I was hoping, since the thread was already onto how to modify and mount the mouse guts, that it would have been preceeded by a successful attempt to interface the little beast. Since I already know quite a lot about how tedious it is to get data (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

That is correct each Task started has a higher priority and they all have a higher prority than task_swapper like Prio Task 1 -- Task Swapper 2 -- Motor Driver Task 3 -- Light Sensor Task 4 -- Touch Sensor I changed the all the priorities to 1 but I (...)

(...) Nothing yet. I have a guy in England that's trying to use pbForth to do I2C comms. As I see it, there are two possiblilities here. One is a bit-bang interface on a sensor input port. Tricky to do with pbForth because it allows the normal 1 (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

A Killough platform may have 3 motors, but it operates in a X-Y coordinate plane, not X-Y-Z. The camera is looking for pattern shifts horizontally or vertically, not radially within it's field of vision. As long as the axis of the spin is not (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

I'm no expert, but I can try to help you figure it out. Let's start with something simple. What version of LegOS are you using? How are you starting the 'task_swapper' task?
