| Does anyone know the impedance onto the sensor inputs on the HB and/or any suggestions for setting them to receive signals sent at 220K Ohm. Joe Martin joema@mpx.com.au (26 years ago, 10-Jun-98, to lugnet.robotics.handyboard)

| (...) Hmmmmmm.. as I recall, there are 47k pullups on those inputs. These are used to condition the signals when used as a digital input. The 'HC11 pink book suggests that any input resistance of greater then 10K will "...degrade A/D accuracy." The (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)
