Microcontrollers, 5 cr

Core content

• Internal structure of micro-controllers: The core of the micro-controller and execution of instructions in the micro-controller. The most common blocks of microcontrollers and their function and control of the blocks. IO interfaces of microcontrollers, their structure and connection to them with peripherals. Devices/components operating at different voltage levels connected to the same system.
• Microcontroller peripherals: AD/DA converters, related basic concepts (LSB, reference voltage, resolution, SAH) and non-idealities (quantization error, offset error, non-linearity) and operating principles of the most common converters. Connecting user interfaces to the microcontroller, simple push buttons and indicators.
• Measurement and control: The general structure of the measurement system and the modification of the analog measurement signal into digital form and the errors that occur in it. The most common sensors, two-mode sensors, temperature sensors, position sensors. Properties of sensors such as resolution, measurement range, accuracy and repeatability, and measurement errors. Actuators. Implementation of different control algorithms with a microcontroller (P, PI and PID).
• Embedded system software: Microcontroller programming in C language. Close programming of the hardware, i.e. setting and examining the status of individual bits. An understanding of what kind of calculations it makes sense to implement with a microcontroller. Memory usage of the C compiler, i.e. variable visibility areas and where the variables are located in the microcontroller's memory. Microcontroller operating systems and their operation. Interruptions and power saving modes.
