## What it is
Magic ePaper Firmware is open-source C firmware for controlling FOSSASIA's e-ink (e-paper) displays on microcontrollers. It acts as a bridge between an NFC reader and the epaper display, forwarding display commands and data over SPI via ISO15693 NFC messages, with support for text, image, and custom graphics rendering at low power.

## Use cases
- render content on e-ink displays from a microcontroller
- drive an epaper display via NFC using an ST25DV tag
- build low-power smart signage with e-paper
- create battery-powered dashboards with e-ink screens
- add support for generic SPI-based e-ink displays
- send display commands and image data in chunks over iso15693

## When to choose
- you are building with FOSSASIA's epaper hardware or compatible SPI e-ink panels
- you need an NFC-to-display bridge with energy harvesting
- you want a customizable, low-power open-source firmware for e-ink projects

## When to avoid
- you need a high-level display library for Linux SBCs or desktop environments
- your display uses a driver chip not supported by the firmware and you cannot write a driver module
- you need rich animated or color rendering beyond e-ink capabilities
