💡 Hint

Common Mistakes

Using SPI or UART which are different communication protocols.

busio.I2C initializes the I2C bus using the SCL and SDA pins.

Fix the error in the code to create the display object with correct width and height.

Raspberry Pi

display = SSD1306_I2C([1], 64, i2c)

💡 Hint

Common Mistakes

Using 64 as width which is actually the height.

The common OLED display size is 128x64 pixels, so width should be 128.

💡 Hint

Common Mistakes

Using clear() which is not a method in this library.

Calling update() instead of show() which is the correct method.

Calling fill(0) clears the display buffer, and show() updates the screen.

5fill in blank

hard

Fill all three blanks to draw text on the display and update it.

Raspberry Pi

display.text([1], 0, [2], 1)
display.[3]()

Drag options to blanks, or click blank then click option'

A"Hello, Pi!"

Cshow

D20

💡 Hint

Common Mistakes

Using 20 for y which might place text too low or off screen.

Forgetting to call show() to update the display.

text() draws the string at x=0, y=10 with color 1, then show() updates the display.
