sample 1 hex download 点击链接后，页面上有3个按钮：“Raw”按钮，“Blame”按钮，“History”按钮，在“Raw”按钮上右键，另存为，进行下载。

sample 2 hex download 比sample 1多加了开始时设置画图显示为关闭，结束时再一次性显示画图的结果。而不是像第一次那样每次画图都显示，第一次每画一笔都发送数据去显示一次，那样效率有点低。

SSD1306 OLED MakeCode Package

This is the MakeCode Package for SSD1306 OLED controller, based on the Adafruit Arduino library available here.

Hardware Setup

1. 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

Displays a string on the OLED module.

OLED.showString("hello, micro:bit!")

The init block must be placed before this.

Show Number

Displays a number on the OLED module.

OLED.showNumber(123)

The init block must be placed before this.

Clear Display

Clears the display.

OLED.clear()

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)
})

Supported targets

• for PXT/microbit
