U8g2

U8g2: Library for monochrome displays, version 2

U8g2 is a monochrome graphics library for embedded devices.
U8g2 supports monochrome OLEDs and LCDs, which include the following controllers:
SSD1305, SSD1306, SSD1309, SSD1312, SSD1316, SSD1318, SSD1320, SSD1322,
SSD1325, SSD1327, SSD1329, SSD1606, SSD1607, SH1106, SH1107, SH1108, SH1122,
T6963, RA8835, LC7981, PCD8544, PCF8812, HX1230, UC1601, UC1604, UC1608, UC1610,
UC1611, UC1617, UC1638, UC1701, ST7511, ST7528, ST7565, ST7567, ST7571, ST7586,
ST7588, ST75160, ST75256, ST75320, NT7534, ST7920, IST3020, IST3088, IST7920,
LD7032, KS0108, KS0713, HD44102, T7932, SED1520, SBN1661, IL3820, MAX7219,
GP1287, GP1247, GU800
(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:

• 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 fit into a 8x8 pixel grid.
  • Writes directly to the display. No buffer in the microcontroller required.
