GUI

Добавление STemWin в проект.

1 - из папки STemWin_Library_V1.2.0  ->   Library   ->   STemWinLibrary532  добавить файл              библиотеки      STemWin532_CM4_Keil.lib                   для проекта без RTOS
                               STemWin532_CM4_OS_Keil.lib            для RTOS

2 - из папки STemWin_Library_V1.2.0  ->   Library   ->   STemWinLibrary532  -> inc  добавить            все заголовочные h файлы. с прототипами функций из lib файла

- из папки STemWin_Library_V1.2.0  ->   Library   ->   STemWinLibrary532  -> Config добавить
     файлы конфигурации GUI
                   GUIConf.c
                   GUIConf.h
     и дисплея
     для дисплеев без контроллера LTDC (RGB)
                   LCDConf_Lin_Template.c
                   LCDConf_Lin_Template.h
     для дисплеев с контроллером
                   LCDConf_FlexColor_Template.c
                   LCDConf_FlexColor_Templateh

- из папки STemWin_Library_V1.2.0  ->   Library   ->   STemWinLibrary532  -> OS добавить
                   GUI_X.c                   для проекта без RTOS
                   GUI_X_OS.c            для RTOS

Для Keil библиотека emWin находится в папке
Keil -> ARM -> PACK -> Keil-Middleware  -> 7.4.0 -> emWin

The function GUI_Init() calls the functions (please make sure those functions to not cause the hard fault)

1 - GUI_X_Config()
2 - LCD_X_Config()
3 - LCD_X_DisplayDriver() -  которая вызывает при первом обращении процедуру настройки и инициализации дисплея
4 - GUI_X_Init
