我的显示

void LCD_X_Config(void)

{

       

        GUI_DEVICE * pDevice;

        GUI_PORT_API PortAPI = {0};

          CONFIG_FLEXCOLOR Config = {0};

        pDevice = GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_M565, 0, 0);

  LCD_SetSizeEx (0, XSIZE_PHYS,   YSIZE_PHYS);

  LCD_SetVSizeEx(0, VXSIZE_PHYS,  VYSIZE_PHYS);

        Config.Orientation = GUI_SWAP_XY ;

        GUIDRV_FlexColor_Config(pDevice, &Config);

        PortAPI.pfWrite16_A0  = LcdWriteReg;

        PortAPI.pfWrite16_A1  = LcdWriteData;

        PortAPI.pfWriteM16_A1 = LcdWriteDataMultiple;

        PortAPI.pfReadM16_A1  = LcdReadDataMultiple;

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

}
