Simple server

chillybasen

Hey guys,

I'm mainly a software guy, but I'm trying to connect the web server to a robot's servo.

I've been looking through threads and everything seems pretty advanced. I'm wondering if someone can point me in the right direction to do this:

1. Have spinneret running and accepting requests at http://myip/someurl/moveleft
2. By looking at the URL, do some magic that then makes the servo move

Any help would be amazing

Thanks

Okay, got this one running http://forums.parallax.com/showthread.php?127280-It-s-Alive!!...or-should-I-say...It-s-Online!!

Just followed the instructions on changing the mac, ip address and port -- works like a charm!

Now just to hook up to output pins -- any guides for that?

do you need help with making the servo move or do you have that?

The object exchange has several servo objects. You can look through there an find one that fits your project.

Consider using the Parallax Servo Controller. The PSC connects to the 3 pin serial I/O port on the Spinneret. The Spinneret controls up to 16 (or 2x16) from a single serial connection.

Thanks guys, will dig into the object exchange (didn't know about it)

I also saw that it's pretty easy to set a pin high or low with just:

DIRA[23] := 1
OUTA[23] := 1

Not sure the diff between dira and outa though

DIR is direction, it's used to set a pin (or pins) to an input or output.
OUT is the state of a pin, high or low.

See the Propeller manual for details and examples.
