    hiii
    i am new with stepper motor .
    so i want some basic information related to timer used for stepper motor application in C.

    1)when the timer is overflow? and then what will be the next step.

    2) i saw some code ther is milli. and micro. delay function both are used WHY ?
    Here is the some code ... so plzzz explain me the follwing code bcause i want to be impliment like the same
    (IT IS FOR FULL STEPPING )
    void Milli_Delay(unsigned int ms)
    {
    while (ms--)
    Micro_Delay(100);
    }

    void MicroDelay(unsigned int us)
    {

    us += T1TC;
    while (T1TC < us);

    }
    WHAT IS THE TIMER CONCEPT BEHIND IT TO USED MILLI AND MICRO FUNCTION????
