sx/b vs stamp basic

Sawmiller · 2006-04-21 17:34

hi ppl,
i picked up a boebot hardware kit from ebay, and thought i would use a extra sx/52 proto board with a bread board for experiments.....
however i would like to see for the next sx/b rev a pulsout that has at least the resolution of the basic stamp... i mean here we have a faster, slimmed down proccessor than the stamp... and the stamps resolution is 2 uS sx/b's is 10 uS· quite a difference when your looking to , for example finetune the difference between the servo speeds...
anyways, anyone that has any hints , other than going to assembly.. ( i can, just dont want to

)

thanks for the great support

Dan,
SX/B pulsout resolution was set to 10uSec to allow byte variables (which up to now is all SX/B has) to control servos. So 0 to 255 generates 0 to 2.55 mSec pulses.

You can always just just do this:

 OUTPUT servoPin ' This only needs done once
 
 servoPin = 1 ' Faster than HIGH 
 pauseus pulseTime * pulseUnits ' One of the few place '*' is allows for parameters
 servoPin = 0 ' Faster than LOW

Bean.
