respected sir ,
when i try to convert program for this project it shows two error
1 syntax error
2 end missing error
plz sir help me
i want to make this project
program
#include<reg51.h>
sbit rs=P1^0; //register select pin
sbit rw=P1^1; //read/write pin
sbit e=P1^2; //enable pin
sbit quat=P3^0; //pin connected to quater level of tank
sbit half=P3^1; //pin connected to half level of tank
sbit quat_3=P3^2; //pin connected to three -fourth level of tank
sbit full=P3^3; //pin connected to full level of tank
sbit spkr_on=P3^4;
sbit spkr_off=P3^5; // pin to off speaker
void delay(int k) //delay function
{
int i,j;
for(i=0;i<k;i++)
for(j=0;j<1275;j++);
}
void write(int j) //write function
{
rs=1; //selecting command register
rw=0; //selecting to write
P2=j; //putting value on the pins
e=1; //strobe the enable pin
delay(1);
e=0;
return;
}
void cmd(int j) //command function
{
P2=j; //put the value on pins
rs=0; //selecting command register
rw=0; //selecting to write
e=1; //strobe enable pin
delay(1);
e=0;
return;
}
void puts(char *a) //puts function to print a string
{
unsigned int p=0;
for(;a[p]!=0;p++)
write(a[p]);
}
void lcd_init(void) // function to initialise the LCD
{
cmd(0x38); //setting 8-bit interface, 2 lines, 5*7 Pixels
delay(1);
cmd(0x0e); //turning on underline visible cursor
delay(1);
cmd(0x01); //clearing screen
cmd(0x80); //moving cursor to the begining of line 1 of LCD
}
void main()
{
quat=half=quat_3=full=spkr_off=1; //configuring as input pins
quat=half=quat_3=full=spkr_off=0; //lowering input pins
spkr_on=1; // making speaker on pin high,as it works on negative logic
while(1)
{
while(quat==0&&half==0&&quat_3==0&&full==0&&spkr_off==0) //condition when tank is empty
{
lcd_init(); // initialising LCD
puts("VACANT"); //printing VACANT on lcd
}
while(quat==1&&half==0&&quat_3==0&&full==0&&spkr_off==0) //condition when tank is quater
{
lcd_init();
puts("QUATER"); //printing QUATER on lcd
}
while(quat==1&&half==1&&quat_3==0&&full==0&&spkr_off==0) //condition when tank is half
{
lcd_init();
puts("HALF"); //printing HALF on lcd
}
while(quat==1&&half==1&&quat_3==1&&full==0&&spkr_off==0) //condition when tank is three-fourth
{
lcd_init();
puts("3/4 FULL"); //printing 3/4 FULL on lcd
}
while(quat==1&&half==1&&quat_3==1&&full==1&&spkr_off==0) //condition when tank is full
{
lcd_init();
puts("FULL;CLOSE TAP"); //printing FULL;CLOSE TAP on lcd
spkr_on=0;// Enabling speaker
}
while(quat==1&&half==1&&quat_3==1&&full==1&&spkr_on==0&&spkr_off==1)//enabling high speaker_off pin
{
spkr_on=1;//disabling speaker
}
}
}Hi Mehul,
Please find the line at which the error indicates and share it with us. Please copy paste the entire error report here.
respected sir,
I am student of 5th ec and i want to make one mini project based on 8051.
I found project named it “water level indicator”
but there is one problem in it. It programming is given in “c” language. So, can you tell me how to convert “c” programming into assambaly language like 8051.
Hi Vivek,
Most of the programming softwares have an assembly viewer. I guess the Keil also has the same facility. Once you compile the code in C, you can view the assembly code of the same.
respected sir,
I am a student of 5th sem ec I want the program for water level indicator using 8051 plz help me by getting this.
waiting for ur reply.
Hi Nikita,
There are so many examples in the site under the electronic circuits section, here are few links;
