Batch Processing

Commands can be processed in batch one after another from .cmd script files located in the flash storage of the plate.
General rules when creating .cmd batch scripts:

  • can contain any command
  • empty lines are ignored
  • # or // can be used for comments
  • space or tab in front of a command is ignored
  • lines starting with { are processed as jsonl payloads
  • lines starting with [ are processed as json payloads
  • other lines are processed as <command> <payload>
  • CR, LF or CRLF line endings allowed
  • UTF8 encoding is required for special characters

To start a batch script, use run command.

System scripts~

If any of the following scripts is present on the filesystem, it will be run automatically according to the rules below:

  • L:/boot.cmd is executed when the plate has finished (re)booting
  • L:/online.cmd will be executed after connection to the network was successfull
  • L:/offline.cmd will be executed after connection to the WiFi is lost
  • L:/idle_off.cmd will be executed after idle state change to off (wakeup)
  • L:/idle_short.cmd will be executed after idle state change to short
  • L:/idle_long.cmd will be executed after idle state change to long

This makes it possible to disable or hide buttons, load a special offline page, dimming background, etc. See example.
