Simple Frontlight Control

This basic example demonstrates how to control the frontlight/backlight brightness of the Inkplate 6Flick using simple function calls.

The frontlight allows for better visibility in dim environments while preserving the paper-like appearance of the e-paper screen.

---

Example Overview

This sketch shows how to control the brightness of the frontlight using setFrontlight() from the Inkplate API. You can control the brightness using PWM values from 0 (off) to 255 (maximum brightness).

#include "Inkplate.h"

Inkplate display; // Create the display object

void setup()

    display.begin();              // Initialize the display
    display.clearDisplay();       // Clear the screen buffer

    display.println("Frontlight test!");
    display.display();            // Refresh screen

    delay(1000);

    display.setFrontlight(0);     // Turn off frontlight
    delay(1000);
    display.setFrontlight(50);    // Set low brightness
    delay(1000);
    display.setFrontlight(150);   // Medium brightness
    delay(1000);
    display.setFrontlight(255);   // Full brightness
}

void loop()
{
    // Nothing to do in loop
}

setFrontlight()

Sets the brightness of the frontlight/backlight on the Inkplate 6Flick.

Returns type: void

Function parameters:

Type	Name	Description
uint8_t	level	Brightness level (0 = off, 255 = full brightness).

---

Notes

• The frontlight is automatically turned off after sleep or reboot, so be sure to call setFrontlight() again in setup() if needed.
• The frontlight controller uses PWM to set brightness, so intermediate values may cause visible flickering depending on environment lighting.
