EEE3261 Microcontroller and Embedded Systems
Semester II
EEE3261 Microcontroller and Embedded Systems

The primary objective of this module is for the students to develop the ability to design microcomputer-based embedded systems.

This class allows students to learn microcomputer interfacing from both a hardware and software perspective.

This course provides a basic understanding of embedded computer systems:

Hardware/software systems and co design, peripheral devices, Principles and practice of using Embedded RTOS (Real Time Operating System) and peripheral devices such as sensors and actuators to build a small embedded system, Peripheral interfacing methods and standards, Analog digital conversion methods and interfacing, Low power design, Design methodologies and tools. 

Students will gain design experience with project/case studies using contemporary high-level methods and tools.

Below is the course delivery schedule.
