I will try and offer any help I can. </p> http://forum.slashdev.ca/topic/42#post-103 Sun, 13 Nov 2011 18:10:15 +0000 madmalkav 103@http://forum.slashdev.ca/ <p>Thanks for the tip. I have a free week near and will try what you recommended . </p> http://forum.slashdev.ca/topic/42#post-102 Sun, 13 Nov 2011 16:52:08 +0000 jiggak 102@http://forum.slashdev.ca/ <p>I'm afraid I don't have any direct experience in this area.</p> <p>For starters you will need to set the MCU type in the <a href="http://git.slashdev.ca/ps3-teensy-hid/tree/src/Makefile">Makefile</a> (line 58) to <strong>at90usb82</strong> for the UNO's USB chip. You will also need an AVR programmer to flash via ICSP interface.</p> <p>In my <a href="http://git.slashdev.ca/ps3-teensy-hid/tree/src/gamepad.c">gamepad.c</a> file you will need modify all the <em>if</em> statements. They currently sample the digital inputs on the teensy board and set values in the USB report accordingly.</p> <p>I believe the UNO uses a serial interface between the Atmega8U2 and the ATmega328. So all of the <em>if</em> statements would be replaced with code that samples the Atmega8U2 serial port.</p> <p>My recommendation would be to make a sketch that reads digital pins on the Arduino and writes out a series of bytes to the serial port that matches the <em>gamepad_state_t</em> struct (see <a href="http://git.slashdev.ca/ps3-teensy-hid/tree/src/usb_gamepad.h">gamepad.h</a> line 9). The digital pins you choose is up to you just don't use pin zero or one since those are used by the serial port. Write and test the sketch by watching the serial monitor in the Arduino software on your PC.</p> <p>Then in your gamepad.c file you need to read from the Atmega8U2 serial port. I'm not sure what the exact code would look like, but here is some pseudo code:</p> <pre><code>// read from serial port directly to USB report buffer read_serial((uint8_t*)gamepad_state, sizeof(gamepad_state_t));</code></pre> http://forum.slashdev.ca/topic/42#post-101 Sun, 13 Nov 2011 13:52:19 +0000 madmalkav 101@http://forum.slashdev.ca/ <p>I have been looking for documentation about adapting teensy projects to run on arduino but haven't find anything. What considerations must I take in order to adapt the code, and also to make the proper physical equivalent connections on my Arduino? </p> http://forum.slashdev.ca/topic/8#post-27 Tue, 21 Dec 2010 13:08:28 +0000 benvd 27@http://forum.slashdev.ca/ <p>Oops, kind of lost track of this for a while.</p> <p>Apparently you can add commands to ~/.jdbrc which will be automatically executed when starting jdb. So I just did <code>echo "resume" &gt;&gt; ~/.jdbrc</code> and this minor annoyance was gone.</p> <p>OK, so my assumptions were wrong and barry just doesn't support step-by-step debugging. Ah well, I never got that to work reliable in Windows (with official tools) either, so just having stdout is not that bad. :) </p> http://forum.slashdev.ca/topic/8#post-26 Mon, 06 Dec 2010 20:51:11 +0000 jiggak 26@http://forum.slashdev.ca/ <p>Unfortunately I haven't used bjdwp at all. You might try emailing the <a href="http://sourceforge.net/mail/?group_id=153722">Barry list</a>. The folks there are very receptive and helpful.</p> <p>Nicolas is the guy who created bjdwp and as far as I know it's unfinished. Breakpoints won't work neither will inspecting object references. I think about the only thing this would be useful for is seeing the standard output (ie: System.out.println() output).</p> <p>I wouldn't be surprised if adding this feature to auto-resume would be a simple thing to add so if you ask nicely Nicolas might be able to knock it out pretty quick. Or you can dig into the barry code. </p> http://forum.slashdev.ca/topic/8#post-25 Mon, 06 Dec 2010 11:20:48 +0000 benvd 25@http://forum.slashdev.ca/ <p>Hi. This is not directly related to your blogposts (since you use virtualised jdwp, and not bjdwp (i.e. the Barry implementation of jdwp)), but I figured I'd ask it here anyway, since you seem to know a lot about BlackBerry development on non-Windows OSes.</p> <p>After I run my app on a (physical) device, I start "bjdwp localhost 8000". After that, I can connect to this using "jdb -connect com.sun.jdi.SocketAttach:hostname=localhost,port=8000". After connecting, though, nothing seems to happen until I enter the resume command in jdb. Then it's smooth sailing.</p> <p>I'd love to be able to debug using eclipse since it's a much more comfortable environment. I created a new debug configuration for this, as follows: a Remote Java Application with connection type = "Socket Attach", host = "localhost" and port = "8000". In other words, the same kind of connection as the jdb command. This doesn't work, however -- it keeps trying to connect.</p> <p>Now, I assume this is because I need to do a resume, like I needed to do with jdb, but I can't do that from within eclipse (the resume button is greyed out).</p> <p>Any suggestions? </p> http://forum.slashdev.ca/topic/7#post-24 Thu, 25 Nov 2010 03:15:37 +0000 amsiddh 24@http://forum.slashdev.ca/ <p>Hi Jiggak,</p> <p>Thanks for your reply,</p> <p>I will try this things and get back if i stuck anywhere.</p> <p>Thanks,<br /> siddh </p> http://forum.slashdev.ca/topic/7#post-23 Wed, 24 Nov 2010 16:01:04 +0000 jiggak 23@http://forum.slashdev.ca/ <blockquote><p>During OTA intallation or App World do i need both project and library cod files or Only project cod file will do.</p> </blockquote> <p>I don't know how App World works. But for regular OTA you need your .cod file (or multiple files) and a .jad file with references to the .cod files. BB-ant-tools comes with an ant task to help generate an OTA ready .jad file. It's called <a href="http://bb-ant-tools.sourceforge.net/docs#jadtool">jadtool</a>.</p> <blockquote><p>One more thing i would like to know using ant tool can i have only one cod file for my application.<br /> (my application - which is having a dependency on other jar) Where as your Helloworld dependency example is generating the two cod files.</p> </blockquote> <p>I think you can tell rapc to compile from .java source files AND a .jar file containing already compiled .class files. Try searching <a href="http://supportforums.blackberry.com/">the official forums</a> for details on compiling a .cod from .jar file. </p> http://forum.slashdev.ca/topic/7#post-22 Wed, 24 Nov 2010 07:07:42 +0000 amsiddh 22@http://forum.slashdev.ca/ <p>Hi Jiggak,</p> <p>One more thing i would like to know using ant tool can i have only one cod file for my application.<br /> (my application - which is having a dependency on other jar) Where as your Helloworld dependency example is generating the two cod files. </p> http://forum.slashdev.ca/topic/7#post-21 Wed, 24 Nov 2010 04:34:46 +0000 amsiddh 21@http://forum.slashdev.ca/ <p>Hi Jiggak,</p> <p>Thanks for your reply, </p> <p>The problem got solved with your suggestion.

See <a href="http://www.slashdev.ca/2008/04/03/mds-simulator-in-linux/">this</a> post for how to make a script to launch it.</p> <p>This is only necessary for apps on the blackberry that attempt to use BES or BIS for network connections. Direct TCP or Wifi should work without the MDS simulator.</p> <p>And I'm afraid I have no knowledge of phonegap. </p> http://forum.slashdev.ca/topic/4#post-11 Fri, 07 May 2010 07:49:44 +0000 pamepros 11@http://forum.slashdev.ca/ <p>Josh, do you know how to configure the simulator to have internet on the phone?<br /> Can I add something to the sh script? (some extra variable to configure it)<br /> Also, do you have any knowledge of phonegap for blackberry?<br /> Thanks<br /> Pam </p> http://forum.slashdev.ca/topic/4#post-10 Thu, 06 May 2010 14:24:41 +0000 jiggak 10@http://forum.slashdev.ca/ <p>I personally have not been able to get the simulator to work 100% of the time. It is very unstable using wine emulation. You might also want to try <a href="http://www.azizuysal.com/2009/07/blackberry-development-on-mac-os-x.html">this post</a>. The author uses the <strong>winetricks</strong> script to install a few extra components into wine.</p> <p>For me, by far the most reliable method for using the simulator is with a Windows VM using VirtualBox (outlined <a href="http://www.slashdev.ca/2008/04/03/blackberry-development-using-linux/2/">here</a>).</p> <p>As for the Spanish translation, a link back to my blog would be great. Thanks!</p> <p>If you have tips on getting anything else working, feel free to use this forum. I'm sure others would appreciate your findings. </p> http://forum.slashdev.ca/topic/4#post-9 Thu, 06 May 2010 11:29:17 +0000 pamepros 9@http://forum.slashdev.ca/ <p>Josh,<br /> I have almost everything working now. I have some things still missing..<br /> The simulator worked fine the first 2 times, now it's not working any more, here's the last lines the terminal shows:</p> <p>err:ole:CoCreateInstance apartment not initialised<br /> err:seh:setup_exception_record stack overflow 988 bytes in thread 0009 eip 00a352eb esp 00230f54 stack 0x230000-0x231000-0x330000<br /> err:ntdll:RtlpWaitForCriticalSection section 0x110048 "heap.c: main process heap section" wait timed out in thread 003d, blocked by 0009, retrying (60 sec)<br /> err:ntdll:RtlpWaitForCriticalSection section 0x110048 "heap.c: main process heap section" wait timed out in thread 003d, blocked by 0009, retrying (60 sec)<br /> err:ntdll:RtlpWaitForCriticalSection section 0x110048 "heap.c: main process heap section" wait timed out in thread 003d, blocked by 0009, retrying (60 sec)</p> <p>Also, I couldn't integrate de simulator to eclipse. But as long as I can package the app and then try it in the simulator separately I have no problem (or that's what I thought).<br /> Anyway, I updated and translated to spanish your tutorials, if I ever publish them I'll reference the source (if that's ok with you) if you want a copy or if you want a hand I can write them in english for you with the latest versions of everything (once I get it to work of course haha)</p> <p>That's all for now, I'll login later to see if you could help me with this.<br /> Thanks</p> <p>pam </p> http://forum.slashdev.ca/topic/4#post-8 Thu, 06 May 2010 09:16:53 +0000 jiggak 8@http://forum.slashdev.ca/ <p>Pam,</p> <p>Thank you SO MUCH for using the forums!</p> <p>I get a lot of comments on the BlackBerry development in Linux blog post from people asking for help. However, wordpress comments are the least fun thing to use for providing support.</p> <p>- Josh </p> http://forum.slashdev.ca/topic/4#post-7 Thu, 06 May 2010 07:15:05 +0000 pamepros 7@http://forum.slashdev.ca/ <p>Nevermind, I just got it to work, it was my jde path it had spaces and it messed up something, just changed it to a simple name. </p> http://forum.slashdev.ca/topic/4#post-6 Thu, 06 May 2010 07:07:32 +0000 pamepros 6@http://forum.slashdev.ca/ <p>Hi, I'm following your tutorials to get the BlackBerry JDE working in Ubuntu.<br /> I managed to get the simulator to work perfectly.<br /> Now I'm trying to get the eclipse to compile the project.
