hi,
i m using jhd 16x2 lcd where i m sending string of data greater than a row .can any body suggest me what should be the command or code to show this data on to next row as well.
 

Hi,

Use string length built in function to calculate the length of string and if the characters are greater than a row print first 15 and use if condition to print rest on to the second line. An example of how to calculate string length is described in the linkhttps://www.cplusplus.com/reference/cstring/strlen/?kw=strlen

enjoy!

    while(*str){
 
        if(ctr < 17)lcd_cmd(0x80 + ctr)
        if((ctr >=17) && (ctr < 33))lcd_cmd(0xC0 + ctr - 16)
        lcd_data(*str++);
        ctr++;

Try this code...
Hope you know the code to write for lcd_cmd and lcd_data and delay..
Code: 
void lcd_data_string(unsigned char *string)
{
	unsigned short m=0;
	while(string[m]!='\0')
	{
 	  	if(m>16)
               {
                  n=m-17;
                  lcd_cmd(0xc0+n);
                  if(n>16)
                  {
                     m=0; 
                     delay_ms(300);
                     lcd_cmd(0x01);
                   }  
                }              
                lcd_data(string[m]);				  
 	  	m++;
   	}
}
