Characteristics of This Book
(1) General knowledge and relevant knowledge are well-balanced. From the standpoint of application, this book explains the general principles of the embedded system’s “general knowledge” in a concise but logically lucid way; at the same time, it also pays attention to the coherence between the general knowledge and relevant knowledge about chips. So with the understanding of general principles, the reader can better understand chip application design, which in turn contributes to the understanding of the former.
(2) Both hardware and software design are a concern. An embedded system is the efficient integration of hardware and software. So its design should be a design with coordinated, rather than completely separated, hardware and software, like that of a general computer. It is especially true for intellectual embedded application in electronic systems that embedded software cannot be developed well without considering the hardware, and vice versa.
(3) Component-based packages of low level drivers are provided. Every module in the book has been furnished with a driver program (in line with the basic principles of the embedded software project and the requirement of a component-based package), detailed, with standard notes and an interface. The supply of low-level driver components for practical application facilitates transplantation and reusability, which saves the reader time for developing his project.
(4) Advisable test examples are supplied. Every source program listed in the book has been tested. All test cases are reserved in this book’s CD to free the reader from the trouble caused by design fault or the innate mistake of these example routines, and to facilitate the reader’s confirmation and comprehension.
(5) The CD provides all low-level drivers’ component package procedure, texts and test cases. When used, it also contains a chip reference manual, installation and usage about the writing device, tool software (for example, development environment, program writing and reading software, serial ports adjusting tools, USB device, as well as Ethernet tools), related hardware schematic, other technical information, etc.
(6) Hardware evaluation, writing adjusting device, and software tools that can solely conduct program writing and reading are supplied to facilitate the reader to practice and apply.
There are altogether 16 chapters in this book. The first chapter is an introduction to knowledge system, learning mistakes and learning suggestions on embedded systems. The second and the third chapter describes the characteristics of the ColdFire MCU family, gives the pin function of MCF52233 and the minimum system circuit as well as the first sample program and ColdFire project system to complete the introduction to the first ColdFire project. Chapters 4-10 deal separately with UART, Keyboard，LED and LCD, A/D, Timer，QSPI, I2C and online programming of Flash Memory. And from the eleventh chapter to the fifteenth chapter, information concerning CAN Bus of MCF52235, Ethernet modeling on MCF52233, other modules of MCF52233, USB 2.0 programming of MCF52233, the transplantation and application of μC/OS-Ⅱin ColdFire are provided. The last chapter gives an account of developing methods of embedded systems based on hardware component. Appendix A lists the chip packaging of the ColdFire MCU family used in this book.
