I really didn't have anything in mind other than the solution. How could you use the SPI port to communicate with the PIC? (...) (28 years ago, 9-Jan-97, to lugnet.robotics.handyboard)

(...) Are you referring to using the SPI port on the Handyboard, or simulating the SPI function via other ports? If you run the handyboard as a master, then the handyboard is responsible for providing the clock output used to capture the data by the (...) (28 years ago, 9-Jan-97, to lugnet.robotics.handyboard)

|

Has anyone interfaced the HB to a PIC chip or other microcontroller without using the primary serial lines? I am wondering if maybe there was an I2C or SPI implementation done somewhere using digital outs. (28 years ago, 9-Jan-97, to lugnet.robotics.handyboard)

Mar, I responded last night to your personal address and to be quite honest, I'm not sure if I sent it to the right address..so let me say again, in response to your question about what kind of IR sensors my design group and I plan on using--we (...)

Hello, I am a beginner in Robotics and have looked at the Handy Board, Miniboard, BotBoard, and Basic stamps. I have decided I think I like the HB. The only thing is I want to make a mobile robot or arm that has basic AI, maybe using Subsumption. I (...) (28 years ago, 8-Jan-97, to lugnet.robotics.handyboard)

Can anyone tell me if it's possible to run more than one servo off the Handy Board? My design group and I are building a robot that will perform an autonomous search routine. We're in the rough developement stage and really trying to pin down just (...) (28 years ago, 7-Jan-97, to lugnet.robotics.handyboard)

keith-- you might have fried the motor ground to logic ground connection. a couple of times in my lab using 6.270 boards people shorted motor high to logic ground, with the result being a vaporized trace between the two grounds (the inductor was not (...)

Yes it is probably the inductor. It acts as a fuse in many situations. You are lucky -- it could have been much worse. -Fred In your message you said: (...) (28 years ago, 7-Jan-97, to lugnet.robotics.handyboard)

Hello, I have a clock signal of 5 kHz and an analog signal. (There are in total 128 clock pulses) I need to read in the analog signal every time the clock signal is high. So I need to read the clock signal with at least 10 kHz. I tried this with IC, (...) (28 years ago, 7-Jan-97, to lugnet.robotics.handyboard)

Keith, We'd be happy to send you a new inductor to try out. Let us know how it works out. Best of luck! (...) - Prabal (28 years ago, 7-Jan-97, to lugnet.robotics.handyboard)
