| | Re: GP2D12 & Expansion Board
|

You can cut the trace going to the pullup resistor corresponding to analog(0) on the main board and then all of the expansion board analog inputs will be floating. Analog(0) is multiplexed to provide all of the analog inputs on the expansion board. (...) (25 years ago, 10-Jan-00, to lugnet.robotics.handyboard)

Try placing a capacitor across +5V and ground. Get something in the range of 0.1 - 0.47 microfarads and just plug it into the headers on the HB. This solved my problems. -Scott Harris (...) (25 years ago, 10-Jan-00, to lugnet.robotics.handyboard)

Can I use the Lego ports on the Expansion board for the GP2D12? Do these ports have pull resistors and if so can they be disconnected so the pin float as required by the Sharp sensors? -Drew (25 years ago, 10-Jan-00, to lugnet.robotics.handyboard)

If you are not conversant in assembly, it will be difficult to obtain code for each individual digital port unless you get someone to write it for you specifically. However, if you switch to GP2D12 sensors, and remove the pullup resistors on the (...) (25 years ago, 10-Jan-00, to lugnet.robotics.handyboard)

I believe someone asked a similiar question to this but I didn't get an answer (I don't think). Question relating to the HB expansion board and servo control (or lack of same). I can control standard servos (S148, 3003 etc.) just fine, they run as (...) (25 years ago, 10-Jan-00, to lugnet.robotics.handyboard)

just to be clear, there are two types of LEGO sensor: active and passive: * passive -- touch sensor, temperature sensor. * active -- light sensor, rotation sensor (aka shaft encoder, angle sensor) without expansion board, the HB can only deal with (...)

The LEGO sensors and the RCX are the same thing. The standard Handy Board (without an expansion board) can handle all of the passive LEGO sensors such as the touch and rotation sensors. The expansion board is needed to use the active sensors such as (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)
