Question

Linker errors for sensor data processing functions in STM32CubeIDE + TouchGFX

Hello everyone,

I’m developing an STM32H750 application using STM32CubeIDE and TouchGFX, and I’m trying to integrate a sensor using I2C.

I implemented a sensor driver and added the corresponding source files, but I’m running into linker errors like:

undefined reference to `Sensor_Calc()'

I made sure the source files are included in the build and headers properly referenced, but the errors persist.

If anyone has working examples, suggestions, I’d be grateful.

Thanks for your help!

Hello @Rafla

Maybe you can present more details.

It's hard to identify your bug with the information given.

Thanks.

The code compiles fine on the real target, but when I try to build the TouchGFX Simulator, I get the following error repeatedly:

fatal error: i2c_data.h: No such file or directory

The i2c_data.h file is present in my project under Core/Inc.

It seems the simulator build does not include the folder containing i2c_data.h in its include paths.

You dont show code , but for C++ you maybe skip use right C headers...

Learn how use

#ifdef __cplusplus
 extern "C" {
#endif
