5. SOFTWARE REFERENCE
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 single-board computers and other
single-board computers based on the Rabbit microprocessor.
Chapter 4 provides the libraries and function calls related to the
RCM2200.
5.1 More About Dynamic C
Dynamic C has been in use worldwide since 1989. Dynamic C is specially designed for
programming embedded systems, and features quick compile and interactive debugging.
A complete reference 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
RAM included on the RCM2200. The flash memory and SRAM options are selected with
the Options > Project 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 developed 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. Due to the volatility of
the flash memory market, the RCM2200 and Dynamic C were designed to accommo-
date flash devices with various sector sizes.
RCM2250 and RCM2260 RabbitCore modules have two 256K flash memories. By default,
Dynamic C will use only the first flash memory for program code in these RCM2250 and
RCM2260 RabbitCore modules. Uncomment he BIOS USE_2NDFLASH_CODE macro to
allow the second flash memory to hold any program code that is in excess of the available
memory in the first flash.
