problem in driving the stepper motor in at89c51 in protius

[pratti]

my steper motor doesnot rotate 180 in protius.in protius it just stopt at -2.42.why is it so?my code is as below

hi
I think error in your programming

i have modified your code check it...

#include<reg52.h>
#include<stdio.h>

void T0delay();

void main()
{
int count;
count=0;
do
{
for(count=0;count<=48;count++)
{
P2=0x06; //0001
T0delay();
P2=0x03; //0100
T0delay();
P2=0x09; //0010
T0delay();
P2=0x0C; //1000
T0delay();
}
}while(1);
}


void T0delay() //delay by using timer
{

TMOD=0x01; // timer 0, mode 1
TL0=0x35; // load TL0
TH0=0x00; // load TH0
TR0=1; // turn on Timer0
while (TF0==0); // wait for TF0 to roll over
TR0=0; // turn off timer
TF0=0; // clear TF0
}

Can you attach your '.DSN' file . That is some what easier to solve your problem.

 

[pratti]

still it stops at -0.31 in protius?is there any change that i have to make in stepper motor in protius?

 

[pratti]

code is correct bt it is only rotating 7.5 degree in protius .how to continue this rotation till 360 degree?

 

[jayanth.devarayanadurga]

Why don't you post your Proteus file? What kind of motor are you using? Unipolar or Bipolar? Your code works only for Unipolar Stepper Motor.

Is your schematic like this

#include<reg52.h>
#include<stdio.h>

void T0delay();

void main()
{
unsigned int count;
count=0;
do
{
for(count=0;count<=48;count++)
{
P2=0x06; //0001
T0delay();
T0delay();
T0delay();
P2=0x03; //0100
T0delay();
T0delay();
T0delay();
P2=0x09; //0010
T0delay();
T0delay();T0delay();
P2=0x0c; //1000
T0delay();			T0delay();T0delay();

}
}while(1);
}


void T0delay() //delay by using timer
{

TMOD=0x01; // timer 0, mode 1
TL0=0x35; // load TL0
TH0=0x00; // load TH0
TR0=1; // turn on Timer0
while (TF0==0); // wait for TF0 to roll over
TR0=0; // turn off timer
TF0=0; // clear TF0
}

 

[pratti]

my protius file cant be uploaded,problem occurs.i am using l293d and bipolar motor and the motor is not rotating.i want to keep 1 minute delay.how could i do that?should i call the time delay function many times?

 

[jayanth.devarayanadurga]

Zip and upload. .dsn file cannot be uploaded without zipping. Have you configured P2 as output port by writing 0x00?

 

[pratti]

ya i write.bt i think i signal is not passing to the motor from l293d

 

[jayanth.devarayanadurga]

Nobody can help you unless you post your circuit. When you decide to post the circuit then ask further questions.

 

[aameer]

Yes Jayanth you are write...
