Driver for the STM32 bxCAN peripheral.
This crate provides a reusable driver for the bxCAN peripheral found in many low- to middle-end STM32 microcontrollers. HALs for compatible chips can reexport this crate and implement its traits to easily expose a featureful CAN driver.
- Supports both single- and dual-peripheral configurations (where one bxCAN instance manages the filters of a secondary instance).
- Handles standard and extended frames, and data and remote frames.
- Support for interrupts emitted by the bxCAN peripheral.
- Transmission respects CAN IDs and protects against priority inversion (a lower-priority frame may be dequeued when enqueueing a higher-priority one).
- Optionally implements the
embedded-cantraits for interoperability.
- Currently, only RX FIFO 0 is supported, and FIFO 1 will not be used.
- Support for querying error states and handling error interrupts is incomplete.
