Microcontrollers for Advanced Applications
FEKT-GMIAAcad. year: 2019/2020
Students learn the advanced features of the C language, its use in microcontrollers programming, and the details of architecture and peripherals of Atmel AVR MCUs. They learn to design and program drivers for the most common peripherals such as button inputs, multiplex displays, graphic displays, shift registers, temperature sensors, etc. The course shows the procedures necessary for the design of complex applications with AVR microcontrollers, including the topics of source code management and documentation.
Learning outcomes of the course unit
The graduate is able: (1) describe different AVR microcontroller blocks including advanced functions, (2) create firmware in C language including AVR-GCC specialties, (3) discuss different types of displays for microcontroller applications, (4) discuss advantages and disadvantages of different busses for microcontrollers, (5) design connection of different microcontroller peripherals, (6) design and assemble own device with microcontroller including firmware.
Attendant should be able to:
- describe main microcontroller blocks and their function
- design simple C program
- design program for setup of basic peripherals, interrupt control and separate functions and function calls
- analyze simple electronics circuits with passive parts and transistors and choose corresponding way of connecting to the microprocessor.
The subject knowledge on the Bachelor's degree level is requested.
