EpdResetScreen()

Syntax

EpdResetScreen(wColor As Word)

Parameters

wColor — WHITE, BLACK, RED, YELLOW

Fills the screen with a single color.

This creates the effect of a screen reset — but the reset itself serves a more important purpose than just clearing to a color: it removes ghosting, the faint residual image that tends to accumulate on EPD panels from previous content.

(*) Calls a full screen update.

Note: During the reset, the screen will visibly flicker through several color changes.
Under the hood, this procedure repeatedly fills the GRAM buffer with a color and drives a full refresh — this is a genuinely slow process, by design.
