## 🔧 How to Use This Template
|
|
|
|
### Immediate (Development)
|
|
1. Clone repo
|
|
2. Run `pio run -e esp32-s3-freenove` to build
|
|
3. Flash with `pio run -e esp32-s3-freenove --target upload`
|
|
4. Follow QUICKSTART.md to test each module
|
|
|
|
### Short-term (Integration)
|
|
1. Copy `include/` and `src/` to your HaleHound project
|
|
2. Add `[env:esp32-s3-freenove]` to platformio.ini
|
|
3. Update `board_config.h` GPIO if your board differs
|
|
4. Implement attack modules (WiFi, BLE, SubGHz, RFID)
|
|
|
|
### Medium-term (Optimization)
|
|
1. Profile with heap traces and CPU sampling (see PERFORMANCE.md)
|
|
2. Tune memory allocation per module
|
|
3. Enable/disable features via board_config.h flags
|
|
4. Optimize SPI frequency, CPU frequency, power draw
|
|
|
|
### Long-term (Deployment)
|
|
1. Set PIN lock in settings
|
|
2. Configure OTA firmware updates (built-in support)
|
|
3. Populate SD card with payloads (.sub files, wordlists)
|
|
4. Deploy with proper authorization and documentation
