Hi Elizabeth, (...) there is an 8ms cycle, and the motor is on for a part of that: 1ms for power level 0, 2ms for power level 1, up to all the 8ms for power level 7. The rest of the time the motor is floating, i.e. the motor inputs are disconnected, (...) (20 years ago, 13-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

Hi I am curious how the power levels are being implemented. I am not talking about the icon level navigation. How the motor actually adjusts to the different levels setting? Gear slipping? Thanks in advance... -- Elizabeth (20 years ago, 13-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

(...) Not to put too fine a point on it, but RUN, PRGM and VIEW are read from an I/O port, while the ON/OFF button is tied to an interrupt line. That's what lets you wake the RCX up from a deep sleep, which you can't do with the other buttons. Ralph (20 years ago, 9-Feb-05, to lugnet.robotics.rcx)
