Installing an Infrared Remote Control on the IR100

(First contribution, could someone please fix the formatting it's a bit messed up)

This applies to all Reciva radios, not just the IR100.

For a remote control to work there must be a suitable IR sensor fitted and a lircd configuration file. That's it!

• Adding an IR sensor
• Configuration to enable control
• Using a Reciva remote control
• Using any remote control
• Diagnosing problems

• Adding a sensor

For radios that don't already have an IR sensor some hardware modifications will be required to fit one in the case where it will be visible. Almost any IR decoder that will run from a 3.3V supply should work, these devices remove the 38kHz carrier and output a logic signal that the Barracuda board can directly decode.

Some suitable sensors available from RS components are:

TSOP34838 (RS 700-5308)

TSOP1138 (RS 708-5550)

TSOP31238 (RS 570-578)

GP1UX301QS (RS 666-6542)

Check the pin-out for whichever model you use - they're not all the same. Connections to the radio are:

Decoded signal - GPG6 (JP1, pin 5) Vcc / Supply - 3.3V supply (JP1, pin 14) Gnd. (JP1, pin 9)

Pin numbers refer to the Barracuda board itself. It's probably best to solder the wires to the main board inside the radio, rather than directly to the barracuda board so that it can be removed if necessary. Carefully check the connections to make sure the correct pins are used and nothing gets shorted out!

A 47nF ceramic or polyester decoupling capacitor connected across the supply pins at the sensor end of the wires is probably a good idea.

• Configuration to enable control

For the radio to respond to an IR remote control a lircd configuration file is required in the /etc/config/ directory. The file must be named lircd_configXXXX.conf where the XXX is replaced with the radio's hardware ID. For a Logik IR100 this would be lircd_config1012.conf

• Using a Reciva remote control

If you have a remote control that works with an existing Reciva radio you can simply copy the file for that, renaming it with your radio's hardware ID. It has been reported [1] that a One for all universal remote control set up with code 0435 will work with an MX200i so use this with a Logik IR100 you would need to do this in a root terminal (login as admin):

Enable write access:

# mount / -orw,remount

Copy existing config file:

# cp /etc/config/lircd_config825.conf /etc/config/lircd_config1012.conf

Disable write access again:

# mount / -oro,remount

and reboot:

# reboot

And everything should work! No changes are required to the /root/hwconfig/configXXXX.txt file.

• Using any remote control

It should be possible to use any remote control using a suitable configuration file. Check http://www.lirc.org/remotes to see if details for your remote control are available or use irrecord, part of lircd available on linux and probably windows, to create a new file.

I've used a One for all URC-3920 programmed for code 02230 to make this lircd_configXXX.conf file:

# Please make this file available to others

The top of the file describes the characteristics of the remote - timings etc. The codes section translates a remote control code into a single character that the radio decodes as a button.

Note that the version of lircd in the Reciva software doesn't seem to understand the toggle_bit_mask command so this may need to be changed to the equivalent toggle_bit (0x0 will become 0, and for RC5 0x800 will become 2).

The list of available options is:

• Diagnosing problems

If the remote control doesn't work restart lircd from the command line and see what it outputs. To restart it is first necessary to stop any running instance of lircd.

Find the process number using:

# ps -A | grep lirc

This should give an output something like:

 102 root      1464 S <  /usr/sbin/lircd -d /dev/lirc/0 /etc/config/lircd_conf
 133 root      2280 S    grep lirc

In this case the number we need is 102, so:

# kill -9 102

and then simply:

# lircd

and see what errors are shown, hopefully they're meaningful.
