With "quite a few hundreds of people stating" that they are having problems it should be easy for the OP to provide the information I asked for earlier.Don
but lots of people encountered troubles with it.
i will have to try with the 4 bit library
Quotei will have to try with the 4 bit libraryAre you referring to this library? http://www.arduino.cc/playground/Code/LCD4BitLibraryDon
Four out of the five links you posted were not in English but from what I can tell at least one of them had problems with the non-standard but well documented pin numbering. This would be a problem if you are trying to blindly follow Fritzing type diagrams. The English thread was dated in 2009, before Arduino 0017 introduced the current LiquidCrystal library. I believe that his problem turned out to be pins that were not soldered - and that is most likely what caused him to burn up his Arduino as well.Don't even think about using the old LCD4bit library. If you don't understand this: "An old 4-bit LCD library (now redundant)" or this: "Do not use this library" or this: "This was an unofficial, unmaintained Arduino library", then you should download the library and read the comments that are included with the source code. Even a non-technical person who does not understand any programming language can tell from those comments that the author of the code was not at all familiar with the LCD controller. Like many others he seemed to have hacked together some code that ran with his particular LCD module and published it for the world to see.Why don't you just follow this tutorial http://www.ladyada.net/learn/lcd/charlcd.html and get your LCD working like just about everyone else has been able to do? If you have problems then post a picture that shows your connections and we can go from there.Don
