Servo control woes

[sayzer]

For Acetronics,

This is not the place for your egoistic posts.

Why don’t you go to a primary school and show the little kids how much you know about everything you think you know about?

You can top your ego that way.

Sayzer,

If you want to know, I do not do care about my EGO ... no time for that.

I'd just like you NOT to tell wrong things to those who do not know ...

It's difficult enough to learn pic's programming ... try not to add your own errors nor misunderstandings ... verify first !!!

Ok, Acetronics I agree . People make mistake even the ones with 30yrs of experiences.

Could you pls tell us what happens if we send 250mS - 300mS pulse to an R/C servo at 50Hz?

Also, 350mS and 400mS at the same freq?

How would servo respond to these pulse(s) ?

Pls do not make it so complicated so that we, the learners without 30 yrs of experiences, can learn something from your valuable words. Before you post your answer, make sure that your answer does not conflict with your previous posts;

Hi, sayzer

So, you've decided to be frankly ridiculous ... your problem !!!

250ms pulses @ 50 HZ gives .... a firm "1" ( or "0" ) level !!! you've just recreated the resettable monostable mutivibrator !!!

Who should go back to primary school ??? ( period = 1 / frequency ... no need a highschool for that )

your servo wil just have the little "jump" for amplifier settling at power up ... and won't move any more.

you shouldn't have tried .... you're really boring.

Finally you got it Acetronics,

That is what I have been saying.

If you look at the original loop, below, the code is sending pulses from 200mS to 400mS. In this case, the R/C servo would goto extreme edge and stop there at its max input pulse (let say 240mS). However, the code keeps sending larger pulses upto 400mS even though the R/C servo already stopped at 240mS.

-----Orginal code-----

loop:

for i = 200 to 400 'When i=240, servo stops, but loop keeps increasing the pulse.
low servo
pulsout servo,i
pause 18
next i

goto loop

---------------------


An engineer like you, age 49, should be in teaching mode rather then an egoistic mode. You should be using more explicit words to express your knowledge and have others understand what you are trying to say rather then using complicated engineering terms (an expression of egoistic unsatisfactory career to show others how much you know and others don’t)

I will stop here. This is going nowhere.
Let stop here Acetronics; it has no benefit to any of us.

Eris's pulses are NOT 200 to 400 ms, as you tell,

but 200 to 400 x 5µS !!! this EQUALS 1 to 2 ms ...

read your manual more carefully before hoping to give lessons ...


Straight back to primary school !!!

Hope not to read you any more about that. CENSORED !!!

E.O.F.

Acetronics,

I would like to apologize for the things I said.

You were right and I was wrong. I missed some parts and behaved impolite.

I also sent you a private message to apologize.

Sayzer
