環(huán)境：

主機(jī):WIN8

開發(fā)環(huán)境:MDK5.13

emwin版本：STemWinLibrary522

mcu: stm32f407VGT6

開發(fā)板：安富萊STM32-X3

TFT型號：艾藍(lán)2.8寸TFT，主控芯片：ILI9325

說明:

在STM32F407上移植emwin，驅(qū)動屏幕接口為FSMC

移植步驟：

1.MDK新建文件結(jié)構(gòu)：

2.GUIConf.c文件修改

a)增加宏定義：

#defineGUI_NUMBYTES(1024*80)

#defineGUI_BLOCKSIZE0x80

b)GUI_X_Config(void)函數(shù)中增加語句：

GUI_ALLOC_SetAvBlockSize(GUI_BLOCKSIZE);

修改后：

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

*

*GUI_X_Config

*

*Purpose:

*Calledduringtheinitializationprocessinordertosetupthe

*availablememoryfortheGUI.

*/

voidGUI_X_Config(void){

//

//32bitalignedmemoryarea

//

staticU32aMemory[GUI_NUMBYTES/4];

//

//AssignmemorytoemWin

//

GUI_ALLOC_AssignMemory(aMemory,GUI_NUMBYTES);

GUI_ALLOC_SetAvBlockSize(GUI_BLOCKSIZE);

//

//Setdefaultfont

//

GUI_SetDefaultFont(GUI_FONT_6X8);

}

3.LCDConf_FlexColor_Template.c文件修改

a)增加宏定義:

#defineLCD_REG_ADDRESSBANK1_LCD_REG

#defineLCD_DATA_ADDRESSBANK1_LCD_RAM

這兩個(gè)BANK宏定義在tft驅(qū)動文件中定義：

#defineBANK1_BASE((uint32_t)(0x60000000|0x00000000))

#defineBANK1_LCD_RAM*(__IOuint16_t*)(BANK1_BASE+(1<<(18+1)))/*FSMC16位總線模式下，F(xiàn)SMC_A18口線對應(yīng)物理地址A19*/

#defineBANK1_LCD_REG*(__IOuint16_t*)(BANK1_BASE)

具體值和接線相關(guān)

b)具體函數(shù)修改

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

*

*Localfunctions

*

**********************************************************************

*/

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

*

*LcdWriteReg

*

*Functiondescription:

*Setsdisplayregister

*/

staticvoidLcdWriteReg(U16Data){

//...TBDbyuser

LCD_REG_ADDRESS=Data;

}

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

*

*LcdWriteData

*

*Functiondescription:

*Writesavaluetoadisplayregister

*/

staticvoidLcdWriteData(U16Data){

//...TBDbyuser

LCD_DATA_ADDRESS=Data;

}

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

*

*LcdWriteDataMultiple

*

*Functiondescription:

*Writesmultiplevaluestoadisplayregister.

*/

staticvoidLcdWriteDataMultiple(U16*pData,intNumItems){

while(NumItems--){

//...TBDbyuser

LCD_DATA_ADDRESS=*pData++;

}

}

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

*

*LcdReadDataMultiple

*

*Functiondescription:

*Readsmultiplevaluesfromadisplayregister.

*/

staticvoidLcdReadDataMultiple(U16*pData,intNumItems){

while(NumItems--){

//...TBDbyuser

*pData++=LCD_DATA_ADDRESS;

}

}

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

*

*Publicfunctions

*

**********************************************************************

*/

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

*

*LCD_X_Config

*

*Functiondescription:

*Calledduringtheinitializationprocessinordertosetupthe

*displaydriverconfiguration.

*

*/

voidLCD_X_Config(void){

GUI_DEVICE*pDevice;

CONFIG_FLEXCOLORConfig={0};

GUI_PORT_APIPortAPI={0};

//

//Setdisplaydriverandcolorconversion

//

pDevice=GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR,GUICC_565,0,0);

//

//Displaydriverconfiguration,requiredforLin-driver

//

LCD_SetSizeEx(0,XSIZE_PHYS,YSIZE_PHYS);

LCD_SetVSizeEx(0,VXSIZE_PHYS,VYSIZE_PHYS);

//

//Orientation

//

//Config.Orientation=GUI_SWAP_XY|GUI_MIRROR_Y;

Config.FirstCOM=0;

Config.FirstSEG=0;

//Config.Orientation=GUI_MIRROR_X|GUI_MIRROR_Y;

Config.NumDummyReads=2;

GUIDRV_FlexColor_Config(pDevice,&Config);

//

//Setcontrollerandoperationmode

//

PortAPI.pfWrite16_A0=LcdWriteReg;

PortAPI.pfWrite16_A1=LcdWriteData;

PortAPI.pfWriteM16_A1=LcdWriteDataMultiple;

PortAPI.pfReadM16_A1=LcdReadDataMultiple;

GUIDRV_FlexColor_SetFunc(pDevice,&PortAPI,GUIDRV_FLEXCOLOR_F66708,GUIDRV_FLEXCOLOR_M16C0B16);

//GUIDRV_FlexColor_SetFunc(pDevice,&PortAPI,GUIDRV_FLEXCOLOR_F66709,GUIDRV_FLEXCOLOR_M16C0B16);

}

其中：GUIDRV_FlexColor_SetFunc函數(shù)說明：

因?yàn)橹骺匦酒瑸镮LI9325,所以參數(shù)選擇GUIDRV_FLEXCOLOR_F66708

4.GUI_X.c文件修改

此文件控制的是GUI中的延時(shí)，可以用定時(shí)器配合實(shí)現(xiàn)，修改如下：

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

*

*Globaldata

*/

volatileGUI_TIMER_TIMEOS_TimeMS;

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

*

*Timing:

*GUI_X_GetTime()

*GUI_X_Delay(int)

SometimingdependentroutinesrequireaGetTime

anddelayfunction.Defaulttimeunit(tick),normallyis

1ms.

*/

extern__IOint32_tg_iRunTime;

GUI_TIMER_TIMEGUI_X_GetTime(void){

//returnOS_TimeMS;

returng_iRunTime;

}
