| | RE: Motion/Tilt Sensor from Analog Devices and the RCX
|
|
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 (...)

(...) Ok, thanks. I'll try everything else first, then try this if I get desperate. The main thing I hit a wall with was when I switched to floating-point, which increased my .lx filesize by about 2k, so if I go back to fixed-point, turn sound off (...)

Well, I've gone and run out of memory with my RCX. It manifested itself in a task that refused to run, presumably because the OS couldn't allocate enough memory for its stack. Took a while to track down and was annoying, but it was my own fault for (...) (24 years ago, 14-Oct-00, to lugnet.robotics.rcx.legos)

I've been doing a lot with LNP lately, and I have a few questions. First, the lnpd package I have says in the readme that there is a bug in the legOS kernel with sending LNP packets from multiple tasks. Accordingly, all of my LNP-sending functions (...)
