(...) I have started working on an expansion board version of the compass code. I won't have it done before fall probably (unless is snows or something really bad). I am involved in another huge project right now. My thoughts are to have the compass (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

Hi Doug: I built a 12-servomotor walking robot using two SSCs - their interface with the HandyBoard is well documented, and ICB drivers are available on the webpage. I communicate with two SSCs (www.seetron.com) via one serial line connected to PA7 (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

Hello, I am planning to build a robot based on the Lynxmotion Hexapod II and Big Grip kits. There will be 12 servos for lego control, 2 servos for the manipulator, and 2 more for a camera pan/tilt unit. Everything appears fairly straightforward, (...)

Hi everybody! I've been running both the Polaroid sonar sensor and Vector 2x digital compass on the HB without the expansion board. I'm using Kent Farnsworth's older sonar driver code that is designed for the motor driver output ports (U11). The (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

(...) I don't have the Ferrettronics chip datasheet in front of me but some off the cuff calculations: 2400 bps/10 bits per byte=240 bytes per second each servo will require at least 2 bytes (servo # and position) 16 servos * 2 = 32 bytes for each (...)

We just finished using the same comm. boards for our senior project, so maybe I can help a little. (...) One interesting phenomenon we noticed was that we received random noise at the receiver when the transmitter wasn't on. However, when the (...)

(...) I was doing some work on wireless between two boards using the DVP board. Though, I can't answer directly your problem coz you are using a computer as your other transceiver. So mine was a little bit easy, but maybe you can get something from (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

| | Re: Smooth PWM for IC3.2?
|
|
You misunderstood my point, or maybe I was not clear enough. I know the smooth PWM algorithm are available for I3.2. What I require is all the source code that's running on my handy board to be available. It's not the case for IC3.2, so I'm not (...) (25 years ago, 15-Apr-99, to lugnet.robotics.handyboard)
