Programming with SIMPL Windows
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows®
environment.
SIMPL Windows is Crestron Electronics' software for programming Crestron
control systems. It provides a well-designed graphical environment with a number
of workspaces (i.e., windows) in which a programmer can select, configure,
program, test, and monitor a Crestron control system.
The next two subsections describe a sample SIMPL Windows program that utilizes
the CNXVTC-3. The first subsection details how the sample program works with a
textual description and block diagram. The second subsection provides a broad
description of how to actually create the SIMPL Windows program.
NOTE:
The following description assumes that the reader has knowledge of
SIMPL Windows. If not, please refer to the extensive help information provided
with the software.
NOTE:
There is no need to recreate the sample SIMPL Windows program. A copy
of this program is available from Crestron’s ControlCD (version 4.03 and later).
Search for the CNXVTC-3.SMW project in the SIMPL Windows Example Base.
How the Program Works
A basic CNXVTC-3 SIMPL program is shown on the next page in block diagram
form. For this example, the CNXVTC-3 occupies slot #1 of a CNMSX-PRO.
Assume channels A and B are tied together to provide control over a stereo source
that has a left and right channel. Channel C is for a mono source that only has one
channel, such as a microphone.
