The goal of this project is to enable the use of the computer as a generic Infra-Red remote control for all the peripheral you want, or to remotely control the computer from any IR remote control.
Inspired by "Albert's FTDI IR receiver / transmitter
", this module is USB connected and self powered.
Interface is based on FTDI FT232RL chip which is able to convert USB in some easy to use I/Os.
Design is very simple and the schematics is only made of the FTDI chip, a IR receiver (TSOP1738) selective at 38kHz (carrier most used in IR) a MOSFET transistor (a BSS138N is sufficient) to drive two IR LEDs.
IR transceiver schematics
Transceiver is made to operate with LIRC (0.9 or more)
Once module is plugged, launch LIRC daemon :sudo lircd -n -H ftdi configuration.conf
Some configuration files corresponding to your remote control are available in /usr/share/lirc/remotes/
or on lirc website http://lirc.sourceforge.net/remotes/
To send IR command, run :irsend SEND_ONCE remote_name touch_name
It is possible to make your own config file with sudo irrecord -H ftdi config.conf
and follow the instructions.
