4) 68hc11 PRODUCTS


    This section includes descriptions and references to free and
    commercial software for the 68hc11.  FTP sites and BBSs contain many
    quality packages and code samples for free.  For heavy duty use, you
    might prefer the many commercial packages that are available.  Some
    very high quality, low-priced packages are available which are
    suitable for both the hobbyist and professional on a limited budget.
    With the public domain (or free) stuff, you're usually on your own.
    The commercial packages usually provide extensive documentation and
    support.


4.1) Free languages and development tools


    The following is a list of the languages and development tools that I
    could find on the net.  Nearly all of them include source code,
    however not all are public domain.

      Program: asxxx-v1.51-beta.tar.gz
      Description:  This is an updated version of the ASXXXX
                    cross-assembler package written by Alan R. Baldwin of
                    Kent State University.  This version includes the
                    following changes:
                      - Port to Unix and Unix-like OS's
                      - Support for ar(5) style libraries in the linker
                      - Improved code area management
      Comments:  This is the assembler back-end currently used by the
                 Coactive Aesthics gcc port; a majority of these changes
                 were made to better support the gcc port.  The current
                 distribution is a drop-in upgrade for the version
                 currently used in the Coactive gcc port.

      Comments:  Author says that for now this software should be
                 considered beta.  Although he also says that he's been
                 using it to great success for 3 years, including using
                 it to rebuild two major commercial products without
                 error.

                 Author has lost the DOS port, but claims it was fairly
                 trivial.  Mostly changing "r" to "rb" in fopen()s.

4.2) Free C compilers


    One of the big advantages of choosing the 68hc11 for your next
    project (especially you hobbyists on a low budget) is the
    availability of freeware and low cost C compilers.

    A freeware version of the Hi-Tech C compiler is available for
    evaluation and tinkering.  This compiler produces crippled assembler
    output only and does not include libraries.  A method was developed
    and uploaded to make the compiler output usable.

    I've been playing with the Dunfield Development System lately (on the
    8051), and it's really quite nice.  I've also heard many good things
    about it from others.  It includes a near ANSI-C compiler, run-time
    library with source, assembler, ROM debugger, integrated development
    environment, monitor with source, utilities, and other extras.
    Although not freeware, the low price ($100), the features, all of the
    extra goodies, and the good reviews make this a package worth looking
    at.  Also, if you're interested in working on more than one family of
    microcontroller, Dunfield supports a wide range.  This means only
    needing to learn one system, instead of many.

    Another decent C compiler comes from ImageCraft.  Version 3 is now
    shipping. It includes a near ANSI C compiler, a Windows IDE with
    integrated editor, terminal program, and the ability to operate
    compiler tools and options.  A make utility and library source are
    included along with the field proven compiler tools. Price $100. For
    more info, check out the Webpage http://www.imagecraft.com or Email
    to imagecft@best.com.
