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 RCM3365/RCM3375.
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 RCM3365/RCM3375. 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:
An application should be run from the program execution SRAM after the serial
programming cable is disconnected. Your final code must always be stored in flash
memory for reliable operation. RCM3365/RCM3375 modules running at 44.2 MHz
have a fast program execution SRAM that is not battery-backed. Select
Code and
BIOS in Flash, Run in RAM
from the Dynamic C
Options > Project Options >
Compiler
menu to store the code in flash 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 RCM3365/RCM3375 modules running at 44.2 MHz.
NOTE:
Do not depend on the flash memory sector size or type in your program logic.
The RCM3365/RCM3375 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 2000/NT and
later—see Rabbit’s Technical Note TN257,
