This sort of "busy" loop for timing is not really a good ideas as it prevents the CPU from doing other work while you delay. svcSleepThread is likely a better solution.
void svcSleepThread(s64 ns);
Where ns is the time to sleep in nanoseconds.

Thanks you but again, still freeze :S

@umbjolt , this should work:

#define TICKS_PER_MSEC (268123.480)

void showRomPathMarquee(const int XposValue,int Ypos, std::string text) {
   std::string path = text;
 
   while(!(hidKeysDown() & KEY_UP)){
       std::string scrolled,temp,temp2;
       hidScanInput();
       sf2d_start_frame(GFX_TOP, GFX_LEFT);
       sf2d_start_frame(GFX_TOP, GFX_LEFT);      
       temp = path.substr(1,(path.length()));
       temp2 = path.substr(0,1);
       path = temp + temp2;
       if(path.length() + 1 == ' '){
           sftd_draw_textf(font, XposValue, Ypos, SET_ALPHA(color_data->color, 255), 12, "%s %s", temp.c_str(), temp2.c_str());
       }else{
           sftd_draw_textf(font, XposValue, Ypos, SET_ALPHA(color_data->color, 255), 12, "%s", path.c_str());
       }
       sf2d_end_frame();
       sf2d_swapbuffers();
       svcSleepThread(500000000 ); // sleep for 0,5 sec
   }
}

There is only the part "if(path.length() + 1 == ' ')" that I don't understand.

Thanks you Later I'll test it
Still no dice and freeze but after pressing UP a lot of times seems to "unfreeze" and let me press HOME but text is impossible to read neither

 

[elhobbs]

Thanks you but again, still freeze :S

Not really familiar with sftd but if it is using hardware rendering than you are using it wrong. Also, as I already indicated, svcSleepThread expects time in nanoseconds - not ticks converted to milliseconds.
Likely your program is running briefly without updating the screen before overflowing the rendering command buffers and crashing.

 

[nop90]

svcSleepThread expects time in nanoseconds - not ticks converted to milliseconds.

Is it changed in the last year? Maybe I remember wrong, but thought it used ticks. (Noe checked the documentantion and it says milliseconds)

@umbjolt the previous example miss some code for sf2d, like :

sf2d_start_frame(GFX_TOP, GFX_LEFT);
 ...
sf2d_end_frame();
sf2d_swapbuffers();

I edited the above code. But don't have time to test it for other missing things.

That is odd. The note in the header file says nanoseconds.

/**
* @brief Puts the current thread to sleep.
* @param ns The minimum number of nanoseconds to sleep for.
*/
void svcSleepThread(s64 ns);

Thanks again but still the fucking while loop freeze the console. I've tested without the while and it doesn't freeze at all. Also, pressing UP key doesn't break the while so maybe it's a limitation with the console?

You're right. I'm too much under pressure at work to be lucid.

I need some rest and more sleeping.

Hi, is there a way to get a sound (recorded from mic but it doesn't matter) frequency?

What do you mean with frequency? A sound sample has a frequency spectrum, not a single frequency value. If you're searching the fundamental frequency, like does a guitar tuner, you have to know a lot of math (there is a not working tuner for the 3ds on my github)

How do I make animated banner?

I'm going to ask the most stupid question on the world.
-1 is true or false? I always get confused
Because some languages 0 is true and others false but dunno what happen with negatives (in this case) ^^u

Don't know if it's standard C or if it is compiler dependant (should be ANSI C) , but usually false is 0, so that a NULL pointer (= 0 address) can be evaluated as false.

Any value !0 is evaluated to true.

To define a bool type with a conventional value for true, it s a good choice to select the value -1 defining the bool type as a signed numeral (usually s32), so it's easy to swap between true and false with the ~ operator (true == ~false only and only if true is a signed value set at -1, i.e. all bit set).

I was trying yo remove the compiler warning (here) so, if I have understood you, I have to change "res == -1" to "res"?

Should work. Try and test it.

I removed sftdlib from TWLoader, and replaced it with citro3D for rendering text in the system font.
With citro, the text shows up just fine, but after a second, the text disappears.
Am I missing something?

The text.
Seriously though - without some code no one will be able to help you. Because clearly you are doing something wrong.

There's this at the beginning of int main, which inits Citro3D.

    C3D_Init(C3D_DEFAULT_CMDBUF_SIZE);
    if (logEnabled)    LogFM("Main.C3D_Init", "Citro3D inited");

    // Initialize the render target
    C3D_RenderTarget* target = C3D_RenderTargetCreate(240, 400, GPU_RB_RGBA8, GPU_RB_DEPTH24_STENCIL8);
    C3D_RenderTargetSetClear(target, C3D_CLEAR_ALL, CLEAR_COLOR, 0);

    printf("System font example\n");
    Result res = fontEnsureMapped();

    if (R_FAILED(res))
        printf("fontEnsureMapped: %08lX\n", res);

    sceneInit();

And I replaced the sftd draw text functions with citro's renderText function, along with setTextColor, which sets the following text's color.
That's all I did.

Which is why it does not work. Take a look at one of the minimal citro3d examples for the pieces you are missing. There are begin and end frame functions you need to be calling. https://github.com/devkitPro/3ds-examples/tree/master/graphics/gpu/simple_tri

Is this right?

                    C3D_FrameBegin(C3D_FRAME_SYNCDRAW);
                    textVtxArrayPos = 0; // Clear the text vertex array
                    // Update the uniforms
                    C3D_FVUnifMtx4x4(GPU_VERTEX_SHADER, uLoc_projection, &projection);
                    sf2d_start_frame(GFX_TOP, (gfx3dSide_t)topfb);
                    // --> Draw textures and (by Citro3D) text <--
                    sf2d_end_frame();
                    C3D_FrameEnd(0);

Text still disappears.
I'm kinda new to using Citro with other graphic libs.
