how to draw the flow chart for the program sound generation using 8051 microcontroller

[Sana Paul]

hiii..I am doing a project based on how to generate sound using micrcontroller.Can u please help me to draw flow chart for this program??

 

 

// Program to generate different sounds using micro controller



#include<reg51.h>

sbit out=P1^0;  //output pin 1



void delay(unsigned char p,unsigned char q)

{

TMOD=0x01;  //timer0 mode1(16 bit)

TL0=q;      //load TL0

TH0=p;      //load TH0

TR0=1;   //turn on T0

while(TF0==0); // wait for flag generation

TR0=0;   // turn off T0

TF0=0;    // clear TF0

}



void play(unsigned char j,unsigned char k)

{

int i;

for(i=0;i<1000;i++)  //to play sound

{

out=1;

delay(j,k);

out=0;

delay(j,k);

}

}



void main()

{

int l;

while(1)

{

play(0xfc,0x66);  //playing sound of frequency of about 500 hertz with a delay between two frequencies

for(l=0;l<5;l++)

{

delay(0x00,0x00);  //delay of 71 miliseconds

}

play(0xfe,0x33);  //playing sound of frequency of about 1000 hertz with a delay between two frequencies

for(l=0;l<5;l++)

{

delay(0x00,0x00);

}

play(0xff,0xa3);  //playing sound of frequency of about 5000 hertz with a delay between two frequencies

for(l=0;l<5;l++)

{

delay(0x00,0x00);

}

play(0xff,0xd1);  //playing sound of frequency of about 10000 hertz with a delay between two frequencies

for(l=0;l<5;l++)

{

delay(0x00,0x00);

}

play(0xff,0xdc);  //playing sound of frequency of about 13000 hertz with a delay between two frequencies

for(l=0;l<5;l++)

{

delay(0x00,0x00);

}

play(0xff,0xcc);  //playing sound of frequency of about 9300 hertz with a delay between two frequencies

for(l=0;l<5;l++)

{

delay(0x00,0x00);

}

play(0xff,0xe8);  //playing sound of frequency of about 20000 hertz with a delay between two frequencies

for(l=0;l<5;l++)

{

delay(0x00,0x00);

}

}

}

Hi,

Microsoft office tool called ‘Visio’ is a good tool for drawing flow charts.

If you want to draw flowcharts i suggest you to use a flowchart software like http://Creately.com . If you are not drawing flowcharts frequently. I suggest you to use the web based version. Visio is bit expensive I dont think its affordable . So its better to use a visio alternative
