![]() ![]() You can make it all a lot neater by positioning the cursor to a position where you want to print and only change what is needed. 3 Erase the scroll-back (aka Saved Lines) Note that this only erases the scroll-back, not the screen. Wherever you want to clear the screen, call them void loop() TeraTerm or RealTerm under Windows.īelow are two functions that you can use with 3rd party terminal programs that support ANSI escape sequences. So the solution is to look at ANSI escape sequences yourself and use a 3rd party terminal program that supports ANSI escape sequences e.g. The following code example uses the Erase in Display sequence that clears the entire screen and does not delete the scrollback buffer. ![]() Or for a software virtual terminal such as probably you are actually using, it depends on the software involved and its configuration. Some extra code preferably needs to be added to the Serial class so it can tell the Serial Monitor what to do this is actually outside the purpose of the class so a derived class will be needed. ANSI codes include multiple console output sequences with features like moving the cursor up/down, erasing in line, scrolling, and several other options. The effect of control codes, such as the ANSI escape sequence you're trying to use, depends on the terminal you write them to.Serial Monitor needs to support it which is not the case.Only ESC H + ESC J really 'clears' the currently showed contents on the screen. You could also refer to this Wikipedia page. Some useful ANSI control sequences are described in the following table. However, ESC 2J doesnt really 'clear' the screen, it just scrolls down to 'hide' printed contents. Alternatively, we can insert the same escape sequence with a slight modification (substitute 2 with 3) to clear the whole console screen and delete the scrollback buffer, as shown in the next code sample. I'm reasonably sure that requests have been made in the past (at least for 1.8.x, possibly for 2.0 as well) to support ANSI Escape sequences in the Serial Monitor. The new Windows console supports ANSI (VT100) control codes: ANSI/VT100 control codes & Windows document: the control codes. There are a bunch of Linux programs that make use of ANSI escape sequences in order to, for example, change the text color, or clear the screen. ![]()
