STemWin_HelloWorld Example Debugging and GUI_Delay Not Working
Hello Everyone
I am trying to use STemWin with STM32CubeIDE, but facing a lot of problems.
I have STM32F769I Discovery Board with me, and I have downloaded the CubeF7 package which already has few examples related to STemWin, I took the simple example of HelloWorld available as "STemWin_HelloWorld" in the CubeF7 Package.
It works fine, but I am facing two issues.
- First When I am debugging using single stepping, I don't see anything on display.
- Second, I modified the software little bit to display another string on display with some delay and the string after delay which I wanted to display is not displaying on the screen.
The following is the program without delay i.e. GUI_Delay and it works if I program and don't do single step debugging.
void MainTask(void) {
GUI_Clear();
GUI_SetFont(&GUI_Font32_1);
GUI_DispString("Hello World from STM32F7\r\n");
GUI_DispStringAt("Hello world!", (LCD_GetXSize()-100)/2, (LCD_GetYSize()-20)/2);
while(1);
}But when I updated the above program by adding a simple delay of 1 second, it stops displaying the second Hello World message after GUI_Delay.
void MainTask(void) {
GUI_Clear();
GUI_SetFont(&GUI_Font32_1);
GUI_DispString("Hello World from STM32F7\r\n");
GUI_Delay(1000);
GUI_DispStringAt("Hello world!", (LCD_GetXSize()-100)/2, (LCD_GetYSize()-20)/2);
while(1);
}
Also GUI_Delay is not blocking I can see my control reaching while(1) as shown in the below image.
Since this is an example project and I am using demo board from ST, my expectation would be that this should work out of the box.
Can someone please support me with this?
