环境：

主机:WIN8

开发环境:MDK5.13

emwin版本：STemWinLibrary522

mcu: stm32f407VGT6

开发板：安富莱STM32-X3

TFT型号：艾蓝2.8寸TFT，主控芯片：ILI9325

说明:

在STM32F407上移植emwin，驱动屏幕接口为FSMC

移植步骤：

1.MDK新建文件结构：

2.GUIConf.c文件修改

a)增加宏定义：

#define GUI_NUMBYTES (1024 * 80)
#define GUI_BLOCKSIZE 0x80

b)GUI_X_Config(void)函数中增加语句：

GUI_ALLOC_SetAvBlockSize(GUI_BLOCKSIZE);

修改后：

[cpp] view plain copy

<code class="language-cpp">/*********************************************************************
*
* GUI_X_Config
*
* Purpose:
* Called during the initialization process in order to set up the
* available memory for the GUI.
*/
void GUI_X_Config(void) {
//
// 32 bit aligned memory area
//
static U32 aMemory[GUI_NUMBYTES / 4];
//
// Assign memory to emWin
//
GUI_ALLOC_AssignMemory(aMemory, GUI_NUMBYTES);
GUI_ALLOC_SetAvBlockSize(GUI_BLOCKSIZE);
//
// Set default font
//
GUI_SetDefaultFont(GUI_FONT_6X8);
}</code>

3.LCDConf_FlexColor_Template.c文件修改

a)增加宏定义:

#define LCD_REG_ADDRESS BANK1_LCD_REG
#define LCD_DATA_ADDRESS BANK1_LCD_RAM

这两个BANK宏定义在tft驱动文件中定义：

#define BANK1_BASE ((uint32_t)(0x60000000 | 0x00000000))
#define BANK1_LCD_RAM *(__IO uint16_t *)(BANK1_BASE + (1 << (18 + 1))) /* FSMC 16位总线模式下，FSMC_A18口线对应物理地址A19 */
#define BANK1_LCD_REG *(__IO uint16_t *)(BANK1_BASE)

具体值和接线相关

b)具体函数修改

/*********************************************************************
*
* Local functions
*

/********************************************************************
*
* LcdWriteReg
*
* Function description:
* Sets display register

// ... TBD by user
LCD_REG_ADDRESS = Data;
}
/********************************************************************
*
* LcdWriteData
*
* Function description:
* Writes a value to a display register
*/
static void LcdWriteData(U16 Data) {
// ... TBD by user
LCD_DATA_ADDRESS=Data;
}
/********************************************************************
*
* LcdWriteDataMultiple
*
* Function description:
* Writes multiple values to a display register.
*/
static void LcdWriteDataMultiple(U16 * pData, int NumItems) {
while (NumItems--) {
// ... TBD by user
LCD_DATA_ADDRESS=*pData++;
}
}
/********************************************************************
*
* LcdReadDataMultiple
*
* Function description:

*/
static void LcdReadDataMultiple(U16 * pData, int NumItems) {
while (NumItems--) {
// ... TBD by user
*pData++=LCD_DATA_ADDRESS;
}
}

/*********************************************************************

*/
