Simple Frontlight Control

Inkplate 4TEMPERA features a built-in frontlight, which allows the display to be visible in low-light environments. This page shows you how to control the frontlight using a simple sketch.

ℹ️

The frontlight brightness is controlled through the frontlight object. Call setState(true) to enable the frontlight circuit, then use setBrightness() with a value between 0 (off) and 63 (full brightness) to set the intensity.
