A microcontroller is a microcomputer on a silicon chip. When a microcontroller is in a device that is not a computer, it is called an embedded controller. Examples of typical devices would be telephones, televisions, copy machines, microwave ovens and in automobiles. Automobiles incorporate more than ten microcontrollers used for such applications as controlling air/fuel mixtures in the engine to antilock brakes at the wheels. This course focuses on the fundamentals of both the hardware and software aspects of the microcontroller. Typical devices that are connected to the microcontroller are; switches, light emitting diodes, seven segment displays, pneumatic solenoids and a matrix keypad. An engineering evaluation board is used as the development system for the embedded controller. Structured programming, using flow charts, is emphasized. Code is written in assembly language, assembled and then downloaded to the Engineering Evaluation Board.
