(...) I too have done this, with both a Garmin GPS-II+ and a Garmin GPS-35PC. I have posted segments of the code necessary to do this to the Handyboard list before, so if you look through the archives and grep for "WE7U", you should find them. If (...)

Justin, Interfacing a GPS to the handyboard is straight forward. Most GPS receivers comply with the National Marine Electronics Association (NMEA) standards. They transmit their information in ASCII "sentences" which are framed by a $ at the (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)

| | DC motors vs. servo motors
|
|
The nature of the PWM (pulse width modulation) is entirely different for servo's vs. plain DC motors. For a DC motor, it has a two wire connection. All drive power is supplied over these two wires -- think of a light bulb. When you turn on a DC (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)

| | Re: motors

For servo, there is a certain threshold duty cycle (say 50%) of the PWM signal, where anything above this threshold will make it to run forward, and less will make it to run backward. So, you still need to apply the PWM even if the servo is not (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)

That did answer my question. I am not familiar with servo motors, I have only used plain DC motors. I am also familiar with PWM. I was just unable to determine if the same PWM signal that drives plain DC motors could also drive servo motors. From (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)
