 | | SPIRIT SetSensorMode "slope" parameter —Bob Miller
|
| | | Hi all- I've been writing an article about programming the RCX using Delphi and the SPIRIT OCX, to appear in MicroComputer Journal Magazine in my Delphi in the Laboratory series. I've written an example program, to be published with source code, (...) (26 years ago, 9-Dec-98, to lugnet.robotics)

I didn't bother to decode this function in detail since most of its functionality can be inferred from the (...) (26 years ago, 9-Dec-98, to lugnet.robotics)

| | | | | (...) Well, I don't have my RCX yet, but I'd hazard a guess that the slope parameter sets a hysteresis for the boolean. So: instead of the boolean value changing every time it passes the halfway point, it needs to actually be (slope) away from the (...) (26 years ago, 9-Dec-98, to lugnet.robotics)

| | | | | (...) It sounds like you understand the general idea of how the slope parameter works, although I don't think that a slope of 10 implies that the transition happens when the raw value changes by 10. For slopes in 1..31, I believe the raw value (...) (26 years ago, 9-Dec-98, to lugnet.robotics)

My understanding of "slope" is that it is the approximation of derivative of the function "raw value"= f(t), i.e. it is the value for df/dt. This means that if you set the slope to 10, (...)
