    is there any options to remove the 3D efforts of the widgets? for example the button looks like it has some shadow effects, in order to remove this i try to remove some codes like below

        void gwinButtonDraw_Normal(GWidgetObject *gw, void *param) {
            const GColorSet *    pcol;
            fixed                alpha;
            fixed                dalpha;
            coord_t                i;
            color_t                tcol, bcol;

            (void)                param;

            if (gw->g.vmt != (gwinVMT *)&buttonVMT)    return;
            pcol = getButtonColors(gw);
        
            /* Fill the box blended from variants of the fill color */
            //tcol = gdispBlendColor(GFX_WHITE, pcol->fill, BTN_TOP_FADE);
            //bcol = gdispBlendColor(GFX_BLACK, pcol->fill, BTN_BOTTOM_FADE);
            //dalpha = FIXED(255)/gw->g.height;

            //for(alpha = 0, i = 0; i < gw->g.height; i++, alpha += dalpha)
            //    gdispGDrawLine(gw->g.display, gw->g.x, gw->g.y+i, gw->g.x+gw->g.width-2, gw->g.y+i, gdispBlendColor(bcol, tcol, NONFIXED(alpha)));

            gdispGDrawStringBox(gw->g.display, gw->g.x, gw->g.y, gw->g.width-1, gw->g.height-1, gw->text, gw->g.font, pcol->text, justifyCenter);
            //gdispGDrawLine(gw->g.display, gw->g.x+gw->g.width-1, gw->g.y, gw->g.x+gw->g.width-1, gw->g.y+gw->g.height-1, pcol->edge);
            //gdispGDrawLine(gw->g.display, gw->g.x, gw->g.y+gw->g.height-1, gw->g.x+gw->g.width-2, gw->g.y+gw->g.height-1, pcol->edge);

            // Render highlighted border if focused
            _gwidgetDrawFocusRect(gw, 0, 0, gw->g.width-1, gw->g.height-1);
        }

    it did work for me , the button just show texts right and can be toggled.

    i wonder is there any better ways to do this? 

  7. the gwin/button demo doesn't work

    thanks a lot for reply,  i tried to set GFX_COMPILER to GFX_COMPILER_KEIL  but it didn't work for me. 

    and then i turned off stack checking it did work well but i think it's not a good way to turn it off, other threads still need this to ensure safety running.

    you mentioned i should see rawrtos or freertos or cmsisv2 for examples then i followed the wiki about using uGFX on freertos,  wrote my program like below

      

    static void taskInit(void* pvParameters)
{
    (void)pvParameters;
 
    gfxInit();
}
 
void main(void) {
    // Create the initialization task
    xTaskCreate(taskInit, "Initialization", stackSize, 0, priority, 0);
 
    // Initialize FreeRTOS. This will start the scheduler.
    vTaskStartScheduler();
}

    but... still stack overflow with my stack checking on.

    what should i do now? i don't know much about mcu arch or Makefile. could you give me a simple to do this?

    i try to debug this and i found the program runs into this function

    bool_t gfxSemWait(gfxSem *psem, delaytime_t ms) ;

    i put a log function at the entry of this function

    rt_kprintf("gfxSemWait ok!\n");

    and i found the the log showed 4 times

    gfxSemWait ok!
    gfxSemWait ok!
    gfxSemWait ok!
    gfxSemWait ok!

    and then "stack overflow" again

    i specified the CPU type to be m7 and i modified the gos_x_threads_cortexm347.h file because arm9 is an arm920T V4T cpu , it dosen't support the "blx" instruction so i change that line to be  

    mov          lr, pc
    bx              r1

    and then i builded and run ,  at last , i could see the button show on the screen, but another problem shows, the RTOS(a chinese rtos named rtthread) which uGFX ran on has a "stack overflow" issue immediately,  i set the uGFX thread stack to be 200K Bytes , i think it is big enough for it,  but stiil "stack overflow".  then i comment the whie() part code


        while(1) {
            // Get an Event
    //         pe = geventEventWait(&gl, TIME_INFINITE);
    // 
    //        switch(pe->type) {
    //            case GEVENT_GWIN_BUTTON:
    //                if (((GEventGWinButton*)pe)->gwin == ghButton1) {
    //                    // Our button has been pressed
    //                    if (++which >= sizeof(orients)/sizeof(orients[0]))
    //                        which = 0;
    //
    //                    // Setting the orientation during run-time is a bit naughty particularly with
    //                    // GWIN windows. In this case however we know that the button is in the top-left
    //                    // corner which should translate safely into any orientation.
    //                    gdispSetOrientation(orients[which]);
    //                    gdispClear(White);
    //                    gwinRedrawDisplay(GDISP, FALSE);
    //                }
    //                break;
    //
    //            default:
    //                break;
    //        }
        }

    nothing wrong with the RTOS now but i could't see the button too, what happened?

    the RTOS's website is https://github.com/RT-Thread/rt-thread it's widely used in china

     

  10. ILI9341+MAPS-KS22+BareMetal doesn't work

    i configurer my project following the bare metal guide, i filled these two functions 

    systemticks_t gfxSystemTicks(void)
{
	return HAL_GetTick();
}
 
systemticks_t gfxMillisecondsToTicks(delaytime_t ms)
{
	return ms;
}

    and i also filled the driver functions in "drivers\gdisp\ILI9341\board_ILI9341.h", and i copied demo/disp/basic code to my main.c the prroject can be builded and run but i just can't see any thing. the only one can work is gfxinit() function, it did init my scrreen

    what should i do to specified the CPU to uGFX？i have checked the gfxconf.h and i found  3 options below

      #define GFX_CPU                                  GFX_CPU_UNKNOWN

       #define GFX_CPU_NO_ALIGNMENT_FAULTS              FALSE
       #define GFX_CPU_ENDIAN                           GFX_CPU_ENDIAN_UNKNOWN
