Michael- I seem to recall something about LNP not being completely thread safe. However, there is no documentation on that at all.

Haven't heard of anything. Sorry about that. Then again, I run Linux for a reason- it isn't possible for a program to do that to me.

No. There isn't any. You cannot control the camera form NQC or the RCX for that matter. You can respond to the messages that the Camera sends to the brick via Message().

Not exactly.... The output is an analog voltage, meaning it's not exactly a digital TTL 0 volts or 5 volts, but ranges from 200mv (call this low) to Vcc-200mv (call this high). But this is a PWM output, meaning that with the chip stationary with (...) (24 years ago, 16-Oct-00, to lugnet.robotics.rcx, lugnet.robotics)

From looking at the data sheets, it's going to be a bit more of a project than just "hooking it up". At a minimum you'll need to have a small micro to decode the dual PWM outputs, and they (AD) have a data sheet describing the use of a Parallax (...)
