bad CHARACTER

[ccmcca]

Why apear extrange character at the end of the line???
Please help me...

#include <16F877.h>
#device *=16
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)

#include <HDM64GS12.c>
#include <graphics.c>


void main()
{

int i;
CHAR const my_string[]="hola amigos";
CHAR const my_string2[]="aca estoy";
CHAR const my_string3[]="todo lison";
CHAR const my_string4[]="entrar aqui";



char buffer[];

glcd_init(ON);

for (i=0;i<=20;i++)
buffer[i]=my_string[i];
glcd_text57(5, 1,buffer, 1, ON);


for (i=0;i<=20;i++)
buffer[i]=my_string2[i];
glcd_text57(5, 9,buffer, 1, ON);

for (i=0;i<=20;i++)
buffer[i]=my_string3[i];
glcd_text57(5, 17,buffer, 1, ON);

for (i=0;i<=20;i++)
buffer[i]=my_string4[i];
glcd_text57(5, 25,buffer, 1, ON);



#ifdef FAST_GLCD
glcd_update();
#else
delay_ms(100); // Reduces flicker by allowing pixels to be on
// much longer than off





}

You didn't declare the size of buffer[].

I guess the "glcd_text57()" function checks for a NULL. We don't know what the parameters are.

That´s because the display is showing you all the variables in the
boundaries of your stored string.

To display the string[]="hola amigos" you use
for (i=0;i<=20;i++)
where the string "pointer" has a range i<= 20
while your message is only 10 characters long.

Try putting a null at the end of your string and
break the for cycle when detected.

Mark,

I know that but he didn´t post the function definition for

glcd_text57(5, 1,buffer, 1, ON);

so we didn´t know for sure if he is looking for a NULL as end of char string recognition.

Didn't I already say that?

[Humberto]

Mark,

I know what the problem is and how to solve it. FYI it is not my inquiry,
it is a thread posted by ccmcca and I just put the spot on the subject
I think the problem is and I hope this were solved by ccmcca.

Actually this is CCS driver file
