Web 51 Development System

Since version 1.12, the development system does not use any proprietary software (no Microsoft, no Keil.. :-). All tasks are accomplished by free, open-source software tools. P-Code instructions don't need macros anymore, native P-Code support is built into the mcs51-as compiler.

/bin

Web 51 is almost entirely written in I51 assembly. The GNU binutils package was chosen for compiling source code, subsequent linking (connecting user portions with library functions) and final conversion into a programmer-friendly form.

The binutils package was enhanced to support I51 series of processors. Its main components are:

mcs51-ar GNU ar - operation on archives
mcs51-as GNU as - GNU assembler. Detailed documentation is in as.pdf from the GNUDOC package.
mcs51-gasp GNU gasp - preprocessor for assembly programs
mcs51-ld GNU ld - GNU linker. Detailed documentation is in ld.pdf from the GNUDOC package.
mcs51-nm GNU nm - lists symbols in compiled files
mcs51-objcopy GNU objcopy - copying and format conversions of compiled files
mcs51-objdump GNU objdump - displays information from compiled files (hex dump, disassembler,...)
mcs51-ranlib GNU ranlib - indexes archive files
mcs51-readelf GNU readelf - displays information from compiled files
mcs51-size GNU size - displays sizes of individual sections and total size of compiled files
mcs51-strings GNU strings - displays text strings in compiled files
mcs51-strip GNU strip - removes symbols from compiled files

The patch that adds MCS51 support to the standard binutils distribution is available for download.

Another addition to binutils converts binary files into Intel HEX.

bin2hex.exe converts binary files into Intel HEX format

Source code of bin2hex is available in the download section.

UNIX-like utilities commonly used in Makefiles were added to the DOS32 version (runs under W9x,...). Linux version contains links to their usual locations (tested on Debian).

bash GNU Bourne-Again SHell, DOS32 version of the UNIX command shell. Detailed documentation is in bash.html from the GNUDOC package.
make GNU make - DOS32 version of the UNIX make utility. Detailed documentation is in make.html from the GNUDOC package.
perl interpreter
rm GNU rm - DOS32 version of the file removing UNIX utility

Linux versions of mcs51-* and bin2hex were compiled and tested under Debian version 2.2 (Intel). DOS32 versions were compiled with DJGPP under Windows 98.

The above mentioned utilities are a part of the BINxx package.

Directory /bin may contain another utilities for ISP as well.

/bin also contains Perl scripts from the GNUxx package. These are:

html2db.pl Perl script that converts html/jpeg/gif... to assembly, so that they can be compiled by mcs51-as or a51 (Keil/Intel). It is described in the WWW docs - section html2db.pl.
ip2hex.pl Perl script that generates ip.inc. It is described in the WWW docs - section mac2hex.pl and ip2hex.pl
mac2hex.pl Perl script that generates ether.inc. It is described in WWW docs - section IP and MAC address conversion using mac2hex.pl and ip2hex.pl

/include

8019.inc definitions of Ethernet, IP, TCP,... constants, RTL8019 registers, ...
param.inc basic definitions of the HW and SW environment for compilation
param.23 param.inc for which the libk23 and libw23 libraries were compiled. When using example libraries libx23, it can be renamed to param.inc.
param.80 param.inc for which the libk80 a libw80 libraries were compiled. When using example libraries libx80, it can be renamed to param.inc.

/lib

This directory contains libk and libw libraries used by the WEB51 development system, system kernel and a script that links individual modules and libraries into the final program.

(libk.a) User-compiled kernel library libk
libk23.a Standard libk library supplied with the system, compiled with support for 2 TCP stacks, active connection establishing for stack no. 1, and serial line support.
libk80.a Standard libk library supplied with the system, compiled with support for 1 TCP stack, no serial line support.
(libw.a) User-compiled libw library of arithmetic, logic, I/O, and other functions (work lib)
libw23.a Standard libw library supplied with the system, compiled with support for 2 TCP stacks, active connection establishing for stack no. 1, and support for serial line.
libw80.a Standard libw library supplied with the system, compiled with support for 1 TCP stack, no serial line support.
web51.asm Source code of the system kernel
(web51.obj) User-compiled system kernel
web51_23.obj Basic kernel (2TCP/...) compiled with standard settings
web51_80.obj Basic kernel (1TCP/...) compiled with standard settings
www51.sc Script that controls the mcs51-ld linker, ensuring proper linking of modules, libraries and other parts into the final code
Makefile that controls the build process of libraries and web51 module

/cgi

Contains a library of CGI scripts for your HTML pages. Contains source code as well as binaries, in the distribution version compiled for use with libx80 settings.

/projekt

This directory contains a set of example applications that demonstrate WEB51 programming. We recommend to store your own applications in this directory, too. The basic set of applications is described here.

FULL version of the development system is on the CD distributed with the Web 51 kit, which you can order here. Files in the FULL version of the development system are distributed under a proprietary licence that is a part of the development kit.

Free version of the development system is available for download as a RAR or TAR archive. All source codes contained in it are distributed under the GNU General Public License. If you would like to obtain a different licence, e.g. to use the sources in a commercial project, use the FULL/LITE version or contact the author.
