+# Basic example of clearing and drawing pixels on a SSD1306 OLED display.
+# This example and library is meant to work with Adafruit CircuitPython API.
+
+# Import all board pins.
+from board import SCL, SDA
+import busio
+
+# Import the SSD1306 module.
+import adafruit_ssd1306
+
+
+# Create the I2C interface.
+i2c = busio.I2C(SCL, SDA)
+
+# Create the SSD1306 OLED class.
+# The first two parameters are the pixel width and pixel height.  Change these
+# to the right size for your display!
+display = adafruit_ssd1306.SSD1306_I2C(128, 32, i2c)
+# Alternatively you can change the I2C address of the device with an addr parameter:
+# display = adafruit_ssd1306.SSD1306_I2C(128, 32, i2c, addr=0x31)
+
+# Clear the display.  Always call show after changing pixels to make the display
+# update visible!
+display.fill(0)
+display.show()
