how to change servo motor PWM

[Acetronics2]

Hi Alain,
I would be happy if I could just make interrupts work.

Could you PM me more about what you want to do ???

Thank you for your ideal. Actually servo motor pulse width variance from 1ms to 2 ms. I want servo motor shaft slowly turning. So I want to change PWM.

Hi, Dboy

YOU know what you are doing ( or closer: trying to do ...)

WE do not know anything at all of you.


Here I'm wondering if you want to turm the servo arm slowly from a position to b position ... or if you want a continuous slow rotation of this arm ...

Solutions are not exactly ( way of speaking !!! lol ) the same ...

PLEASE

Explain what you want to do AS a FINAL GOAL ...

I want a continuous slow rotation of servo motor

I want a continuous slow rotation of servo motor

continuous slow rotation of a servo motor - Is this servo motor capable of continuous (like a clock) slow rotation? Most, if not all, R/C aircraft type servos have mechanical stops that won't allow them to rotate past a certain point. Unless you've modified a servo to do a slow rotation somehow (and I don't see that happening), this slow rotation isn't going to happen.

He could have one of these.

Not sure how it works...but I'm going to guess...
The servo's feedback pot is mechanically disconnected and locked into the 'center' position? Assume that this servo's center is 1.5ms. You give it a pulse of 1.6ms, it runs right at X speed. You give it a pulse of 1.7ms, it runs right at 2X speed. Same thing for the other direction? You give it a 1.4ms pulse, it runs left at X speed, pulse it at 1.3ms, and it runs left at 2X speed?
Therefore, the farther the input pulse is from 1.5ms, the faster it will travel in that particular direction?
