PULSOUT question?

nightrider

Why does the PULSOUT command use two millionths of a second as a value of measure instead of just one millionth?

example:
PULSOUT 13, 1 (2us)??

just curious...

thanks.

If you'll notice in the PBasic manual, each different speed Stamp model has a different value of measure for the PULSOUT. The underlying instructions that implement the PULSOUT statement are essentially the same in each different version of the PBasic interpreter, but take a different amount of time to execute depending on the internal speed of the processor involved. A number of other statements also are processor dependent in their timing including serial input/output (SERIN/SEROUT). The manual has tables showing these and there's now processor-dependent conditional compilation so that the same source program can be used on several different processors without changes.

I downloaded the pbasic manual pdf from the Parallax site.· I looked up the PULSOUT command and I see what you mean. It's taking my some time to gather all the tools that I need to build my robot army(jk). I guess I should have downloaded this manual from the start. In fact, I didn't know Parallax had all that documentation on its website.· Thanks for your help Mike.
