# Changelog ## Unreleased No changes. ## [0.8.0 - 2024-09-17](https://github.com/stm32-rs/bxcan/releases/tag/v0.8.0) ### Fixes * Mask out all reserved bits in `set_bit_timing` before writing the register. ### Other Changes * Update the embedded hal dependency to use the new embedded-can crate instead. ## [0.7.0 - 2022-05-30](https://github.com/stm32-rs/bxcan/releases/tag/v0.7.0) ### New Features * [*breaking change*] Add support for using the second RX FIFO. * The `Rx` type has been renamed to `Rx0`, and an `Rx1` type has been introduced that accesses the second FIFO. * `enable_bank` now takes the `Fifo` the filter should be assigned to as an additional argument. * Implement the `embedded-hal` 0.2.7 CAN traits. ### Other Changes * [*breaking change*] Removed the `embedded-can-03` feature as the `embedded-can` crate is deprecated. * [*breaking change*] Use a new `OverrunError` type as the receive error instead of `()`. ## [0.6.2 - 2021-11-15](https://github.com/stm32-rs/bxcan/releases/tag/v0.6.2) ### Fixes * Enter initialization mode when constructing a `CanBuilder` ([#49]). [#49]: https://github.com/stm32-rs/bxcan/pull/49 ## [0.6.1 - 2021-11-15](https://github.com/stm32-rs/bxcan/releases/tag/v0.6.1) ### New Features * Updated to defmt 0.3.0 ([#47]). [#47]: https://github.com/stm32-rs/bxcan/pull/47 ## [0.6.0 - 2021-09-05](https://github.com/stm32-rs/bxcan/releases/tag/v0.6.0) ### New Features * Add `CanConfig::set_automatic_retransmit` function to enable or disable automatic frame retransmission ([#42]). * [*breaking change*] Remove `transmit_and_get_mailbox` in favor of an improved `transmit` method ([#40]). * `Can::transmit` now returns a `TransmitStatus` struct, which contains the dequeued frame and the mailbox the new frame was placed into. * [*breaking change*] Make `CanConfig` harder to misuse ([#37]): * Methods now take `self` by value. * The `CanConfig` struct is now `#[must_use]`. * `CanConfig` leaves init mode on drop, and enables the peripheral when `.enable()` is called. * These changes make it very hard to forget to enable the peripheral after configuring, which was a common mistake in previous versions. * [*breaking change*] Replace `Can::new` with `Can::builder`, which makes it harder to forget enabling the peripheral ([#46]). ### Other Changes * [*breaking change*] Make `Can::clear_sleep_interrupt` and `Can::clear_wakeup_interrupt` take `&self` instead of `&mut self`. * [*breaking change*] Gate `embedded_can` impls behind the `embedded-can-03` Cargo feature. * [*breaking change*] Gate defmt support behind the `defmt` Cargo feature. * [*breaking change*] Removed `Can::configure` in favor of `Can::modify_config` ([#36]).
