I'm not sure I follow you here. If you're talking about switching inputs using an output (lower the 'speed' of port A to change the relay controlling the input for port 1) well, then Yes, it can be done. However, the problem suggested below comes (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

could not the voltage level deside what relays should be turned on for instance on port 1? Now it might go wrong if the battery turns to be bad. ----- Original Message ----- From: "Steve Hassenplug" <hassenplug@mail.com> To: (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

My major problem was having a light sensor on each RCX that could change at almost exactly the same time as the other. Each RCX would then send a message to the other (for different reasons) The messages have to be sent ASAP, so one second polling (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

This is an interesting aspect of using two RCXs. My only experience is with NQC and the single byte "Message" function, but I have succeeded in making the communication link bi-directional and reliable. I simply create a process in the "master RCX" (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

I've been working on just such a robot. (two RCXs, two rotation sensors, four light sensors, and two touch sensors) Currently, my biggest problem has been communicating between RCXs. I keep getting collisions with my messages. I've had to limit the (...) (23 years ago, 5-Jul-02, to lugnet.robotics)
