How To use this driver: -------------------------- - This driver is used to drive indirectly an LCD TFT. - This driver supports the AM-240320LDTNQW00H (SPFD5408D) and AM240320LGTNQW00H (HX8347D) LCD mounted on MB895 daughter board - The SPFD5408D and HX8347D components driver MUST be included with this driver. 2. Driver description: --------------------- + Initialization steps: o Initialize the LCD using the LCD_Init() function. + Display on LCD o Clear the hole LCD using yhe LCD_Clear() function or only one specified string line using the LCD_ClearStringLine() function. o Display a character on the specified line and column using the LCD_DisplayChar() function or a complete string line using the LCD_DisplayStringAtLine() function. o Display a string line on the specified position (x,y in pixel) and align mode using the LCD_DisplayStringAtLine() function. o Draw and fill a basic shapes (dot, line, rectangle, circle, ellipse, .. bitmap) on LCD using a set of functions. ------------------------------------------------------------------------------*/ /* Includes ------------------------------------------------------------------*/ #include "stm32072b_eval_lcd.h" #include "../../../Utilities/Fonts/fonts.h" #include "../../../Utilities/Fonts/font24.c" #include "../../../Utilities/Fonts/font20.c" #include "../../../Utilities/Fonts/font16.c" #include "../../../Utilities/Fonts/font12.c" #include "../../../Utilities/Fonts/font8.c" /** @addtogroup BSP * @{ */ /** @addtogroup STM32072B_EVAL * @{ */ /** @addtogroup STM32072B_EVAL_LCD * @{ */ /** @defgroup STM32072B_EVAL_LCD_Private_Constants Private Constants * @{ */ #define POLY_X(Z) ((int32_t)((pPoints + (Z))->X)) #define POLY_Y(Z) ((int32_t)((pPoints + (Z))->Y)) #define MAX_HEIGHT_FONT 17 #define MAX_WIDTH_FONT 24 #define OFFSET_BITMAP 54 /** * @} */ /** @defgroup STM32072B_EVAL_LCD_Private_Macros Private Macros * @{ */ #define ABS(X) ((X) > 0 ?
