Overview

Using the pigpio library, this repository will test the IR sensor & IR emitter of your MATRIX Creator by recording and playing back an IR signal you give it.

The example in this repository is taken from the IR Record and Playback pigpio example.

Setup

This guide will be utilizing pins 13 & 16 of the Raspberry Pi. These pins are connected to the MATRIX Creator's IR transmitter & IR receivers, respectivly. For reference, below is an image of the Raspberry Pi GPIO connected to the MATRIX Creator.

1. Installing the MATRIX Dependencies

Keep in mind, that installing any of the MATRIX Programming Environments will also include these MATRIX Dependencies.

Run the following commands in your Raspberry Pi's terminal to add the MATRIX repository & key and update your repository packages.

curl https://apt.matrix.one/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.matrix.one/raspbian $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list

Update your repositories and packages.

sudo apt-get update
sudo apt-get upgrade 

Install the MATRIX Creator init package.

sudo apt-get install matrixio-creator-init 

Reboot your Raspberry Pi.

sudo reboot

2. Installing pigpio

Once your Raspberry Pi has finished rebooting, go back into the terminal and run the following command to install pigpio.

sudo apt-get install pigpio

You will also need to install the python dependency with pip.

pip install pigpio

3. Downloading the IR Test

You'll need to install git, if you havn't already.

sudo apt-get install git

With all the required dependencies installed, you can now run the following commands to clone this repository in your Raspberry Pi.

cd ~/
git clone https://github.com/matrix-io/matrix-creator-ir-test
cd matrix-creator-ir-test

4. Running the IR Test

When running this test you'll need to start the pigpio process.

This must be done each time your Raspberry Pi boots.

sudo pigpiod

Below are the test commands you can run.

• Record: This command allows you to specify the names of each IR signal you want to record. The command below will ask for 2 IR signals to signify the channel_up & channel_down and store them in a local file named ir_codes.json.

python ir_remote.py -r -g16 -f codes.json channel_up channel_down

• Playback: This command allows you to play any IR signal recorded with the previously mentioned command. The command below will play the IR signal that was stored as channel_up in codes.json

python ir_remote.py -p -g13 -f codes.json channel_up
