The 8051/8052 Microcontroller
This book was written with the novice or intermediate 8052 developer in mind. Assuming no prior knowledge of the 8052, it takes the reader step-by-step through the architecture including discussions and explanations of concepts such as internal RAM, external RAM, Special Function Registers (SFRs), addressing modes, timers, serial I/O, and interrupts. This is followed by an in-depth section on assembly language which explains each instruction in the 8052 instruction set as well as related concepts such as assembly language syntax, expressions, assembly language directives, and how to implement 16-bit mathematical functions. The book continues with a thorough explanation of the 8052 hardware itself, reviewing the function of each pin on the microcontroller and follows this with the design and explanation of a fully functional single board computer-every section of the schematic design is explained in detail to provide the reader with a full understanding of how everything is connected, and why. The book closes with a section on hardware interfacing and software examples in which the reader will learn about the SBCMON monitor program for use on the single board computer, interfacing with a 4x4 keypad, communicating with a 16x2 LCD in direct-connect as well as memory-mapped fashion, utilizing an external serial EEPROM via the SPI protocol, and using the I2C communication standard to access an external real time clock. The book takes the reader with absolutely no knowledge of the 8052 and provides him with the information necessary to understand the architecture, design and build a functioning circuit based on the 8052, and write software to operate the 8052 in assembly language.

Since its debut by Intel in the 1980s, the 8051 microcontrollers have been widely used in embedded systems. It is considered to be a pioneering microcontroller. It is widely acknowledged that the 8051 architectures, which is renowned for its ease of use and durability, served as the basis for several succeeding microcontroller designs. An 8-bit Central Processing Unit (CPU), 128 bytes of Random Access Memory (RAM), 4 KB of Read-Only Memory (ROM), and a collection of adaptable peripherals, including as timers, serial ports, and input/output (I/O) pins, are all included in this device. Because of these characteristics, the 8051 is a very dependable and effective technology that can be used in a broad variety of applications, ranging from simple consumer electronics to intricate industrial control systems. One of the most important advantages of the 8051 microcontroller is its adaptability, which is a direct result of its capacity to readily connect with components that are external to the electronic device. The microcontroller is capable of simultaneously supporting parallel and serial communication, which enables it to integrate without any problems with other digital devices and sensors. In addition, despite the fact that its instruction set is very limited, it is powerful enough to perform a variety of activities, including arithmetic operations, data transmission, and logic control. As a result of this mix of features, the 8051 has become a common tool in both education and industry. It is often used as the starting point for students studying embedded systems and for professionals designing real-time applications. It is also possible to credit the durability and lasting popularity of the 8051 to the fact that it is widely available and that there is a massive ecosystem of development tools and materials available. An extensive number of versions and clones of the original 8051 microcontroller have been manufactured. Each of these variants and clones offers improvements such as greater memory, better processing speeds, and extra peripherals respectively. Despite the development of more sophisticated microcontrollers, the 8051 continues to be useful because of its ease of use, dependability, and the abundance of pre-existing code and applications that continue to rely on its design.
Microcontroller Projects in C for the 8051
This book is a thoroughly practical way to explore the 8051 and discover C programming through project work. Through graded projects, Dogan Ibrahim introduces the reader to the fundamentals of microelectronics, the 8051 family, programming in C, and the use of a C compiler. The specific device used for examples is the AT89C2051 - a small, economical chip with re-writable memory, readily available from the major component suppliers. A working knowledge of microcontrollers, and how to program them, is essential for all students of electronics. In this rapidly expanding field many students and professionals at all levels need to get up to speed with practical microcontroller applications. Their rapid fall in price has made microcontrollers the most exciting and accessible new development in electronics for years - rendering them equally popular with engineers, electronics hobbyists and teachers looking for a fresh range of projects. Microcontroller Projects in C for the 8051 is an ideal resource for self-study as well as providing an interesting, enjoyable and easily mastered alternative to more theoretical textbooks. Practical projects that enable students and practitioners to get up and running straight away with 8051 microcontrollers A hands-on introduction to practical C programming A wealth of project ideas for students and enthusiasts
