How To use this driver: + -------------------------- + - This driver is used to drive directly an LCD TFT using the LTDC controller. + - This driver uses timing and setting for RK043FN48H LCD. + + 2. Driver description: + --------------------- + + Initialization steps: + o Initialize the LCD using the BSP_LCD_Init() function. + o Apply the Layer configuration using the BSP_LCD_LayerDefaultInit() function. + o Select the LCD layer to be used using the BSP_LCD_SelectLayer() function. + o Enable the LCD display using the BSP_LCD_DisplayOn() function. + + + Options + o Configure and enable the color keying functionality using the + BSP_LCD_SetColorKeying() function. + o Modify in the fly the transparency and/or the frame buffer address + using the following functions: + - BSP_LCD_SetTransparency() + - BSP_LCD_SetLayerAddress() + + + Display on LCD + o Clear the hole LCD using BSP_LCD_Clear() function or only one specified string + line using the BSP_LCD_ClearStringLine() function. + o Display a character on the specified line and column using the BSP_LCD_DisplayChar() + function or a complete string line using the BSP_LCD_DisplayStringAtLine() function. + o Display a string line on the specified position (x,y in pixel) and align mode + using the BSP_LCD_DisplayStringAtLine() function. + o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap) + on LCD using the available set of functions. + @endverbatim + ****************************************************************************** + * @attention + * + * <h2><center>© COPYRIGHT(c) 2015 STMicroelectronics</center></h2> + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * 1.
