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
3 x 0.96 Inch OLED Display Module
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
