Post subject:  Homebrew Lirc receiver.
Ok i made a homebrew lirc receiver.. after some tinkering.. im on the finish-line.. but not quite done.

i recompile lirc
then
Code:
setserial /dev/ttyS0 UART none

now im able to modconf and add lirc_serial

when i use mode2 it sees the remote keystrokes just fine. I even used irrecord to create a new .lirc file. the only thing that doesnt work is myth. do i have to recompile mythtv inorder to have the new lirc support.. When installed knoppmyth i chose the REMOTE install..

so my homebrew works great.. and lirc compiles fine... irrecord works.. so does mode2.. myth does not. =(

irrecord isn't used to create .lircrc rather it is used to create /etc/lircd.conf. MythTV doesn't use ~/.lircrc but rather ~/.mythtv/lircrc. When it doubt, read the docs for the program you are trying to use, KnoppMyth in no way deviates from them.

i miss-spoke, however that is what i meant. i created a lircd.conf file with irrecord. I used the names from the ./myth/lirc like BLANK and such. I in no way changed the .myth/lirc file, but myth still doesnt work... hmmm i must have missed something.

I seem to have hit a roadblock. :( I cant get lirc to work. From one of my working stock knoppmyth boxes if i try

Code:
mode2


it says cant run it becase \dev\lirc is being used. On my non working box it lets me run it, that tells me that lirc is not running. Here is how i buildt my box. I recompiled Lirc using these steps
1) untar the kernel source using walkthough on forum
2) ./configure choose homebrew lirc
3)make
4)make install
5) at this point i cant modconf the module lirc_serial (which im not sure, but i should load that right? so i have to run
Code:
setserial /dev/ttyS0 uart none

6) NOw because of the previous command "setseral /dev/ttyS0 uart none" it will let me load the lirc_serial, and it will install the module

like i said input from the remote is working great using mode2. As near as i can tell lirc is NOT running .. I dont see it on TOP course i dont think top actualy shows everything, it seems to only show what the screen has room for.. I have read every howto i could get my hands on, including the FAQ on lirs website. I did the howto for the homebrew as well. Also my last thing.. i have read that people use modprobe ati_lirc (or something like that if you have an ati, what do i do if im not using an ati?)

:cry: somebody help before a grown man cries ...



ps
:D

well small update.. in all my attempts.. it started working..
i was just typeing along.. and typed
mode2
it regected me saying that /dev/licr is in use!!!!! YEAH
so i started myth and bam!i could use the remote and the homebrew receiver fine.. I have no idea what i did though.. so after testing it, i held my breath.. and rebooted.. and what i thought happened.. it stoped working again. I read about howto update-modules. (or something like that.. ill look again when im closer) i just need to figure out why it started working to begin with??

/dev/lirc no loger exits.. all the lines seem self explanitor except

*********************** SOLVED *********************

Wow good thing.. cause my computer was gonna grow wings and fly out a 2 story window.... (not that joking) i am going todo a complete howto in the howto section, so newbies dont have to go though what i just went though.. so coming soon. (but good side wow i learned alot) :D

On bootup this needed to run
Code:
setserial /dev/ttyS0 uart none

Code:
modprobe lirc_serial

Code:
/usr/local/sbin/lircmd

Code:
/usr/local/sbin/lircd



the last two where the ones i was missing.. little thing like starting the program.. lol .. Weird as many howtos i read never saw that i was suppose to run those.. finally google'ing it i found alittle howto...

Thanks for letting me vent here. :)
