Hi Guys,

I am hoping someone can help me. I am trying to use hservotime on my ARC32 however it just seems to return zero when I call it. To try it out I have the following code which was pretty much lifted from the ARC32 datasheet.



I seem to get stuck in the loop as stoptime = 0. The first hserout prints the following continuously...



So am I doing something wrong and if so what?

I am using Basic Micro Studio 2.0.0.8 although this was the same with 2.0.0.7

Any help would be much appreciated.

Thanks

I think I heard awhile ago that maybe just using HSERVOTIME may not properly startup the hservo system. Could be wrong.

Also I think EnableHservo2 is not needed or used anymore.


Maybe try something like: hservo [0/-30000] and see if that gets it rolling...

Hi Kurt,

Your a genuis.

That sorted it right out.

Thanks

Just so future people know, the correct method of using hservotime requires atleast one hservo command is used. If you don't want any servos running but you want to use hservotime you can use a no move hservo command like this:

hservo [p0]\-31000]

The -31000 tells it to stop moving the servo(P0 in this case). Since the servo wasn't moving it doesn't do anything to P0.

The hservo command has to be run once in order to use any of the hservo functions, even if you aren't actually driving any servos. This is because back in version 2.0.0.5 we removed the ENABLEHSERVO directive and now use the hservo command to tell the compiler it needs to include the hservo backend.
