1 - Introduction
Chapter 11: Conclusion.
Chapters 1, 2 and 3 are a refresher on the concept of a microcontroller. Chapter 1 introduces
the concept, Chapter 2 addresses the hardware and Chapter 3 addresses the software as-
pects.
Chapters 4 through 7 describe the ST7 and its programming tools, taking only assembly lan-
guage into account.
Chapter 8 discusses the C language and techniques for using the C Compiler for the ST7 mi-
crocontroller, its strengths and also its limitations.
Chapters 9 and 10 describe application projects using the ST72251 and the ST72311 mem-
bers of the ST7 family. They tell the story of the design of devices that, though they do work,
were not intended to be commercial products.
1.4 WHY A MICROCONTROLLER?
The microcontroller is just another choice when one has to design an application, and it com-
petes with other technologies, like wired logic, a microprocessor system, or a Programmable
Logic Device of which many types are available.
All these solutions tend to reduce the number of components, the area of printed circuit used,
the number of connections, while increasing the computing power and keeping the cost low.
