MegunoLink gets values for the map visualizer from specially formatted commands in serial streams. Each command must be surrounded by braces (‘{‘ and ‘}‘). Any text that is not within braces is ignored by MegunoLink. The MegunoLink Arduino library provides a simpler method for sending data to map visualizers.
The general format of table messages is: {MAP:channel-name|command|command data}
- The
channel-nameargument is optional. If present, it selects the table-channel. - The
commandargument is required. Only one command is supported currently:SET. - The value of the
command dataargument depends on the command.
Set Command
The SET updates the location a named marker on the map visualizer. The location name, latitude and longitude are provided in the command data, separated by pipe (‘|‘) characters.
Example:
{MAP|SET|Middle Earth|-37.835989|175.70061}: sets the position of a location named ‘Middle Earth’ to a latitude of -37.835989 and longitude of 175.70061.
