| | Upgrading RCX to 2.0

My first Mindstorms kit is the NXT but I have found some interesting projects for the previous generation RCX. My basic question is, is the upgrade from say a RCX 1.0 or 1.5 to 2.0 just a software update via your computer or is something that has to (...) (19 years ago, 3-Aug-06, to lugnet.robotics)

I tried to plot power levels vs angular speed (in rad/s) and discovered goooood linearity ( remember how non-linear was RCX PWM)? The PID loop is a great idea, and I suppose that PID parameters should be tweakable. In SDK or HDK ( don't remember (...) (19 years ago, 3-Aug-06, to lugnet.robotics, lugnet.robotics.nxt)
