RT-Thread的RT-GUI在神舟开发板上移植.doc

RT-Thread的RTGUI移植步骤 （1.10RC版本）一.写好液晶屏幕的 画点ssd1289_lcd_set_pixel, 获得点ssd1289_lcd_get_pixel, 画横线 ssd1289_lcd_draw_hline,/ 画竖线ssd1289_lcd_draw_vline, 原始水平线ssd1289_lcd_draw_raw_hline 以上函数的参数要参考rtgui_graphic_driver_ops结构体 液晶初始化函数ili9320_Initializtion(); 六个底层驱动函数二.准备好三个结构体1.结构体原型struct rtgui_graphic_driver_ops/* set and get pixel in (x, y) */void (*set_pixel) (rtgui_color_t *c, int x, int y);void (*get_pixel) (rtgui_color_t *c, int x, int y);void (*draw_hline)(rtgui_color_t *c, int x1, int x2, int y);void (*draw_vline)(rtgui_color_t *c, int x , int y1, int y2);/* draw raw hline */void (*draw_raw_hline)(rt_uint8_t *pixels, int x1, int x2, int y); 结构体使用例子struct rt_device_graphic_ops lcd_ili_ops = /图形驱动接口 ssd1289_lcd_set_pixel, /画点自己实现ssd1289_lcd_get_pixel, /获得点 自己实现ssd1289_lcd_draw_hline,/画横线 自己实现ssd1289_lcd_draw_vline, /画竖线 自己实现ssd1289_lcd_draw_raw_hline /原始水平线 自己实现; 2.结构体原型struct rt_devicestruct rt_object parent; /* inherit from rt_object */enum rt_device_class_type type; /* device type */rt_uint16_t flag; /* device flag */rt_uint16_t open_flag; /* device open flag */rt_uint8_t device_id; /* 0 - 255 */* device call back */rt_err_t (*rx_indicate)(rt_device_t dev, rt_size_t size);rt_err_t (*tx_complete)(rt_device_t dev, void *buffer);/* common device interface */rt_err_t (*init) (rt_device_t dev);rt_err_t (*open) (rt_device_t dev, rt_uint16_t oflag);rt_err_t (*close) (rt_device_t dev);rt_size_t (*read) (rt_device_t dev, rt_off_t pos, void *buffer, rt_size_t size);rt_size_t (*write) (rt_device_t dev, rt_off_t pos, const void *buffer, rt_size_t size);rt_err_t (*control)(rt_device_t dev, rt_uint8_t cmd, void *args);#ifdef RT_USING_DEVICE_SUSPENDrt_err_t (*suspend) (rt_device_t dev);rt_err_t (*resumed) (rt_device_t dev);#endifvoid *user_data; /* device private data */;使用例子void rt_hw_lcd_init(void) _lcd_device.type = RT_Device_Class_Graphic; /Graphic类 设备驱动_lcd_device.init = lcd_init; /设备初始化自己实现_lcd_device.open = lcd_open; /设备打开约菏迪? _lcd_device.close = lcd_close; /设备关闭自己实现_lcd_device.control = lcd_control; /设备控制自己实现_lcd_device.read = RT_NULL; /设备读_lcd_device.write = RT_NULL; /设备写_lcd_device.user_data = &lcd_ili_ops; /lcd设备私有特性ili9320_Initializtion(); /初始化液晶ili9320_Clear(500);/清屏rt_device_register(&_lcd_device, lcd, RT_DEVICE_FLAG_RDWR | RT_DEVICE_FLAG_STANDALONE); /注册一个设备名字叫lcd 3.结构体原型struct rt_device_graphic_info rt_uint8_t pixel_format; /* graphic format */ rt_uint8_t bits_per_pixel; /* bits per pixel */ rt_uint16_t reserved; /* reserved field */ rt_uint16_t width; /* width of graphic device */ rt_uint16_t height; /* height of graphic device */ rt_uint8_t *framebuffer; /*bits_per_pixel = 16; info-pixel_format = RTGRAPHIC_PIXEL_FORMAT_RGB565P; info-framebuffer = RT_NULL; info-width = 240; info-height = 320; break; case RTGRAPHIC_CTRL_RECT_UPDATE: /* nothong to be done */ break; default: break; return RT_EOK; 三.在应用层启动lcd设备rt_hw_lcd_init();/* find lcd device */lcd = rt_device_find(lcd);/* set lcd device as rtgui graphic driver */rtgui_graphic_set_device(lcd);/* init rtgui system server */rtgui_system_server_init();神舟开发板stm32f107移植代码struct rt_device_graphic_ops lcd_ili_ops = ssd1289_lcd_set_pixel, ssd1289_lcd_get_pixel, ssd1289_lcd_draw_hline, ssd1289_lcd_draw_vline, ssd1289_lcd_draw_raw_hline ; struct rt_device _lcd_device; static rt_err_t lcd_init(rt_device_t dev) return RT_EOK; static rt_err_t lcd_open(rt_device_t dev, rt_uint16_t oflag) return RT_EOK; static rt_err_t lcd_close(rt_device_t dev) return RT_EOK; static rt_err_t lcd_control(rt_device_t dev, rt_uint8_t cmd, void *args) switch (cmd) case RTGRAPHIC_CTRL_GET_INFO: struct rt_device_graphic_info *info; info = (struct rt_device_graphic_info*) args; RT_ASSERT(info != RT_NULL); info-bits_per_pixel = 16; info-pixel_format = RTGRAPHIC_PIXEL_FORMAT_RGB565P; info-framebuffer = RT_NULL; info-width = 240; info-height = 320; break; case RTGRAPHIC_CTRL_RECT_UPDATE: /* nothong to be done */ break; default: break; return RT_EOK; void rt_hw_lcd_init(void) _lcd_device.type = RT_Device_Class_Graphic; _lcd_device.init = lcd_init; _lcd_device.open = lcd_open; _lcd_device.close = lcd_close; _lcd_device.control = lcd_control; _lcd_device.read = RT_NULL; _lcd_device.write = RT_NULL; _lcd_device.user_data = &lcd_ili_ops; ili9320_Initializtion();ili9320_Clear(500);rt_device_register(&_lcd_device, lcd, RT_DEVICE_FLAG_RDWR | RT_DEVICE_FLAG_STANDALONE); 以上代码都要自己编写总体步骤如下配置struct rtgui_graphic_driver_ops；struct rt_device _lcd_device;struct rt_
