This book is a practical guide used for implementing lab experiments and is a part of "Embedded system design and implementation" course. This lab manual is based on the PIC Microcontroller namely PIC18F4550. It is a part of the teaching and training tool for developing Embedded Systems. The book contains 8 experiments that include: Labs for the embedded software development fundamentals; Labs for basic interfaces. This book offers examples for the embedded system learners. The Labs form an embedded system teaching or training tool and are introduced in a very understandable manner. The initial chapters deal with the introduction part that may be used in the implementations. LED blinking and use of push buttons are mentioned later. Chapter 5 introduces 7 segment displays and their operation with the PIC microcontrollers. Chapter 6 shows the interface of PIC with the LCD device. Chapter 7 demonstrates an example of a temperature sensor and its integration with LCD. Chapter 8 showsa keypad and an LCD project. This book can be used by undergraduate students with majors in Electrical Engineering, Computer science and Engineering students etc as well, as self-learners.
