环境：keil5.20 STM32F407ZGT6 LCD(320*240) STemwin:STemWin_Library_V1.1.2
准备：
STemWIn在裸机上的移植，需要准备STemwin的库（ STemwin:STemWin_Library_V1.1.2.rar 链接：https://pan.baidu.com/s/1ekMm-X7RG5JK185GnV9fFw
提取码：peup ），LCD的空工程（带有LCD画点，读点函数）。
开始移植
第一步：解压STemWin_Library_V1.1.2.rar,目录结构如下
打开目录STemWin_Library_V1.1.2LibrariesSTemWinLibrary522，复制Config,inc,OS,LIB四个目录到工程文件夹中
删除Config中LCDConf_Lin_Template.c，LCDConf_Lin_Template.h文件。
根据需要保留LIB中文件，删除其他文件。此处使用CM4内核的F407，Keil IDE,保留STemWin522_CM4_Keil.lib。
根据是否使用OS，保留OS文件夹中相应文件。此处不使用OS，保留GUI_X.c。
将留下的文件添加进工程，并包含头文件路径。
留下的文件如图所示。
第二步，修改部分文件，
修改GUIConf.c 修改分配给GUI的内存大小，此处为16K
1 // Define the available number of bytes available for the GUI 2 #define GUI_NUMBYTES 0x4000 //16KB 2018/04/15-17:52:54 By Nick
修改GUIConf.h 配置GUI相关功能
1 #ifndef GUICONF_H 2 #define GUICONF_H 3 4 //Multi layer/display support 5 #define GUI_NUM_LAYERS 2 // Maximum number of available layers 6 7 //Multi tasking support 8 #ifdef OS_SUPPORT 9 #define GUI_OS (1) // Compile with multitasking support 10 #else 11 #define GUI_OS (0) 12 #endif 13 14 //Configuration of touch suppor 15 #ifndef GUI_SUPPORT_TOUCH 16 #define GUI_SUPPORT_TOUCH (1) // Support touchscreen 17 #endif 18 19 //Default font 20 #define GUI_DEFAULT_FONT &GUI_Font6x8 21 22 //Configuration of available packages 23 #define GUI_SUPPORT_MOUSE (1) /* Support a mouse */ 24 #define GUI_WINSUPPORT (1) /* Use window manager */ 25 #define GUI_SUPPORT_MEMDEV (1) /* Memory device package available */ 26 #define GUI_SUPPORT_DEVICES (1) /* Enable use of device pointers */ 27 28 #endif /* Avoid multiple inclusion */
修改GUIDRV_Template.c 修改画点和读点函数，注意要引入自己的LCD头文件
1 /********************************************************************* 2 * 3 * _SetPixelIndex 4 * 5 * Purpose: 6 * Sets the index of the given pixel. The upper layers 7 * calling this routine make sure that the coordinates are in range, so 8 * that no check on the parameters needs to be performed. 9 */ 10 static void _SetPixelIndex(GUI_DEVICE * pDevice, int x, int y, int PixelIndex) { 11 // 12 // Convert logical into physical coordinates (Dep. on LCDConf.h) 13 // 14 #if (LCD_MIRROR_X == 1) || (LCD_MIRROR_Y == 1) || (LCD_SWAP_XY == 1) 15 int xPhys, yPhys; 16 17 xPhys = LOG2PHYS_X(x, y); 18 yPhys = LOG2PHYS_Y(x, y); 19 #else 20 #define xPhys x 21 #define yPhys y 22 #endif 23 GUI_USE_PARA(pDevice); 24 GUI_USE_PARA(x); 25 GUI_USE_PARA(y); 26 GUI_USE_PARA(PixelIndex); 27 { 28 lcd_drawpoint(xPhys,yPhys,PixelIndex); //2018/04/15-18:47:44 By Nick 29 } 30 #if (LCD_MIRROR_X == 0) && (LCD_MIRROR_Y == 0) && (LCD_SWAP_XY == 0) 31 #undef xPhys 32 #undef yPhys 33 #endif 34 } 35 36 /********************************************************************* 37 * 38 * _GetPixelIndex 39 * 40 * Purpose: 41 * Returns the index of the given pixel. The upper layers 42 * calling this routine make sure that the coordinates are in range, so 43 * that no check on the parameters needs to be performed. 44 */ 45 static unsigned int _GetPixelIndex(GUI_DEVICE * pDevice, int x, int y) { 46 unsigned int PixelIndex; 47 // 48 // Convert logical into physical coordinates (Dep. on LCDConf.h) 49 // 50 #if (LCD_MIRROR_X == 1) || (LCD_MIRROR_Y == 1) || (LCD_SWAP_XY == 1) 51 int xPhys, yPhys; 52 53 xPhys = LOG2PHYS_X(x, y); 54 yPhys = LOG2PHYS_Y(x, y); 55 #else 56 #define xPhys x 57 #define yPhys y 58 #endif 59 GUI_USE_PARA(pDevice); 60 GUI_USE_PARA(x); 61 GUI_USE_PARA(y); 62 { 63 PixelIndex = lcd_read_gram(xPhys,yPhys); //2018/04/15-18:47:29 By Nick 64 } 65 #if (LCD_MIRROR_X == 0) && (LCD_MIRROR_Y == 0) && (LCD_SWAP_XY == 0) 66 #undef xPhys 67 #undef yPhys 68 #endif 69 return PixelIndex; 70 }
修改 GUIDRV_FlexColor.c文件 配置屏幕尺寸（此处为320*240）,可以用宏，Nick在此不用宏的原因是方便LCD初始化函数自动识别屏幕后，传递给GUI
1 #include "Nick_lcd.h" 2 #include "GUI.h" 3 #include "GUIDRV_FlexColor.h" 4 5 6 u16 XSIZE_PHYS,YSIZE_PHYS,VXSIZE_PHYS,VYSIZE_PHYS; //2018/04/15-18:48:10 By Nick 7 8 #ifndef GUICC_565 9 #error Color conversion not defined! 10 #endif 11 #ifndef GUIDRV_FLEXCOLOR 12 #error No display driver defined! 13 #endif 14 15 void LCD_X_Config(void) { //2018/04/15-18:48:24 By Nick 16 // Physical display size 17 XSIZE_PHYS = lcddev.width;// To be adapted to x-screen size 240 18 YSIZE_PHYS = lcddev.height; // To be adapted to y-screen size 320 19 VXSIZE_PHYS = XSIZE_PHYS; 20 VYSIZE_PHYS = YSIZE_PHYS; 21 GUI_DEVICE_CreateAndLink(&GUIDRV_Template_API,GUICC_M565,0,0); 22 LCD_SetSizeEx(0,XSIZE_PHYS,YSIZE_PHYS); 23 LCD_SetVSizeEx(0,VXSIZE_PHYS,VYSIZE_PHYS); 24 } 25 26 27 int LCD_X_DisplayDriver(unsigned LayerIndex, unsigned Cmd, void * pData) { 28 int r; 29 (void) LayerIndex; 30 (void) pData; 31 32 switch (Cmd) { 33 case LCD_X_INITCONTROLLER: { 34 return 0; 35 } 36 default: 37 r = -1; 38 } 39 return r; 40 }
在此，修改已完成。
第三步，编写测试程序。
#include "stm32f4xx_conf.h" #include "GUI.h" #include "Nick_lcd.h" int main(void) { lcd_init(0); //LCD初始化 RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_CRC,ENABLE);//使能CRC时钟，否则STemWin不能使用 GUI_Init(); GUI_SetColor(GUI_RED); GUI_SetBkColor(GUI_BLUE); GUI_SetFont(&GUI_Font24_ASCII); GUI_Clear(); GUI_DispStringAt("Hello World",10,10); }
到此可以看到现象。如图
当然，到此STemwin移植就结束了。下一篇将添加触摸屏点击功能。
