http://dx.com/p/crius-co-16-oled-display-module-for-telemetry-debug-multiwii-fc-flight-control-board-blue-180386
with help from

and code from
https://github.com/hydra/UG2864HSWEG01/blob/master/data.c
The reason it doesn't work with the regular arduino Wire library and was also not discovered with i2cdetect, is that the display doesn't send ACK's back.
