v0.8.0

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.

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 ().

v0.6.2

Fixes

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

v0.6.1

New Features

• Updated to defmt 0.3.0 (#47).

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).

v0.5.1

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).

v0.5.0

Breaking Changes

• Update to defmt 0.2.0 (#17).

v0.4.0

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).

v0.3.0

New Features

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

Breaking Changes

• Changes to masked filters required some breaking API changes.

v0.2.3

Fixes

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