Hi,
[I am fairly new to Arduino, I have done quite some googling, but I didn't find an answer to my problem].

I have an Arduino Uno (R3) and a Grove OLED Display (http://www.seeedstudio.com/wiki/Grove_-_OLED_Display_128*64)

I have connected the display to the power and Analog pins 4/5 for SDA/SCL respectively.

To get started, I would like to use the demo code from http://www.seeedstudio.com/document/_128x64_xypic.zip

When I load this from the Arduino 1.0.1 (or 1.0) software the display doesn't display anything. Sometimes it briefly flashed.  This required to change all the calls to Wire.send to Wire.write which has changed its name with Arduino 1.0.

However, when I load this code in Arduino 0023 and upload it to the device everything works perfectly. The display shows some text and logos (as expected from the demo code).

My impression is that something else changed, probably in the Wire library which I am not aware of. Any hints?

Thanks a lot.
thomas

Hi everyone,

I solved the mysteries. It works with the new examples provided on the webpage
