Currently recommended development tools and components

We have prepared a summary table in which you can find which STM32 development card (Nucleo / Discovery) and which additional elements you can use to try out what is described in the course material.
The example codes must be rewritten (ported) according to the given card, but you will find help for this in the first chapters of the course material.
For example, when creating a project in STM32CubeIDE, you select the available board, then in the hardware configurator you set the device according to the example code.
The project can then be compiled by copying the appropriate files of the example codes.
In the schools that test the curriculum, the students use a unique development card that can be seen in the curriculum, but we have not yet found a suitable opportunity to produce it. The suggestions in the table above offer cheap, full-featured, generally available solutions.
