## How to Use Example
|
|
|
|
|
|
|
|
|
|
Before project configuration and build, be sure to set the correct chip target using:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
idf.py set-target <chip_name>
|
|
|
|
|
```
|
|
|
|
|

|
|
|
### Build and Flash
|
|
|
|
|
|
|
|
|
|
Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.
