Hello all! I've ordered the Polaroid OEM kit which should hopefully be in tommarow, and was wondering where i could find schematics for making it talk with the handy-board. I looked in the cherupahka/...../kent, which has some code, but no schems. (...) (28 years ago, 4-Aug-96, to lugnet.robotics.handyboard)

Hello!, Is there a way to access to pulse accumulator subsystem of the HC11 using interactive C? And if so are there connections for it (Port A7) on the Handy Board (besides connecting it right to the HC11)? I have a pulse train signal coming from (...)

Hello everyone! I was wondering if there is a simple way to get more RAM on the HandyBoard...like an addition 32K? or maybe 128K? ---...--- Other question is about the sampling rate of the digital ports on the handyboard... I am getting about 335 (...) (28 years ago, 1-Aug-96, to lugnet.robotics.handyboard)

Hi Sriram, To answer your question succinctly, yes you can use the sonar modules on the Handy Board without the expansion board. Infact, Kent Farnsworth has written up exactly how to do it with your existing HB. Instructions, code, etc. can be found (...) (28 years ago, 31-Jul-96, to lugnet.robotics.handyboard)

Two comments for Garth (and others doing this) #1) You have 2 phase, bipolar *STEPPER* motors, not "servo" motors. The difference is quite significant if you were expecting a servo motor. A stepper motor has a coils positioned around the motor shaft (...) (28 years ago, 31-Jul-96, to lugnet.robotics.handyboard)

The limits on available user ram will make this difficult at best. If you can assume a 4K byte buffer for your image, that is only 64 pixels on a side, not much to work with. There are a couple of possible solutions however. One is the "ImageWise" (...) (28 years ago, 27-Jul-96, to lugnet.robotics.handyboard)
