 | | Basic Stamp to Handy Board Interfacing
|

Hello, Has anyone ever interfaced the Stamp to the Handy Board. I am thinking about using the SPI port on the HB to do this. I truly appreciate any assistance. Guillermo (23 years ago, 11-Mar-01, to lugnet.robotics.handyboard)

Hey all: How fast does the HandyBoard with the standard interactive C libraries execute standard IC instructions? What about the software system interrupt at 1kHz and the multitasking overhead, how do they play into things? I know float instructions (...) (23 years ago, 10-Mar-01, to lugnet.robotics.handyboard)

In 1999 someone requested information on how to interface I2C and the Handyboard. I would like to revisit that request. Any information on components and code to use would be appreciated. Andrew P. Loy andyl@citlink.net aloy1@utk.edu (23 years ago, 9-Mar-01, to lugnet.robotics.handyboard)

Yes, it can be used to control a drill motor, but probably not directly. It can drive 9V motors at 1 AMP (i think, depending on which h-bridge chips you have). I'm sure a drill motor will draw more than 1 amp, so you will need to use external power (...) (23 years ago, 7-Mar-01, to lugnet.robotics.handyboard)

Hi, All. I'm new to the list, but I was wondering if the handy board could be used to control something like a 7.2V cordless drill that you could get from Home depot? (23 years ago, 7-Mar-01, to lugnet.robotics.handyboard)

Hi All, This problem has been addressed many times before, but I have yet to find a solution. I have come accross a handyboard that has been sitting around for a while, and I decided to refresh its internal program. To do this I have tried all of (...)

"It's a primitive" means that it's defined in the machine code, in the runtime engine. You can look through the source to pcode.asm to see how stuff works... (URL) . Fred In your message you said: (...) (23 years ago, 28-Feb-01, to lugnet.robotics.handyboard)

I'm trying to locate the actual code that comprises mseconds(), but all I can find is a statement saying that mseconds is now an IC primitive. Is there anyway someone can direct me to that code? Thanks in advance (23 years ago, 28-Feb-01, to lugnet.robotics.handyboard)

Rob, a few Q's: 1. Can you verify that +9v is being applied to the sensor by transistor Q2. Measure the voltage at the collector, you should see a pulsed waveform (rectangular wave) with +9v on's and 0v off's. (Refer to (URL) What is the (...)

This is a follow up to my original question about the rotation sensor. When we hooked the sensor up to the oscilloscpe and the Handy Board, we could see the voltage transitions on the scope.

There aren't user-adjustable thresholds in my Exp Board LEGO rotation sensor code. Rob, could it be that you are spinning the sensor too fast?
