OLED display 128 x 64 SPI - White

This OLED display has white pixels on a black background. The display communicates over SPI / I2C and can be powered with 3.3V.

OLED (Organic Light-Emitting Diode) means that the screen consists of all small LEDs (each pixel equals 1 LED). As a result, the display does not require a backlight and is much more economical to use. In addition, this gives a much higher contrast, making this display very clear and legible despite its size.

Interface

• GND (Power ground)
• VCC (Power 3.3V - 5V)
• D0 (SPI clock line for SPI interface and IIC clock line for IIC interface)
• D1 (SPI data line for SPI interface and IIC data line for IIC interface)
• RES (OLED reset, OLED needs to be reset once after power-on)
• DC (SPI data/command selection pin, used to set IIC address when IIC interface)
• CS (OLED SPI chip select, active low, if you do not want to use must be grounded)

Connection

• Method 1:
  MCU hardware SPI connection method:
  If there is only one device on the SPI bus, you can directly ground the CS of the OLED screen, which saves an IO.
• Method 2:
  MCU IO analog SPI connection mode:
  If there is only one device on the SPI bus, you can directly ground the CS of the OLED screen, which saves an IO.
• Method 3:
  MCU analog IIC connection method:
  IIC address:
  DC is low = 0x78
  DC is high = 0x7A
• Method 4:
  MCU hardware IIC connection method:
  IIC address:
  DC is low = 0x78
  DC is high = 0x7A
