  Servo libraries
 
Can any one help me out with problems downloading servo.icb.I'm using the shareware version of Ic and when I type load servo.icb the screen goes black and all of a sudden I'm back in Windows 95. Thank you, Joe Martin Email:joema@mpx.com.au (27 years ago, 25-Jul-97, to lugnet.robotics.handyboard)
 
  Re: 2nd line of display
 
Have you considered storing the first line as a string and the second line as a string too so you can "reprint" the first line with the same contents making it look like only the second line was updated? I've never done it before so this is just off (...) (27 years ago, 24-Jul-97, to lugnet.robotics.handyboard)

  Re: Which 68HC11x1xx
 
'a0 is an earlier and discontinued version of the 'a1. 'e1 has some different features than the 'a1 but is almost identical for HB purposes.

  Re: New list member
 
Regarding your problem with the jack on the serial line getting hot and melting (uh oh), I believe it is because the HB and Mini-SSC serial lines aren't quite compatable.

Jeff, I used a couple of the 10mV/deg Kelvin ones, with nothing more than the current load resistor, ie no amplification at all. For example, freezing point = zero celcius = 273 Kelvin = 2.73 volts.

  Re: Servo control using Miniboard slaved
 
Chuck: I agree with you; what I've done with the MiniSSC is to break the path into a set of linear segments with via points in joint space.

  Re: FW: Serial Communications.
 
Hi Fred: The Mini SSC does have a TTL-mode, but it needs inverted data i/o mode.

  Re: Servo control using Miniboard slaved to Handyboard.
 
Using the Miniboard as a servo slave is a good idea, perhaps even easier is to use a BOTBoard since the BOTBoard doesn't have any motor drivers hooked up to it (no PCB modification required.) Using the MiniSSC is "ok" but for controlling multiple, (...) (27 years ago, 21-Jul-97, to lugnet.robotics.handyboard)
