c coding syntax error- how to send value stored in buffer?

c coding help

I am putting analog input from 0 to 5 v in PIC 18.
Now the A/D result is saved in a register "result" type int.
Now i want to convert the values stored in "result" to ASCII and then to display on LCD.
I have Vref of A/D as 5 volt and using in 10 bit mode.
I want LCD to show fractional values too like 4.5 etc
My coding is
#include <stdio.h>

char buffer[8];

void convert(void)
{
int result;
double voltage;

voltage = (double)(result * 5.0 / 1024.0);
sprintf(buffer, "%0.1f", voltage);
}
i have problem that LCD data lines are connected to port D(D0 to D7).Now when i use the following code to send data stored in buffer[] i get syntax error.
PORTD=buffer[];
so how can i send the value stored in buffer[] to PORT D.

How can you send whole string to the lcd this way.
PORTD=buffer[];

Your sprintf function has converted the voltage into string buffer. Now u need to access that character array one by one and put those character into lcd.

for eg.
for(i=0;i<8;i++)
lcd_putch(buffer);

or

while(*buffer)
lcd_putch(*buffer++);

But u need to have a function for sending a character into lcd in a proper way, after initializing the lcd ofcourse.
