# micropython-ssd1306
|
|
This is a fork of the driver for SSD1306 displays which is hosted in the
|
|
[Micropython package](https://github.com/micropython/micropython). The purpose
|
|
of this fork is to make the driver available on PyPi and thus installable via
|
|
the upip package manager.
|
|
|
|
## Installation
|
|
Use the upip package manager:
|
|
|
|
upip.install('micropython-ssd1306')
|
|
|
|
If your board or your computer doesn't have an active internet connection you
|
|
can also clone this project on your local drive and copy the *ssd1306.py* to
|
|
your board.
|
|
|
|
## Example Usage
|
|
This shows an example usage on an *ESP32* board with an *SSD1306* display
|
|
with an resolution of 128x32 pixels. The display is connected via I2C. On the
|
|
*ESP32* the I2C pins are: SDA: 23, SCL: 22.
|
|
|
|
First we set up the I2C bus on our *ESP32* and scan for devices.
|
|
|
|
>>> import machine
|
|
>>> i2c = machine.I2C(sda=machine.Pin(23), scl=machine.Pin(22))
|
|
>>> i2c.scan()
|
|
[60]
|
|
|
|
This shows us that there is a device on address 60 which is 3C in Hex. That is
|
|
where our display is supposed to live. Now we create an object for our OLED
|
|
display.
|
|
|
|
>>> from ssd1306 import SSD1306_I2C
|
|
>>> oled = SSD1306_I2C(128, 32, i2c)
|
|
|
|
This is it. Now we can use our OLED display:
|
|
|
|
>>> oled.fill(1)
|
|
>>> oled.show()
|
|
|
|
This fills the whole display with white pixels. To clear the display do:
|
|
|
|
>>> oled.fill(0)
|
|
>>> oled.show()
|
|
|
|
Now we can also write some text:
|
|
|
|
>>> oled.text('Hello', 0, 0)
|
|
>>> oled.text('World', 0, 10)
|
|
>>> oled.show()
|
|
|
|
