# how to connect i2c peripherals to digispark Attiny85

I am new to micro controllers and I have problem with understanding and connecting I2C devices to Attiny85 digiSpark micro controller.

According to this picture SDA and SCL are on the same pin and I am confused how can I connect any i2c device to this controller. Please can somebody help me in order to achieve this?

To be more specific, I have oled display like this one and I want to connect it to digispark.

If somebody can help me I will appreciate that! Thanks

• SCK is a name of the clock signal in SPI protocol. SCL is the clock in the I2C. This pin is just multiplexed. I2C is using two signals SCL/SDA only (Well, connecting GND would be a good idea too). – Eugene Sh. Jul 4 '17 at 14:01
• sorry miss typed. I just realized that I made mistake with pinouts. Can you please help me with documentation for connection digispark and oled display? There are no concrete results when I am googling :? – hogar Jul 4 '17 at 14:06
• So on the picture SCL and SDA are on different pins. – Eugene Sh. Jul 4 '17 at 14:07
