pw_interrupt_zephyr

Unstable

This is the Zephyr RTOS backend for the pw_interrupt facade. It uses k_is_in_isr() to determine whether the current context is an interrupt service routine.

Setup

Bazel

Set the backend flag in your platform definition or build options:

platform(
    name = "my_zephyr_platform",
    flags = flags_from_dict({
        # ...
        "@pigweed//pw_interrupt:backend": "@pigweed//pw_interrupt_zephyr:context",
    }),
)

Or via your project’s .bazelrc:

build --@pigweed//pw_interrupt:backend=@pigweed//pw_interrupt_zephyr:context

Zephyr (CMake / Kconfig)

The backend is controlled by choice PIGWEED_INTERRUPT_CONTEXT_BACKEND (see How backend selection works) and defaults to Pigweed’s Zephyr backend.

To supply your own backend instead, select NONE:

CONFIG_PIGWEED_INTERRUPT_CONTEXT_NONE=y
