Buttons without Scheduler

make a class that implements Sendable

and put in this data somewhere

    public String getSmartDashboardType(){
        return "Button";
    }
    private ITable table;
    public void initTable(ITable table){
        this.table = table;
        if(table!=null){
            table.putBoolean("pressed" false);
        }
    }
    
    /**
     * {@inheritDoc}
     */
    public ITable getTable(){
        return table;
    }

to check if the button is currently pressed on the dashboard, just use

table.getBoolean("pressed");

(not 100% sure about this but thats how Trigger does it)

e/ No. send it to the dashboard via

SmartDashboard.putData(yourButton)

than get it via

SmartDashboard.getData(yourButton
