DL3LD 1:1556bcaaf759 3 * @file stm32746g_discovery_lcd.c
DL3LD 1:1556bcaaf759 4 * @author MCD Application Team
DL3LD 1:1556bcaaf759 5 * @version V1.0.0
DL3LD 1:1556bcaaf759 6 * @date 25-June-2015
DL3LD 1:1556bcaaf759 7 * @brief This file includes the driver for Liquid Crystal Display (LCD) module
DL3LD 1:1556bcaaf759 8 * mounted on STM32746G-Discovery board.
DL3LD 1:1556bcaaf759 9 @verbatim
DL3LD 1:1556bcaaf759 10 1. How To use this driver:
DL3LD 1:1556bcaaf759 11 --------------------------
DL3LD 1:1556bcaaf759 12 - This driver is used to drive directly an LCD TFT using the LTDC controller.
DL3LD 1:1556bcaaf759 13 - This driver uses timing and setting for RK043FN48H LCD.
DL3LD 1:1556bcaaf759 14
DL3LD 1:1556bcaaf759 15 2. Driver description:
DL3LD 1:1556bcaaf759 16 ---------------------
DL3LD 1:1556bcaaf759 17 + Initialization steps:
DL3LD 1:1556bcaaf759 18 o Initialize the LCD using the BSP_LCD_Init() function.
DL3LD 1:1556bcaaf759 19 o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function.
DL3LD 1:1556bcaaf759 20 o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
DL3LD 1:1556bcaaf759 21 o Enable the LCD display using the BSP_LCD_DisplayOn() function.
DL3LD 1:1556bcaaf759 22
DL3LD 1:1556bcaaf759 23 + Options
DL3LD 1:1556bcaaf759 24 o Configure and enable the color keying functionality using the
DL3LD 1:1556bcaaf759 25 BSP_LCD_SetColorKeying() function.
DL3LD 1:1556bcaaf759 26 o Modify in the fly the transparency and/or the frame buffer address
DL3LD 1:1556bcaaf759 27 using the following functions:
DL3LD 1:1556bcaaf759 28 - BSP_LCD_SetTransparency()
DL3LD 1:1556bcaaf759 29 - BSP_LCD_SetLayerAddress()
DL3LD 1:1556bcaaf759 30
DL3LD 1:1556bcaaf759 31 + Display on LCD
DL3LD 1:1556bcaaf759 32 o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
DL3LD 1:1556bcaaf759 33 line using the BSP_LCD_ClearStringLine() function.
DL3LD 1:1556bcaaf759 34 o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
DL3LD 1:1556bcaaf759 35 function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
DL3LD 1:1556bcaaf759 36 o Display a string line on the specified position (x,y in pixel) and align mode
DL3LD 1:1556bcaaf759 37 using the BSP_LCD_DisplayStringAtLine() function.
DL3LD 1:1556bcaaf759 38 o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
DL3LD 1:1556bcaaf759 39 on LCD using the available set of functions.
