CRESTRON
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 CNXVGA. The first subsection details how the sample program works with a
textual description. 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 touchpanel or SIMPL Windows
program. A copy of each is available from Crestron’s ControlCD (version 5.1 and
later). Search for or CNXVGA2.VTP and CNXVGA2.SMW projects in the SIMPL
Windows Example Base directory.
NOTE:
SIMPL Windows v1.21.04 or later and CNXVGA firmware v1.26 or
higher are required to program a control system containing the newly improved
CNXVGA symbol. This new CNXVGA symbol must replace the CNXVGA symbol
in programs created with earlier versions. The out-dated CNXVGA symbol appears
in updated programs with a “CNXVGA OLD” heading. Keep in mind that inputs
and outputs to the old and new CNXVGA symbol are not directly compatible and
older programs may need to be reworked.
How the Program Works
The example program demonstrates how to use the CNXVGA and its associated
functions within a system. The core program is based around the network definition
for the CNXVGA. The following is a brief explanation of the CNXVGA network
definition implementation.
CNXVGA Input Parameters
RGB, Video, Out_disable:
The
RGB
and
Video
are used to select which input
source should be displayed on the output using a momentary activation on the input.
Out_disable
can be used to “mute” the output and is typically driven off a toggle.
In_Adj, Out_Adj:
The input adjust allows the user to position and size each RGB
image to best fit within the boundaries of the display. The
Out_Adj
is not typically
needed when you use the CNXVGA to display on either the VT-3500 or VT-3500L
touchpanels. If some other display device is used, it may be necessary to define the
visible area of the screen. The
Out_Adj
allows adjustments to be made. All
incoming signals and presets stored after making the adjustment will conform to the
