What considerations must I take in order to adapt the code, and also to make the proper physical equivalent connections on my Arduino? socaldt on "Scrolling text" http://forum.slashdev.ca/topic/38#post-95 Sat, 17 Sep 2011 07:42:52 +0000 socaldt 95@http://forum.slashdev.ca/ Hey Jiggak, I know you have stop updating your library, but hopefully you still check this forum. I found your library and it works for me. However, I tried to scroll my text but no luck. It scrolls but it appears pixelated. If I do not use any delays, the the message would just flash by the LCD. It looks like it is not fast enough. I can see the old character before it gets update with the new one. Has this happened before? I tried it on both of my LCD but it is the same. I used lcd.entry_mode(ENTRY_SHIFT); and tried to display it using lcd.print(msg);. I also tried for-looping it, but neither mode can display the message without distorting. Any suggestions would be appreciated. Thanks!

I also have a verysimple javac HelloWorls.java ready to test. I can not find exactly how to use this wonderful tool - I am not using ANT at the moment. Can anyone point me to a list of instructions on what to do to invoke the preprocessor from the command line? Thanks, Adam benvd on "Trouble with bjdwp (jdb connects, eclipse doesn't)" http://forum.slashdev.ca/topic/8#post-25 Mon, 06 Dec 2010 11:20:48 +0000 benvd 25@http://forum.slashdev.ca/ 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. 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. 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. 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). Any suggestions?

This way it is not regocnized as a library Am I doing something wrong? Thanks pamepros on "Can't get the HelloWorld to compile with ant" http://forum.slashdev.ca/topic/4#post-6 Thu, 06 May 2010 07:07:32 +0000 pamepros 6@http://forum.slashdev.ca/ Hi, I'm following your tutorials to get the BlackBerry JDE working in Ubuntu. I managed to get the simulator to work perfectly. Now I'm trying to get the eclipse to compile the project. I copied your helloworld example,changed my jde.home and simulator.home to mines, but when I try to compile it says: Buildfile: /home/pam/workspace/HelloWorld/build.xml build: [rapc] Compiling 1 source files to hello_pam.cod [rapc] javac: invalid flag: 5.0.0/lib/net_rim_api.jar" [rapc] Usage: javac <options> <source files> [rapc] use -help for a list of possible options [rapc] Error!: Error: java compiler failed: javac -source 1.3 -target 1.3 -g -O -d /tmp/rapc_0ab943d8.dir -bootclasspath "/home/pam/lib/BlackBe ... BUILD FAILED /home/pam/workspace/HelloWorld/build.xml:16: Java returned: 97 Total time: 523 milliseconds Do you have any idea why? Thanks! Pam evil_md on "Custom Characters" http://forum.slashdev.ca/topic/3#post-4 Tue, 09 Feb 2010 18:00:21 +0000 evil_md 4@http://forum.slashdev.ca/ I'm completely new to the world of arduino, but I've been running your library and its been working great for me. However I'm not completely clear on the custom character aspect, so was hoping you would be able to give me a short example outlining the definition of a character, and then the proceedure for printing the character to the LCD. Cheers for any help! jkittle99 on "There's nothing here?" http://forum.slashdev.ca/topic/2#post-2 Thu, 07 Jan 2010 23:15:37 +0000 jkittle99 2@http://forum.slashdev.ca/ Seriously? Ok so let me be the first, then. I'm using Arduino 17 on a mac. The library works fine. I've wired up a 2x16 Winstar WH1602B display (it has an RGB backlight - mega cool) and I'm running in 4 bit mode. Hello world works fine on line 1, but nothing goes to line 2. Why is "move_to" not highlighted? My complete code: /* * Simple hello world program in 4 pin mode. */ #include <Lcd.h> // LCD module is 16 columns wide, use 4 pin mode Lcd lcd = Lcd(16, FUNCTION_4BIT); char msg[] = "Hello, World!"; void setup() { // for the sake of demonstration change pin assignment lcd.set_ctrl_pins(CTRLPINS(1,2,3)); // RS->1, RW->2, E->3 lcd.set_data_pins(_4PINS(4,5,6,7)); // D4->4, D5->5, D6->6, D7->7 lcd.setup(); // setup arduino and initialize LCD lcd.move_to(1,2); lcd.print("Line 2"); } void loop() { lcd.home(); // return cursor to home possition lcd.print(msg); // print the ever so familiar message }
