Dynamic C is an integrated development system for writing
embedded software. It runs on an IBM-compatible PC and is
designed for use with Z-World single-board computers and other
single-board computers based on the Rabbit microprocessor.
Chapter 5 describes the libraries and function calls related to the
RCM3600.
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 and in
the Dynamic C Function Reference Manual .
You have a choice of doing your software development in the flash memory or in the
SRAM included on the RCM3600. The flash memory and SRAM options are selected
with the
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: An application can be compiled in RAM, but cannot run standalone from RAM
after the programming cable is disconnected. All standalone applications can only run
from flash memory.
NOTE: Do not depend on the flash memory sector size or type in your program logic.
The RCM3600 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 95 and later.
Programs can be downloaded at baud rates of up to 460,800 bps after the program
compiles.
