# DEVNULL
|
|
|
|
Arduino library for a /dev/null stream
|
|
|
|
## Description
|
|
|
|
The library implements a stream class that mimics the /dev/null
|
|
device of a linux system. You can write everything to it, you can
|
|
never read data from it as it always returns EOF (end of file);
|
|
|
|
THe 0.1.0 version is a minimal implementation that can be optimized.
|
|
Now it only implements the **write()** call and e.g. a float is still
|
|
converted to individual characters that are send one after another.
|
|
Strings and text send every byte.
|
|
|
|
The advantage is that printing takes time and e.g. one can use it to measure
|
|
the **print** class performance.
|
|
|
|
Performance can be increased by implementing all methods of the print interface
|
|
with only a return 0;
|
|
|
|
## Operation
|
|
|
|
use with care
