 | | lego firmware multitasking?

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)

Hi! all, Thanks for the replies, now I can use one null-modem cable with 2 DB-adapters to construct the cable for the RCX communicatoin. But the cost is about US$5.5. If the shipping fees to HK were not so high, I would perfer to buy the default (...) (22 years ago, 25-Jul-02, to lugnet.robotics.rcx.java)

Is there a hardware difference between the RCX 1.0 and RCX 2.0 in regards to the IR? Or is the difference eliminated by firmware? Jude (22 years ago, 24-Jul-02, to lugnet.robotics.rcx)

The cable is wired as a null modem cable (see (URL) If that's what you have, then it should work. A couple of other questions: 1. When you try to download the firmware does the green light on the tower come on? 2. Have you set RCXTTY to the correct (...) (22 years ago, 24-Jul-02, to lugnet.robotics.rcx.java)

Hi, all! I've just bought and got a IR serial tower from bricklink but I haven't a default lego serial cable.

Richard, A little known fact is that if you "punctuate" a number with any of the following characters ,./-: you will get a double on the stack in the old FIG Forth. so 123-4567 will put the double value 1234567 on the stack.
