5. SOFTWARE REFERENCE
Dynamic C is an integrated development system for writing
embedded software. It runs on an IBM-compatible PC and is
designed for use with Rabbit Semiconductor single-board com-
puters and other single-board computers based on the Rabbit
microprocessor. Chapter 4 provides the libraries and function
calls related to the RCM2100.
5.1 More About Dynamic C
Dynamic C has been in use worldwide since 1989. Dynamic C is specially designed for
programming embedded systems, and features quick compile and interactive debugging in
the real environment. A complete reference to Dynamic C is contained in the Dynamic C
User’s Manual.
Dynamic C for Rabbit
®
processors uses the standard Rabbit programming interface. This
is a 10-pin connector that connects to the Rabbit Serial Port A. It is possible to reset and
cold-boot a Rabbit processor via the programming port. No software needs to be present in
the target system. More details are available in the Rabbit 2000 Microprocessor User’s
Manual.
Dynamic C cold-boots the target system and compiles the BIOS. The BIOS is a basic pro-
gram of a few thousand bytes in length that provides the debugging and communication
facilities that Dynamic C needs. Once the BIOS has been compiled, the user can compile
his own program and test it. If the BIOS fails because the program stops running, a new
cold boot and BIOS compile can be done at any time.
The BIOS can be customized by using #define options.
Dynamic C does not use include files, rather it has libraries that are used for the same
purpose, that is, to supply function prototypes to programs before they are compiled. See
Section 4.24, “Modules,” in the Dynamic C User’s Manual for more information.
Dynamic C supports assembly language, either as separate functions or as fragments
embedded in C programs. Interrupt routines may be written in Dynamic C or in assembly
language.
