Repeater LIRC Configuration

Setting Up the Key Codes

Use your Ryde receiver to record the key codes from the IR sender for your HDMI switch. To do this you will need to install additional software, but it will not affect future operation of your Ryde.

Install and edit lirc

1. Log in to the Ryde by ssh and type "stop" and press enter. The Ryde should stop receiving.

2. Type "sudo apt-get -y install lirc" and press enter.

3. Type "sudo nano /etc/lirc/lirc_options.conf" and press enter. Edit the following 2 lines:

driver          = devinput
device          = auto

to read:

driver          = default
device          = /dev/lirc0

press ctrl-x, then y and enter to exit from the editor.

Check IR commands are being read

4. Enter "systemctl stop lircd.service" and press enter. The Ryde will ask for authentication with your password. By default this is raspberry.

5. Now enter "mode2 -d /dev/lirc0" and press enter. Try pressing the buttons on your HDMI switch remote and you should see a stream of "pulse", "space" and "timeout" messages. This shows that the configuration is correct. press ctrl-c to exit.

6. Enter "systemctl start lircd.service" and press enter. The Ryde will again ask for authentication with your password. By default this is raspberry.

Create config file for your remote

7. Now you can create a configuration file for your remote. This is a complex process and you might need a couple of attenpts to get it right. Enter "irrecord" and press enter.

Read the message (if you want) and then press RETURN (enter)

Once the app has checked for ambient light, enter the name of the remote in the format "brand_name_hdmi" and press enter.

Then read the message about pressing buttons, grab your remote and press enter. Start recording buttons - this may take a minute or 2.

The next step will be to enter names for each key and then press the key. Use the approved names in the table below. You only need to enter the keys that you are going to use.

Lastly, the app will ask you to press an arbitary button "for the toggle mask", and will then tell you the filename and exit.

8. Open the "xxxxx_hdmi.lircd.conf" file with a text editor (nano?) and check that there are non-zero entries against the keys. If it looks like they are all zero, you will need to repeat the process (just Step 7).

9. You need to copy the "xxxxx_hdmi.lircd.conf" file from your Ryde to your repeater RPi, and then use the command

sudo cp /etc/lirc/lircd.conf.d /etc/lirc/lircd.conf.d//etc/lirc/lircd.conf.d

to copy it to the right place.

10. After that, on your Repeater RPi, either reboot or enter "systemctl restart lircd.service" and enter your password.

To set up the repeater to use the codes, you need to set the remote control name and the actual key names in the repeater config file. More info to follow.

The recommended list of key names is as follows:

Key Name	Function
KEY_POWER	HDMI Switch on/off
