Full updates only

The Spectra 6 panel on Inkplate 7SPECTRA takes full-screen updates only: the library has no partialUpdate() for this board. Every change goes through display(), which sends the whole frame buffer and refreshes the whole panel.

To change part of the screen, redraw it in the frame buffer and call display() again. The RTC alarm and battery voltage examples do exactly that: they clear the buffer, draw the new values and refresh the whole screen, once a minute and every 10 seconds.

display.display(bool _leaveOn = 0)returns void

Sends the whole frame buffer to the panel and refreshes it. With _leaveOn set to true, the panel supply stays on after the update; by default it is switched off.

ReturnsNothing.
