How to add library to BSP driver and install it in STM32CubeIDE - TouchGFX project

[TTú.1]

Hello everyone!

I am a person who is learning about GUI programming, my project requires interface design on touchgfx software and using STM32F429ZI kit.

I am doing reading a signal from a kit's button, the purpose is to use this signal to trigger another action.

I referenced a sample project from the developer following the link below (From GUI Task -> A working example for STM32F429):

https://support.touchgfx.com/docs/development/ui-development/touchgfx-engine-features/backend-communication

Here I see a sample project that uses the STM32F429I-Discovery library (added in the BSP driver) to use a function that reads data from the kit's button.

I have created a new project that also uses the STM32F429I-Discovery library to read data from the kit's button using the STM32CubeIDE software. I followed the instructions in the link below to add the STM32F429I-Discovery library:

But then I got the error "undefined reference to `BSP_PB_GetState'" in the model.cpp file (the BSP_PB_GetState function is the function that reads the signal from the button, placed in the Model::tick() function of the model.cpp file).

As far as I think the error could be because the file.h and file.c of the library were not linked together when I installed. Or I installed it wrong.

Can someone show me how to correctly add the library to the BSP driver?

Software I am using:

TouchGFX 4.16.1

STM32CubeMX 6.2.0

STM32CubeIDE 1.6.1

This is my project:

Thank you so much everyone!

Hello @Trần Tú​ and welcome to the Community :)

Go to Tool Settings tab and C Compiler->Directories section, then add the new folders containing include files:

../Drivers/BSP/Components/Common

../Drivers/BSP/Components/<library>

../Drivers/BSP/STM32F429I-Discovery

To figure out what is missed in your configuration, please have a look at this ST video, and this article that can help you to add the library to the BSP driver in STM32CubeIDE.
