Prolific author Fred Eady has done it again. Microchip's PIC18 is a low-cost microcontroller (MCU) with an on-chip ethernet interface. With step-by-step instruction Eady shows the reader how to build hardware nodes from these MCUs for use in sensor devices, internet, and security systems. This book will cover the PIC18F97J60 family of devices. It will detail all the differences of the family members and then explain the building of a hardware node on the PIC18F67J60, PIC18F87J60, and PIC18F97J60. TCP/IP will be covered introductorily and how it specifically pertains to these MCUs. When the reader finishes this book, he/she will have the knowledge necessary to build an ethernet node from scratch! Filled with examples for a truly hands-on approach, it discusses the TCP/IP stack as it pertains to PICs, a subject foreign to many embedded engineers. It focuses on the PIC18 family of MCUs, and low-cost single-IC solutions.
