Forest Electronic Developments PIC C Compiler & WIZ-C Compiler
Manual for version 17 onwards - June 2010

THE FED C Compiler (WIZ-C) is intended for all serious programmers of the PIC who would like the convenience of a high level language together with the speed of assembler. With our C Compiler you no longer have to worry about ROM and RAM paging, you can call to a depth limited only by RAMnot by the 8 level call stack, use 16 and 32 bit arithmetic types for full precision, and use any of our standard library routines for general purpose data handling and interfacing. The professional version adds multiple project management and simulation and includes many additions to general simulation capabilities
The program, and its support files and example programs are © Copyright RobinAbbott, 1999. With thanks to Marcel Van Lieshout for good work on the pre-processor (2004) The program may be installed onto the hard disk of one Personal Computer, and must removed by deleting the executable file, and all the support files before installing onto a different computer. The sole exception to this is where a single user installs on two machines (e.g. Work and Laptop) on which the Forestnever be used simultaneously. program will Electronic Developments

.1 Compiler Introduction
.1.1. Information
THE FED C Compiler is intended for all serious programmers of the PIC who would like the convenience of a high level language together with the speed of assembler. With our C Compiler you no longer have to worry about ROM and RAM paging, you can call to a depth limited only by RAM not by the 8 level callstack, use 16 and 32 bit arithmetic types for full precision, and use any of our standard library routines for general purpose data handling and interfacing. WIZ-C adds a drag and drop interface, WIZ-C includes all the functionality of the FED PIC C Compiler and any reference to the FED PIC C Compiler refers to WIZ-C equally. The FED PIC C compiler will handle any of the current 14 bit PIC's andfuture devices may be added by changes to initialisation files which will be provided free of charge on our web site. All devices are handled by standard C header files. Features : • • • • • • • • • Designed to ANSI C Standards Integrated Compiler Environment Integrated Debugging Support Supports full range of 14 bit PIC Processors Efficient code production Wide range of library functions Includesfloating point numeric support Includes fully integrated assembly level debugger Supports MPLAB

The compiler also includes full inline and infunction assembler support and is supplied with full manuals and examples on CD-ROM. The enhancements which are available in The Professional Version allow the user to: • Manage and simulate multiple projects together • Connect PIC pins across projects toallow simulated devices to communicate • Handle assembler and C projects • View variables in native C format • View a list of all local variables and their values • Maintain a history within simulation to back track and determine the past leading up to an event Please note enhancements available in The Professional Version are shown in the section at the end of this manual.
