Embedded systems within the context of this text includes computer control systems. In order to implement control software programming is required for a dedicated micro-controller. It is also necessary to interface the sensors and actuators to the micro-controller so that the required control action can be implemented. This text provides an overview of embedded systems from this perspective. The details are excluded in favour of a more general understanding of the approach. There are examples of C and assembly programming and also aspects of the computer architecture of the 80x51 family of micro-controllers. Some very basic aspects of discrete modelling and control in discrete time domain are presented. Also included are course notes for Embedded Systems programming for the Intel 8051 family of processors. The course is intended to use the Keil software development suite.
