Hi Andrew,

"Andrew Meyer" <agmlego@gmail.com> writes:

However, I will state it (again) here. In one of the few
messages I did read during that time, I got the impression that
the NXT sensor ports were digital in nature.  However, my
thoughts followed this pattern:

*There are converter cables from RCX to NXT, mainly made for sensor use.
*RCX sensors are analog.
*Thus, either the NXT needs to have ADC's, or the cables themselves need to.
*If the cables had ADC's, though, then RCX motors wouldn't work with the
converter cables as they apparently do.
*Thus, I conclude that the NXT sensor ports must have ADC's behind them to an
extent, and thus homebrew sensors need not output a digital signal.

there are actually 3 I/O lines on each sensor port:
- 1 legacy sensor A/D with appropriate power supply on the same line.
- 2 digital I/O lines, one of which can also be configured as analog in.

The remaining lines are 2 GND pins and a power supply.


Cheers
Jürgen

While sitting in an incredibly boring IB Spanish I class this afternoon (no teacher=no work=no progress=boredom=idle thoughts), I had an idea. It may have been said already in the flood of NXT-based messages which crossed my inbox several months (...) (19 years ago, 18-May-06, to lugnet.robotics)
