THE 8051 MICROCONTROLLER A Systems Approach Muhammad Ali Mazidi Janice Gillispie

Chapter starts from introduction to computing introduces to you a brief introduction of micro computing and Fundamentals and principals of 8051 microcontrollers AT89C51 and its family. The beauty of this book that it teaches you right from Assembly language and C language so that student can easily build applications with the help of its choice language. Microcontrollers understand the instruction given by the program so you will grasp basic instructions like jump, call, loop and variables which is easy to understand and implement. How you interface external devices with 8051 microcontroller and its input output ports, next chapters teaches you about all I/O hardware ports of chip. Authors give you extensive details about 8051 address modes, logic instructions and arithmetic instructions and loops with example programs. Download Pdf eBook THE 8051 MICROCONTROLLER A Systems Approach Muhammad Ali Mazidi Janice Gillispie

In the middle of the book you will start learning how to program 8051 or AT89C52 microcontroller using C language from beginners level to advanced level. How to connect hardware devices with the external pins of 8051 and extensive tutorial on intel hex file. Timers which are the important and widely used component of chip, you will learn and see what are the timers and how they are used in embedded systems. Live practicals are given to handle timers with Assembly language and C language. Connecting and using serial port RS232 is the complex part of any embedded application, but through the example given here in this book you will learn how to communicate with with serial port of AT89S5 microcontroller with external world. Another important hardware routines are interrupts, in the given chapter you will hold the information’s about the what interrupts are and how they work. Practicals also given in Assembly and C language to program interrupts.

When it comes to connect sensors then we think about analog to digital convertor, without which we can not connect any sensor with any microcontrollers, here in AT89S52 we use external Analog to Digital convertor to connect sensor, Digital to analog conversion also defined here in details. LCD and keyboard are basic components of any embedded systems, here in the given examples you will learn how to connect LCD and a keyboard to enter values to systems. Along with this book highlights how to connect and deal with external memories with 8051, Relay, Stepper Motor, opt isolator, DS128887 a time keeping chip for timing operation and display time. DC and AC motors with PWM and I2C and SPI controls are clearly defined for your ease. You can also program NXP p89v51rd2  with the help of this book.
