hi there,
when using printf /n it print a new line on the consol, how do i just make it change the same line (refresh) instead of printing another line.
i have a loop which gives me vaules of my outputs, but i dont want it to print a long list, i just want it to update the same line every few seconds.
does anyone know the code for this?
thanks
piire! |

If you don't want a new line, then don't send the "\n" command.
Just a send a carriage return: "\r" |

Or, for more 'complex' things, use the lcd_gotoxy instruction, to position where you want. So, (for example), if you are on a 2*16 LCD, and have the top line saying "Reading xxx mG", you can use:
| Code: |
int8 val;
lcd_putc('\f'); //Back to the top corner of the display, and clear
printf(lcd_putc,"Reading nnn mG"); //Initialise the message
while (true) {
val=code_to_get_reading();
lcd_gotoxy(9,1); //The location where 'nnn' starts
printf(lcd_putc,"%03d",val; //print the value to fill the 'nnn' space
}
|
This way, you only need to redraw the actual number, not the rest of the text.
