# p4 Gemini chat (ESP-IDF)

Parent tree for Gemini-enabled UI on Espressif’s **ESP32-P4-class** toolchain.

Main firmware: **`p4_gemini_chat/`**

| Path | Notes |
|------|-------|
| `p4_gemini_chat/` | CMake + `main/` sources, `sdkconfig`, `managed_components` |
| `components/` | Shared component libraries |
| `ai brains/` | Prompt / persona assets |
| `build/` | Local IDF artifacts (keep untracked) |

## Build flow

Install **ESP-IDF** matching Espressif P4 toolchain requirements, activate environment, then:

```bash
cd p4_gemini_chat
idf.py set-target esp32p4   # confirm precise target alias with Espressif release notes
idf.py fullclean build flash monitor
```

Export `GEMINI_API_KEY` (or whichever env var main sources expect) securely—never bake keys into firmware images.
