Objectives and competences:
Objectives:
Ability to independently build a microcontroller, to use the built-in I/O units efficiently and to write software in order to solve a specific task in a device that needs the support of a microcontroller. Testing of the final product, detecting and correcting hardware and software faults.
Competences (vocationally specific):
- Knowledge of microcontrollers of different technologies and capabilities,
- Knowledge of the programming method and associated software tools for microcontrollers,
- Solving a task in a device that requires microcontroller support.
Methods:
Lectures, tutorials and practical building and programming of a prototype device in the laboratory. Participants may also carry out part of the practical work independently outside the laboratory tutorials, and bring the final product to the final tutorial for review and assessment. After the tutorial, the participants will independently design, build and test the device according to their own ideas.
