Interface Definition
1> GND (Power ground)
2> VCC (Power supply3.3~5V)
3> SCL (SPI clock line when SCL,SPI interface, IIC clock line when IIC interface)
4>SDA (SPI data line for SPI interface ,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)

Important note: OLED displays are different from LCDs; OLEDs are self-illuminating; so there is no backlight, and the screen will not react when only power is applied; there must be a correct operation of the program to display them. Please pay attention to this.
