Resolved! Unit test: access code in one project by another project in the same workspace

I want to setup simple unit testing using something like tinytest or minctest running on the target processor. The idea is to have the application project and a test project in the same workspace. The test project will only implement a UART for repor...

Resolved! Hello, i have on my table the STM32L476 Nucleo-64 board and i installed for the first time the STM32CubeIDE. Do i have to install all STM32L4 available MCU package release versions or do i only need the latest version and ignore the older releases?

Resolved! Please help with porting this arduino library. I have to use HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive to write to an i2c and I have no clue how to do.

What does the key symbol mean on top of my source folders?

Thank you

Ceedling test framework fails to compile mock HAL libraries when working with unit tests. I was wondering if there are any additional configurations to the project to make this work. I have attached the test file and the terminal output to this question.

I am trying to set up an embedded test framework in STM32 Cube IDE. Ceedling framework works properly when there is no dependency on external libraries. However, when trying to mock any HAL library the compilation process fails. Thank you
