Newhaven Display Issues
« on: December 08, 2018, 05:59:34 AM »
I am a newbe who is attempting to interface with a LCD for the first time. I ordered three Newhaven 2 x 16 displays, part number NHD-0216BZ-FL-YBW.

I am having some trouble getting the thing to display anything. I was told by a Newhaven engineer that if contrast is set correctly that it will light up the first line when power and ground are connected.

I connected the first one according to the pin lables on the board. it flashed some crazy gunk on the display and then went quiet, never to twitch again. I then noticed that the pin marking do not match the data sheet. Upon contacting Newhaven, I was told that the data sheet was correct and to disregard circuit board labeling.

The data sheet calls for a 10~20K variable resistor. I don't have a variable resistor in the shop so connected several resisters and series. I connected the contrast pin to ground throuh 20K of resistors... no display. I connected it to ground through 10K of resistors... no display. I tried it at resistance levels between 10 and 20 K with no display. Any suggestions will be appreciated

I assume that 10~20K, as indicated in the data sheet means a pot with minimum resistance of 10K and maximum resitance of 20K, is this correct?
