Changelog

Unreleased

No changes.

0.8.0 - 2024-09-17

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

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

Fixes

  • Enter initialization mode when constructing a CanBuilder (#49).

0.6.1 - 2021-11-15

New Features

  • Updated to defmt 0.3.0 (#47).

0.6.0 - 2021-09-05

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).

0.5.1 - 2021-05-15

New Features

  • Add transmit function that returns the mailbox number, and transmit abort function (#25).
  • Add more methods to acknowledge interrupts (#30).
  • Add Can::free, a way to get back ownership of the raw peripheral (#33).

Fixes

  • The Can::enable_interrupt and Can::disable_interrupt functions now manipulate the correct bits in the interrupt enable register (#29).

Misc

  • Improve documentation of interrupts (#30).

0.5.0 - 2021-03-15

Breaking Changes

  • Update to defmt 0.2.0 (#17).

0.4.0 - 2021-01-23

Breaking Changes

  • Revamp filter and configuration API to allow method chaining (#10 #12).

Bugfixes

  • Wait for SLAK and INAK bits when changing mode (#8).

Misc

  • Clarify comments for the transmit() method (#9).

0.3.0 - 2020-12-28

New Features

  • Configurable mask for masked filters.
  • Implement the embedded-can traits.

Breaking Changes

  • Changes to masked filters required some breaking API changes.

0.2.3 - 2020-12-09

Fixes

  • Fix a panic when aborting transmission of a lower-priority frame.
  • Fix comparison when checking for a lower-priority mailbox.

0.2.2 - 2020-12-05

New Features

  • Add Can::is_transmitter_idle.

0.2.1 - 2020-12-05

Breaking Changes

  • Update SlaveFilters::enable_bank to also take impl Into<T>.

0.2.0 - 2020-12-05

New Features

  • Add associated constants for highest/lowest CAN IDs.

Fixes

  • Update bank count when changing filter bank split.
  • Fix filter bank logic and document the expected behavior.
  • Fix filter accesses for the slave peripheral.
  • Fix DLC range check in Frame::new_remote.
  • Fix PartialEq implementation of Frame.

Breaking Changes
