(...) Are you using the 'stock' Mindstorms software? There is an option in the setup for the RCX, where you can set the time-off to 'infinity'. I don't remember where it is in version 1.0, but in 2.0 it's in the same area where you download the (...) (22 years ago, 1-Aug-02, to lugnet.robotics.rcx)

I have a problem with the RCX ver 1.0. Recently our group, MichLTC, ran a RCX controlled trolley in a train show. The problem is that the RCX shuts down while the program is running. I believe this has to do with the idle shutdown feature of the (...) (22 years ago, 1-Aug-02, to lugnet.robotics.rcx)

(...) If you've ever worked with multi-port A/D converters on a micro, and scanned all of the inputs you've been bitten by this one. It's caused by two things, parasitic capacitance on the chip itself and leakage between the lines going to the A/D (...) (22 years ago, 1-Aug-02, to lugnet.robotics.rcx.java, lugnet.robotics.rcx)

A light sensor connected to port 2 can cause on output from port 1. To see this (if you are using lejos), download the View object and hook up a light sensor to port 2. On my RCX, the port 1 raw values fluctuate between about 1010 and 1019. A (...) (22 years ago, 1-Aug-02, to lugnet.robotics.rcx)

Since I bought my mindstorms in 1998 I've been primarily using LegOS rather then the standard firmware. Now I'm helping coach a class for kids and we are required to use the standard firmware and GUI programming. I've been having trouble (...) (22 years ago, 27-Jul-02, to lugnet.robotics.rcx)

Does anyone have any programs that would make for a cool demo of the mindstorms package for 8-14yr olds and their parents? Preferably that would work well with the basic roverbots and would involve communication amongst multiple robots. I was going (...)

(...) They all have a current run through them, and their resistance is then turned into a 10-bit number by the RCX's ADC. 0 = no resistance, 1023 = infinite resistance. Normally, this is a small current. However, for light sensors to have the LED (...) (22 years ago, 25-Jul-02, to lugnet.robotics.rcx)

Hello, I was wondering if anyone out there has information about the RCX sensors (touch, light) and how they communicate/interface with the RCX itself. Perhaps schematics. Many of the links out there right now do not work. Any help would be (...) (22 years ago, 25-Jul-02, to lugnet.robotics.rcx)
