(0.42 Inch White OLED Display -SSD1306, 72x40, SPI)

개요

  • 본 제품은 0.42 인치 흰색 OLED 디스플레이 -SSD1306, 72x40, SPI입니다.
  • SSD1306 디스플레이 드라이버를 탑재하였으며, SPI 인터페이스를 가지고 있습니다.
  • 3.3V/5V와 사용이 가능합니다.

특징

  • Resolution: 72*40
    Driver IC: SSD1306
    Color: white
    Brightness: Support 256-step adjustable brightness
    Communication interface: 4-wire SPI/IIC, default SPI
  • Interface Definition
    1.GND
    2.VCC: +3.3-5V
    3.SCL: SPI clock
    4.SDA: SPI data
    5.RES: OLED reset after power-on low level
           Reset once, then stay high
    DC: Data / Command Control Line
    CS: OLED SPI chip select, active low
     
    The 0.42 inch spi interface is modified to the IIC interface operation method
    The 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.
