G'day, I am working on a robot for RoboCup Junior Soccer. THe table that the robots play on has a greyscale floor (ie it goes from white to black forming a...
I woued sugest an IR reflectance sensor, using a visible light reflectance can be confused by external lighting. from a fixed distance (say 5mm), the white to...
I'm offering a July discount on my Sumo11 boards at http://www.1sorc.com These boards mimic the Handyboard. -Dan BTW, I did consult with the site owner before...
Hello. Is there anyway to increase the sample rate of the analog ports to the handyboard? For example, how do i change the sampple rate of port E to be...
Your references are somewhat crossed. port E is a HC11 reference. the handyboard has circuitry to multiplex the hc11 ports over the base and expansion ports...
you'll have to do this in 68hc11 assembler. Interactive C's p-code is just not fast enough. You also have to remember that the handyboard's E clock only runs...

hello, I've checked almost all possibilities, and I still don't know why my battery won't charge. I've bought new adapter, and battery pack, but it didn't...
get a multimeter. check the current going in to the battery. if its less than about 5ma, its a problem with the charging circuitry. if its more, your batteries...
hi guys, i have modified my handy board so that i could run more power through it. I cut the track in the bottom left corner like it says on the HB site. Now i...
when u cut the trace was it on the HB or the expansion board? hopefully you cut the trace on the expansion board where it says. that should have no effect on...
Hey all, I am sitting here this morning, and reading over my daily HB group messages and it occured to me that I have been out of the HB game for a while, so I...
... HB group messages and it occured to me that I have been out of the HB game for a while, so I wanted to propose something to the group. I had an idea a...
James, I believe the stack size in IC 4.3 is 512 bytes. In general any persistent object, or ones you intend to share between functions need to be global. You...
When I needed mor Power on the normal HB outputs I used a trick of a friend of mine: I simply stacked another L293D on top of the one already sitting in the...
I have also thought about this, probably building some small simple robot, which has less sensors for sensing. This could be the plattform and everyone who is...
Hello, Please forgive me for my naivety on this issue... I'm a complete newbie to the Handy Board and am having difficulties getting up and running. I recently...
Okay, I've learned a fair amount since last night but was too tired to write again then... I came across Appendix A1 in Fred Martin's book which cleared up a...
The PCODE you speak of is the IC Operating System or "Firmware" that interprets IC (That is Interactive C now available from www.botball.org). I believe it is...
I believe both the IC pcode and the jbug11 monitor are attempting to live at the same memory locations. The messages are JBug11 attempting to defend itself....
Everytime I initialize an array I get an incorrect response for the last element in the array. Here's an example: int foo[]= {3, 7, 14, 21, 55, 32}; foo[0]=3 ...
I did just try this on IC 4.3, it appears to be a bug. There is a bug report site at http://www.botball.org/ic for the moment, set the last value in your array...
Hi all, The IC manual says that local and global vars that are not specifically initialized are initialized to zero, but when I try it with global floats in IC...
You are making an array of floats, I am not certain that classifies as "a global variable". a single float is initialized to 0.00 in my IC 4.301. the...
