How to integrate and build the Adafruit Gamepad QT seesaw C++ library for the Nucleo-G071RB

[Kmax18]

The goal is to test the Adafruit Gamepad QT with the Nucleo-G071RB board. This requires using the Adafruit seesaw C++ library of source files, which transmits analog joystick signals using the I2C protocol.

I used the code example I2C_TwoBoards_ComPolling (C-code) as a starting point an...

• Added both the Adafruit seesaw and BusIO libraries (C++ code) to the project,
• Updated the Project Include paths,
• Added the library paths to the Project Source Locations (Figure 1), and
• Renamed the main.c file to main.cpp.

Problem: the project does not built the Adafruit libraries, the compiler just ignores them.

What is the solution for this? How do I build the entire project, including the Adafruit libraries? Thank you!!!

The solution is to convert the STM32CubeIDE project from a C to a C++ project. In the Solution Explorer right-click the project and select "Convert to C++".  I wrongly assumed that renaming the main.c to main.cpp is sufficient, but it is not.
