lcd - show messages on an LCD display¶
This plugin is normally called in an action that is triggered whenever a new environment/messages/message
appears. It displays that message on an external LCD display.
See the say plugin for an alternative way to present messages to the user (by speaking them).
requirements¶
To use the plugin as-is (as opposed to using it as sample code for other ways to display messages) requires a command line tool lcdecho
. This tool is available as part of the [iotsa Display Server], URL to be provided later.
actions¶
One action, to display the content of any element inside environment/messages
whenever it changes.
