Fun with LIRC
Apr 4, 2011 Computers, Linux, MythTV
I have successfully updated my bedroom MythTV frontend part way.
I did an upgrade using YUM and now running Fedora 14. I did not update MythTV yet since the server is running v.23 and have to update it first. All went well except having to fiddle with updating the NVIDIA driver by hand.
While I was tinkering, I set up LIRC to control the TV and Cable box as well as MythTV. The TV did not have a remote with it and it turns out Olivia’s codes are a bit weird. The remote that came with the Comcast STB worked, but not well. The universal remote I was using with Myth had the same issues but did not work with the STB. I wanted to have only one remote control everything, so what I did was set the universal remote to a code that nothing was using (RCA I think) and had LIRC send commands to the TV and STB using irexec and some irsend scripts. I use a home brew transmitter and old Packard Bell receiver.. I was having a lot of issues with errors that seemed to be coming from problems with the serial port. I ended up switching to the earlier mentioned test machine and that seemed to clear most of it up.
Now what I have is:
Remote
V
LIRC
V V V
MythTv – STB – TV
Ex. when I send Volume Up, LIRC receives it then sends the proper codes out to the TV.
A bit of a hassle, and a slight delay in each action, but the function is so much better with only one remote!
By the way, I was able to pull the hard drive and simply switch machines, even though one was Intel and one AMD. Ever try and do this with WinXP??????? (big pain!!)
