This is certainly a known defect in the input circuitry in the RCX. I know nothing about other kernels apart from the standard Lego one (via NQC) but the results of my examining the problem indicated that the ports are scanned in reverse order, 3 - (...)

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)

(...) Thanks for the heads up, Mark. What's broken? (I did seem to misspell a URL to the brickOS website.) I'm fixing that now. See anything else? Stephen -- stephen@debian.org stephmo@users.sourceforge.net (22 years ago, 29-Jul-02, to lugnet.robotics.rcx.legos)

I'm not sure who would be responsible for this but the legos website at sourceforge is broken. (URL) doesn't work. It looks some changes were underway for the brickOS name change. mark (22 years ago, 29-Jul-02, to lugnet.robotics.rcx.legos)

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)
