Autostart.py script support

[prasimix]

Add possibility to run autostart.py MicroPython script on power up/restart if its exists in /scripts folder. Add the following:

• DISPlay[:WINDow]:HOMe command to display home page when script execution is done
• Option to enable/disable execution of the script, default is disabled
• Option to override script execution to stop execution of faulty script (e.g. if encoder switch is active during power up). Display message in this case like this: Auto script execution has been skipped. Do you also want to skip all future executions?
• Autostart a script in profiles (with skip) #214: I would like to see an auto start option if the BB3 power up or restarts, this should also be saved in profiles so you can setup different start scenarios.
• Autostart a script in profiles (with skip) #214: If an autostart script is detected, there should be a message and ‘skip’ button so the user sees this will happen and gives the option to skip the script.
• Add new SCRipt SCPI subsystem (see below)

Combine with #214?

The first item also relates to #126. If the script doesn't start a dialog, but runs in background, the user cannot get control back?

To manage all these possiblities maybe an tile/menu to the systems setting where the user can manage autostart but can also manage running/closing scripts instead of the overlay dialog?

SCPI commands:

- SCRipt:RUN {script_file_path}
    
  Runs script file.

  {script_file_path} is quoted string. Contains a full path to the script file, for example: "/Scripts/Hello world.py"

- SCRipt:STOP

  Force stopping of the currently running script. Useful in case when script got stuck.

- SCRipt:RECall {script_file_path}
- SCRipt:RECall?

  Sets/selects auto run script. 

  {script_file_path} is quoted string. Contains a full path to the script file, for example: "/Scripts/AutoStart.py"

  Query returns selected auto run script or "" if none selected.

- SCRipt:RECall:CLEar

  Clears/deselects auto run script.

- SCRipt:RECall:CONFirmation
- SCRipt:RECall:CONFirmation?

  Enables/disables confirmation popup.

To stop currently running script that got stuck you can also press both encoder and user switch on the front panel.

[fietser28]

Are SCRipt:RECall and CONFirmation part of the profile. E.g. selecting a different profile also sets a different script?

[mvladic]

Yes.

[fietser28]

Setting RECall and CONFirmation will be possible in the profile settings dialog?
Is this a good place to add this there?

We added a new Scripting section in Settings:
