Wake-On-LIRC is a small circuit that is used to replace the homebrew serial port receiver of
the LIRC project. With Wake-On-LIRC you can turn on your PC with your IR remote by sending a Wake-On-LAN pulse.
It shares the IR receiver IC (e.g. TSOP1738) as well as the Wake-On-LAN socket, so LIRC and Wake-On-LAN will remain working just as before.
For decoding the incoming RC5 or SIRCS remote control signals an Atmel AVR® ATtiny12(L), ATtiny13, or AT90(L)S2343 is used.
News: PS/2 Emulation replaces Wake-On-LAN connection
Since the Wake-On-LAN socket is considered obsolete on mainboards, the WOL connection of Wake-On-LIRC is being replaced by a PS/2 keyboard emulation. The circuit is powered by the 5 V standby voltage of the PS/2 socket. Waking up the PC is done by an emulated ACPI “Wake” key code sent to the PC's PS/2 controller. This has been tested on an Asrock A330ION mainboard and works like a charm.
The new implementation is only available via the EngDR SVN repository. If you want to use it, check out the PS/2 Emulation Branch of the Wake-On-LIRC SVN repository. Be sure to carefully read the README file as it describes the required hardware changes (no schematics drawing available yet).
- can only detect RC5 (Philips) and SIRCS (Sony, 12bit) encoded IR signals to turn on PC (contributions for other encodings are welcome!)
- ability to flash an Atmel ATtiny12(L), ATtiny13, or AT90(L)S2343 microcontroller
(I can send out controllers worldwide, with the latest firmware already installed - just have a look at the products list and write me if you have questions)
- ATX compliant PC mainboard with Wake-On-LAN support and 3pin header (for power supply while PC is turned off and on, and for power-on signal)
Changes from 0.1.2 to 0.2.0
