Hi, Im trying to display string to lcd using following code:
void LCD_String(unsigned char *s)
{
LCD_Char(*s);
LCD_Char(*(s+1));
LCD_Char(*(st+2));
LCD_Char(*(s+3));
return;
}
called with LCD_String(text); in main(), text is unsigned char text[10];
declared outside main() and initialized with "Test\0" in main().
Program displays just T[glyph/rand char][glyph/rand char][glyph/rand char]
[glyph/rand char].
But:
void LCD_String(unsigned char *s)
{
LCD_Char(*s);
s=text;
LCD_Char(*(s+1));
s=text;
LCD_Char(*(st+2));
s=text;
LCD_Char(*(s+3));
return;
}
works fine and displays Test, so I suspect so LCD_Char(*s) call destroys s.
Why is this happening and how can I prevent it? Thanks.
