LCD Problem: Extra character at end of line
PostPosted: Sun Apr 26, 2009 5:30 pm     Reply with quote
Hello all,

I am trying to get an LCD working. It is a 16x2 HD44780 compatible display. I wired it to use the "lcd.c" driver on Using Port D. I can get it to work for the most part, but at the end of every string I display I get and extra "character" displayed.

For example want "Ready..." displayed it will show "Ready...@" the @ is the extra symbol(it actually isn't the @ it is something else, but I am just using the @ as a placeholder). Any ideas?

Here is the code:

Code:
#include <16F887.h>

#use delay(clock=4000000)
#include "lcd.c"

void main() {
while(1){
   lcd_init();            // mandatory
   delay_ms(2000);
   lcd_putc("\fReady...");  // nice and friendly
   lcd_putc("\nLine 2");
   delay_ms(2000);
   lcd_putc("\f");
   

}   
}


I am using CCS V 4.013

You probably have vs. 4.013 which is a bad version. It has the problem
you describe. See this thread:

That was it. I added the extra line in the lcd.c file for "\0" and all is good.

Thanks!
