Microcontrollers and Embedded Systems
FEKT-MPC-MKSAcad. year: 2021/2022
Students learn the advanced features of the C language, its use in microcontrollers programming, and the details of ARM Cortex-M architecture and peripherals of STMicroelectronics STM32 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 STM32 microcontrollers, including the topics of source code management and documentation.
Learning outcomes of the course unit
The graduate is able: (a) describe the structure of ARM Cortex-M core; (b) describe basic blocks of STMicroelectronics STM32; (c) create firmware in C language including GCC specialties; (d) design and use connection of selected microcontroller peripherals; (e) 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.
