Summary of Content

This course aims to develop the student's hardware, software and interface knowledge and skills to perform the necessary analysis, design and implementation activities to build a microcontroller based embedded system capable of performing its intended task within known cost and performance constraints. On completion, the student will have an expanded grasp of microcontroller architecture and peripheral interfaces in the context of program development and system performance for the embedded environment. The student will also gain additional skills and knowledge to design, implement and debug system solutions using a high-level language and an appropriate integrated development environment. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.

Teaching / Learning Strategy

The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on emerging technologies. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
