Update 7" screen 
- system page to new button names "HOTSPOT ON/OFF"
- added some linux files to make use of them as example
  files in "/usr/local/sbin/"

cf96c99103
Update 7" screen 
- duration gets calculated with timer instead of just reading the
  seconds and minutes from RTC, this is now more precise but it
  will still not display the exact same time as in the web dashboard
- the code of S0 was altered a bit, moved around this and that and
  removed some variables and added a few other together with some
  more timers
- Also the screen got tested on Pi-Star without NextionDriver and
  the display (DMR screen) works fine; as for what I can say...

# Useful files to keep on your Raspberry Pi
Use these files as examples and modify them to fit your needs.
Place the executable files in `/usr/local/sbin` and save `index.txt` as
`/root/index.html`.
## index.txt
This file contains the website that is shown when you stop the dashboard. It gets
copied into the webroot of your webserver -- make sure your webserver reads
`index.html` files **before** `index.php` files.
## dashboard
Executable file. Make sure to `chmod +x` this file.
Start or stop the dashboard with this command. This toggles the systemd service
- php7.3-fpm.service
Usage:
```
/usr/local/sbin/dashboard {on|off}
```
## hotspot
Executable file. Make sure to `chmod +x` this file.
Start or stop your hotspot. This toggles the systemd services
- mmdvmhost.timer
- mmdvmhost.service
Additionally it starts or stops the dashboard command mentioned above.
Usage:
```
/usr/local/sbin/hotspot {on|off}
```
### Start and stop the hotspot via Cron
Place these lines in your `/etc/crontab` to automatically start and/or stop
your hotspot.
```
30 6 * * 1-5 root /usr/local/sbin/hotspot off
0 18 * * 1-5 root /usr/local/sbin/hotspot on
```
That might stop the hotspot at 6:30 and start it again at 18:00, Monday to Friday.
## shrinklog
Executable file. Make sure to `chmod +x` this file.
This command shrinks the MMDVMHost log file to a limited number of important
lines.
The code of this was primarily taken from [Pi-Star][shrinklog] and modified.
[shrinklog]: https://github.com/AndyTaylorTweet/Pi-Star_Binaries_sbin/blob/master/pistar-hourly.cron
Usage:
```
/usr/local/sbin/shrinklog
```

## code_excerpts
Okay, usually you go and look into the HMI files and get the code from there.
But, not everyone is a code so I spent another hour installing those nasty
Nextion editor (had to find out which versions works with these files since
I never touched those files since I created them back in 2019/2020/2021- I
really don't know when that was exactly...
So this folder exists only for one purpose: to let people get an idea of what
they have to work when trying to edit these files.
Also it might be easier to review the code in case I have to look at (parts of)
it again. (I hope not)
### Important / Wichtig
**Please, this code is far not complete**, it is an excerpt taken from the
HMI files and it only exists to have a place that can be referred without
having to download the HMI files and open them with the Nextion Editor.
Sidenote: I think I used the LTS version.
