please

please post more about your problem

i have two servos that i would like to control with PWM because i cant seem to get it right anyother way.

You like to be secretive, don't you? We can't guess your setup, you have to explain more.

If you are using Arduino, there is a library that uses Timer1 to generate PWM servo pulses. http://www.arduino.cc/playground/ComponentLib/Servotimetimer1

If you are using $50 robot there is this tutorial: http://mil.ufl.edu/~achamber/servoPWMfaq.html

i guess rox2007 is referring to his problem posted here:

yep, would really appreciate any help

how would i modify it for a hacked servo

this tutorial is helpful. it actually leads to this

http://mil.ufl.edu/~achamber/servoPWMwCodeVision.html

but the codevision i have, which is the new one does not look like what was described in that tutorial

how would i modify it for a hacked servo

A modified servo for continuous rotation is controlled exactly the same as a regular servo. If you send a pulse between 1 ms to 1.5 ms, the servo will rotate counterclockwise at a different speed, the 1.5 ms pulse makes the servo stop and a pulse between 1.5 ms and 2 ms will make the servo rotate clockwise at a different speed. It all depends on servo quality. Some servos just rotate at the maximum speed no matter what pulse you give.

sorry i didnt say this earlier, but it worked...
thanks alot for the link. to use it with an atmega 168 you need the file incompato.h, i found it on google.
