Introduction
This modified version of the TCP/IP stack is based on the original
distribution of the Microchip TCP/IP stack v3.75.
The main goal for creating this version was to be able to have a
consistent and common source code base across different projects and
reference designs, more easy to configure, better organized and easier
to read and modify.
The original code included numerous conditional macros, and this version
added many more. While different configuration options have been tested,
given the large number of combinations there are probably some that were
not tested yet. Then the current version is released as a beta
version.
While most of the code in this version follows the same logic as the
original version, some of the differences with previous versions are the
directory structure, file names and the way the stack options and hardware
configurations are defined.
There are also some fixes and improvements, such as the LCD routines
that have been replaced with new code that includes support for a
character LCD module using the standard parallel interface or the SPI
interface using a Microchip MCP23S08 port extender.
Another addition is for example support for the new Microchip 25LC1024
1Mb serial EEPROM and better code selection to handle 24 and 32 bit
addressing.
All the source code is organized in the src
directory with subdirectories for each of the major modules, such as the
code for the TCP/IP stack in the net directory,
the LCD driver functions in the lcd directory, etc.
Each of these subdirectories also contain an
include subdirectory where the associated header files for each
module are located.
All the files went through a clean up process to improve readability and
better code organization, some definitions have been moved to other
include files, all configuration options have been moved to the main
config.h and hardware configuration files,
all the header and source code files have been reorganized in sections
and in an order such as the prototype definitions for every and each
function could be removed eliminating a substantial amount of clutter
from the source files.
All the code heritage or version log history has been preserved
but reorganized, all tabs replaced by white spaces to permit using any
text viewer or editor without loosing the indentation for easy readability.
Most of the files now follow a common editing style.
There are several modifications based on suggestions, findings and
comments from many members of the Microchip User's forum and some
ideas taken out from the latest release (v4.02) of the original
Microchip TCP/IP stack code.
Note: The current version DOES NOT support the HI-TECH or CCS compilers yet.
Thanks to all members of the Microchip Users Forum that actively
participate in the forum making great contributions and providing
countless suggestions and ideas.
A pdf version of the complete instructions is available for download
in the library page.
Happy Networking !!!
