Set GPIO pins
```bash
pinctrl set 6 pd
pinctrl set 12 pd
pinctrl set 13 pd
pinctrl set 16 pd
pinctrl set 19 pd
pinctrl set 20 pd
pinctrl set 22 pd
pinctrl set 27 pd

### Configuration
To add a config, create a text file in the ~/.totp directory (if it doesn't exist then create it). The name of the file will be what is populated on the device.<br>
Ex: "google.txt" will be displayed as "google"<br><br>
