Hello, legOS 0.2.0 is out. If you like to program your Mindstorms in C, or if you would like to try, it has become better than ever.

Hi All, After a very frustrating weekend of fiddling with pbFORTH, I caved and asked Kekoa to help with a problem I was having with read_sensor() and pbFORTH. The problem we (mostly he) unearthed has to do with the SP and RCX firmware routines, so I (...) (25 years ago, 17-Oct-99, to lugnet.robotics, lugnet.robotics.rcx.legos, lugnet.robotics.rcx.pbforth)

Some sensors give raw values around 0x7000. #define CURRENT_STATE (raw<0x6fc0?STATE_0:...STATE_3))) (...) (25 years ago, 17-Oct-99, to lugnet.robotics.rcx.legos)
