SSD1306 I2C pins? #242

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

Hi,

my OLED display has only VCC,GND,SCL,SDA pins

and I uncommented 

U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE);    // I2C / TWI 

Q: which pins I have to use?

thanks, but still no luck.

I purchased the display at eBay

There is also a link to software that works for me.

There is an updated version of u8glib attached to this thread:
http://forum.arduino.cc/index.php?topic=219419.15
I think it discusses the same oled display. Maybe this also solves your problem.

It works perfectly. I tested most of the examples

with uncommented U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NO_ACK);

and connected like described here

There should be no difference for the software. Just use these specific 
leonardo pins.
