D1 Robot... lights up but nothing I have the Arduino shield described here, I have run the example code compiled to the device, both v1 and 1.1 example, and it shows nothing whatsoever on the screen.

Is there a special trick to initializing this or did I yet again get a lemon that will not display anything?
I got one of the D1 Robot version 1 from AllElectronic and I had to adjust the contrast before I could see the words on the display.
