关于2410上LCD移植方面的几点总结(含触摸屏)=LCD部分=分辨率修改1、s2410.h (D:WINCE500PLATFORMSMDK2410INC)#define LCD_XSIZE_TFT (640)#define LCD_YSIZE_TFT (480) 修改为#define LCD_XSIZE_TFT (240)#define LCD_YSIZE_TFT (320)修改时序 （可选的范围很宽，很多时候可以不做修改）1、cfw.c (D:WINCE500PLATFORMSMDK2410KERNELHAL)修改函数 InitDisplay（）LCD显示 竖屏改为横屏（不需要修改s2410.h和cfw.c中的任何内容）1、SMDK2440DRIVERSDISPLAYS3C2440LCD 目录下的sources文件合适位置增加：CLEARTYPE=02、s3c2440disp.h文件头上加一句#define ROTATE3、s3c2440disp.cpp中 S3C2440DISP:S3C2440DISP (void)加上#ifdef ROTATEm_iRotate = DMDO_90;SetRotateParms();#endif4、注册表文件wince420platformsmdk2410filesplatform.reg中添加如下键值：HKEY_LOCAL_MACHINESystemGDIROTATION“Angle”=dword:5A“LandscapeMode”=dword:15、修改函数DrvEscape()和DynRotate() ULONG S3C2410DISP:DrvEscape(SURFOBJ *pso,ULONG iEsc,ULONG cjIn,PVOID pvIn,ULONG cjOut,PVOID pvOut)#ifdef ROTATEif (iEsc = DRVESC_GETGAMMAVALUE)return GetGammaValue(ULONG *)pvOut);else if (iEsc = DRVESC_SETGAMMAVALUE)return SetGammaValue(cjIn, *(BOOL *)pvIn); if (iEsc = DRVESC_GETSCREENROTATION)*(int *)pvOut = (DMDO_0 | DMDO_90 | DMDO_180 | DMDO_270) width = m_nScreenWidth;m_pMode-height = m_nScreenHeight;pSurf-SetRotation(m_nScreenWidth, m_nScreenHeight, angle);return DISP_CHANGE_SUCCESSFUL;=触摸屏部分=关于x或者y轴对称tchpdd.cpp（D:WINCE500PLATFORMSMDK2410DRIVERSTOUCHP） #defineINVERSE_X #defineINVERSE_Y 注：体现在函数Touch_CoordinateConversion（）中 #ifdef INVERSE_X*px = TOUCH_X*4 - 1 - *px;#endif#ifdefINVERSE_Y*py = TOUCH_Y*4 - 1 - *py;#endifx 和y 的坐标的对调tchpdd.cpp（D:WINCE500PLATFORMSMDK2410DRIVERSTOUCHP）函数Touch_CoordinateConversion（）中 #if 1 / x y坐标对调temp = *px;*px = *py;*py = temp;#endif大小移植不一样（例如640*480的bsp要跑在320*240的LCD+触摸屏上）修改 #define LCD_TYPETFT240_320体现在#if ( LCD_TYPE = TFT640_480 )#define TOUCH_MAX_X 1000#define TOUCH_MIN_X 30#define TOUCH_MAX_Y 980#define TOUCH_MIN_Y 30#define TOUCH_X640#define TOUCH_Y480#else #define TOUCH_MAX_X 922/922/955 /950#define TOUCH_MIN_X 75/75/100 /90#define TOUCH_MAX_Y 940/940/925 /960#define TOUCH_MIN_Y 40/40/70 /50#define TOUCH_X240#define TOUCH_Y320#endif修改注册表 （特别重要，千万别忽视，否则触摸屏变化一点规律也没有，找问题还真难）platform.reg（D:WINCE500PLATFORMSMDK2410FILES）修改HKEY_LOCAL_MACHINEHARDWAREDEVICEMAPTOUCHMaxCalError=dword:7; portrait CalibrationData=1267,927 239,1679 251,143 2311,143 2311,1691; CESYSGEN ENDIF CE_MODULES_POINTER ; CESYSGEN IF CE_MODULES_DISPLAY为HKEY_LOCAL_MACHINEHARDWAREDEVICEMAPTOUCHMaxCalError=dword:7; portrait ; Calibr
