europi_display

Classes and definitions for interacting with the OLED display

class europi_display.Display(*args: Any, **kwargs: Any)

A class for drawing graphics and text to the OLED.

The OLED Display works by collecting all the applied commands and only updates the physical display when oled.show() is called. This allows you to perform more complicated graphics without slowing your program, or to perform the calculations for other functions, but only update the display every few steps to prevent lag.

To clear the display, simply fill the display with the colour black by using oled.fill(0)

More explanations and tips about the the display can be found in the oled_tips file oled_tips.md

centre_text(text, clear_first=True, auto_show=True)

Display one or more lines of text centred both horizontally and vertically.

Parameters

  • text – The text to display

  • clear_first – If true, the screen buffer is cleared before rendering the text

  • auto_show – If true, oled.show() is called after rendering the text. If false, you must call oled.show() yourself

Parameters
