Subject specific learning outcomes and competences
- Students are familiar with general structure of microcontrollers and with the techniques of embedded systems design.
- Students are capable to design and debug the routines and initialization routine for each peripheral device. They are skilled in utilizing of basic debugging techniques for the application programs written in C language.
Generic learning outcomes and competences
Understanding of design specificity of embedded systems using microcontrollers and techniques of application debugging.
To give the students the knowledge of architecture of different microcontrollers. To acquaint with performance of individual subsystems namely CPU- programming model, flash memory, timer, interrupt subsystem, communication interface, AD converter. Make students familiar with basic rules and programming techniques in a high-level language C as well as with embedded system design.
Why is the course taught
Embedded computer systems make up a large and vividly growing market, which is supposed to be expanding even further with the progressive deployment of the Internet of Things (IoT) concept. One aspect is comprising application of computers and their programming, just as those are generally known. But in the same time, it is also possible to distinguish certain specifics and particularities related to the application and programming of embedded computer systems which, from the perspective of traditional computers, are deemed to hold just some marginal importance or do not need to be addressed at all. Such an interpretation is essentially given by the strong binding of an embedded computer to the underlying hardware and surrounding processes in its vicinity. A typical embodiment of a computer for embedded applications is so called microcontroller, which is a device conceived as an entire computer available on a single chip where it's coupled with various interfaces and range of supporting hardware modules useful for simplification, speed-up or mitigation of the burdens otherwise connected with applications programming.
The overall volume of microcontrollers fabricated annually on a global scale falls into the range of tens of billions. It is important to highlight the fact that thanks to the flexibility of software solution the microcontrollers not only open a way how to carry out various innovations and achieve price reduction of wide range of existing systems and applications (from toys to home appliances, vehicles, manufacturing processes and industrial machines), but their utilization constantly unlock also new possibilities, products and entirely new market segments (e.g. previously mentioned IoT concept), which would be otherwise even hard to imagine without the existence of this type of computers. Within the framework of the IMP course students have the chance to make themselves acquainted with various principles behind the programming and deployment of contemporary microcontrollers. They will also become familiar with the typical modules available in those chips, their usage under various application scenarios. Finally, students should get an understanding of fundamental problems connected with embedded systems based on microcontrollers and learn about the approach to their solution.
