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)

Sorry for my ignorance, but doesnt the datasheets mention that it contains both analog and digital outputs and either may be used. Ram (...) (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 (...)

Hi, I just order two free samples of Analog Devices ADXL202E at (URL) Anyone know if this can be hooked up to the RCX? Ram PS: Try to get a free subscription to "Sensors". It is a really cool magazine... (24 years ago, 15-Oct-00, to lugnet.robotics.rcx, lugnet.robotics)

(...) Well, I was thinking along the lines of having gcc optimize my program for space instead of speed. Of course, I'd be better off if *I* optimized for space instead of speed, but it can't hurt to have the compiler working for me, if it's (...) (24 years ago, 15-Oct-00, to lugnet.robotics.rcx.legos)
