emulator_firmware

Emulator module for the dual-PN532 NFC system: receives NFC captures over ESP-NOW, drives PN532 emulation, and logs to SD card when available.

Build

Built via PlatformIO from the workspace root (same platformio.ini as the listener):

cd ..
pio run -e emulator
pio run -e emulator -t upload

Requires ../common/ for nfc_protocol.h and related sources.

Hardware

See the root README for ESP32-C3 ↔ PN532 and SD wiring.
