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 CNXMIDI. 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 is familiar with 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 5.1 or later).

Search for the CNXMIDI.SMW project in the SIMPL Windows Example Base.

How the Program Works

A basic CNXMIDI SIMPL program is shown in block diagram form below. For this
example, the CNXMIDI occupies slot #1 of a CNMSX-PRO. This example plays
three notes on a MIDI keyboard. A note is turned on for 0.05s and then there is
silence for 0.05s before the next note is played. The sequence is triggered when a
certain note is received from the keyboard, and stopped at the end of the sequence.

How to Create the Program

Configuration Manager

Use the Configuration Manager workspace in SIMPL Windows to select and

configure all the devices that need to be included into the system. For this example,

add a CNXMIDI to slot #1 of the control system, shown below.

NOTE: SIMPL Windows v1.21.03 or later is required to program the CNMSX-AV

or PRO with a CNXMIDI card. If using an earlier version of SIMPL Windows,

Crestron recommends a SIMPL Windows and operation system upgrade. The latest

version can be obtained from the Software Downloads page of Crestron’s website

(www.crestron.com). New users are required to register in order to obtain access to

the FTP site.

and assign their respective signals. Expand the Network Module folder and expand

the CNXMIDI. Double click on the ST-LT/MIDI serial driver to view it in detail

view (alternatively CTRL+D), as shown on the next page.
