Dear, I have the demo board STM32F4-discovery MB1075C

Use new STM32CubeIDE 1.3.0

Now I start a new project with this board, i need to add the emWin libray.

I have configurated the link to library and copy the file from STM32Cube_FW_F4_V1.25.0

When add the call GUI_Init(); i have this error at linking time:

GUI_Core.c:(.text.GUI__Config+0x62): undefined reference to `GUI_X_Config'

GUI_Core.c:(.text.GUI__Config+0x66): undefined reference to `LCD_X_Config'

Add the project file

Is the first time that i use the emwin

Thanks for help

Read the emwin documentation.

You have to provide these functions yourself, because stemwin has no idea what kind of display do you have and how it is connected.

You might be able to use the ones in the STM32Cube_FW_F4_V1.25.0/Projects/STM32F429I-Discovery/Demonstrations/STemWin/Gui/Target directory as a starting point.

You should implement both functions. Not just read the example, but write your own functions based on it.
