump user,
icis4 0:098e992daf30 11 * debug and error messages by using the following macros: LCD_ErrLog(),
icis4 0:098e992daf30 12 * LCD_UsrLog() and LCD_DbgLog().
icis4 0:098e992daf30 13 *
icis4 0:098e992daf30 14 * It supports also the scroll feature by embedding an internal software
icis4 0:098e992daf30 15 * cache for display. This feature allows to dump message sequentially
icis4 0:098e992daf30 16 * on the display even if the number of displayed lines is bigger than
icis4 0:098e992daf30 17 * the total number of line allowed by the display.
