Setup Guide

1. Software Installation

To program the e-Paper display, you will need the dedicated application. The application is named "NFC E-Tag".

For iPhone users: Download "NFC E-Tag" directly from the Apple App Store.
For Android users: Download the installable APK file from the official Waveshare wiki page. Search for "1.54inch NFC-Powered e-Paper (BB) wiki" to find the download link and detailed instructions.

Important Note for Android Users: Some older Samsung phones or specific Android models might experience compatibility issues. Refer to the Waveshare wiki for the most up-to-date compatibility information and troubleshooting steps.

2. Device Preparation

Ensure your smartphone has NFC functionality enabled. No physical preparation is required for the e-Paper display itself as it is battery-free.

Operating Instructions

1. Image Selection and Customization

Open the "NFC E-Tag" application on your smartphone. Select "1.54 inch paper B" within the app. You can then choose or create an image to display. The app allows for adjustments to optimize the image for the red, black, and white e-paper display.

2. Data Transfer

Once your image is ready, place the e-Paper display against the NFC chip area of your smartphone. The exact location of the NFC chip varies by phone model (often near the rear camera or center of the back). The app will typically provide an audio cue when the connection is established and data transfer begins.

The display refresh process typically takes a few seconds. If the display appears partially updated or "broken," reposition the e-Paper and attempt the transfer again. Multiple attempts may be necessary for a complete refresh.

3. Display Persistence

The e-Paper display retains the image indefinitely without power once the transfer is complete, thanks to its bistable nature.
