10. Variables and text In addition to simply displaying a specific string, sometimes we need to display some variables on the screen, such as time and sensor values, etc. Then, depending on the type of the variable, you can choose to use the following different functions. drawChar(int...
but it is structured differently, as a C++ class. This is a bit more difficult to read (when you are used to standard Arduino programming and not C++ programming) but has the advantage that the functionality can easily be reused in other servers. Actually, most standard modules (below) star...
