If you mean "too heavy" from a processor power point of view, well, no, that's not what I said. I said that it's too expensive to "sacrifice" 8 pins of the FoxBoard just to control a simple LCD. The pins could be used for more useful things. It's for sure not a "big deal" for the FoxBoard to control a LCD. If the FoxBoard would only have to do that, well, it would become an extremely lazy fox, I'm afraid... ;-) > > I'm newbe to use display could I ask you a tutorial on LCD? There's no such thing as a "tutorial on LCD". The only thing you need, are the specs of such device. If you look into the specs, you will see start-up sequences and algorithms which will tell you when to do what. That should be sufficient to control and master the whole LCD. Here you can find an excellent data sheet of the device you have: http://www.eio.com/hd44780.pdf Pls. read it carefully through and you will see that controlling such a device is really not something as rocket science... > I mean I'm able to choose a correct display and the correct way to work with that.. Well, if you're a bit patient, I'm busy working on a lot of I2C software component classes that can control different kinds of hardware. One of them will be a component that, using an I/O expander, will be able to control such type of LCD. But again, you have to have patience, as I have to do (many) other things too and I don't want to pinpoint myself to a target date. Life's sometimes already "hectic" enough... Best rgds, --Geert
