    I am trying this display on my Arduino. I hooked up the power and LED light power to the 3.3V, and the data,e,rs,etc lines to the digital outputs. The contrast is done with a poti. I wrote up some testing code that should just print one line, wait a second, clear and print a different line. The funny thing is, the contrast changes dramatically depending on what is being displayed, to the point where I initially thought one line wasn’t being printed at all and the other one was. Has anyone had a similar problem with this display?

No public wish lists :(
