This application note details the Microchip TCP/IP stack, a software library designed for Microchip PIC18 series microcontrollers. It explains the stack's architecture based on the TCP/IP reference model and its implementation using cooperative multitasking techniques to operate independently of the host application's operating system.
The document provides guidance on configuring the stack using C compiler directives, such as enabling or disabling specific modules like TCP, UDP, and HTTP. It also includes a complete example of an HTTP server application written in C, demonstrating how to integrate the stack into a user program. This manual is written in Chinese.
