JP1 Remotes

[gadget89]

Hi all,

I'm a newbie here, with a question that is jp1 related, but it's not about programming a jp1 remote.

I recently picked up a Blu-Ray player on eBay - it was a good deal, but came without a remote. I can play a movie without a

remote, but there is a firmware upgrade available that requires me to press the Enter key in order to install the upgrade.

Of course, assuming I can emulate that, I should be able to get the navigation keys working too.

I have built a serial IR transmitter for my computer, which works with WinLIRC. I know is working properly, because I found

a LIRC configuration for an RCA TV, and I was able to use WinLIRC to power an RCA TV on & off, adjust the volume up &

down, and switch channels up & down. I didn't test all the buttons.

My Blu-Ray player is Insignia NS-BRDVD3-CA. I have an RMDU file for the NS-BRDVD3. They are the same player - mine is the

Canadian version. They both use the same remote (BD003).

What I hope to do is use this info to come up with a WinLIRC configuration that will control the Blu-Ray player. If that

works, I could teach a learning remote. In the longer term, I hope to purchase a jp1 or jp1.x remote, and then my problem

will be solved.

Here's the RMDU file:

What I've learned to this point is that the Blu-Ray player uses the NEC1 protocol, the device number is 133 and the sub-device number is 237.

With this info, I was able to use makehex.exe with the NEC1 irp file to generate the raw hex codes for all the functions

from 0 to 255. Here is an example, function 17 (which is the Enter key).

Device Code: 133.237 Function: 17
0000 006D 0022 0002 0157 00AC 0015 0041 0015 0016 0015 0041 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0041 0015 0016 0015 0041 0015 0041 0015 0016 0015 0041 0015 0041 0015 0041 0015 0041 0015 0016 0015 0016 0015 0016 0015 0041 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0041 0015 0041 0015 0016 0015 0041 0015 0041 0015 0041 0015 0689 0157 0056 0015 0E94

I thought I would be able to use the raw hex codes in WinLIRC, but now I see that WinLIRC use decimal numbers when it uses raw data codes. I read somewhere that the LSB is transmitted first.

How do I convert each of the 4 digit hex codes into the appropriate raw data decimal format? And is this the proper approach?

The RCA file that I used with WinLIRC used hex values for each function. I am thinking that this method would be more desirable than the raw data method.

My objective is to generate a WinLIRC file for the NS-BRDVD3 remote - i.e. just 1 device, not many, as above.

Any advice would be appreciated.

Thanks in advance. And I apologize for such a lengthy question, but I wanted to give examples.

Just in case this turns out to be impossible, you may not realize that you can add these codes to a JP1 remote without using a cable. Check out THIS thread which lists compatible JP1 remotes and a way to manually program all the commands.

OK, I took a crack at it, let me know if it works ...

[gadget89]

Hi Robman - YES - It does work!!!!

Thanks so much. I'll give you a more detailed report in the morning - I have to play now, and I'll probably be up quite late. Thanks again.

I've been doing a lot of digging & reading since my first post in this thread, and along the way I stumbled across Vicky G's very excellent tutorial on infrared protocols, which is available here on this site. I would recommend this as a MUST READ for any newbies who are trying to do creative things with IR devices & remotes.

I was about to post this lirc file (which doesn't work) to get some pointers, but then I saw Robman's configuration, and I had to try it.

[vickyg2003]

I'm glad my explanation of the signals helped you.
I had been studying signals here for a long, long time without a clue as to what people were telling me.

I can explain the predata

The NEC1 signal looks like this.
IRP notation: {38.4k,564}<1,-1|1,-3>(16,-8,D:8,S:8,F:8,~F:8,1,-78,(16,-4,1,-173)*)

All Signals are assumed to be LSB unless stated otherwise.

You reported that the device was 133.

133=85hex=10000101binary
LSB(10000101)=1010 0001 = A1hex

Subdevice = 237
237 = EDhex=1110 1101binary
LSB(11101101)=1011 0111 = B7 Hex

I don't know how the rest of the LIRC is figured out.

Thanks for the feedback, Vicky. (Great tutorial, BTW!) So the device code & subdevice code are there in the pre_data, I just didn't recognize it. One mystery solved.

As it turns out, not all of the functions are working - in particular the navigation keys and the enter key are not working. I went through all 256 possibilities tonight trying to test them.

Power works, open/close works, and this is what I tested last night, but actually, as it turns out, there isn't very much else working.

Just when I think I am starting to get a handle on this, then reality sets in.

Hey Vicky, I read about the red button comcast remotes in some of your posts, but what about the gray button ones - they are still jp1.x? There are lots of them on eBay, just want to make sure before I buy something.

And if anyone can shed some illumination on my current WinLIRC dilemna - i.e a few keys working, many not working, it's much appreciated.

Thanks.

We have two upgrades for this device and they are both the same arrow key codes and they match the hex that Rob prepared.

Thanks for your help. This is a great forum - everyone is so helpful.

Well that file was my first attempt, and it didn't work, but I wasn't really expecting it to.

With all the info I've gotten back, I'm getting a much clearer picture.

But yes, I was using the Robman's file. I had to edit it a little, because WinLIRC was giving an error loading the file.

Things like "right arrow" it doesn't like, but "right_arrow" is OK.

So I'm using his file, just edited enough so that WinLIRC is not complaining. When I first tested it, I only tested a couple of codes, power and open/close. But I was having problems with the mouse on that computer I'm testing with, so that's as far as I went. I was pretty optimistic at that point anyways - it seemed like it was working.

[vickyg2003]

Given that information, I'd get rid of all the special characters (spaces, /, _, ...) from the button names. But I'd also start from 0 and work my way down to see if the file stops working at a specific line.

I just updated my earlier post to only use "_" as a special character, I removed the spaces and the "/"s

OK, here is a copy of my working LIRC config:

OK, here's an update.

I purchased a pair of Comcast 1067ABC3 remotes on eBay yesterday, so they should arrive later this week. I scoured the shops in my town for the RCA remote (RCRP05B) but couldn't locate one, so this seemed to be my best option.

I'm hoping they'll have the JP1 connector, or at least the holes, but even if they don't, that remote should work with the advanced codes that mdavej directed me to in his post.

I'm still experimenting with winlirc - I'm trying to send some raw codes, although at the moment I'm getting errors with the config file. I'll play around a little, and then post my results.

Once again, I'd like to thank all the wonderful folks on this forum who've been a great help in my experiments.

I expect I will probably have more questions in the future. I plan to build the JP1 interface cable so that I can have my way with these remotes.

Hopefully, as I learn more, I can repay the favor and help some future newbies out.
