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 Semiconuctor controllers and other

controllers based on the Rabbit microprocessor. Chapter 5

describes the libraries and function calls related to the

RCM3750.

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 RCM3750. 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 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 RCM3750 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.
