 | | Define Event icon... —Elizabeth Mabrey
|
| | | Hi I'd like to set up an event to watch for a containers value = 3. I am trying to use the "Define Event" icon, but has no luck yet. Just wonder if there is anyone out there has suggestion. The official doc does not explain much different from what (...) (20 years ago, 2-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)

| | | | | (...) Elizabeth, you are a few steps ahead of me in working with 'Events'. Could you explain, in plain English, what exactly an 'Event' is? ...it's not a 'State' because it can be a constant or a variable. Yet you can have an 'Event Fork' which is (...)

| | | | | | (...) Hi Jerry, Event Handling can be a long chapter to talk about. I am sure you will find a more well-explained chapter in some OS or just language book such as C++, or even in Java. Briefly speaking, event is a piece of real time information, (...) (20 years ago, 3-Jan-05, to lugnet.robotics.rcx.robolab)

Set the upper threshold to 4, the lower to 2, and the duration (...) (20 years ago, 2-Jan-05, to lugnet.robotics.rcx.robolab)

| | | | | | Formula container? —Elizabeth Mabrey
|
| | | | I am trying to compare the light value of two sensors, namely s1, & s2 . I don't want to go through the long route which is to save the light values from different sensors to different container, then, compare them. How about using "formula (...)
