LCD Ribbon Cable Connection

by nateloaf on Wed Nov 10, 2010 1:05 pm

I am working on a device that uses the 20x4 LCD displays purchased here at Adafruit. They have all 16 pins in one row. I was wondering if anyone had any suggestions with respect to wiring these up in a manageable manner? Should I just use a HUGE 32 conductor IDC cable (using only one row of 16 pins). The only other way I can think of doing this would be to make a small board with a 16 pin IDC connector and a row of 16 female headers to plug the display in to.

I just thought I'd ask in case anyone out there with more experience has a suggestion.

Thanks

Wiring for displays is a major pain. You could do it with a 32 conductor cable as you describe, but if you look at the pins that are actually used, they are in 2 groups of 6. I find that two narrower cables are a lot more manageable.

But now Adafruit has their nify new LCD backpack that cleans things up even more. I'll be using these in future projects. http://www.adafruit.com/index.php?main_page=product_info&cPath=37&products_id=292
