(...) It seems like MacNQC can be used to download a new firmware on the RCX: (URL) you didn't, you should give it a try. I also had problems downloading firmwares to the RCX through the USB tower with many utilities. Only NQC did it right. Please (...) (20 years ago, 23-Jul-04, to lugnet.robotics.rcx)

Hi Andreas, (...) this is the pwoer supply for active sensors (light and rotation). It is interrupted briefly every 3ms to sample the value of the sensor. (...) It is done by the microcontroller, every 3ms the OCIA interrupt routine turns off the (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)

(...) Hi Andreas, Sensor inputs can be configured two ways: 1. Passive - sensor does not need power to operate 2. Active - sensor needs power to operate Active sensor ports put out aproximately 7V most of the time, and drop the voltage (every 3ms?) (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)

Hi, I'm interested in the electronical function of the three sensor inputs of the RCX. I took an osilloscope and measured the voltage of the ports. So I got to know that a rectangular signal is put on the sensor ports when they are activated by (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)

11 months ago, there was a thread in this newsgroup dealing with the implementation of BrickOS on Mac OS X. I was just wondering whether the situation had changed since then. I've downloaded M. Zapp's port of the GCC cross-compiler and tools, have (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)
