Basic Scripting

These sort of commandir_send commands can easily be scripted into .bat files on Windows or .sh files on Linux:

Sample Windows .bat file:

Use CommandIR Utilities - simple command-line programs - to control devices from your PC via CommandIR in your own projects on a local machine or over a network.  

Record and transmit IR codes, create scripts, and respond to PC events all using CommandIR and our cross-platform Utilities!

Basic Use - Recording and Transmitting IR Codes in Files

Note: All commands are identical on Windows and Linux.

First, record any remote control commands you want to use from the PC via CommandIR (or locate the IR codes from an online database):

C:\> commandir_record my_amplifier_volume_up

After recording the Volume Up key for an audio amplifier as 'my_amplifier_volume_up', run

C:\> commandir_send -e2 my_amplifier_volume_up

to transmit it on Emitter #2.  Emitter #2 should be placed over the IR receiver on the amplifier for it to receive the command from CommandIR.  The amplifier will respond as if the original remote button had been pressed. 

The -e parameter is used to set which emitter to transmit on.  All channels will be used if -e is not specified.

The -b parameter can select multiple emitters at once using a bitmask.  See the full commandir_send manual page for details.

Basic Use - Using Hex Codes

CommandIR Utils use the same "hex code" format as the Remote Central IR Hex Codes Database.

IR codes are easiest to track and organize when stored in files, but they need not be.  Use commandir_record with the -d display option to only view IR codes as they are detected:

support@commandir:~$ commandir_record -d

commandir_record 1.00-pre3

Initiating with 1 CommandIR.

Press buttons on your remote now, and press 'enter' (or Ctrl+C) on the keyboard to quit.

Basic Scripting - Sending Control Commands

@echo off 

:: power_device.bat 

:: Toggle power on all my devices
commandir_send -e1 tv_power
commandir_send -e2 dvd_power
commandir_send -e3 receiver_power
commandir_send -e4 sat_box_power 

Sample Linux .sh file:

#!/bin/bash
# volume_up.sh
# Turn up the volume on my external receiver (send twice)
commandir_send -e3 receiver_volume_up receiver_volume_up 

The commandird daemon shares and coordinates CommandIR activity between multiple programs and clients, and provides networking support. 

Without commandird, a race condition will occur if two or more commandir_send need to happen at the same time - for example, power control and volume - one will claim the CommandIR and succeed, the other will see the CommandIR as 'busy' and fail.

commandird queues up signals and can maintain connections with many clients at once. Commands will never be lost if commandird is used.
