# Joos + FTC Dashboard (=🔥)

The biggest change from just FTC Dashboard to Joos is changing all @Config to @JoosConfig. What's the difference?

First-class Kotlin support. No more @JvmStatic and support for top-level properties.
Works on individual variables, so not all static variables are editable.
Works on immutable variables.
Supports immutable Kotlin data classes via @Immutable.
Supports custom config providers with @MutableConfigProvider and @ImmutableConfigProvider.

Here's an example of some of the differences:

@Config
class MyOpMode : OpMode {
    companion object {
        @JvmStatic //You need JvmStatic
        var myVariable = 1.0
        
        //Needs to be mutable
        var myPIDCoefficients = PIDCoefficients()
        
        //id isn't editable here
        var myData = MyDataClass(1)
    }
    
    data class MyDataClass(
        val id: Int
    )
}

@JoosConfig
class MyOpMode : OpMode {
    companion object {
        //No JvmStatic required!
        var myVariable = 1.0

        //Can be immutable!
        val myPIDCoefficients = PIDCoefficients()

        //id can be edited!
        @Immutable
        var myData = MyDataClass(1)
    }

    data class MyDataClass(
        val id: Int
    )
}

# SuperTelemetry

Ever had issues trying to use FTC Dashboard's MultipleTelemetry and the field overlay at the same time? SuperTelemetry solves all of them! It has all the functionality of MultipleTelemetry while giving you access to its field overlay and not requiring any setup! To use it, just replace telemetry with SuperTelemetry in your OpModes, or just telem if using CommandOpModes.
