Seminar:

  • Selection of topics,
  • Product design including a micro-controller,
  • Basic software design,
  • Practical micro-controller programming,
  • Software troubleshooting,
  • Presentation for the other participants.

Objectives:

The ability to build a micro-controller, efficient use of its built-in peripherals and writing the corresponding software to solve a practical problem in an apparatus that requires some form of a micro-controller support. Testing the final product, hardware and software error detection and correction.

Competences (occupation specific):

  • Knowledge of different-technology micro-controllers and their capabilities,
  • Knowledge of programming methods and corresponding programming tools for micro-controllers,
  • Problem solving in an apparatus that requires micro-controller support.

Knowledge and understanding:

  • Knowledge of the internal structure of a micro-controller,
  • Knowledge of core and peripheral programming,
  • Knowledge of programming tools,
  • Understanding the capabilities of micro-controllers to solve practical problems,
  • Knowledge of writing efficient micro-controller software.

Learning and teaching methods:

Lectures, laboratory courses, practical construction and programming of prototype devices in the laboratory. Participants can also carry out part of the practical work independently, outside of the laboratory exercises and then bring the final product to the review and assessment on the last laboratory exercise. After the pedagogical work, participants independently design, construct and test their own product.
