I am trying to set up a simple serial receiver that would work with my
TV remote control . But I am stuck at one point and , although searched
a lot through the web, followed all basic and advanced recommendations,
I must admit I can not make it work for the moment Sad
I have soldered the simple serial receiver from lirc.org on my VIA EPIA
800, taken care about the recommendations on the low supply voltage
provided on those motherboards. So I am almost sure the hardware is
Have you checked the circuit with a multimeter or scope? Check
the regulator output is 5v, the output of the receiver should toggle
when it sees a signal.
Yes I have checked the circuit with multimeter.
The regulator output is 6.15 V, it is external, since I dont have
enough voltage on the RTS pin from my VIA EPIA board (only 4V).
When I check the receiver output, I have a 4.04V toggling when I press
remote button downto 3.04 V.
For me, this means that the circuit is ok.
I agree with you that it should be recognized as an active low
I then followed a wiki lirc howto
I have found my Sony remote control in the - excellent - remote config
site from lirc.org (http://lirc.sourceforge.net/remotes/), loaded my
lircd.conf at the right place.
but ... no way ! when I come to mode2 attempt : nothing reacts , as if I
had nothing on the serial port Evil or Very Mad
Here are my logs :
root@mythtv:/home/mythtv# dmesg | grep lirc
lirc_dev: IR Remote Control driver registered, at major 61
lirc_serial: auto-detected active high receiver
lirc_dev: lirc_register_plugin:sample_rate: 0
Most receivers are active low type: the output is normally high
and is pulled low when it sees IR signal. I have not come across
a active high receiver, most are active low. So this could
indicate your circuit is broken.
But still dont know what to do to repair it ...
Other ideas ?
