## 🛠️ Troubleshooting
If you encounter the following runtime error:
`
i2c: CONFLICT! driver_ng is not allowed to be used with this old driver
`
This error occurs due to a conflict between the legacy I2C driver and the newer driver model (`driver_ng`).
### ✅ Solution
Enable the following option via `idf.py menuconfig`:
`CONFIG_I2C_SKIP_LEGACY_CONFLICT_CHECK=y`
**Important**: This option is only available in the **latest ESP-IDF release branches**:
Pull the latest code from release branches.
- `release/v5.2`
- `release/v5.3`
- `release/v5.4`
- `release/v5.5`
- `master`
- If you're using an older ESP-IDF version, you can apply this [commit as a patch](https://github.com/espressif/esp-idf/commit/466328cd7e4c90c749a406d2bcee73f782ac0016) to add support manually.
