		Interesting BrickOS Timing Results
Hi All, The recent posts about interfacing an i2c device to an RCX sensor port (in .robotics) got me interested in looking at the kernel code that handles the sensors. So, I did and found myself looking at the ds_handler function. This function is (...) (22 years ago, 14-Jan-03, to lugnet.robotics.rcx.legos)

Can I have the computer read the datalog after a program is finished, and then, depending on what the datalog reads, have it download a different program to the RCX?

Hi Mr Soh, Thank you very much for your input. Would you share your experience and views regarding tackling roboball with the LEGO RCX and light sensors, without other soldering electronic components.

		RE: H8/300 Assembler/C interface

		Re: Powered Sensors
Ok, I have gotten myself confused again. 0-0.32mA represents a voltage dropbetween 0 - 3.2 volts. Therefore the voltage that the RCX "reads" on theA2D is between 5 - 1.8 volts (1023 - 368 RAW)? To get a reading of 0 (RAW)it seems as though you would (...) (22 years ago, 8-May-02, to lugnet.robotics.rcx.legos)

		Re: multiplexor and legOS
