Dynamic C is an integrated development system for writing
embedded software. It runs on a Windows-based PC and is
designed for use with single-board computers and other devices
based on the Rabbit microprocessor. Chapter 5 describes the
libraries and function calls related to the RCM5400W.
5.1 More About Dynamic C
Dynamic C has been in use worldwide since 1989. It is specially designed for program-
ming embedded systems, and features quick compile and interactive debugging. A com-
plete reference guide to Dynamic C is contained in the
Dynamic C User’s Manual .
You have a choice of doing your software development in the flash memory or in the static
SRAM included on the RCM5400W. The flash memory and SRAM options are selected
with the
Options > Program Options > Compiler
menu.
The advantage of working in RAM is to save wear on the flash memory, which is limited
to about 100,000 write cycles. The disadvantage is that the code and data might not both
fit in RAM.
NOTE: Do not depend on the flash memory sector size or type in your program logic.
The RCM5400W and Dynamic C were designed to accommodate flash devices with
various sector sizes in response to the volatility of the flash-memory market.
Developing software with Dynamic C is simple. Users can write, compile, and test C and
assembly code without leaving the Dynamic C development environment. Debugging
occurs while the application runs on the target. Alternatively, users can compile a program
to an image file for later loading. Dynamic C runs on PCs under Windows NT and later—

be downloaded at baud rates of up to 460,800 bps after the program compiles.
