2.08 inch OLED Display 256*64 pixels - White - I2C

An OLED display with I2C communication. This display works on 3.3V, so use a level converter if you have a 5V microcontroller.

See the following page for an Arduino library: U8G2 Library
In the examples there are many possible drivers, however the SH1122 with I2C is not among them.
You can use this display with one of the following configurations:

Page buffer with hardware I2C:

U8G2_SH1122_256X64_1_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE);

Full buffer with hardware I2C:

U8G2_SH1122_256X64_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE);

Page buffer with software I2C:

U8G2_SH1122_256X64_1_SW_I2C u8g2(U8G2_R0, /* SCL=*/ SCL_PIN, /* SDA=*/ SDA_PIN, /* reset=*/ U8X8_PIN_NONE);

Full buffer with software I2C:

U8G2_SH1122_256X64_F_SW_I2C u8g2(U8G2_R0, /* SCL=*/ SCL_PIN, /* SDA=*/ SDA_PIN, /* reset=*/ U8X8_PIN_NONE);

For microcontrollers with little RAM memory, the page buffer configurations are recommended (otherwise it simply won't work). For microcontrollers with enough RAM (such as the ESP32) we recommend the full buffer configurations. Also keep in mind that the software I2C configurations are (much) slower than the hardware I2C configurations.

Finally, the I2C pins of microcontrollers with a GPIO multiplexer (such as an ESP32) can also be modified by using a hardware configuration and then adding the following at the very beginning of the setup() code:

Wire.begin(SDA_PIN, SCL_PIN);.
