 | | Connecting 2 RCXs
|

The IR interface is one way to establish a "connection" via messages between 2 RCXs and it works fine if both of the RCXs will receive a message - directly or by multiple reflections within the room. However, it is a slow communication. My problem (...) (24 years ago, 19-Oct-00, to lugnet.robotics.rcx.nqc)

No. There isn't any. You cannot control the camera form NQC or the RCX for that matter. You can respond to the messages that the Camera sends to the brick via Message(). I hope this syntax is right.... until(Message)>0); switch(Message()) case 1: // (...) (24 years ago, 18-Oct-00, to lugnet.robotics.rcx.nqc)

Sorry, Dean - now I got your point. There is indeed no way to read the contents of the datalog. What about storing the data (e.g. for path information, maps, etc.) into an ARRAY instead of the datalog? With RIS2.0 and the latest NQC version you have (...)

To my mind, the datalog is a good feature, since it helps with debugging or adjusting sensors.
