/dev/lirc0 Missing Raspberry Pi
and with mode2 i get an error like "error opening /dev/lirc" when i have all the modules loaded needed. how do i get a "/dev/lirc" needed to run mode2?

I also can't get it to send anything either (as confirmed by looking at the led through a digital camera). What am I doing wrong? NephusOctober 12th, 2008, 12:15 AMwell, found out why it wasn't working, the version that installs with apt-get doesn't include support for iguanaIR even though it lets me select the device during install. So, I tried to manually build a version that did. Now I've got a half install that I can't find and /etc/init.d/lirc start doesn't do anything. half the commands aren't found, but if I use sudo they run for some odd reason. I'm really pulling my hair out here, does anyone have some advice? NephusOctober 12th, 2008, 01:44 AMok, new status update in case anyone has any advice from this point on. Figured out what's wrong when I use make to build from source. I
use my home-brew receiver and transmitter on the same serial port? Yes. The value of the resistor in the receiver circuit is labeled as '4k7' Ohm. Is this 4.7 Ohm, 4.7 kOhm http://www.lirc.org/faq.html or what? 4k7 Ohm means 4700 Ohm. k is the abbreviation of kilo.

No, this won't work. But there is a project working on a dedicated USB transceiver or you can connect an IR receiver to a FTDI based USB chip. Using an Irman with USB adapter should work though. I have a Hauppauge TV card. Can I use could not a different remote control with this TV card except the original Hauppauge remote control? The Hauppauge remote control uses the RC-5 protocol. You should be able to use any TV remote control that uses this protocol. Common brands that use this protocol are Philips and Marantz. A short description how to setup LIRC with an universal remote control was posted on the mailing list. How do the drivers for the home-brew receivers work? could not get Do they use polling? No, the serial port driver is fully interrupt driven. On each edge of the IR signal the interrupt handler is called and the time since the last interrupt is calculated. As the parallel port only generates interrupts on the rising edge of the input signal, the parallel port driver uses polling with the help of the hardware timer until the signal becomes low again. As it is polling only for microseconds this has no noticeable effect on system performance. I would like to connect an LCD display and an home-brew IR receiver to the same serial port. Will this work? No, unless somebody writes a driver that merges the functionality of the kernel serial port driver and the lirc_serial driver. This is not trivial. I need a IR transmitter device to control my TV/VCR/Settop box. But I'd rather buy a device than solder my own. Where can I buy LIRC compatible transmitters? Check the driver documentation in the configuration guide. Here is several commercially available devices including IrToy, IguanaIR and Tira. I need a IR transmitter device to control my TV/VCR/Settop box. But I'd rather buy a device than solder my own. Where can I buy LIRC compatible transmitters? You can buy serial port or USB transceivers at www.irtrans.de. They provide a LIR
