lcd mcu

i see alot of pics with lcd built in but what lcd would you use for it? Like they have segments and stuff

 

[AtomSoft]

ok maybe i should explain better lol

This is the PIC: PIC16F946

What LCD would one use? How and where to get it. Those are my questions.

Those are made to drive LCD glass directly. You can buy LCD displays without a controller very cheaply (for instance). They have to be driven in a very precise way or they won't work and can actually be damaged (I think). MCUs with LCD control do that without you having to do all the work yourself.

I have a couple displays I've been meaning to play with. There's one in this picture:

Was going to do all the timing and AC output myself. Since then I bought a PIC 16F917 that has LCD capability, but still haven't got around to doing it.

Also, have not got around to hooking up the bare glass displays. After seeing one of Blueroom's project's, was going to hookup to an idle 16f917 debug board. This 4 digit Lumex model does static or 1/2 bias, so seemed do-able with the 16f917 in the 1/2 bias mode. Varitronix is another major manufacturer.

That's one of the two displays I bought. The other is this one, which is the one in the picture above, I think.

A while back Bill got me interested in trying a bare glass LCD. In December I ordered the LCD but was shipped the wrong display.

Have two firmly implanted into antistaic foam with original bubble wrap and tape still intact. Oh well, one of these days........

the one with no DIP how do u connect it?

Huh? All the displays we've talked about in this thread are DIP style. If it has a different kind of connection you just do what you have to.

oh i didnt notice the right side of datasheet. It is DIP lol thanks.

Where would one go to create custom LCDs. I know that has to cost alot.

To China! I actually have no idea, but ya, I'd think they'd want a fairly large minimum order.
