Dead display?

[mister_e]

Once the LCD is turn on and the Contrast PIN (VO) is set to gnd (or VDD i never remind) you'll see those cute black square.

It assume you properly wire your LCD E, RS, DATA, VCC, VDD, R/W lines too ;o]

Supplying 5V, COM, and V0 w/o the pic should give you black squares. (adjust contrast to both extremes to be sure)

If you get nothing chances are high the display is non-functional.

Thanks for the replys all. It looks road-kill dead. I've ordered another.

Thinking back, I think I traded a graphics display for this one (buddy of mine). I'll have to give him some @#*& when I see him next. :-)

I'll let you know if I get the other working.

Thanks again,

Just got in my new display. Works fine. Pulled out those precious hairs for nothing. Thought it was code... but should have known something was up when I didn't get all those "pretty" squares.

Thanks for the help!

I've been through the same thing before. First thing I do when I get the display is wire it up to see if there are squares. Then at least I know it worked correctly once.
