The 8051 Microcontroller and Embedded Systems: Using Assembly and C

0.0

Microcontrollers are used in video games, automobiles, toys, robotics, and every electronic device imaginable to perform specific functions and enrich our lives. One of the most widely produced microcontrollers in the world is the 8051, which is produced by more than fifty companies and is one of the most popular to study. This textbook covers the hardware and software features of the 8051 in a systematic manner. Using Assembly language programming in the first six chapters, it provides readers with an in-depth understanding of the 8051 architecture. From Chapter 7, this book uses both Assembly and C to show the 8051 interfacing with real-world devices such as LCDs, keyboards, ADCs, sensors, real-time-clocks, and the DC and Stepper motors, The use of a large number of examples helps the reader gain mastery of the topic rapidly and move on to the topic of embedded systems project design.
