Update: Things have been really slow so far. I've added the two functions that I've gotten off the list to the archive. I'll be entering code fragments from "Mobile Robots" later in the week. If there are other books out there with IC or easily (...) (25 years ago, 2-Aug-99, to lugnet.robotics.handyboard)

This really isnt a HB question but >>>> Have been reading a few vision books , thay all have formaulas and examples etc but none of them help you with actual code , my actual question is does any one have some example vision code in C or anything?

| | Noise on the handy board
|
|
Fred and handyboard experts, I have assembled two handyboards and I am now helping 15 other people build theirs at San Jose State University. I found a problem on the first two I build that I belive causes the Sharp GP2D02 not to work. The school (...) (25 years ago, 31-Jul-99, to lugnet.robotics.handyboard)

| | Re: Millisecond timing
|

(...) See the Polaroid sonar code (from the HB web site) for an example of how to measure timing signals on the TIC3 channel. You initialize with: bit_set( 0x1009, 0x30 ); /* ddrd */ bit_set( 0x1021, 1 ); /* at tctl2, */ bit_clear( 0x1021, 2 ); /* (...) (25 years ago, 30-Jul-99, to lugnet.robotics.handyboard)

| | Re: Millisecond timing
|

The clock speed on the Handy Board runs at 2 Mhz, which is plenty fast enough for most things IF you run the right code. IC, used in its C implementation is too slow to catch anything at 1 ms reliably. However, there are a few simple work arounds. (...) (25 years ago, 30-Jul-99, to lugnet.robotics.handyboard)

| | Millisecond timing
|
|
I recently bought a Handy Board to use in acquiring time measurements varying by one millisecond. The Handy Board has a clock speed of 2kHz, therefore it should be able to measure down to one half millisecond. What I have found however is that the (...)

After assembling my own handyboard (ugh), and everything was (supposedly) solded OK, i tried to put the handyboard in bootstrap mode. But i get no results... i tested the stop button and it works fine (i compared with the OTHER handyboard i had)... (...) (25 years ago, 30-Jul-99, to lugnet.robotics.handyboard)

(...) Antistatic bags are conductive, right? You might have shorted the power to the ground via the bag itself, thereby killing your battery. Once a NiCad cell shorts, then it will can a large amount of current from a charger, possibly killing off a (...) (25 years ago, 29-Jul-99, to lugnet.robotics.handyboard)

| | Dead handyboard?
|

My hb was working fine, I took it on a trip in an antistatic bag. When I took it out of the bag, the battery was completely drained. But as soon as I started to charge it, one of the resistors burned up. So I tried charging it via the interface (...) (25 years ago, 29-Jul-99, to lugnet.robotics.handyboard)
