Rock,

 Thanks for the heads up. I have updated the link as well as a few others that broke. Seems apple has changed the way you reference files from their mobile me service.

All,

 I have put some documentation together for those of you working on libraries for LCD displays. I have created a page in the playground with the API specifications http://www.arduino.cc/playground/Code/LCDAPI

I currently have both of my i2c LCD libraries compliant, and the standard LiquidCrystal libraries are compliant with the functions that are implemented.

I welcome any comments or suggestions on what has been done already.

I am interested in this also. Have too many other projects in the works now, but will keep an eye out here. There are some issues with the scales to keep an eye out for. Mostly the frames are tied to the positive side of the battery so that causes some issues when mounting them. Glad to see someone is working on this.

Changing the autorouter from the default of 50 to 20 did the trick. Thanks for everyones help.

I am laying out a new sheild, and have everything done in eagle. I have a few SMD parts and eagle does not seem to want to auto route to them. If I change the packages to dip's every thing works great. I have googled around and can not find the answer to this. Anyone have any suggestions.

Thanks,
Dale

Henry,

Glad if worked for you. Unfortunately I have not had any time to work with the Aurduino. Too much going on at work and home.

Try increasing the delays in the library. The web4 display is very sensitive to the delays. I do not have one of the new boards to test with.

I received an e-mail from Brian Brumfield that he ported the library to the Matrix Orbital LK162-12 displays. I uploaded his code as a zip file into my download area. I could not log into the wiki, but will upload it as soon as the login problem gets resolved.

I would suggest the pull up resistors on all the displays. I have had i2c things work with out them, but I have also had problems. The resistors do not hurt at all. I have been too busy to devote any time to the libraries, as far as adding other manufactures devices. The library is very portable and it should be easy to change and add other displays. If you do please forward me a copy and I will take the time to update the documentation and point to any user contributed libraries.

You can use the sprintf function to convert a float to a string.

I have not noticed this on either of my display. I wonder if it is a problem like with the keypad? I do not think it is the libraries, as there is nothing in them that could cause the problem. You might try adding some delays and see if that helps. Have you tried the demo that Ran wrote that uses the bar-graphs?

I asked Tony about this, and he said you would have to send it back, but the new code is not available to the public yet, he is still developing it, and I am sure he is waiting on me to test it.

I have seen this problem also.  I talked to Tony about it, and he was checking into it. I have a new board with beta firmware on it, but have not had a chance to play with it. My real jobs have been getting in the way.

I will forward this to him.

I have not used the keypad with an interrupt at all. I would fire a e-mail off to Tony at web4robots and see what he has to say. I have tested the keypad with both the web4robots, and the robot electronics, and have not noticed anything odd going on with either.

Lukas,

  Try powering the display up with nothing else connected and see what happens. Does the backlight come on when you power it up? If it does then it is getting power OK. I would contact Tony and web4robts and see what he has to say.
