    Here is the code for controlling stepper motor...Hope u can compile it in Linux 9 (2.4 ker)
    /* Stepper.c */
    #include /* for printf() */
    #include /* for ioperm() */
    #include /* for usleep() */

    #include "port.h"

    #define PORT 0x378
    #define TIME 1000

    void clockwise(){
    int i;
    /* i've got one rotor cycle in 12 loops */
    for (i=0; i<12; i++){
    port_out(PORT, 0x01); /* 0001 */
    usleep(TIME);
    port_out(PORT, 0x03); /* 0011 */
    usleep(TIME);
    port_out(PORT, 0x02); /* 0010 */
    usleep(TIME);
    port_out(PORT, 0x06); /* 0110 */
    usleep(TIME);
    port_out(PORT, 0x04); /* 0100 */
    usleep(TIME);
    port_out(PORT, 0x0c); /* 1100 */
    usleep(TIME);
    port_out(PORT, 0x08); /* 1000 */
    usleep(TIME);
    port_out(PORT, 0x09); /* 1001 */
    usleep(TIME);
    }
    }

    void counter_clockwise(){
    int i;
    for (i=0; i<12; i++){
    port_out(PORT, 0x08); /* 1000 */
    usleep(TIME);
    port_out(PORT, 0x0c); /* 1100 */
    usleep(TIME);
    port_out(PORT, 0x04); /* 0100 */
    usleep(TIME);
    port_out(PORT, 0x06); /* 0110 */
    usleep(TIME);
    port_out(PORT, 0x02); /* 0010 */
    usleep(TIME);
    port_out(PORT, 0x03); /* 0011 */
    usleep(TIME);
    port_out(PORT, 0x01); /* 0001 */
    usleep(TIME);
    port_out(PORT, 0x09); /* 1001 */
    usleep(TIME);
    }
    }


    int main(){
    int i;
    if (ioperm(PORT, 1, 1) == -1)
    printf("There's something wrong...
    ");


    for (i=0; i<30; i++)
    clockwise();

    return 0;
    }


    /* port.h */

    #ifndef PORT_H
    #define PORT_H

    static inline int port_in( int port )
    {
    unsigned char value;
    __asm__ volatile ("inb %1,%0"
    : "=a" (value)
    : "d" ((unsigned short)port));
    return value;
    }

    static inline void port_out( unsigned short int port, unsigned char val ){
    __asm__ volatile (
    "outb %0,%1
    "
    :
    : "a" (val), "d" (port)
    );
    }

    #endif

    Hi,
    Sumit I want help in program of controlling stepper motor in 'C' language, Actually I am doing 1 embedded systrm project in which i have to run the motor from pulses can you tell me How can i program? And the motor is 5 wire unipolar.
