ROGRAMS

To help familiarize you with the RCM2000 modules, several
sample Dynamic C programs have been included. Loading, exe-
cuting and studying these programs will give you a solid hands-
on overview of the RCM2000’s capabilities, as well as a quick
start with Dynamic C as an application development tool.

4.1 Sample Program Overview

Dynamic C comes with a large number of sample programs that illustrate many of its fea-
tures. These programs are intended to serve as tutorials, but then can also be used as start-
ing points or building blocks for your own applications.

NOTE:

It is assumed in this section that you have at least an elementary grasp of ANSI C.

If you do not, see the introductory pages of the

Dynamic C User’s Manual

for a sug-

gested reading list.

Sample programs are provided in the Dynamic C

Samples

folder, which is shown below.
