About:

IRpet is a small set of tools to help examine, and visualize IR streams. It uses LIRC (specificaly mode2) to get the “raw” input streams

IRpet comes in four pieces:

• irpet - Runs the grabber and the graphing pieces, and creates a HTML report
• irpet-grabber - Script to loop and grab buttons. Can be used to grab several remotes, and several passes
• irpet-graph - Generate histogram, and a 3d graph of each stream
• irpet-simulator - simulator based on initial button grabs. Basically just takes the output from previous runs, and outputs random buttons to STDOUT. Can be used for testing other programs that use mode2 input (like SurveySays, also from MRL, =)

TODO - irpet-bitstream - take input, and make a bitstream out of it given parameters.

Downloads, etc

• “Source” irpet-0.2.tgz
• Debian package irpet_0.2-1_i386.deb
• RPM package irpet-0.2-1.i386.rpm
• Here’s an example of the HTML output from irpet that includes a histogram, and a 3d graph for each IR stream

Requirements:

• Linux system Tested on Debain, and Redhat - let me know if you get it working on other systems (no reason I know of why it wouldn’t work).

• perl Most likely already on any of the previously mentioned systems. You might need to install the GD::Graph module. Everything else should be standard AFAIK

  On Debian:
          apt-get install libgd-graph3d-perl
  
  
  Or in general:
          perl -MCPAN -e 'install GD::Graph::bars3d'<br />
          (You only need .gif support, so you don't necessarily have to
          build support for all image types (you might get errors if it
          doesn't match what GD was built with)).  Note: if you install
          this module manually like this, you'll need to install the rpm
          with --nodeps to get it to install.
  

• LIRC (configured) This is available from www.lirc.org. Usually this is the biggest hurdle to getting it all working. Basically, if you can get the mode2 binary to give valid output, this should work as well.

• IR Hardware compatible with LIRC

Usage:

irpet:
usage: ./irpet -b {num of buttons} [options]
        -d {output directory} default cwd
        -p {number of passes} default 1
        -r {number of remotes} defualt 1
        -V {vertcal resolution of images} defualt 600
        -H {horizontal resolution of images} defualt 800
        -v gives more verbose output
        -h :help

irpet-grabber:
usage: ./irpet-grabber -b {num of buttons} [options]
        -d {base output directory} defualt is current dir
        -p {number of passes} default 1
        -r {number of remotes} defualt 1
        -v gives more verbose output
        -h :help

irpet-graph:
usage: ./irpet-graph -i {input file} [options]
        -V {vertical resolution of images in pixels} 600 by default
        -H {horizontal resolution of images in pixels} 800 by default
        -p {file prefix} "irpet-" by default
        -w {histogram width} 100 by default
        -r :use this if you want pulses and spaces reversed in the graphs
        -h :help

        example: ./irpet-graph -i remote1button5.mode2.out -v 768 -H 1024 -p mydir/test
        This will produce 3 images with 1024x768 pixels:
                test-pulses-histogram.gif
                test-spaces-histogram.gif
                test-graph.gif

irpet-simulator:
usage: ./irpet-simulator {input files} [options]
        -s {seconds of delay between "presses"}
        -b {number of buttons to simulate}
        -h : help

        example: ./irpet-simulator -s 2 -b 4 pass?/remote*button*
        This will take all of the files and randomly spit 4
        of them out on STDOUT with a delay of 2 seconds
