 | | Smooth PWM routines for IC 3.1/3.2
|
|
Thanks to Julian Skidmore and Scott Seaton, we have a version of pcode and libraries for IC 3.1/3.2 which implement Julian's "smooth pwm" routines for the MIT Handyboard. To grab these, please go to the following address: (...) (26 years ago, 25-Apr-98, to lugnet.robotics.handyboard)

Hi For a relatively simple solution you may want to look at (URL) have connected and run steppers using this method. It does not get the best from the motors but it will let you experiment easily. (26 years ago, 24-Apr-98, to lugnet.robotics.handyboard)

Dear Jan-Sipke, Two-dimensional arrays are not implemented in the freeware IC 2.8 -- sorry. I just tested and your code works fine with IC 3.1/3.2. -- Randy ---...--- (...) (26 years ago, 24-Apr-98, to lugnet.robotics.handyboard)

I am planning on using stepper motors w/ a handy board and will be powering them separately from the rest of the board. What type of motor should I use? I have seen 6 and 12 volt motors availble, if anyone can recommend which to use I would (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

First I want everyone to know two things. First I am new to this list. Second, I have moderate knowledge of electronics.... Until about a few weeks ago, I had been working with Basic Stamps 1 and 2. After looking at all the information about (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

Hey, I just wanted to thank everybody for there help with this, it did turn out to be the pull up resistor problem, I feel like a moron. We used the handyboardy sonar interfacing schematic when we wired it up and failed to realize that we aren't (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

I was wondering if anyone out there could send me some very basic, easy to understand programs that could help me figure out how to use sonar modules. Thanks, Richard (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

Generally the capacitor is the problem :-) The capacitor in the original note is there to pull BINH true* to allow the sensor to detect things that are closer than 18". Generally, when you include it, unless the design of the system holding the (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)

(...) Are you using the "smooth" PWM motor routines? Note also, that a DC motor does not change velocity linearly with an increase in current unless it is under load. This was a recently asked question on the list. Maybe grepping the digest for (...) (26 years ago, 23-Apr-98, to lugnet.robotics.handyboard)
