AIM
To give sufficient background for undertaking embedded systems design.
OBJECTIVES

• To introduce students to the embedded systems, its hardware and software.
• To introduce devices and buses used for embedded networking.
• To explain programming concepts and embedded programming in C and C++.
• To explain real time operating systems, inter-task communication and an exemplary case of MUCOS – IIRTOS.
