How do I change i2c pins?
I am trying to use ssd1306, my pins are 12 and 13, I use I2C oled 0.96 from ebay

How do I init the pins and use adafruit or ug8 with my pins?

- Sun Mar 29, 2015 4:57 am #12908 you can init i2c with this command "Wire.pins(0, 2);" but u8g and adafruit library not working yet

I like ESP8266 and ESP8285 and ESP32

Code: Select allWire.pins(12,13);

Also, which "adafruit library" are you referring to? I googled quite a lot libraries by Adafruit, which one are you trying to get to work?

2. which i2c OLED sd1306 works? what can I use?
