Dirk, I don't know enough about the SPI to help, But I would like to know how it works out for you.. I am trying to learn s much about my Handy-Board as I can. I recently figured out the Addresses for the handy board, and I found that the Digital IO (...) (28 years ago, 16-Jun-96, to lugnet.robotics.handyboard)

Hi all, I am trying to have the handy board communicate with a miniboard. I found that using peeks and pokes at the SPI port takes about 500 cycles to do a single read char, so I tried writing the communication software in assembly. In this case, (...)

I've found the Hall Effect switches that All Electronics sells to be quite useful. Their part number is the HESW-2 and they are 75 cents each, or 10 for $6.50. (100 for $60.00). They are easily activated by the micro magnets that Radio Shack sells (...) (28 years ago, 15-Jun-96, to lugnet.robotics.handyboard)

Hi Ya, I'm looking at the Digi-Key catalog (also availible at (URL) and they have several flavors of rotary encoders from $3.38 (24 pulses/360 degree mechanical encoder) to $41.20 (128 pulses/360 degree optical encoder) with the cheapest optical (...)

Does anyone know where I can get the definitions of the virtual machine and bytecodes used by Interactive C? I am thinking of creating a smalltalk-like language for the Handyboard. Any pointers you can provide will be greatly appreciated. Jun (...) (28 years ago, 15-Jun-96, to lugnet.robotics.handyboard)

Hi all, I want to but the handyboard to control a walking robot. The walking robot needs 6 motors and these cannot be servos. I think about using stepper motors. But the handyboard is only capable of driving four. So do I need the expansion board as (...) (28 years ago, 14-Jun-96, to lugnet.robotics.handyboard)

|

I'd love to use the Handyboard buzzer to repeat a short warning on my mobile robot. Has anyone developed a program which can convert a WIN95 sound file (e.g., .WAV), or ANY sound file, into the proper IC tone commands? I'm so lazy I haven't even (...)

There is a wiring diagram for a typical Hall Effect sensor included in the sensors/motors notes on the web site. -F (28 years ago, 11-Jun-96, to lugnet.robotics.handyboard)

I'm trying to stick a shaft encoder on one of the wheels of my robot. In a search for the best way to do this, my current idea is to use a hall effect sensor, as has been recommended to me in the past. I've got a couple questions... First, where (...)
