bcostm 0:c9112f0c67e3 6 * @date 25-June-2015
bcostm 0:c9112f0c67e3 7 * @brief This file includes the driver for Liquid Crystal Display (LCD) module
bcostm 0:c9112f0c67e3 8 * mounted on STM32746G-Discovery board.

bcostm 0:c9112f0c67e3 10 1. How To use this driver:
bcostm 0:c9112f0c67e3 11 --------------------------
bcostm 0:c9112f0c67e3 12 - This driver is used to drive directly an LCD TFT using the LTDC controller.
bcostm 0:c9112f0c67e3 13 - This driver uses timing and setting for RK043FN48H LCD.
bcostm 0:c9112f0c67e3 14
bcostm 0:c9112f0c67e3 15 2. Driver description:
bcostm 0:c9112f0c67e3 16 ---------------------
bcostm 0:c9112f0c67e3 17 + Initialization steps:
bcostm 0:c9112f0c67e3 18 o Initialize the LCD using the BSP_LCD_Init() function.
bcostm 0:c9112f0c67e3 19 o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function.
bcostm 0:c9112f0c67e3 20 o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function.
bcostm 0:c9112f0c67e3 21 o Enable the LCD display using the BSP_LCD_DisplayOn() function.
bcostm 0:c9112f0c67e3 22
bcostm 0:c9112f0c67e3 23 + Options
bcostm 0:c9112f0c67e3 24 o Configure and enable the color keying functionality using the
bcostm 0:c9112f0c67e3 25 BSP_LCD_SetColorKeying() function.
bcostm 0:c9112f0c67e3 26 o Modify in the fly the transparency and/or the frame buffer address
bcostm 0:c9112f0c67e3 27 using the following functions:
bcostm 0:c9112f0c67e3 28 - BSP_LCD_SetTransparency()
bcostm 0:c9112f0c67e3 29 - BSP_LCD_SetLayerAddress()
bcostm 0:c9112f0c67e3 30
bcostm 0:c9112f0c67e3 31 + Display on LCD
bcostm 0:c9112f0c67e3 32 o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string
bcostm 0:c9112f0c67e3 33 line using the BSP_LCD_ClearStringLine() function.
bcostm 0:c9112f0c67e3 34 o Display a character on the specified line and column using the BSP_LCD_DisplayChar()
bcostm 0:c9112f0c67e3 35 function or a complete string line using the BSP_LCD_DisplayStringAtLine() function.
bcostm 0:c9112f0c67e3 36 o Display a string line on the specified position (x,y in pixel) and align mode
bcostm 0:c9112f0c67e3 37 using the BSP_LCD_DisplayStringAtLine() function.
bcostm 0:c9112f0c67e3 38 o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap)
bcostm 0:c9112f0c67e3 39 on LCD using the available set of functions.
