class experimental.screensaver.OledWithScreensaver(enable_screensaver=True, enable_blank=True)

A wrapper for europi.oled that provides automatic screensaver & blank if enabled

The notify_user_interaction() method should be called in the ISR for any events that should interrupt or defer the screensaver/blank

Set .enable_screensaver or .enable_blank to False to disable the screensaver/blanking activation completely (though if you do that, just use europi.oled instead of this class)

Parameters

• enable_screensaver – If true, the screensaver will activate when needed

• enable_blank – If true, the screen will blank after the screensaver has been active for a while

is_blank()

Is the screen blanked due to inactivity?

is_screenaver()

Is the screensaver currently showing?

notify_user_interaction()

Notifies the screensaver subsystem that the user has physically interacted with the module and that the screensaver should defer/shutdown as appropriate

class experimental.screensaver.Screensaver

A screensaver for the EuroPi

This class’ draw() function should be called from inside the application’s main loop to draw the screensaver.

At regular intervals the EuroPi logo will be drawn to a random location on the screen.

Alternatively draw_blank() will simply clear the screen

draw(force=False)

Draw the logo to a random position on the screen

If the current ticks_ms is an even multiple of the screensaver interval, or the force paramter is True, we will draw. Otherwise this does nothing

Parameters

force – Force the logo to be drawn, regardless of the current ticks

draw_blank()

Blank the screen completely
