Do you mean to clear an LCD screen?
Tell us which LCD your using.
Most people do this themself and just reset the screen or
send it spaces. |

If you want to "clear screen" when on a RS-232 UART port. Just print a "form feed"
printf("\f"); |

| Sending ADC conversion values to a PC through RS232. I have a printf in a loop to constantly update the conversion values. I need a way to clear the data after each loop, in order to keep the conversion values on one line. |

Using ANSI Escape codes will clear the screen
| Code: |
fprintf( stream, "\x1B[2J" );

| Look for those escape codes and instead of clearing the screen you should reposition the cursor and overwrite the old reading with a new one. |
