|
**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):
|
|
|
|
```bash
|
|
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](../README.md) for ESP32-C3 ↔ PN532 and SD wiring.
