i m interfacing the stepper motor with 8051 i hav all circuitry ready but i want to know how to generate the required RPM for stepper motor EG: i want to run my motor at 60 RPM then what all calculations are required i hav taken a timer for the clock pulses but confused in the calculations do u hav any sample program for it i m using ic which has clocks pulse pin, i will be giving the clocks to that pin
i ve got the stupid email working now!!!!!!!!!!
send code very soon for me
pleas
i check my email and nothing there
send v soon for me
halop,
I just tried sending an email to you again. No success!
A little bit of advice for you - Get sufficient understanding of email configuration before embarking on motor simulators or anything else.
Sorry, but I really don't have the time (or patience) to continue with this.
i am wanting advise from a profesional poeple.

Am i the only perosn who works hard here? and give me the code
open letter To Webster and Oxford dictionary editors:
Please add to the definition of "working hard" "asking for the job done for free by someone else"
if you dontt give me help you dont ask me for help when you need it
Well, "halop relkarv" does actually seem to be working quite hard at avoiding doing this work!
I know I have to admit to using a pseudonym, but I do wonder if "halop relkarv" is a real name. How would it be pronounced?
I just ran it through an anagram service hoping to find a possible alternative or maybe a country of origin. The closest I got was "Hark Alp Lover" or (possibly) more suitable "Ark Valor Help".
The name is quite funny - I don't think I have ever heard a name that sounds so completely reversed without being reversed.

Don't you mean "kramretsew rep"...?
thank u all for the reply i m going through notes but i hav one doubt that if i want to generate an RPM say 70 then what all calculations should i make i m using full step motor 1.8 degee/step so to move one complete rotation 360/1.8=200 steps 70 RPM means 70 rotations = 60 sec so for 1sec = (70/60) = RPS and for 1 rotation = (60/70)sec but then how to calculate clocks from it and load it into the timer??
You have concluded 70/60 Rrevolutions/second. You have concluded 200 steps in a revolution. Obviously, you need 200*7/6 steps / second. If you have read the datasheet, you know if there is one, two or more clock pulses for each step of the motor. The documentation for your processor will then inform how you configure it to generate such a frequency.
There are examples in the C51 downloads section:

The operation of the standard 8051 timers is described so-called "bible" for the 8051:

Chapter 3 - 80C51 Family Hardware Description: www.nxp.com/.../80C51_FAM_HARDWARE_1.pdf
See the Data Sheet for your particular processor for any special features.

hello; i hav read the timers and the datasheet but for the clocks, i m asking regarding the rampup i.e. even if i want to attend the 100 RPM but i will start with 10RPm i.e. lower one in that case calculations are reqd and i m searching that for the one step how much clocks are reqd in the datasheet
i want to know how to calculate the time period reqd for the clock pin to toggle from 10RPM to 100RPM
