To facilitate software development, nearly all ELZET80-boards use a TLCS900-family microcontroller.
To program this processor in the "C" language from your MS-DOS-PC requires a so called "Cross- Compiler" , i.e. one that runs on an 80x86 type processor (your PC) and produces code for a TLCS900 (your industrial hardware).
To encourage the use of the TLCS900, TOSHIBA offers for free a version of the ANSI-C-Compiler with limitation of 3000 lines. For the professional user there is also a full version of the ANSI-C at an attractive price.
To write a program to run on for instance the TSM-CPU900 under mCAT, it requires the steps in the table at the left side. The shaded section is covered by the tools in TOSHIBA´s C-Compiler packages, a downloader is part of mCAT and of most standard terminal programs.
ANSI-C-Cross-Compiler
- Optimizing ANSI-Cross-C-Compiler for the TLCS900 running under MS-DOS.
- Supports 64/80bit floating point operations, #pragmas for stack checking, argument passing, and loop optimization.
- Special functions are provided for interrupt processing and immediate assignments to processor registers.
