Without interfacing, a microprocessor is just a calculator. Hall dedicates nearly 40% of the 3rd Edition to hardware. The crown jewels include:
Chapter 7: Memory Interfacing
Chapter 8: Basic I/O Interfacing
Chapter 9: Parallel Communication – 8255 PPI
Chapter 10: Serial Communication – 8251 USART Microprocessors And Interfacing Douglas V Hall 3rd Edition
Microprocessors and Interfacing: Programming and Hardware (3rd Edition)
by Douglas V. Hall is a foundational textbook widely used in electrical and electronic engineering. The book provides an in-depth exploration of the Intel 8086 family, covering architecture, assembly language programming, and hardware interfacing. Key Concepts and Core Topics Without interfacing, a microprocessor is just a calculator
This is where the book distinguishes itself from general programming texts.
Simply reading Douglas V. Hall will not make you an expert. You must build. Here is a lab sequence derived from the book that you can still do today (using emulators or real hardware). Chapter 8: Basic I/O Interfacing
The book is organized to move from fundamentals to applied interfacing:
