moving servo

WRD5

I am trying to move a servo (Hitec HS-60) and have tried to use simple high low commands to make it move with no luck.
Do i need a command or a loop to keep sending pulses to the servo until it moves the necessary amount.
Am using BS2peMoBo with SB2pe Power-I/O-daughterboard

Start with the Basics, Baby Boy! "What's a Microcontroller", the best free download there is from Parallax. http://www.parallax.comhttp://forums.parallaxinc.com/dl/docs/books/edu/wamv2_2.pdf·

Meanwhile, here's some basic info on controlling servos. http://www.parallax.com/dl/docs/prod/motors/stdservo.pdf

Hey erco et al, there's a new version of WAM.

Certainly check out the downloads that Erco and W9GFO pointed you to.

As for servos, they are unique animals. Hobby servos require a repeating pulse that is 1ms to 2ms long. The pulse is approximate position of the servo so 1ms is completely turned one way and the 2.0ms long pulse is completely turned the other way. To center a servo the pulse is 1.5ms. These pulse must be repeated often. It has been a while since I worked with hobby servos, but I thought the minimum repeating pattern was 20 times a second. I suspect that the WAM e-book download will be helpful in showing you examples of how to control a servo.
