On the back it says 2014 02 - does this mean it is the second version?
Most likely it means that the pc board was manufactured in February the second week of 2014.
After loading the test program the display just starts to flicker. The tact of flickering can be controlled by a DELAY() in the Void Loop().
That's interesting. Perhaps if we could see the program we could make an intelligent response.
There are many libs out there for this display - so far none have worked. Can anyone tell me which one will be right?
Didn't Sainsmart have any recommendations?
You might get some ideas here http://arduino-info.wikispaces.com/LCD-Blue-I2C and perhaps consider purchasing from a source that gives support in the future.:
