(...) If you're using a custom motor driver in pbForth, why use the inverter circuit at all? Why not just generate the desired waveform directly? Is there not enough current to drive the servo that way? --Ben (26 years ago, 12-Feb-00, to lugnet.robotics, lugnet.robotics.rcx.pbforth, lugnet.robotics.rcx)

Hi again everyone! A few days ago I announced that I had developed a nice little circuit using easily available parts that would let you connect servos to the RCX - with no external batteries or microprocessors or anything! At that time, I said that (...) (26 years ago, 12-Feb-00, to lugnet.robotics, lugnet.robotics.rcx.pbforth, lugnet.robotics.rcx)

Here's the latest update. Hope we will get a clear picture of this #@$@ memory after all. The point is that the RCX processor can address 64k of memory, so let's divide this range into 4 equal area of 16k. (note:16k or 16384, in hex is 0x4000). (...)

I have seen some systems that have RAM set up this way: The first area is for the system, the second area is user programs and is allocated from the bottom up. The third area is user (and system) data, allocated from the top down. They "meet in the (...) (26 years ago, 10-Feb-00, to lugnet.robotics.rcx)
