I'm kind of new to IC and I don't know how to deal with all the errors yet. I wrote a simple code to record sensor inputs every 15 minutes. This is the code I wrote: void main() { while(1) { int x[]; int s=analog(0); int f=0; s=x[f]; sleep(900.0); (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)

(...) I wouldn't think so. I am looking in Kents documentation, and sure enough, there is something about putting a resistor on BINH. Also something about putting a cap in C7 on the ranging board. I'll play with things tonight. (...) Good thinking (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)

Tom, You mentioned that the INIT has the 330ohm. I'm pretty sure it's the BINH and NOT the INIT that should have the 330ohm. Reread Kents documentation. I don't think you would have damaged the unit in this short of time. Like I've mentioned on many (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)

Ahh... This sounds right from when I had the same problem. I just forgot about the disconnecting of the BINH. Mainly because it was accidental at the time. Anyways, the point I wish to make is that you have a bad ranging unit. This symptom is (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)

Thanks, I followed Chuck M's advice, and disconnected the BINH, and the thing words, with 23" as the minimum distance. (...) I would have to possibly agree. I noticed in your earlier mail you have suggested putting a 330 ohm resistor between INIT (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)

For those who are interested..... I have recently developed a way of signalling 4 sonars from the HB using a logical switching circuit controlled by one ranging board and another board developed to switch which transducer is being signalled by the (...)

Tom, I purchased 2 OEM kits (4 ranging units w/transducers) From this I had 3 bad ranging units. You'll notice a socketed chip on the PCB. I would suspect that this chip is suspect to failure. Anyways, in order to solve your problem, I would suggest (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)
