There is no "per character" blink attribute. You have to blink it with code.
Try this program. This is for a 16x2 LCD.
| Code: |
#include <16F877.H>
#fuses XT, NOWDT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
#include "flex_lcd.c"
//======================================
void main()
{
char line1[17] = {"Hello World"};
char line2[17] = {"This is line 2"};
char blank_line[17] = {" "};
lcd_init();
// Displays lines 1 and 2.
printf(lcd_putc, "%s", line1);
lcd_gotoxy(1,2);
printf(lcd_putc, "%s", line2);
while(1)
{
// Display line1 text for 1/2 second.
lcd_gotoxy(1,1);
printf(lcd_putc, "%s", line1);
delay_ms(500);
// Blank line1 for 1/2 second.
lcd_gotoxy(1,1);
printf(lcd_putc, "%s", blank_line);
delay_ms(500);
}
