i want it in C++,please

hi,
good evening
i have a project about stepper motor controlled by micro controller (89c51)
till know , we couldn't burn the programs because the language of program is assembly language(as they told us),so we you want you to give us an program with C++ or machine language
our machine should run at
1- run clock wise
2-run anticlockwise
3-increase /decrease RPM
4-increase /decrease revolutions
5-stop motor
6-change the mode
i hope you help us
my regards
info about contoller AT89C51.
 

i have same project with source basic code

Added after 1 minutes:

if you need i can post here

i have lost cd attached with mag i have to type whole code again may be tomorrow i can post here with hex code bye

Added after 5 minutes:

will this circuit suitable for you guys
 
In this Stepper motor control ..

ADC is connected to 8051 and variable voltage is INPUT to the ADC ..
ADC outupt of ADC is used to control the speed of the Stepper motor..


hope u get the ckt if u understand the program
#include<reg52.h>
#include<lcd.h>
#define ADCDATA P3

sbit INTR=P1^4;

void Step_Delay();

void main()
{
unsigned char i,j,Step[8]={0x01,0x02,0x04,0x08};
unsigned char Prev,Present,Adc_Value;
Prev=Present=0x00;
P2=0x0FF;
while(1)
{
INTR=0;
Delay_Us(40);
INTR=1;
Adc_Value=ADCDATA;
Prev=Present;
Present=Adc_Value;

if(Prev<Present)
for(j=0;j<50;j++)
for(i=0;i<8;i++)
{
P1=Step;
Step_Delay();
}
else
for(j=0;j<50;j++)
for(i=0;i<8;i++)
{
P1=Step[7-i];
Step_Delay();
}
}
}
void Step_Delay()
{
unsigned char i,j;
for(i=0;i<25;i++)
for(j=0;j<135;j++);
}
 
hiiiiiii mr. sant
can down load the picture again
to see it a whole
and the codes please
 

circuit is available here

The Stepper motor need to pulse low at the data pin (i used the stepper that used 4 pin data). and the Vcc have two pins. the procedure is like this...

1. to move right or left just follow the direction of the data pins
example :
to move right :

data1-----data2-----data3----data4
0 --------- 1 -------- 1 -------- 1----->(15 degree)
1 --------- 0 -------- 1 -------- 1----->(30 degree)
1 --------- 1 -------- 0 -------- 1----->(45 degree)


to move left:

data1-----data2-----data3----data4
1 --------- 1 --------- 1 ------- 0----->(15 degree)
1 --------- 1 --------- 0 ------- 1----->(30 degree)
1 --------- 0 --------- 1 ------- 1----->(45 degree)

and so on...

using assembly language, here some example

mov p1,#0ffh ; set the default value to 1

clr p1.0 ; 15 degree move to left

mov a, p1

rl a

mov p1,a ;move again 15 degree left

rl a

mov p1, a ; move again 15 degree left

thanks for you help
but one master told me ,if you want to burn programme inside the microcntroller
you have to write programme in hexfile (i think).
the problem now how i can write programme because unluky or Dr and Mr and Ms. they dont know
so you advice sir

the circuit that is above is incomplete i'll post may be tomorrow i have to search old magazine pls wait ok
 

also i want data sheet of drive circuit and and specifications of the stepper motor because i already bought one...


thanks for ur help
 

this might help you

specifications of our stepper motor
max rating voltage 5 v
max rated current per coil 0.5 amp
max rpm 20 for single and double coil excitation/ 60 in half step
torque 1.5 kg per cm2
step resolution 1,8 degree per pulse

but your stepper motor specification that you upload it
