Touchgfx and HAL_GPIO_WritePin in simulator

[amigafan]

This piece of code works if I transfer it to my board, but if I use the simulator in TouchGFX, I get an error: gui/src/model/Model.cpp:7:10: fatal error: main.h: No such file or directory #include "main.h".

 

Screen1View.cpp

#include "stm32f7xx_hal.h"

 

// LED Toggle function

void Screen1View::ToggleLED()

{

 if (toggleButton1.getState()) HAL_GPIO_WritePin(GPIOA, GPIO_PIN_0, GPIO_PIN_SET);

 else HAL_GPIO_WritePin(GPIOA, GPIO_PIN_0, GPIO_PIN_RESET);

}

 

I am using TouchGFX 4.24

Ups, the error is:gui/src/model/Model.cpp:7:10: fatal error: stm32f7xx_hal.h: No such file or directory #include "stm32f7xx_hal.h". Sorry

Hello @amigafan ,

How did you include the file in your project ? The board and the simulator are built differently.

 

Best regards,

?? I wrote #include "stm32f7xx_hal.h" in Screen1View.cpp.

I meant in which folder did you put the file ?

[amigafan]

It is in STM32CubeIDE, I dit no add a file to any folder.

Hello @amigafan,

The issue is the file itself, it's an hardware specific file that will only work on target.

 

#ifdef SIMULATOR

 // Your simulator specific user code here

 #include "gui/common/myInclude.hpp"

#else
 // Your hardware specific user code here

 extern "C"

 {

 #include "stm32f7xx_hal.h"

 }

#endif
 

 

I hope it helps,
Best regards

extern C is not needed as stm32f7xx_hal.h already has this inside the header file. As far as I know all ST header files are like this.

 

This would work:

 

#ifndef SIMULATOR
#include "stm32f7xx_hal.h"
#endif

// LED Toggle function
void Screen1View::ToggleLED()
{
	if (toggleButton1.getState())
	{ 
		#ifndef SIMULATOR
		HAL_GPIO_WritePin(GPIOA, GPIO_PIN_0, GPIO_PIN_SET);
		#else
		//simulate an LED on the screen, for example
		#endif
	}
	else
	{
		#ifndef SIMULATOR
		HAL_GPIO_WritePin(GPIOA, GPIO_PIN_0, GPIO_PIN_RESET);
		#else
		//simulate an LED on the screen, for example
		#endif
	}
}
