 | | Maximum Subroutine numbers?
|
|
Does RoboLab have a maximum subroutine number? Also, what is the maximum number of subroutines which can be defined? Referring to real subroutines, not SubVIs. I have a program which defines 5 subroutines, numbered zero through 4. It seems like when (...) (22 years ago, 28-Dec-03, to lugnet.robotics.rcx.robolab)

| | What is "Stop Event Monitoring" for?

The Robolab manual says "This command stops the program from watching for events" and gives an example which is essentially identical to the example for the "Start Monitoring for an Event" icon except it adds a "Stop Event Monitoring" icon after the (...)

What exactly does the Robolab "Reset Event" icon do? Under what circumstances would or should it be used? The Robolab manual gives only a Microsoft-esque useless restatement of the name of the icon: "Event This command resets monitoring for an (...)

Just to verify the verdict... yes, it did work with w2kpro installed on this laptop. One note is that w2k vanilla does not support wireless 802.1g device, which is what comes with this toshiba satellite p25. It requires service pack 4. -- emabrey (22 years ago, 8-Dec-03, to lugnet.robotics.rcx.robolab)

Could someone explain to me technically why this sort of of problem with the rotation sensor occurs? I know how quadrature shaft encoders are _supposed_ to work, and I can't see why this sort of thing should happen in the first place. >> Mark (22 years ago, 30-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)
