Crate nxp_pac

Expand description

§nxp-pac

This is a Peripheral Access Crate for NXP microcontrollers.

MCXA MetaPAC devices are generated at build time from the curated YAML and chip metadata packaged in data/, using Git-pinned chiptool. Only the selected chip’s required peripherals are rendered into Cargo’s OUT_DIR; generated Rust is not maintained in the source tree. Curated YAML is authoritative and maintained directly.

Legacy PAC devices retain their checked-in generated sources, originally derived from NXP’s mcux-soc-svd repo.

This crate will (hopefully) be used for embassy-nxp Rust Hardware Abstraction Layer (HAL) for the NXP microcontrollers.

§Cloning

Select exactly one existing chip feature, for example mcxa266 or mcxa287. The pac feature is enabled by default; metadata, rt, and defmt retain their existing roles. Metadata-only host builds are supported with default features disabled. Building a MetaPAC does not require a vendor SVD checkout, external formatter, or generator executable.

Only explicit SVD import and legacy source regeneration require a recursive clone. Import is an onboarding tool, not an automatic update of curated models.

If you forgot this, you can use git submodule update --checkout --init to fetch the submodules.

§License

The contents of this crate are auto-generated and licensed under the same terms as the underlying SVD file, which is licensed by NXP under a BSD-3-Clause license.
