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 single-board computers and other

single-board computers based on the Rabbit microprocessor.

Chapter 4 provides the libraries and function calls related to the

RCM2000.

5.1 More About Dynamic C

Dynamic C has been in use worldwide since 1989. Dynamic C is specially designed for

programming embedded systems. Dynamic C 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.
