| | | Joe I think proportional timeslicing would be a nice thing if the implementation would be efficient and straightforward. I don't consider my patch to be that. Would still be nice to see a snippet of your code. How do the other kernel developers feel (...) (22 years ago, 19-Jun-02, to lugnet.robotics.rcx.legos)

| | | | | Joel, I had planned on another post to provide a link to the code sample, but have run very short on time. I will try to get that up soon. I believe the sensor handling issue is a real issue. However, I have yet to see a simple solution that (...) (22 years ago, 19-Jun-02, to lugnet.robotics.rcx.legos)

| | | | | (...) Thanks for the link, your solution of proportional timeslicing is more straightforward than mine which I like. The only downside would be that a high prioritized process would have it's wakeup conditions checked less frequently than a low (...) (22 years ago, 10-Jul-02, to lugnet.robotics.rcx.legos)

The only difference between a low priority task and a high priority task is that the high priority task gets a larger time-slice when it is awake. This is not an (...)

| | | | | | | | I have been thinking (and toying with some ideas) concerning tthe wakeup checking. It might be possible to do wakeup checking more often then between each timeslice. This would make msleep more accurate and provide better sensor handling. I know (...) (22 years ago, 16-Jul-02, to lugnet.robotics.rcx.legos)

When the solver makes a step (for example forward) it uses the light sensor to search for a wall and the rotation sensor to measure the distance it has traveled. If a wall is hit, the solver steps back until it reaches (...) (22 years ago, 10-Jul-02, to lugnet.robotics.rcx.legos)
