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)

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 (...)
