Hi PaulS,
It is connected as the documentation in the GLCD library said, panel B. With an Adafruit datalogger in between.
The board is an UNO. I think it might be the analog pins that conflict with the datalogger.
The strange ting is that I can only get the GLCD working on 1 UNO board, out of 2 UNO's, 1 leonardo and 1 funduino MEGA 2560... This is a mystery to me. And this is without the SD shield, just the GLCD.
See GLCD documentation file for connections, panel B.
