Hey Gary, Thank you so much for the wheels. They are grade "A", better than I expected! They arrived yesterday and unfortunately I have to head for Puerto-Rico tomorrow for about a weeks worth of work. I am also posting this in the newsgroup for the (...)

Hi! I just got my HB with the I/O-expansion card and the start-up was not as straightforward as I have thought. I don't know if this will help you but ... I'm using a Toshiba laptop with Win98 and found that in order to get the serial communication (...) (25 years ago, 30-Oct-99, to lugnet.robotics.handyboard)

|
|
Greg: You can run assembly from within Interactive C, so if IC isn't fast enough for you, you can build in something that is. However, IC will execute pretty quickly in terms of how fast steppers run, so it could be that IC will work for you as-is? (...) (25 years ago, 29-Oct-99, to lugnet.robotics.handyboard)

Igor: Sounds like you have two problems, with the LCD being a separate one from the sync errors. For communicating with the board via IC.exe, try changing your port settings to 9600/8 data/no parity/1 stop/Xon/Xoff/FIFO buffers enabled. I don't have (...)

I am hoping to control some stepper motors with the Handy Board; I will be wanting to control position vs time. Therefore I will be wanting to send out the step control waveforms at varying times (to modulate velocity). Can this be done from (...) (25 years ago, 29-Oct-99, to lugnet.robotics.handyboard)

Yes, you can upgrade your HB to 64K and then use Interactive C on it. After the reset HB operates in a 32KB mode that is compatible with the original HB memory mapping. Your C code, however, shouldn't use the PD5/SS pin on the HC11 as it s used to (...) (25 years ago, 28-Oct-99, to lugnet.robotics.handyboard)

| | Re: stalled motor detection

If a motor stalls, it draws a lot of current (compared to normal operation). You can measure that quite easilyusing dedicated chip, or by measuring the voltage over a small resistor in series with the motor: if more current is draw, the voltage drop (...)

Shaft encoders are hard to beat. If the wheels are commanded to turn and aren't, that's a good indication that something is screwy. Plus, if you're doing dead reckoning, you need them anyway so they are already there! Gary Livick (...) (25 years ago, 27-Oct-99, to lugnet.robotics.handyboard)
