Henk,

               I also use that product and the library.  You need to install the ByVac library either into the existing libraries folder or in a folder of your own.  If you find the Arduino folder then underneath it are various sub folders, one called libraries, you can install the ByVac library there.  Alternatively there will be a folder called something like mysketches where your Arduino sketches are stored.  You can create a sub folder under the sketches folder, I called mine libraries, and install the ByVac library in the folder you create.

The latter method of creating a separate folder for libraries that you add is that they are kept separate from the standard Arduino folders.

Thank you bobcroft, for the fast response.

Question:

There are several files,  I2CLCD.cpp,I2CLCD.pde and I2CLCD.h.

Do I have to copy them ALL into the new mysketches/libraries folder ?

Have a nice sunday

Henk

Henk,

The files that go into the library are those ending in .ccp and .h.  The .pde file is the 'sketch' that contains the program code you wish the Arduino to run.  The newest version of the Arduino IDE is version 1 (there may be sub version numbers too like 1.0.1) this version uses the file extension of .ino.  It is better, if you are new to Arduinos to try and use the newest version, in my opinion anyway.

I did a bit of research into the ByVac part you have, the BV4506.  This is a 3 * 4 key pad interface and not an LCD interface, therefore the I2CLCD files are not required for this interface.  I am guessing you have an older library for this part because the makers ByVac have now made the BV4506 obsolete and I could not access the library for it.  If you were to use this part to interface the key pad to the Arduino then you would need to interface the LCD in some other way.  There is a standard library in the Arduino libraries folder for LCD's.

The part I have is the BV4618 which is a combined key pad and LCD interface.  If you are able to I would buy one of these and then you can interface both key pad, 3*4 or 4*4 and an LCD to the Arduino.  You can also drive the interface with serial from Arduino or PC or I2C so it is more versatile  Once you have gained confidence with the BV4618 then you could go back and maybe use the 4506 for another poject.  I am happy to help where I can with the BV4618 because I have one and in fact I am using it for my current project.

My set up for the files is as follows;

C:\Arduino1\MySketches\Libraries\BV4618_I\examples.

The folder BV4618_I  contains a sub folder called Examples and the .cpp and .h files.  The I on the end of BV4618 denotes this is the I2C library as opposed to the BV4618_S which is the serial library.

The standard libraries supplied with Arduino are in the  C:\Arduino1\Libraries folder.

When you make changes to the Arduino libraries you need to close the IDE and re-open it for the changes to be recognised by the IDE.  When correctly installed you should be able to open 'File' in the Arduino IDE and then click on Examples and you should see the BV4618_I folder listed and with in this folder will be the ino files.

If you modify the example files you have to save them with a new name because the original files are read only.  Thus you might call your file myBV4618test.ino and save it in the MySketches folder.

Many thanks for your information bobcroft

A little bit late, but out of my heart.
