FAQ

  • The demo project doesn't compile successfully. Help!
  • The project was made with older version of STM32CubeIDE, and version 1.11.0 introduced some major changes to  the compiler. In order to compile the project successfully (to force the environment behave like it used to), please do the following:

    - In the Project Explorer right-click over the name of the project and go to "Properties" at the bottom;
    - New window will pop up and under "C/C++ Build select Settings";
    - Go under "MCU GCC Compiler" and select "Miscellaneous";
    - Add new flag from the small green plus sign named "Add..";
    - add "-fcommon" and save and "Apply and Close".

    Refer to the picture on how it looks here: picture of software workaroud.

    Then clean the project and then build it. There should be a few warnings that can be ignored but now the project will compile and work fine.

    Alternatively, you can just use older version of STM32CubeIDE. We previously used STM32CubeIDE 1.10.0 without issues.
  • What battery can I use with the battery holder?
  • The battery holder requires very special battery that provide 3V and comes in AA size. Alternatively you can use 2x1.5V batteries that are much easier and cheaper to find. Even you can use rechargeable 1.5V AA batteries. Yes, they won't fit the original connector but you can use ready product - search online for BAT-HOLDER-2xAA and connect the free leads to the on-board battery holder.
