SSD1306 OLED MakeCode Package 
This is the MakeCode Package for SSD1306 OLED controller, based on the Adafruit Arduino library available here.
Hardware Setup
- Insert the OLED display into the I2C ports on the break out board.
Blocks
Initialize OLED Display
Initializes the OLED display.
Sets up the OLED display and prepares it for use by the micro:bit.
OLED.init(64, 128);This block must be placed before any of the show blocks.
Show String Without Newline
Displays a string on the OLED module without a newline.
OLED.showString1("hello, micro:bit!")The init block must be placed before this.
Show String With Newline
Displays a string on the OLED module with a newline.
OLED.showString2("hello, micro:bit!")The init block must be placed before this.
Show Number Without newline
Displays a number on the OLED module without a newline.
OLED.showNumber1(123)The init block must be placed before this.
Show Number With Newline
Displays a number on the OLED module with a newline.
OLED.showNumber2(123)The init block must be placed before this.
Clear Display
Clears the display.
OLED.clear()The init block must be placed before this.
Show Loading Screen
Displays a pre-made loading screen.
OLED.Loading_Screen()The init block must be placed before this.
Draw Outlined Rectangle
Displays an outline of a rectangle.
OLED.drawRectangle(x,y,w,h)The init block must be placed before this.
Draw Filled Rectangle
Displays a filled rectangle.
OLED.fillRectangle(x,y,w,h)The init block must be placed before this.
Draw Outlined Circle
Displays an outline of a circle.
OLED.drawCircle(x,y,r)The init block must be placed before this.
Draw Filled Circle
Displays a filled circle.
OLED.fillCircle(x,y,r)The init block must be placed before this.
Draw Line
Displays a line.
OLED.drawLine(x1,y1,x2,y2)The init block must be placed before this.
Progress bar
Displays a progress bar with a specified percentage of progress.
OLED.showProgress()The init block must be placed before this.
Example: Counter
The following code is a simple counter that displays an increasing number every second.
OLED.init(64, 128)
let item = 0
basic.forever(() => {
basic.pause(1000)
item += 1
OLED.showNumber(item)
})
