Hi

I'm using STemWin with STM32F429I Discovery board. I need show a variable on the Dialog. But I Don't know how to text a variable. Is there any example in this regard?

Best Regards

Thank you

Thank you for the reply. I Solved the problem. In the main program, it is necessary to call GUI_Exec () function continuously. If this function is not called, changes can not be displayed on the screen.

this is full code

I Don't know how to text a variable

I don't know what you mean by, 'text a variable' 

But perhaps the standard 'C' library function  sprintf() could help ... ?

Sorry. I mean, How to I write a text on the screen? I can not write anything on the screen. I use STemWin functions but I can not write anything.

void MainTask(void);

void MainTask(void)

{

WM_SetCreateFlags(WM_CF_MEMDEV | WM_CF_CONST_OUTLINE);

GUI_Init();

GUI_CURSOR_Show();

GUI_SetFont(&GUI_Font24B_ASCII);

GUI_DispStringHCenterAt('GUI_Test', 120, 160); //Don't working!!

while(1)

{

STM_EVAL_LEDToggle(LED3);

GUI_Delay(100);

}

}

Can you get the examples working?

What does the documentation say?
