# [unreleased]

# [v0.5.1] 2025-03-10

## Fixed

- Fix `embedded_io` UART implementation to implement the documented contract properly.
  The implementation will now block until at least one byte is available or can be written, unless
  the send or receive buffer is empty.

# [v0.5.0] 2025-03-07

- Bugfix for I2C `TimingCfg::reg`
- Simplified UART error handling. All APIs are now infallible because writing to a FIFO or
  reading from a FIFO never fails. Users can either poll errors using `Rx::poll_errors` or
  `Uart::poll_rx_errors` / `UartBase::poll_rx_errors`, or detect errors using the provided
  interrupt handlers.

# [v0.4.1] 2025-02-18

- Chip selection is not enforced anymore, but advised through documentation. This makes using
  the HAL in libraries a lot easier.

# [v0.4.0] 2025-02-18

## Changed

- GPIO API: Interrupt, pulse and filter and `set_datamask` and `clear_datamask` APIs are now
  methods which mutable modify the pin instead of consuming and returning it.
- Simplified PWM module implementation.
- All error types now implement `core::error::Error` by using the `thiserror::Error` derive.
- `InvalidPinTypeError` now wraps the pin mode.
- I2C `TimingCfg` constructor now returns explicit error instead of generic Error.
  Removed the timing configuration error type from the generic I2C error enumeration.
- `PinsA` and `PinsB` constructor do not expect an optional `pac::Ioconfig` argument anymore.
- `IrqCfg` renamed to `InterruptConfig`, kept alias for old name.
- All library provided interrupt handlers now start with common prefix `on_interrupt_*`
- `RxWithIrq` renamed to `RxWithInterrupt`
- `Rx::into_rx_with_irq` does not expect any arguments any more.
- `filter_type` renamed to `configure_filter_type`.
- `level_irq` renamed to `configure_level_interrupt`.
- `edge_irq` renamed to `configure_edge_interrupt`.
- UART interrupt management is now handled by the main constructor instead of later stages to
  statically ensure one interrupt vector for the UART peripheral. `Uart::new` expects an
  optional `InterruptConfig` argument.
- `enable_interrupt` and `disable_interrupt` renamed to `enable_nvic_interrupt` and
  `disable_nvic_interrupt` to distinguish them from peripheral interrupts more clearly.
- `port_mux` renamed to `port_function_select`
- Renamed `IrqUartErrors` to `UartErrors`.

## Added

- Add `downgrade` method for `Pin` and `upgrade` method for `DynPin` as explicit conversion
  methods.
- Asynchronous GPIO support.
- Asynchronous UART TX support.
- Asynchronous UART RX support.
- Add new `get_tim_raw` unsafe method to retrieve TIM peripheral blocks.
- `Uart::with_with_interrupt` and `Uart::new_without_interrupt`
- A lot of missing `defmt::Format` implementations.

# [v0.3.0] 2024-30-09

## Changed

- Improve and fix SPI abstractions. Add new low level interface. The primary SPI constructor now
  only expects a configuration structure and the transfer configuration needs to be applied in a
  separate step.
- Added an additional way to read the UART RX with IRQs. The module documentation provides
  more information.
- Made the UART with IRQ API more flexible for future additions.
- Improved UART API result and error handling, added low level API to read from and write
  to the FIFO directly

## Fixed

- Fixes for SPI peripheral: Flush implementation was incorrect and should now flush properly.
- Fixes for SPI example
- Fixes for RTIC example

# [v0.2.0] 2024-09-18

- Documentation improvements
- Improved UART typing support: Validity of passed pins is now checked properly

## Changed

- Added `va41620`, `va41630`, `va41628` and `va41629` device features. A device now has to be
  selected for HAL compilation to work properly
- Adaptions for the UART IRQ feature which are now only implemented for the RX part of the UART.

## Fixed

- Small fixes and improvements for ADC drivers
- Fixes for the SPI implementation where the clock divider values were not calculated
  correctly
- Fixes for UART IRQ handler implementation
- Add new IRQ router initialization method `irq_router::enable_and_init_irq_router`. This method
  also sets the initial values of some registers to 0 where the datasheet and the actual reset
  value are inconsistent, which can lead to weird bugs like IRQs not being triggered properly.

## Added

- Added basic DMA driver
- Added basic EDAC module
- Added bootloader and flashloader example application
- Added NVM module which exposes a simple API to write to the NVM memory used for the boot process

# [v0.1.0] 2024-07-01

- Initial release with basic HAL drivers
