 Bigger Bigger  Smaller Smaller  Reset Reset

I just finished making myself my own really minimal/tiny Arduino on a stripboard, and now, I want to tag on an LCD to show some basic indication of numbers/status. I am familiar with standard 16X2 size HD44780 LCDs, but those are too bulky. So instead I'm considering a really small 8X1 LCD (I believe these are the 7-segment type, and come with just the glass).

If I want to interface my Arduino to an LCD like the one in the Digikey link below, how exactly do I get started? I am interested in a compact and inexpensive way. (Emphasis particularly on the "compact".)


Here is the product page for an example of this type of LCD: http://www.digikey.com/product-detail/en/VIM-878-DP-FC-S-LV/153-1113-ND/1118603

This also seems to be the same type of small LCD that you see on lots of electronics like digital calipers, basic calculators, etc. I am surprised that they are not very popular in the DIY community!

A lot of these displays require driver ICs. You have to be more specific, like a link to an ebay item or something on an online store.

@liudr,

I have added this information to my OP above just now.
Could you clarify with some details on the driver approach? What is an example of such a driver?

AARRGGHH  Why did you do this?  Now lidur looks like an idiot and anyone else trying to follow the thread is confused.

This might do but I might come back and change this post:

BTW, your display has no real spec sheet.

@floresta, this might have something to do with grade school education in this country. I keep seeing students listing some unknowns in the beginning of a problem and later solve these unknowns and fill up the list of unknowns in the beginning. It's impossible to deduce how the unknowns are solved. It not logic. I wasn't taught this sh*t growing up. It seems only the final answer was important.

They are.

Those are segment lcds, and depending on their complexity, they can be fairly consumed to drive, as most have no controller chips on them.

Once challenge with those chips is that they require ac to drive, and in the case of multi-com displays, you may have to produce bias to drive them. But they are fairly doable and sometimes you may run into chips with built-in lcd controllers for those displays.
