pw_sys_io_stdio

The pw_sys_io_stdio backend implements the pw_sys_io facade using stdio.

Why not just use stdio directly?

The nice thing about using pw_sys_io is that it's rather easy to get a board up and running with a target-specific backend. This means when drafting out a quick application you can write it against pw_sys_io and, with some care, the application will be able to run on both host and target devices.

While it's not recommended to use pw_sys_io for any production applications, it can be rather helpful for early prototyping.

Setup

This module requires relatively minimal setup:

  1. Write code against the pw_sys_io facade.
  2. Direct the pw_sys_io_BACKEND GN build arg to point to this backend.

Module usage

For the most part, applications built with this backend will behave similarly to an application built directly against stdio.
