(...) The current LegOS model really hammers the sensors, almost to the point of oversampling them. It only takes a short while (less than 0.1 ms, I think) to sample all four sensors; I think LegOS samples the next sensor immediately after finishing (...)

When using firmdl to download a program to the RCX, what exactly do the numbers on the LCD indicate? Are there units I should be attaching to them, or are they just there to indicate progress without specific units? Just curious- Luis ###...### God (...)

John, I've been looking at your ping routine and note the following... Even if FF EMIT did not block, the wait makes things irrelevant. At 2400 baud, the FF is out the port within 4 msec. In fact, if EMIT did not block, you could probably wait jsut (...) (25 years ago, 13-May-99, to lugnet.robotics.rcx.pbforth)

No, it's not documentation for pbFORTH - yet. I have found a decent book on line, it is Tim Hendtlass's Real-Time FORTH book.

My DEFCON code multitasks OK (except when it tries to STOP). I doesn't actually work yet because it needs SendMessage (or non-blocking EMIT) but I'll post it here if anyone is interested (actually I'll post it unless anyone objects). (25 years ago, 12-May-99, to lugnet.robotics.rcx.pbforth)

John, You might want to try this little script to try out the tasker. It's based on Koh's demo. If you type TASK0 AWAKE and then .TASKS, you will see the chain is ok and that TASK0 is running. Now press the RUN button on the RCX and try .TASKS (...) (25 years ago, 12-May-99, to lugnet.robotics.rcx.pbforth)
