Can someone suggest how to avoid the allocation in DSEG (which is
overfull) in the following code snippet?
...
void lcd_puts (char xdata *str)
{
uint8 xdata i;
for (i=0; str[i] != '\0'; i++) {
lcd_datas (str[i]);
}
}
/*---------------------------------------------------------------------------*/
void lcd_set_text (uint8 xdata row, char xdata *lcd)
{
lcd_gotoxy (0, row);
lcd_puts (lcd);
}
...
which produces an allocation in DSEG for the argument (which it seems
desirable to avoid as it fills DSEG reasonably quickly on the 8051):
...
