# RFP ESP32-S3 WROOM-1 N16R8 (3 x 106)

This repository includes a tracked PlatformIO target for the RFP ESP32-S3 WROOM-1 N16R8 nodes with three LED outputs and 106 pixels per output.

Build target:

- `rfp_esp32s3_wroom1_n16r8_3x106`

Default output pins:

- Output 1: `GPIO4`
- Output 2: `GPIO5`
- Output 3: `GPIO6`

Pins intentionally avoided:

- `GPIO0`, `GPIO3`, `GPIO45`, `GPIO46` for boot / strapping
- `GPIO19`, `GPIO20` for USB
- `GPIO33` to `GPIO37` because they are reserved by octal PSRAM / flash on `N16R8`
- `GPIO48` because it is used as the onboard status pixel

Build:

```powershell
python -m platformio run -e rfp_esp32s3_wroom1_n16r8_3x106
```

Build and upload:

```powershell
.\tools\flash_rfp_s3.ps1 -ComPort COM7
```

Build only with the helper script:

```powershell
.\tools\flash_rfp_s3.ps1 -BuildOnly
```

Local Wi-Fi defaults:

- Keep SSID and password in the ignored file `wled00/my_config.h`.
- If the file does not exist yet, create it with your local values:

```cpp
#pragma once

#define CLIENT_SSID "your-ssid"
#define CLIENT_PASS "your-password"
```

Important:

- The `3 x 106` bus layout is used as the default when the device has no saved `cfg.json`.
- If a board already has a saved WLED config, do a factory reset or erase settings once so the default bus layout is recreated.

Onboard status pixel on `GPIO48`:

- `green blinking`: DDP realtime active
- `green solid`: network connected
- `blue blinking`: AP / setup mode active
- `red fast blinking`: Wi-Fi configured but currently disconnected
- `amber fast blinking`: network connected, MQTT configured, but MQTT not connected
- `off`: idle / no status to show
