I want to send data through variable through LCD.
and I am using flex_lcd drive.
my LCD is struck, and the pin c6 get high.
| Code: |
#include <18F4520.h>
#FUSES NOPROTECT,NOWDT,NOLVP,HS,NOBROWNOUT
#use delay(clock=10000000)
#include <flex_lcd.h>
float phase_angle = 13.6;
float firing_angle = 10.5;
int cap_bnk=12;
void main()
{
lcd_init();
while(1)
{
sprintf(LCD_putc,"\f %u",phase_angle);
delay_ms(100);
lcd_gotoxy(0,1);
sprintf(LCD_putc,"FA:%u",firing_angle);
delay_ms(100);
lcd_gotoxy(0,2);
sprintf(LCD_putc, "Cap:%u",cap_bnk);
delay_ms(100);
}
} |
I tried fprintf,sprintf and printf. I heard that these are UART functions.
please help |

Read the CCS manual. Or just google sprintf. You are 2nd person within
a short time period who uses sprintf incorrectly. The output of sprintf
goes to a RAM buffer. It never goes to an i/o function or a stream.
For that, you should use printf.
Also, read the CCS manual for printf. %u is not the format specifier
for a floating point variable. The manual (in the printf section) will
tell you what the correct format specifier is.

Even one more thing !
You are using 0 as a parameter in the lcd_gotoxy() function. But the
function specification given in the CCS driver file, lcd.c, does not say you
can do that. It say this:
| Quote: | | lcd_gotoxy(x,y) Set write position on LCD (upper left is 1,1) |
You need to read the documentation for every function before you use it. |
