Zephyr Hardware I/O

Interface with the physical world using Zephyr's standardized driver models and hardware abstraction layers.

Core Workflows

1. Sensor Subsystem

Interact with various sensors using a uniform API for data fetching and decoding.

• Reference: sensors.md
• Key Tools: sensor_sample_fetch, sensor_channel_get, struct sensor_value.

2. Pinctrl & GPIO

Manage pin multiplexing, electrical configuration, and basic digital input/output.

• Reference: pinctrl_gpio.md
• Key Tools: pinctrl, gpio_dt_spec, GPIO_DT_SPEC_GET.
