REGIS, i know this is not in the library , but i found this from Marcus Fazzi and tried bit received an error

Hi Fred, Is this one of the examples provided ? I can't find it ...

[fcwpinguino]

Regis Marcus had this on his web page using it with a pinguino 4550

Ok, I think I've found it here : http://www.fazzi.eng.br/2010/12/pinguino-i2c-oled-display.html The code is a bit old and since we made an Oled library ... Which display do you have ? SSD1306 ? If so, connect your display to the i2c pins of your board. Tell the IDE you want to use the i2c interface :

define DISPLAY (SSD1306_I2C | SSD1306_128X64)

and init the display with : SSD1306.init(i2c_addr_of_your_display);

Regis I will try this tonight whe. I get home Thank you Fred
