  • C# SerialPort - Problems mixing ports with different baud rates.

    - by GrandAdmiral
    Greetings, I have two devices that I would like to connect over a serial interface, but they have incompatible connections. To get around this problem, I connected them both to my PC and I'm working on a C# program that will route traffic on COM port X to COM port Y and vice versa. The program connects to two COM ports. In the data received event handler, I read in incoming data and write it to the other COM port. To do this, I have the following code: private void HandleDataReceived(SerialPort inPort, SerialPort outPort) { byte[] data = new byte[1]; while (inPort.BytesToRead > 0) { // Read the data data[0] = (byte)inPort.ReadByte(); // Write the data if (outPort.IsOpen) { outPort.Write(data, 0, 1); } } } That code worked fine as long as the outgoing COM port operated at a higher baud rate than the incoming COM port. If the incoming COM port was faster than the outgoing COM port, I started missing data. I had to correct the code like this: private void HandleDataReceived(SerialPort inPort, SerialPort outPort) { byte[] data = new byte[1]; while (inPort.BytesToRead > 0) { // Read the data data[0] = (byte)inPort.ReadByte(); // Write the data if (outPort.IsOpen) { outPort.Write(data, 0, 1); while (outPort.BytesToWrite > 0); //<-- Change to fix problem } } } I don't understand why I need that fix. I'm new to C# (this is my first program), so I'm wondering if there is something I am missing. The SerialPort defaults to a 2048 byte write buffer and my commands are less than ten bytes. The write buffer should have the ability to buffer the data until it can be written to a slower COM port. In summary, I'm receiving data on COM X and writing the data to COM Y. COM X is connected at a faster baud rate than COM Y. Why doesn't the buffering in the write buffer handle this difference? Why does it seem that I need to wait for the write buffer to drain to avoid losing data? Thanks!

  • Having a little trouble with this Java code. Beginner probably mixing some things with C#.

    - by Sergio Tapia
    package practico1; /** * Programador: Sergio Tapia Gutierrez * Fecha: Lunes 10, Mayo - 2010 * Practico: 1 */ public class Main { public static void main(String[] args) { System.out.println("Esta es una pequena aplicacion para mostrar los"); System.out.println("distintos tipos de datos que existen en Java 6."); //boolean, char, byte, short, int, long, float, double, String ejemplosBoolean(); } public void ejemplosBoolean(){ } } So, I'm just testing some things out, but I'm getting an error claiming that I'm trying to run ejemplosBoolean() in a static context when it isn't a static method. My question is, in Java do methods have to have static in order to use them even if they are in the same class?

  • mixing OpenGL and Interface Builder/ UI Controls - bad idea? Why? (iPhone)

    - by Adam
    I've heard that OpenGL ES and standard iPhone UI controls don't play well together, but I'm wondering if anyone knows why, and what the effects are? I'm writing an OpenGL based game, and the view is loaded from a nib file with ui controls, and it seems to work ok, but the game is really simple at this point... does using ui controls cause some kind of performance hit?

  • Mixing libraries with and without RTTI with GCC on Mac OS X?

    - by Steve the Plant
    I've been banging my head on an issue and before I continue injuring myself some more, I'd like to confirm: Is it possible to have a GCC project that uses libraries that are compiled with and without RTTI? So, for example, I have project A (compiled without RTTI) that uses library B (compiled with RTTI) and library C (compiled without RTTI). In theory, is all that supposed to compile and link with no problems?

  • pitfalls with mixing storage engines in mysql with django?

    - by Dave Orr
    I'm running a django system over mysql in amazon's cloud, and the database default is innodb. But now I want to put a fulltext index on a couple of tables for searching, which evidently requires myisam. The obvious solution is to just tell mysql to ALTER TABLE to myisam, but are there going to be any issues with that? One that comes to mind is that I'll have to remember to do that any time I build a new version of the database, which should theoretically be rare, but there doesn't seem to be a way to tell django to please set the storage engine at the table level. I guess I could write a migration (we use south). Any other things I might be missing? What could possibly go wrong?

  • Doctrine: Mixing YAML markup and db manager (navicat) editing?

    - by ropstah
    I think the answer to this question should be: No. However I hope to be corrected. I'd like to edit our database using a mixture of YAML markup + Doctrine createTables() and Navicat editing. Can I maintain the inheritance which is marked up? Example (4 steps, at step 4, Doctrine is in no way able to re-create the inheritance schema... or is it?): Step 1: Create YAML with inheritance --- Entity: columns: username: string(20) password: string(16) created_at: timestamp updated_at: timestamp User: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 1 Group: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 2 Step 2: Create tables using Doctrine (and drop/create db if nessecary) Created sql: CREATE TABLE entity (id BIGINT AUTO_INCREMENT, username VARCHAR(20), password VARCHAR(16), created_at DATETIME, updated_at DATETIME, type VARCHAR(255), PRIMARY KEY(id)) ENGINE = INNODB Step 3: Edit table using Navicat Step 4: Refresh YAML file because of 'external' edits...

  • Lubuntu upgrade to 13.04 killed sound with ALSA. How to troubleshoot?

    - by Sven
    After upgrading to 13.04 from 12.10 Lubuntu lost audio playback after unplugging usb soundcard (Polycom) and plugging it back in. Volume control was gray and leading to pulseaudio mixer (not installed) so I uninstalled the pulseaudio package. I also removed and reinstalled the alsa-base package. After restart I have the alsamixer back everything seemingly as usual(volume 100%, unmute) but every sound program gets me errors no matter what device I select. aplay -L: null Discard all samples (playback) or generate zero samples (capture) pulse PulseAudio Sound Server default:CARD=NVidia HDA NVidia, ALC662 rev1 Analog Default Audio Device sysdefault:CARD=NVidia HDA NVidia, ALC662 rev1 Analog Default Audio Device front:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Front speakers surround40:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Digital IEC958 (S/PDIF) Digital Audio Output hdmi:CARD=NVidia,DEV=0 HDA NVidia, HDMI 0 HDMI Audio Output dmix:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Direct sample mixing device dmix:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Direct sample mixing device dmix:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Direct sample mixing device dsnoop:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Direct sample snooping device dsnoop:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Direct sample snooping device dsnoop:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Direct sample snooping device hw:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Direct hardware device without any conversions hw:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Direct hardware device without any conversions hw:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Direct hardware device without any conversions plughw:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Hardware device with all software conversions plughw:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Hardware device with all software conversions plughw:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Hardware device with all software conversions default:CARD=Communicator Default Audio Device sysdefault:CARD=Communicator Default Audio Device front:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Front speakers surround40:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 4.0 Surround output to Front and Rear speakers surround41:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio IEC958 (S/PDIF) Digital Audio Output dmix:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Direct sample mixing device dsnoop:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Direct sample snooping device hw:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Direct hardware device without any conversions plughw:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Hardware device with all software conversions etc/asound.conf: defaults.ctl.card 1 defaults.pcm.card 1 defaults.pcm.device 1 Following gets same result with both devices. aplay -vv -D front:CARD=NVidia,DEV=0 "Release the Pressure.wav": Playing WAVE 'Release the Pressure.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: set_params:1087: Channels count non available Guayadeque mp3 playback: AL lib: alsa_open_playback: Could not open playback device 'default': No such file or directory 21:32:14: Error: Gstreamer error 'Configured audiosink playbackbin is not working.'

  • Dell XPS 15 (L502x) sound problem

    - by lauramolenaar
    I have a problem with my sound on my Dell XPS 15.

  • Advice when using COM Object/CComPtr and the STL

    - by YoungPony
    Hello, I am doing some COM related things with directshow such as: typedef CComPtr<IBaseFilter> AutoIBaseFilterPtr; map<CString, AutoIBaseFilterPtr> _filterMap; To store a list of directShow related com objects and their friendly name. After finding this article (See:Problem 2) on how changes in VC10 compiler might effect previously OK code, I am wondering if there are any more things to watch out for when mixing the STL and CComPtr or prehaps just mixing the STL and COM in general. Any tips would be greatly appreciated, thanks

  • extracting a quadrilateral image to a rectangle

    - by Will
    In the image below, the sign on the side of the van is not face-on to the camera. I want to calculate, as best I can with the pixels I have, what it'd look like face on. I imagine that this is some kind of loop through the x and y axis doing a Bresenham's line on both dimensions at once with some kind of mixing when pixels in the source image overlap - some sub-pixel mixing of some sort? What approaches are there, and how do you mix the pixels? Is there a standard approach for this?

  • Ruby (on Rails) && PHP - two great things that work great together???

    - by pedalpete
    I've done very little work with Ruby, and have an app I've written in PHP. I would like to add some functionality which is available in open sourced Ruby code. I could either try to translate the Ruby to PHP, or try mixing the two. Though I think the mixing part would be somewhat silly. I believe my options are to either mix ruby with php, or translate the ruby code into php. Anybody have any suggestions on this, or other ideas? I am not really interested in converting my entire app into Ruby just so I can get this feature (I saw Derek Sivers post about that which convinced me. http://www.oreillynet.com/ruby/blog/2007/09/7%5Freasons%5Fi%5Fswitched%5Fback%5Fto%5Fp%5F1.html)

  • Tagging gone from Nautilus, GAJ, tracker

    - by nathan28
    I had installed Gnome Activity Journal, Zeitgeist and Tracker but borked the install by mixing the PPAs with the universe repos. I removed all the packages, did apt-get remove --purge, then did a locate to manually rm everything else. Then I reinstalled from the PPAs properly. Now I can't tag files anymore, either in Nautilus or GAJ. What packages are involved in tagging? What else might I be missing?

  • How to serve Rails application with Passenger/Apache without domain name?

    - by grifaton
    I am trying to serve a Rails application using Passenger and Apache on a Ubuntu server. The Passenger installation instructions say I should add the following to my Apache configuration file - I assume this is /etc/apache2/httpd.conf. <VirtualHost *:80> ServerName www.yourhost.com DocumentRoot /somewhere/public # <-- be sure to point to 'public'! <Directory /somewhere/public> AllowOverride all # <-- relax Apache security settings Options -MultiViews # <-- MultiViews must be turned off </Directory> </VirtualHost> However, I do not yet have a domain pointing at my server, so I'm not sure what I should put for the ServerName parameter. I have tried the IP address, but when I do that, restarting Apache gives apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName [Sun Jan 17 12:49:26 2010] [error] VirtualHost *:80 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName [Sun Jan 17 12:49:36 2010] [error] VirtualHost *:80 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results and pointing the browser at the IP address gives a 500 Internal Server Error. The closest I have got to something sensible is with <VirtualHost efate:80> ServerName efate DocumentRoot /root/jpf/public <Directory /root/jpf/public> AllowOverride all Options -MultiViews </Directory> </VirtualHost> where "efate" is my server's host name. But now pointing my browser at the server's IP address just gives a page saying "It works!" - presumably this is a default page, but I'm not sure where this is being served from. I might be wrong in thinking that the reason I have been unable to get this to work is related to not having a domain name. This is the first time I have used Apache directly - any help would be most gratefully received!

I think that I can fix this if I run other (lighter) window-manager than KDE4. But that is not a solution occasional linux user. Do I have any chance to get StepMania under KDE4 completely working?

  • How should I secure my webapp written using Wicket, Spring, and JPA?

    - by Martin
    So, I have an web-based application that is using the Wicket 1.4 framework, and it uses Spring beans, the Java Persistence API (JPA), and the OpenSessionInView pattern. I'm hoping to find a security model that is declarative, but doesn't require gobs of XML configuration -- I'd prefer annotations. Here are the options so far: Spring Security (guide) - looks complete, but every guide I find that combines it with Wicket still calls it Acegi Security, which makes me think it must be old. Wicket-Auth-Roles (guide 1 and guide 2) - Most guides recommend mixing this with Spring Security, and I love the declarative style of @Authorize("ROLE1","ROLE2",etc). I'm concerned about having to extend AuthenticatedWebApplication, since I'm already extending org.apache.wicket.protocol.http.WebApplication, and Spring is already proxying that behind org.apache.wicket.spring.SpringWebApplicationFactory. SWARM / WASP (guide) - This looks the newest (though the main contributor passed away years ago), but I hate all of the JAAS-styled text files that declare permissions for principals. I also don't like the idea of making an Action class for every single thing a user might want to do. Secure models also aren't immediately obvious to me. Plus, there isn't an Authn example. Additionally, it looks like lots of folks recommend mixing the first and second options. I can't tell what the best practice is at all, though.
