Has anybody used an IR Control Freak with their handyboard as a means of guiding their robot around obstacles? http://www.robotmaker.co.uk/IRCF_L_V2.0.htm ...
Started to play with the Handyboard I bought from KISS. Handyboard analog ports 2-6 work as advertised (Reading of near 255 and goes to 1 when connected to...
This is not a problem, it is a feature. the analog ports 16 through 23 "float" that is they do not have a pull-up resister to force them highwhen disconnected....
Hi Jim, I re-soldered U2, U3 and the ceramic resonator, and that did the trick. Works fine, all is well. Next question: Is there support in IC 5 for the Lego...
Steve, If you have a copy of the legoexp.icb and specify #use "legoexp.icb" in your program, the lego sensors should work in the designated expansion ports. As...
Tried it with a Sharp IR Rangefinder. Values don't change as a 8.5x11 inch piece of paper is moved to and from the senrsor. Took a pot. One side to +5v, one...
Hi Jim, I just searched my hard drive and it isn't there. I used to have it when I had IC3 that came with the Handyboard Kit. Is there anywhere I can get it? ...
I am using the IR Control Freak to help guide my robot and it will send two numbers to the handyboard- one gives the direction of the object, and the other its...
Hi, I have some problems testing my CMUCam 2 with the CMUCam 2 GUI: 1. When grabbing the frame of a white sheet of paper, the picture looks slightly orange.In...
I have a question for the group. I have built two quadrature encoder circuits using the hammatsu p5575 chips. Each board has a +5V, Gnd, and two digital ...
you should use the quad encoder driver onthis board in the files section if you want to measure the direction of rotation of two shafts. the built in encoder...
The serial pins are in the RJ11 connector on the handyboard. the two outer wires are txd and rxd from the hc11, the inner are +5v and ground. the txd is...
there are several examples of music playing on the handyboard both in the IC library and in the files section of this board. What exactly do you mean by "a...
I have quadrature encoder software for 2 quadrature encoders. Is is an assembly file that has been compiled into an .icb file and it works on digital inputs 10...
Hi Jim, I got it up and running, but I modified the .asm file to use only two of the inputs, since that is all I needed. I then compiled it on Newton Lab's web...
be careful about using other sensors on those defined ports, if you look closely at the expansion board schematic, the signal line for lego sensors is switch...
Hi Jim, I wasn't planning to use the I/O on those other two ports, but thanks for reminding me anyway. Even though I wouldn't have used them anyway, it is good...
I have a number of handyboards that can't download firmware. All of these handyboards have the IR led (the one in the lower right-hand corner) lit. Does...
Hello, I believe some chips on your handyboards are burnt out, and thus causing this LED to lit due to no firmware inside. Have you tried to replace some chips...
Hello, Have you downloaded the apropriate Handyboard Expansion board files? You need these files in order to get the ports under Expansion board to work. ...
Further stuff. I did see that my 5 process are running. However, if I use any sleep(0.25); commands in a process, it seems that the function msleep() becomes...
Functions can call funcions. msleep is the actual delay processor, it tales a 32bit number of milli seconds to sleep. sleep takes a float number of seconds....
I'm a little late started on a robot that needs to go four feet find its balls either black or silver and return them home. All the while, avoiding the other...
... Thanks, I would be interested in seeing the code, but I dont know how to post to the files area either. You could send them to skfish@... if all...
