Motor control with PIC16f84A. Coding problem.

[Rose Palmer]

I need to control the speed of a stepper motor. I have the PIC16f84A microcontroller, MPLAB IDE v8.53,  HI-TECH C PRO v9.60PL3 compiler, and PICSTART Plus programmer. I have a driver for the motor as well. My motor and driver are here: http://catalog.orientalmotor.com/item/stepping-motor-driver-packages-0-9-1-8-/-microstep-cmk-series-2-phase-microstepping-motors/cmk264apa-sg7-2?&plpver=11&origin=keyword&by=prod&filter=0.

I am struggling with the coding, as I am relatively new to it. The code that I have now is:

 

#include <htc.h>
#include <pic.h>
__CONFIG(WDTDIS);
double _XTAL_FREQ = 4000000;
unsigned long tdelay, * dvip = 5;    
unsigned long milleseconds, * ddvip;
void main(void)
    {
    TRISB = 0b00000000;
    TRISA = 0b11111;
    PORTB = 0b01000000;
    while(1)
    {
    milleseconds = tdelay;
    RB1=1;
    while(milleseconds > 0)
            {
            __delay_ms(1);
            milleseconds–;
            }
    RB1=0;
    milleseconds = tdelay;
    while(milleseconds > 0)
            {
            __delay_ms(1);
            milleseconds–;
            }
    }
return;
}

 

Am I headed in the right direction? Can you give me any suggestions as to why this isn’t working?

 

Thank You.
