in you controller 

$scope.yourValue="myValue";

in your directive 

app.directive('myDirective',function(){
 return {
        restrict: 'E',
        scope: {
            yourValue: '='
        },
})

in your dom 

<my-directive your-value="yourValue"></my-directive>

If you are not using isolated scope than you can access parent controller $scope.

you can also use $rootScope.

like

Controller :

app.controller("demoCtrl",function($scope,$rootScope){

   $rootScope.xyz = "test";
// call your directive , value will be accessible in directive
})

Directive : 

app.directive(...,function($rootScope){
 return   {
 // extra code omitted.

  // get your value here like
  // var abc =  $rootScope.xyz;

}
)
