Hi I've a Polaroid Sonar Ranging Modul. The longest distance I can mesaure is about 2,7 meters. In my opinion it's not the hardware, but as the result is an integer, so it can't be greater than 32768. Right? Has anybody developed another programm, (...)

Hi, I have connected sonar to my HB and it is time to analyse the data. Is it true that the sonar range reading is in a cone shape at 30 deg. and not at point form ? I just can't find any information from the Polaroid home page. Is anyone there (...) (24 years ago, 26-Mar-00, to lugnet.robotics.handyboard)

Ive used the serial routines on the Hb site with moderate success. You can send data byte by byte along the line through the interface board and back to your serial port. A simple way to test the incoming data is to run a terminal program on the (...) (24 years ago, 24-Mar-00, to lugnet.robotics.handyboard)

(...) I've done this. Kind of. I hooked up a Handyboard to listen to a GPS, and to send commands and data to a terminal node controller (an amateur radio modem) to send my position out over the radio. In order to do this, I told Interactive-C to (...) (24 years ago, 24-Mar-00, to lugnet.robotics.handyboard)

Has anyone out there ever uploaded data collected by the Handyboard back to the PC? I need to get some distances measured by our sonar sensors back up to the PC for use in another application. If you can help me, I'd really apprieciate it. (24 years ago, 24-Mar-00, to lugnet.robotics.handyboard)

Hi again, Don't be confused la. I think you had made a little mistake. In order to interface SSC with HB, the serial connection is not by the telephone line. The connections is done by connecting the serial data pin on the SSC. Remind you that it is (...) (24 years ago, 24-Mar-00, to lugnet.robotics.handyboard)

basically, yes. the inputs from the expansion board feed into the inputs on the main board. if you need a high impedance input, your best bet is to cut a trace on the main board and use one of those inputs. the exp bd takes over main board inputs 0 (...)
