		Re: Motor Control Register (0xf000) and Memory Space 0xFDB0-0xFD7F
This note is of interest to people who build their own RCX firmware. It provides some additiional insight to the recent post concerning dual use of upper memory range and the motor control register. There's a trade-off between real time performance (...) (22 years ago, 1-Dec-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

		Re: decoding a message sent by an RCX
(...) Yes, you are correct - 11 bits total per byte. And yes, this is very non-standard. I believe the signal is inverted - meaning that IR light is present for "0" bits, and no light for "1" bits. But I'm going from memory here and haven't looked (...) (25 years ago, 4-Sep-99, to lugnet.robotics.rcx.nqc)

I've just upgraded to the kernel 2.4.9-31 and tried to compile this driver.

		controlling rcx with remote control
Hello, I'm new to this newsgroup but I need help with an issue... I'd like to control my rcx (with legos) with a tv remote control or likewise. I'm not a happy owner of the standard lego remote control and therefore I can not use the patch from (...) (22 years ago, 3-Nov-02, to lugnet.robotics.rcx.legos)

		Motor Control Register (0xf000)
Seeing as how there's been little traffic here recently, I thought I'd post about something I found that's cleared up a little mystery (for me at least). It concerns the RCX register that is used to control the motors. This register lives at 0xf000. (...) (22 years ago, 13-Nov-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

The idea is to pick a certain number of functions that will fit in the upper RAM space (~2900 bytes) and put these functions in a seperate linker section (other than the default ".text" section).

		Re: LEGO Mindstroms 2.0: Alternative transmission techniques

It is possible to include a PDA with Bluetooth or WiFi support as part of your robot, and communicate between the PC and the PDA over the RF protocol, and (...)

		Re: Wall wart for RCX 1.0
I use Radio Shack part number 273-1631. This has a selector switch which you should set to 9v for the RCX. The output from this particular transformer seems to be modestly stable, only rising to 10.5 volts or so off-load. This stays well within the (...) (22 years ago, 2-Nov-02, to lugnet.robotics.rcx)

		Re: Group project: RCX units run emergence simulation

In between you have any number of obstacles. The RCX's draw, or follow lines left by (...) (19 years ago, 24-May-05, to lugnet.events.brickfest, lugnet.robotics.rcx)
