## Filesystem
|
|
|
|
|
### Configuration
|
|
|
|
|
Use the config-example.json from the host folder and create here a config.json file.
|
|
|
|
|
### HowTo upload
|
|
|
|
|
Start Platform.io
|
|
|
|
|
Open a new Atom-Terminal and generate the filesystem with the following command :
|
|
|
|
|
```pio run -t buildfs```
|
|
|
|
|
Upload this new generated filesystem with:
|
|
|
|
|
```pio run -t uploadfs```
|
|
|
|
|
|
|
|
|
|
### Command pio
