Interface Definition1.GND2.VCC: +3.3-5V3.SCL: SPI clock4.SDA: SPI data5.RES: OLED reset after power-on low levelReset once, then stay highDC: Data / Command Control LineCS: OLED SPI chip select, active lowThe 0.42 inch spi interface is modified to the IIC interface operation methodThe resistor SPI is removed and soldered to the ICC position; the ends of R5 are shorted by tin, and the dc and cs pins are grounded; the res pin is controlled by an io to complete the reset; the reset method first keeps the RES pin at the level of 20ms; The RES pin is operated with a high level to complete the reset operation, and then the OLED is initialized; thus, ic=SDA can be communicated with iic.
