|
|
* Enable:

|
* foglight = require("lib/foglight");
|
|
* - script reload
|
|
*
|
|
* Config:
|
|
* - vehicle foglight.port …EGPIO output port number
|
|
* - vehicle foglight.auto …yes = speed automation
|
|
* - vehicle foglight.speed.on …auto turn on below this speed
|
|
* - vehicle foglight.speed.off …auto turn off above this speed
|
|
*
|
|
* Usage:
|
|
* - script eval foglight.set(1) …toggle foglight on
|
|
* - script eval foglight.set(0) …toggle foglight off
