Lirc no output from irw or mode2 [SOLVED]

Hello.
I'm new to Arch which I've been trying to setup for my htpc which was running Mythubuntu 10.04 but, I've ran into a problem with lirc. I followed the arch wiki and googled and played with it for hours and I can't get it to work.
When I start it
/usr/sbin/lircd -n -d /dev/lirc0
lircd: lircd(default) ready, using /var/run/lirc/lircd
and try
irw
mode2 d- /dev/lirc0
cat /dev/lirc0
I press buttons and get nothing. From what I've googled so far everyone was able to get some kind of output with those. :(
What am I doing wrong? I just have an mce remote (MediaGate GP-IR02BK) nothing special. The red led on the receiver lights up when I press buttons and I made sure it still works by testing on a Windows 7 box.
Here is some more information:

With this module, the kernel will treat your remote as a keyboard by default, which causes lircd to fail to recognize remote input. An easy way to verify this is to run irw and see if it recognizes remote input.
but I didn't have output so I moved on.

No output from Lirc at all since the kernel update

I put this in a separate thread because I seem to have a different problem to the 'double press' issue and I'm pretty sure my remote isn't covered by mceusb. I've got a remote that until recently worked perfectly with the lirc_atiusb driver. However I get no output with irw or in boxee. I still get this in my dmesg output:

Hi,
i have the same problem with my X10 Remote.
I wrote the lirc developers: http://old.nabble.com/lirc_atiusb-and-2 … 53763.html
They recommend to use the ati_remote module. But for my remote control this modules doesn't work as i want.
The current lirc_atiusb module is just a pre version. So i think this is an upstream bug.
The current solution for me: i stay with 2.6.35 as long the bug is fixed.
I'd have to roll back my graphics drivers amongst other things, and the new kernel fixed an issue with my network card I'll try the ati_remote module when I get home.

Changing the seeded rdf report output from text to PDF

Hi All,
I am trying to change the seeded report "Print Requisition Report" output from text to PDF. I changed the output format in the concurrent program definition from text to pdf. The report is now getting displayed in pdf format, but the alignment of the fields are changed. The output is not printing as it was printing while in the text output format. The output looks very sloppy, with uneven fonts and too much of text wrapping.
I tried some formatting and fields are somehow getting displayed but doesnt look in proper format. I am not able to change the font style in the report builder 6i, even if i change it is printing in the same font style with uneven font size. I think reducing the font size might help, but i am unable to change.We are on 11.5.10.2. Please provide your valuable suggestions on how to go about.
Thanks
Sarvesh

Hi Hussein,
Thanks for the information. After the adjustments in the layout and the font change the report is now getting displayed without any clipping when clicked on view output. But when the same report is printed some characters on the left and and right side is getting clipped. Please help on how to solve this issue.
Thanks,
Sarvesh

Is any one else have issues with interactive PDF output from InDesign CC (2014)

I am currently trying to produce a document with a level of interactivity I have achieved many times before.
The interactivity is just a web style menu, show/hide the menu shows button set one, clicking on those shows a second set of buttons, and clicking in one of those goes to destination page and hides all menu buttons once more.
When output from ID CC 2014 the result is loads of missing buttons and no working menu.
Its not a corrupt ID file. I tried a brand new empty file, recreated basic structure with simple one state buttons and achieved similarly useless results.
If I back save using IDML and open in CS5, export from there, it works beautifully, so problem is not as many have been recently, to do with Acrobat browsers.
If I back save and open in InDesign CC (not 2014), export from there, it doesn't work, so problem is shared there!
Anybody any suggestions? Experienced similar and found a cure?
SOLVED BY A COLLEAGUE:
You can (no longer) use full stops/decimal points in button naming. Menu was hierarchically labelled as 1, (1.1, 1.2), (1.1.1, 1.1.2) etc.
Renamed 1_1, 1_1_2 etc and all functionality has returned. Why you could and now you can't, who knows!
Hope this helps you if you stumble across here with the same issue.

Thank you for reporting this.
I would consider this a bug in InDesign CC v9.x and v10.x and would report it:

(Cannot test it right now.)

Multiple Input and Output from a 6534

Hello
I am after some advice regarding my PCI 6543 digital I/O card and the best way to achieve my desired results. I am programming in Visual C++ with Ni-DAQ 7.
I want to generate a pattern output from one of the ports, Port A, following a software command. This pattern consists of a 10uS pulse on DIOA0, that repeats 200 times with a period of 100uS. I want this DIOA0 output line to initiate an input on ports C and D, possibly through the REQ pin. Consequently the input should acquire 200 times for each call to the pattern output.
I want this to repeat, so the pattern output goes again (as in a FOR loop), and the input occurs again for an as yet undetermined number of times.
I have managed to get something worki
ng for 1 iteration, and I can generate multiple pattern outputs, but the inputs only seem to acquire for the 1st iteration. However, if I step through the code in debug mode I can get the input to work correctly.
Any ideas would be gratefully appreciated.
I am still trying to get some earlier problems with this application solved.
Kind Regards
Jamie

Hi Jamie,
There are a couple different ways you can loop from a buffer. You can either use the onboard memory of the 6534 and loop from there or you can specify as a software configuration that the board loop through the PC memory buffer.
For the onboard looping you need to specify the following:
iStatus = Set_DAQ_Device_Info (1, ND_PATTERN_GENERATION_LOOP_ENABLE, ND_ON);
For software, PC memory looping, the following function specifies this:
iStatus = DIG_DB_Config (iDevice, iGroup, 1, 0, 1);
I attached a couple programs that might be of use. Check this post:

In selection screen option if I write any table name then how can i select this table in select query of ABAP program ?.
I may select any tables in select options of screen. But In select query I should get that table name automatically.. How ?
e.g. If i put table name as an input i.e. MARA in select option .
In program how to write select query to get records from that table ?
SELECT MTART MATKL from MARA
Every time I should not go to select query of program & replace the tablename.

Output from JDBC Adapter mapped to multiple message types

Hi!
I face to a problem with the message mapping.. I do select with the JDBC adapter. This statement selects one field of clob type and it already contains a message - XML document. Depending of the type of this message will be done the message mapping and also the target message type depends on this XML document type. But when u define message mapping, there must be always a target message type... But in the design time, I don't know the exact type! It is dynamic...
And not just with the message, the same situation is also with the target interface...
Any ideas how to solve this?
Thanx, Peter

Hi,
I saw the weblog, but I think more important is the 'XI in action' mentioned in this one..
/people/ravikumar.allampallam/blog/2005/06/22/sap-xi-in-action
What I just can not understand from that blog is the step 2/4:
Receive XML file of any format and route to interface specific BPM..
How is it possible? On the output from the 1st BPM must be exact interface defined... How can different messages go out and than into the 2nd BPM?
Can you please write me, how the individual steps could follow after each other to achieve this?

Multi page recordset output from ASP page on Spry Tabbed Panel Widget

I am using a simple Spry Tabbed panel set on my asp page to show the output from different ASP pages, inside the tabbed panels. The tabbed panels on the page under consideration (destination page) display the output from different asp pages (source pages). The source asp pages generate multi page outputs which are paginated on the source page itself and pagination links are displayed on the source page itself.
However, we dont want to display the source page outside of the tabbed panel, but instead the output content from the source asp pages should show inside the tabbeed panels only. The first page generated by the source asp page displays correctly inside the tabbed panel. However, when the user clicks on the links for the next page generated by the source asp page, but which is being displayed inside the destination page tabbed panel, they dont display the next page inside the tabbed panel. Instead the source asp page displays the output outside the tabbed panel destination page.
Please advise on how to ensure that the user can page through the recordset generated by the source asp page by clicking on the pagination links at the bottom of the records, while ensuring that the output displays within the tabbed panels on the destination asp page.
I am enclosing the source code being used to generate the spry tabbed panel widget and also updating it with the output from the source asp page. In this case, the code given below is from the main page containing the widget and the source asp page is "sample.asp", which generates multi page output.
Please note that I am not too keen on using xml data sets output from the source asp page, but would be more comfortable with directly using the asp pages to fill the tabbed panel content.
Please help

I fully agree that the problem does not lie with tthe tabbed panels.
The solution would probably be first required to be tried using ajax on any div tab.
Then the same code would have to be used on Sprytabbed panel. Hence, the following may be advised:
1. Sample code for server side pagination and displaying inside any div tag and refreshing it using ajax. the update link would also lie inside the div tag which would show the next/ previous page without reloading the page.
2. Then adapting the refresh technique using ajax in the Spry Tabbed panel using the inbuilt updatecontent method of the Spry Tabbed panels.
In order to achieve the above, I am getting the recordset output in the tab content as expected. The recordset is also getting the pagination links from server side asp as required.
However, it is also generating the following error.
Webpage error details

What is the best way to run two programs simulataneously using the output from one to run the other?

I just kind of wanted to get an opinion from some people on here. I have two main VIs. The first is a DAQ system that reads 99 different sensors and feeds that data into an array. The second is a real-time processing system that is designed to take the array and do numerous calculations. Both VIs output data to the front panel that I want to see, so I don't want to just use one as a SubVI.
Is there a simple way to run both VIs, using the output from the DAQ system to feed the processor so that you can easily see the front panels of both VIs? I had considered just copying the real-time processor code into the DAQ VI, but I'm worried the resultant VI will be very large and unsightly.
On a side note, am I over thinking this? Excuse me if this is a rather dumb question, it's been a long week...aaaand it's Wednesday.
Solved!
Go to Solution.

There are a number of ways that you can go about this, but having both front panels open isn't a problem (assuming there is screen space!). Both could be sub-vi's of another "calling" vi, with their front panels set to open when called. The data from the DAQ side can be sent to the other through a number of ways, "producer-consumer" (many threads about this topic, examples in the LabVIEW examples, etc.) is one of the more robust techniques. If created correctly it allows one to run at a different rate than the other, although if the producer is "producing" much faster than the consumer can "consume" it will end up with problems.
I guess I type too slowly

Calling Captivate HTML5 Output from an application

I want to call Adobe HTML5 and Flash Captivate published output from an application. There are several issues I'm currently experiencing duing this:
1) Iframe.
Using an Iframe works for the most part, except that we are hosting many Captivate presentations and there's a bloated number of files when showing the presentation this way, since each one gets the full set of support files needed.
There's also a bug when hiding and reshowing the Captivate presentation (using jQuery.hide and jQuery.show respectively on the parent form): when reshowing the video player controls disappear.
To get around this I progammatically set the height of the iframe to zero, and then set it back to desired screen height when showing the presentation.
2) view in app.
I'm guessing this could work but there's such a mishmash of published files and resources, in our case over 200 in all.
There are several issues we run into in general:
1) jQuery in the published captivate is an old version of jQuery 2.0.0 is current.
2. jQuery ui in the published captivate is an old version of jQuery. 1.10.2 is current.
3. [presentation_name].htm files do not capture javaScript events or open urls currently in the proesentation, only the index.html file does.

Yesterday suddenly the sound output from my Headphone is not working

Hi, I've Mac Book Pro 15" with Retina display. Yesterday suddenly the sound output from my Headphone is not working. When I tried to solve this, I've noticed in system preferences it's jumping from Internal speakers to Head phone and vice versa. Can anyone help me on this issue please? I am using the original Apple Headset only.
Thanks

Tell us:
OS X version ?
What may have changed prior to the onset of the issue of "... suddenly... not working..." and " ... preferences ... jumping from ..." ? Software added, upgraded, updated?
what precidely do you mean by " ... preferences ... jumping from ..." ?

I see that your Question has languished for some period of time without response. You have posted your issue in Using Apple Support Communities whose topic is 'How to use this forum software's interface, features and/or how to find what you wish'. It is a relatively low traffic and inappropriate forum for your problem. I will ask our Hosts to move it to " MacBook Pro " where it may get a more rapid response from your fellow users.

Get complete output from java.lang.Process

How do I get the complete output from java.lang.Process?
By the time I've started reading from Process.getInputStream() the process has already terminated...

I solved the problem:
private int exec(String pArguments[], OutputStream pOut, OutputStream pErr) throws IOException {
     class ProcessOutputPrinter implements Runnable {
          private InputStream ivIn;
          private OutputStream ivOut;
          public ProcessOutputPrinter(InputStream pIn, OutputStream pOut) {
               ivIn = pIn;
               ivOut = pOut;
          public void run() {
               try {
                    for(int tByte; (tByte = ivIn.read()) != -1; ) {
                         ivOut.write(tByte);
                    ivOut.flush();
               catch(IOException e) {
                    e.printStackTrace();
     // Start process
     Process tProcess = Runtime.getRuntime().exec(pArguments);
     // Create out printer
     Thread tOutPrinter = new Thread(new ProcessOutputPrinter(tProcess.getInputStream(), pOut), "NamingAdmin out-printer");
     tOutPrinter.start();
     // Create err printer
     Thread tErrPrinter = new Thread(new ProcessOutputPrinter(tProcess.getErrorStream(), pErr), "NamingAdmin err-printer");
     tErrPrinter.start();
     // Wait for process and printers to finish
     try {
          tProcess.waitFor();
          tOutPrinter.join();
          tErrPrinter.join();
     catch(InterruptedException e) {
     // return process exit value
     return tProcess.exitValue();

I'm working on DC Motor control using DAQ. There is sufficient voltage output from DAQ but not current. What should i do so as to drive the motor

I'm working on DC Motor control using DAQ. There is sufficient voltage output from DAQ but not current. What should i do so as to drive the motor. Could you suggest me appropriate driver IC using which this problem can be solved.
Saravanan.T

You really should use a DC motor controller to control a DC motor, look at the 754410 IC for a good example. You should be able to interface these to most DAQ devices.

Reading output from a Solaris(UNIX) shell script

Hello All, I have written some fairly large shell scripts. I have also written a simple java GUI that contains a button that will run the script. The script runs. The problem is that I cannot see the output from the script in the x-term that I used to run my java class file.
I am developing in a windows environment, I have a silly little system.out that prints "Button Pressed", which works in windows just fine but on my ultra 10 running Solaris 8 the term just sits there no output to the srceen.
Has anyone out there solved this problem or know of a way that I can? Thanks

I don't know how to print out to the x-term. But you can add a JTextArea to the GUI and get the output there.
String output = null;
StringBuffer returnString = new StringBuffer();
String command = /path/to/shell/script/script.sh
process = Runtime.getRuntime().exec(command);
InputStreamReader isr = new InputStreamReader (process.getInputStream());
input = new BufferedReader(isr);
while((output = input.readLine()) != null){
returnString.append(output);
}Wouldn't a System.out.println(returnString.toString()) print to the x-term console?
hope this helps.

Lirc no output from irw or mode2 [SOLVED]
