Simplifying the Development of Programs for Digital Engine Controllers

The paper describes a method of simplifying the preparation and development of control programs for microprocessor-based engine control systems. The system described employs a video display unit, VDU, connected to the digital controller. Programs are prepared in a simple high level language tailored to the requirements of engine control schemes. The paper also describes the internal software structure and features that are provided. An example of the procedures used to develop a simple control program illustrates how a user can concentrate on the control scheme rather than on software problems.
