hello sir, i m doing a project related to speed control of dc motor in REAL time. i m using 89C51RD2 microcontroller and a dc motor of 12V. well i m not getting how to write the code of my program.i got some help from forums of keil.com i hav read the data base of RTX5i TINY OS from the MICROVISION2. please help me as soon as possible. thanking you, kulvinder.
In order to control speed you must, obviously, measure it
Or is it a stepper motor? If the micro is actually continuously causing the motion, it may not really need to measure it. (Precision or robustness might be good reasons to measure the actual speed of the motor anyway.)

if you need it "as soon as possible" then there are two possibilities a) do it yourself b) provide enough information to make it possible to provide answers.
