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 RCM3900. 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.
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 and later—see

additional information if you are using a Dynamic C release prior to v. 9.60 under Windows
Vista. Programs can be downloaded at baud rates of up to 460,800 bps after the program
compiles.

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 controllers and other controllers
based on the Rabbit microprocessor. Chapter 5 describes the
libraries and function calls related to the RCM3900.

programming cable is disconnected. Your final code must always be stored in flash
memory for reliable operation. RCM3900 modules have a fast program execution SRAM
that is not battery-backed. Select
Dynamic C
and copy it to the fast program execution SRAM at run-time to take advantage of the
faster clock speed. This option optimizes the performance of RCM3900 modules run-
ning at 44.2 MHz.
The RCM3900 and Dynamic C were designed to accommodate flash devices with
various sector sizes in response to the volatility of the flash-memory market.
