Hi everyone,

Im working on a project with controlling a large Container Crane by 4 RCXs. I have implementet some controlling and a lot of functions in the model, including a userinterface made in Java for a laptop. The crane is controlled by a Joystick through the PC.

My problem is the communication speed from the PC to RCX, it takes about 0.5 sec before the IR tower sends the message (1 byte) to the RCX. I use the lejos software and the pcrcxcomm.jar and I use the RCXF7PORT for communication.

Are there any other method I can use which do not includes 0.5 waiting time, or do you know how to get around the problem?

Please visit my homepage to see the project, I have put a lot of pictures in there. http://www.gaasedal.dk

Best regards
