1 .. _module-pw_sys_io_stdio:
6 The ``pw_sys_io_stdio`` backend implements the ``pw_sys_io`` facade using
9 Why not just use stdio directly?
10 --------------------------------
12 The nice thing about using ``pw_sys_io`` is that it's rather easy to get a
13 board up and running with a target-specific backend. This means when drafting
14 out a quick application you can write it against ``pw_sys_io`` and, with some
15 care, the application will be able to run on both host and target devices.
17 While it's not recommended to use ``pw_sys_io`` for any production
18 applications, it can be rather helpful for early prototyping.
22 This module requires relatively minimal setup:
24 1. Write code against the ``pw_sys_io`` facade.
25 2. Direct the ``pw_sys_io_BACKEND`` GN build arg to point to this backend.
29 For the most part, applications built with this backend will behave similarly
30 to an application built directly against stdio.
