Hi everyone, I am having real difficulty at the moment getting anywhere with brickos. But it seems i do not have the kernel legos.srec or brickos.srec whichever it might be, it's just not there. I think maybe it is because "make depend" command (...) (22 years ago, 26-Jan-03, to lugnet.robotics.rcx.legos)

The Lego firmware cuts power for about 200uS, with a period of 3mS. So most sensors have to have enough capacitor based power storage for the full 200uS and be able to run on about 93% duty cycle. (The rotation sensor is one of the devices on the (...) (22 years ago, 19-Jan-03, to lugnet.robotics.rcx.legos)

With the scheme I mentioned, power would be cut to only one sensor for ~25us. The sample (...) (22 years ago, 19-Jan-03, to lugnet.robotics.rcx.legos)

Nick, What you propose it's another way, and of course, should work, but we might have to create another software layer over the current operating system of the RCX (of course, legOS), and we would loose 1 sensor per RCX.
