Interface definition:

 

1> GND (Power ground)

2> VCC (Power + 3.3-5V)

3> D0 (SPI clock line for SPI interface and IIC clock line for IIC interface)

4> D1 (SPI data line for SPI interface and IIC data line for IIC interface)

5> RES (OLED reset, OLED needs to be reset once after power-on)

6> DC (SPI data/command selection pin, used to set IIC address when IIC interface)

7> CS (OLED SPI chip select, active low, if you do not want to use must be grounded)

 

Package includes:

 

1 x 0.96 Inch OLED Display Module
1 x Acrylic bracket kit

Wiring method:

Wiring 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.

Wiring 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.

Wiring 3:

MCU analog IIC connection method:

IIC address:

DC is low = 0x78

DC is high = 0x7A

Generally DC grounding
 

Wiring 4:

MCU hardware IIC connection method:

IIC address:

DC is low = 0x78

DC is high = 0x7A

Generally DC grounding
