U8g2 is a monochrome graphics library for embedded devices.

• Supported Display Controller: SSD1306, SSD1322, SSD1325, SSD1606, SH1106, T6963, RA8835, PCD8544, UC1604, UC1608, UC1610, UC1611, UC1701, ST7565, ST7920, LD7032, KS0108 (see here for a full list)
• The Arduino library U8g2 can be installed from the library manager of the Arduino IDE.

U8g2 also includes U8x8 library. Features for U8g2 and U8x8 are:

• U8g2
  • Includes all graphics procedures (line/box/circle draw).
  • Supports many fonts. (Almost) no restriction on the font height.
  • Requires some memory in the microcontroller to render the display.
• U8x8
  • Text output only (character) device.
  • Only fonts allowed with fixed size per character (8x8 pixel).
  • Writes directly to the display. No buffer in the microcontroller required.
