As I upload the "Calibration" example onto the board, the LCD begins to display a number of fixed colored dots (like the image attached). It also flashes once a few seconds.

What I want to do is make a menu using graphics loaded from the SD card on the back of the touchscreen. I got the touch working but I seem to be having trouble getting an image to load. I have tried the sd, the sdfat, the sdtinyfat and so on. I am finding very little when I google this stuff because all my results are just people who want to sell me arduino stuff.

Does anyone have a project already written that would save me a lot of time in trying to find 3 examples that work and then melding them together? I am sure someone has already built a GUI with this thing, I just cant find it.

Arduino Mega Touch Screen GUI– In this video tutorial, you will learn how to create a simple touch screen GUI using Arduino Mega TFT 5 inch Touch LCD. This tutorial explains everything that will help you create your own GUI for a 5-inch TFT touchscreen. In this tutorial, a variable resistor will be used as the sensor to display its value on the HMI touch screen. In this tutorial you will also learn how to make buttons and how to write a program to control some Relay, that can be used to control ac or dc loads.

The Arduino board has a wide variety of compatible displays that you can use in your electronic projects. In most projects, it’s very useful to give the user some sort of feedback from the Arduino.

With the TFT display you can display colorful images or graphics. This module has a resolution of 480 x 320. This module includes the SD card socket and SPI FLASH circuit.

RTT-GUIis an open source GUI framework for embedded system. The project is forked fromRT-Thread Package -- GUI Engineand has been heavily refactored for Arduino.

RTT-GUI is built on top of the. The later provides low-level device drivers for the former through common and graphic device operations./* common device operations (RT-Thread: "rtdef.h") */struct rt_device_ops {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, int cmd, void *args);};

/* graphic device operations (RTT-GUI: "driver.h") */struct rtgui_graphic_driver_ops {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);void (*draw_raw_hline)(rt_uint8_t *pixels, int x1, int x2, int y);};

RTT-GUI provides a set of basic graphic functions./* graphic functions (RTT-GUI: "dc.h") */void rtgui_dc_draw_point(rtgui_dc_t *dc, int x, int y);void rtgui_dc_draw_vline(rtgui_dc_t *dc, int x, int y1, int y2);void rtgui_dc_draw_hline(rtgui_dc_t *dc, int x1, int x2, int y);void rtgui_dc_draw_line(rtgui_dc_t *dc, int x1, int y1, int x2, int y2);void rtgui_dc_draw_rect(rtgui_dc_t *dc, rtgui_rect_t *rect);void rtgui_dc_fill_rect(rtgui_dc_t *dc, rtgui_rect_t *rect);void rtgui_dc_draw_round_rect(rtgui_dc_t *dc, rtgui_rect_t *rect, int r);void rtgui_dc_fill_round_rect(rtgui_dc_t *dc, rtgui_rect_t *rect, int r);void rtgui_dc_draw_annulus(rtgui_dc_t *dc, rt_int16_t x, rt_int16_t y, rt_int16_t r1, rt_int16_t r2, rt_int16_t start, rt_int16_t end);void rtgui_dc_draw_pie(rtgui_dc_t *dc, rt_int16_t x, rt_int16_t y, rt_int16_t r, rt_int16_t start, rt_int16_t end);void rtgui_dc_fill_pie(rtgui_dc_t *dc, rt_int16_t x, rt_int16_t y, rt_int16_t r, rt_int16_t start, rt_int16_t end);void rtgui_dc_draw_polygon(rtgui_dc_t *dc, const int *vx, const int *vy, int count);void rtgui_dc_fill_polygon(rtgui_dc_t *dc, const int *vx, const int *vy, int count);void rtgui_dc_draw_circle(rtgui_dc_t *dc, int x, int y, int r);void rtgui_dc_fill_circle(rtgui_dc_t *dc, rt_int16_t x, rt_int16_t y, rt_int16_t r);void rtgui_dc_draw_arc(rtgui_dc_t *dc, rt_int16_t x, rt_int16_t y, rt_int16_t r, rt_int16_t start, rt_int16_t end);void rtgui_dc_draw_ellipse(rtgui_dc_t *dc, rt_int16_t x, rt_int16_t y, rt_int16_t rx, rt_int16_t ry);void rtgui_dc_fill_ellipse(rtgui_dc_t *dc, rt_int16_t x, rt_int16_t y, rt_int16_t rx, rt_int16_t ry);

When finished drawing,rtgui_dc_end_drawing()should be involved to releasedevice contextand trigger rendering process./* device context functions (RTT-GUI: "dc.h") */rtgui_dc_t *rtgui_dc_begin_drawing(rtgui_widget_t *owner);void rtgui_dc_end_drawing(rtgui_dc_t *dc, rt_bool_t update);

RTT-GUI currently supports displaying ASCII and simplified Chinese (Unicode) characters. Two size of fonts are available, 12 and 16 pixel points, for each character set (asc12,asc16,hz12andhz16).

If the SD card driver is available, it is recommended to store the font data (here) in SD card to save space (setCONFIG_USING_FONT_FILE == 1). RTT-GUI by default checks/font/directory for fonts./* font config (RTT-GUI: "guiconfig.h") */#define CONFIG_USING_FONT_12 (0)#define CONFIG_USING_FONT_16 (1)#define CONFIG_USING_FONT_HZ (0)#define CONFIG_USING_FONT_FILE (1)

RTT-GUI currently supports decoding images with the following format:BMPPNG(experimental support), based onLode Vandevenne"s LodePNG projectXPM, RTT-GUI internal used format

All the decoder are optional and configurable./* image decoder config (RTT-GUI: "guiconfig.h") */#define CONFIG_USING_IMAGE_XPM (1)#define CONFIG_USING_IMAGE_BMP (1)#define CONFIG_USING_IMAGE_JPEG (1)#define CONFIG_USING_IMAGE_PNG (0)

/* image functions (RTT-GUI: "image.h") */rtgui_image_t *rtgui_image_create_from_file(const char *type, const char *fn, rt_int32_t scale, rt_bool_t load);rtgui_image_t *rtgui_image_create_from_mem(const char *type, const rt_uint8_t *data, rt_size_t size, rt_int32_t scale, rt_bool_t load);void rtgui_image_destroy(rtgui_image_t *image);void rtgui_image_get_rect(rtgui_image_t *image, rtgui_rect_t *rect);void rtgui_image_blit(rtgui_image_t *image, rtgui_dc_t *dc, rtgui_rect_t *rect);

The most interesting functions are here!RTT-GUI is aclient-serverkind of framework. The server thread starts automatically, which dispatches events to clients. The clients are widgets, which handle events.

Very similar to other event propagation mechanism, a RTT-GUI event is propagating from the topmost widget (a mainWindow) to the deepest widget and the propagation will stop once the event been handled.

EveryRTT-GUI application has to attach to a thread and each thread can be attached byonly one RTT-GUI application.Therefore whenCREATE_APP_INSTANCE()been involved, the new application will attach to the thread that created it. If there is another application already attached,CREATE_APP_INSTANCE()will fail (if so,app == RT_NULL).

The next step is to create a mainWindowholding all other widgets.main_win = CREATE_MAIN_WIN(win_event_handler, "Demo Window",RTGUI_WIN_STYLE_DEFAULT);

Inside the event handler function, we could also involve the defaultWindowevent handler (by involvingDEFAULT_HANDLER(obj)()) and only do something special with the interested events (e.g.PAINT).rt_bool_t win_event_handler(void *obj, rtgui_evt_generic_t *evt) {rt_bool_t done = RT_FALSE;if (DEFAULT_HANDLER(obj)) {done = DEFAULT_HANDLER(obj)(obj, evt);}if (IS_EVENT_TYPE(evt, PAINT)) {done = show_demo(TO_WIN(obj));}return done;}

The parameters ofCREATE_LABEL_INSTANCE():Pointer to parent widget.Pointer to event handler function.Pointer to position and size structure (type:rtgui_rect_t).Label text.

CREATE_BUTTON_INSTANCE()does"t provide the parameter to set position and size. However for any widget, those can be changed by involvingrtgui_widget_set_rect().

A good news is we could use sizer (Box) to automate it.sizer = CREATE_BOX_INSTANCE(main_win, RTGUI_HORIZONTAL, 0);WIDGET_ALIGN_SET(label, STRETCH);WIDGET_ALIGN_SET(btn, STRETCH);rtgui_box_layout(sizer);

The parameters ofCREATE_BOX_INSTANCE():Pointer to parent widget. The parent widget must be aContaineror widget "inherited" fromContainer(e.g.Window).Sizer style,RTGUI_HORIZONTALorRTGUI_VERTICAL.Border size.

When creation complete, the sizer is attached to its parent.rtgui_box_layout()triggers the rearrangement of the positions and sizes of the immediate children of the sizer"s parent.

The final step is to show the mainWindowand spin up the RTT-GUI application.rtgui_win_show(main_win, RT_FALSE);rtgui_app_run(app);DELETE_WIN_INSTANCE(main_win);rtgui_app_uninit(app);

rtgui_app_run()involves theapplication event handlerand doesn"t return until the mainWindowclosed.DELETE_WIN_INSTANCE()andrtgui_app_uninit()then destroy the children widgets and release resources.

Beside programmatical design, a JSON like, text based GUI configuration is also available. The same design in last section can be transformed into the following script.APP: {PARAM: {// name, handler"Demo App", NULL,},MWIN: {PARAM: {// title, handler"Demo Window", hdl,},BOX: {PARAM: {// orient, border size// orient: 1, HORIZONTAL; 2, VERTICAL1, 0,},ID: 0,},LABEL: {PARAM: {// size, handler, textNULL, NULL, "Label Demo",},// CENTER_HORIZONTALTEXTALIGN: 0x01,// RTGUI_ALIGN_STRETCHALIGN: 0x20,},BUTTON: {PARAM: {// handler, type, text// type: 0x00, NORMAL; 0x10, PUSHNULL, 0, "Button Demo",},// RTGUI_ALIGN_STRETCHALIGN: 0x20,},},}

MWINrepresents the mainWindow. There is another element --WIN, represents the normalWindow. One RTT-GUI application can have multiple normalWindows but only one mainWindow.

In sketch side, the first step is involvingrtgui_design_init()to setup parser.design_contex_t ctx;const hdl_tbl_entr_t hdl_tbl[] = {{ "hdl", (void *)win_event_handler },{ RT_NULL, RT_NULL },};obj_tbl_entr_t obj_tbl[1];rtgui_design_init(&ctx, design_read, hdl_tbl, obj_tbl, 1));

The parameters ofrtgui_design_init():Pointer to parser context (value assigned by callee).Pointer to design reading function.Pointer to handler function table.Pointer to object table.Object table size.

When script stored as text file, the function may be defined as below.#define DESIGN_FILE "/design/demo.gui"char buf[512];rt_err_t design_read(char **_buf, rt_uint32_t *sz) {*sz = (rt_uint32_t)read(designFile, buf, sizeof(buf));*_buf = buf;return RT_EOK;}

The next step is paring the design by involvingrtgui_design_parse(). The following example assumes the script is stored as text file.int designFile = -1;designFile = open(DESIGN_FILE, O_RDONLY);rtgui_design_parse(&ctx);close(designFile);

When parsing completed, the requested widget pointers can then be accessed from object table.sizer = (rtgui_box_t *)obj_tbl[0];rtgui_box_layout(sizer);

The RTT-GUI application and mainWindowpointers are available inparser context.rtgui_win_show(ctx.win, RT_FALSE);rtgui_app_run(ctx.app);DELETE_WIN_INSTANCE(ctx.win);rtgui_app_uninit(ctx.app);

You may observe a difference on display after run both demos: For the dynamic design demo, there is no title bar on the mainWindow. The reason is when creating mainWindow, the design parser uses the default style,RTGUI_WIN_STYLE_MAINWIN. However in the other demo, we explicitly use the styleRTGUI_WIN_STYLE_DEFAULT(to show the mainWindowas a normalWindow).
