| | | Hi Scott, there is lots of technical info available. The H8/3297 series hardware manual is probably what you're looking for: (URL) pdf version is available on the same site. More specifically, the microcontroller has 8 A/D input pins. Right now, (...) (26 years ago, 12-Dec-98, to lugnet.robotics)

| | | | (...) Nobody tried so far. The above is merely speculation - that's why I said "candidates". Should the pins turn out to be unused, legOS will support 6 A/D channels with minor changes. I have some software to work on right now, and I have a student (...) (26 years ago, 17-Dec-98, to lugnet.robotics)

They might, however, be tied to Vss or Vdd, so make sure you don't short anything out if do attempt to solder something to the extra (...) (26 years ago, 21-Dec-98, to lugnet.robotics)
