SSD1306 OLED

The SSD1306 OLED is an I²C device in the LabWired part catalog. Its catalog type is oled-ssd1306. It connects to the MCU over I²C at the default address 0x3C. The catalog gives a supply range of 3–5.5 V. It has 4 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How to simulate the SSD1306 OLED in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the SSD1306 OLED (catalog type oled-ssd1306).
  3. Connect GND and VCC to the supply and ground of the board. Use a supply inside the catalog range of 3–5.5 V.
  4. Connect SDA and SCL to the I²C data and clock pins of the board.
  5. Run the firmware. It finds the part on the I²C bus at 0x3C and reads and writes it as on hardware.

Other parts at I²C address 0x3C

These catalog parts use the same default address. Two parts at one address cannot share one bus segment. A bus switch such as the TCA9548A puts them on separate segments.
