third_party.pigweed.src/pw_digital_io/README.md

This directory contains the `pw` Digital IO Hardware Abstraction Layer (HAL).
This HAL defines interfaces for working with Digital IO lines that provide
different combinations of capabilities (input, output, and/or interrupts).
Hardware specific backends provide implementations of these interfaces for
different hardware platforms.

Warning: This module is under construction and may not be ready for use.
pw_gpio: Add new module and interfaces NOTE: this module will be renamed `pw_digital_io` immediately in a follow-up change. The Digital IO interface represents individual GPIO lines that support some combination of input, output, and/or interrupt functionality. The choice of supported capability, and most other configuration details are left up to the backend implementation.
