| | | | | Polaroid Sonar, etc
|
| 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)
| | | | | Pulse Accumulator
|
| 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 (...)

| | | | | Memory/Sampling Rate
|
| 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)
| | | | | Re: sonar sensors
|
| 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)

| (...) not easily. half of the lower 32k of the 6811 address space is consumed by the '138 circuit to generate 4 digital input and 4 digital output areas. it would be possible to have some kind of data memory area making use of the signals on the exp (...)

| | | | | RE: 2-phase servos
|
| Everytime I typed 'servo' in my original post I meant 'stepper'. I dont know what I was thinking... sorry. (28 years ago, 31-Jul-96, to lugnet.robotics.handyboard)
| | | | | RE: 2-phase servos
|
| 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)
| | | | | 2-phase servos
|
| I have two questions; The first is about a 2 phase, bipolar servo motor that I ordered from digikey. Since I have never used servos much before I was stumped when I recieved the motor and it had four wires coming out (Red, Blue, White, Orange) of (...)
