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 with controllers based on the Rabbit
microprocessor Chapter 5 provides the libraries and function
calls related to the RCM3209/RCM3229.
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 in the real
environment. A complete 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 data
SRAM included on the RCM3209/RCM3229. The flash memory and SRAM options are
selected with the

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: An application should be run from the program execution SRAM after the pro-
gramming cable is disconnected. Your final code must always be stored in flash memory
for reliable operation. For RCM3209/RCM3229 modules running at 44.2 MHz, which
have a fast program execution SRAM that is not battery-backed, you should select

execution SRAM at run-time to take advantage of the faster clock speed. This option
optimizes the performance of RCM3209/RCM3229 modules running at 44.2 MHz.
NOTE: Do not depend on the flash memory sector size or type. Due to the volatility of
the flash memory market, the RCM3209/RCM3229 and Dynamic C were designed to
accommodate flash devices with various sector sizes.
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 2000/NT and later—
