JP1 Remotes

[RamBuck]

It's been many years since this post, which suggested a solution... However, I'm trying to use RMIR (2.00 preview 7) with Tommy's USB Flash JP1.2/3 on OSX 10.5.8. So far, no signs of life from the USB device except when I plug it in. I've installed the latest driver, and the device shows up in my USB device list.

I tried using on Parallels Desktop, running Windows XP. At least I can download the raw data. So I believe the device is functional.

Someone suggested a USB selction in the "Interface" Menu... I see no such menu. Are there port settings available in RMIR? What other properties can be defined in remotemaster.properties file?

When you say you installed the latest driver, what does that mean?

My guess is you installed FTDI device driver, but not the OS/X JP1 libraries. You can get those here. They aren't included with RMIR yet.

I'm willing to be your guinea pig. But I'm new to this forum. Been reading it for a while and finally took the plunge (after comcast dropped support for my home theater... and the kids smashed the remote... and then smashed my Harmony ). The driver I've installed is indeed the FTDI driver for OSX. Are the libraries necessary? It's my understanding these would be for compiling source code...

As for my problems with using RMIR... I quoted the message from 2003, which said something like RMIR worked like a charm. It's taken me about a week of reading to come to the realization that RM, IR, and RMIR are sometimes mistakenly referred to the same thing "Remote Master". The html help file in particular.

Thanks for the help. I will try it out and let you know. It's my understanding that the comcast remote(s) have their own confusing set of problems. )

Ok, I followed the instructions in the readme, but still have some problems.

1) don't forget the .jar extension when invoking remotemaster.jar
2) Did you assume you're running as root? I had to use sudo...
3) I have a class conflict. I'm running on Core 2 duo, and have the x86_64 libraries. So, am I running the wrong java version? Here's the error:


Boson:remotemaster administrator$ sudo java -jar ./RemoteMaster.jar -ir

Ok. No problem with versions. I cranked permissions, sudo chmod 775 * in the remotemaster directory and then it was able to run without errors.

I still don't see an interface selection in the remote menu.

[RamBuck]

Back to sleuthing...

[gfb107]

The only thing I can think of is to chmod 755 the library files too.

As far as we know, you are only the second person to try this. alex750 was the other, and he is the one who compiled the source for OS/X, wrote the instructions, and posted the zip file with the binaries.

We know that he had more success than you are having, because he was able to load the libraries, and DecodeIR produced at least some correct results. We do not know if he was able to successfully up/download from a JP1.2/3 remote, because the last we heard he didn't have a cable.

I did a little googling, and it looks like your problem may be that you are running code built on OS/X 10.6 on OS/X 10.5.8

See http://stackoverflow.com/questions/1440456/static-libraries-in-version-cross-compiled-program

You may have to rebuild the binaries yourself, or maybe we can get alex750 to rebuild them in a way that is compatible with 10.5.8 (if that is even possible).

Thanks.

I've done similar sleuthing in porting other unices usually the main difficulty is figuring out where OSX stores the frameworks. Hopefully none of the dependencies rely on having 10.6, or I could spend a lot time recompiling, or I could just upgrade... But shouldn't have to. Xcode should be able to compile universal binaries, but sometimes they make huge changes between updates. The major change with 10.6 was to drop all vestiges of PPC support. 10.6 only works on intel processors. The fact that Alex compiled for PPC suggests 10.5 at least. If I can start with his source code, I can probably just recompile without any problems. I will try a bit tonight.

Am I really the first to try using the USB flash JP1.2/3 cable in OSX?

Hi Robman,

[MikeT]

In the meanwhile I built my cable but it only works partly. First, RM was always crashing. After some debugging, I noticed that the buffer for the port name in jp12serial.cpp/openPort() was too short, so I changed it:
