+====== ROS2 Subscriber Analog Signal ======
-This block receives ROS messages of type ''std_msgs::Float64''. Each time the block is run by its time domain, the message content is written to the output of the block.
+This block receives ROS messages of type ''eeros_msgs::msg::AnalogSignal''. Each time the block is run by its time domain, the content of the last message is written to the signal output of the block.
 <code cpp>
-  RosSubscriberDouble subDouble("myNode/myTopic"); // create subscriber block
+  RosSubscriberAnalogSignal<> sub(node, "myNode/myTopic"); // create subscriber block
 </code>
-For ROS2 you have to pass the node, from where the topic is received. The ROS2 message is of type ''std_msgs::msg::Float64''.
+IMPORTANT The time stamp of the signal is set to the time stamp of the message.
+Alternatively, you could receive a vector by instantiating a block with
 <code cpp>
-  RosSubscriberDouble subDouble(node, "myNode/myTopic"); // create subscriber block
+  RosSubscriberAnalogSignal<Vector3> sub(node, "myTopic"); // create subscriber block
 </code>
-IMPORTANT The message is transmitted without time stamp. The time stamp of the signal is set to the actual time when running the block.
