## [Unreleased]

## Added

- Updated to embedded-hal 1.0.0 and embedded-hal-async 1.0.0
- New `AsyncWriteOnlyDataCommand` trait.
- i2c, spi: `async/await` support.
- parallel-gpio: Added `Generic16BitBus`
- parallel-gpio: Added `PGPIO16BitInterface`
- added `defmt-03` feature

## Changed

- **Breaking** raised MSRV to 1.75
- spi: `SPIInterface` now wraps objects that implement the `SpiDeviceWrite` trait from embedded-hal 1.0.0
- spi: `SPIInterface` now wraps objects that implement the `SpiDeviceWrite` trait from embedded-hal-async 1.0.0
- parallel-gpio: Fixed bug with fallible pins
- **Breaking** parallel-gpio: `GenericxBitBus::new` is now infallible

## [v0.4.1] - 2021-05-10

### Added

- New `DisplayError` variant `RSError` to use with problems with the display's reset signal
- New `DisplayError` variant `OutOfBoundsError` to use when writing to a non-existing pixel outside the display's bounds
- parallel-gpio (0.5.0): New `OutputBus` trait
- parallel-gpio (0.5.0): Added `Generic8BitBus`, an implementation of `OutputBus`

### Changed

- Return `DCError` instead of `BusWriteError` on errors (de-)asserting the DC signal in 8-bit GPIO interfaces
- **Breaking** parallel-gpio (0.5.0): `PGPIO8BitInterface` now uses any 8-bit impementation of `OutputBus` instead of 8 individual pins

## [v0.4.0] - 2020-05-25

### Added

- Support for 8bit and 16bit iterators as data format
- Support for 16bit slice data format with target endian
- Deconstructors for included display-interface implementations

### Changed

- Make enums non-exhaustive and added a DataFormatNotImplemented fallback error

## [v0.3.0] - 2020-05-11

### Added

- 16 bit data width support for 8 bit parallel-gpio and SPI impls

### Changed

- Data width is provided via custom enum (breaking change)

## [v0.2.1] - 2020-04-16

### Added

- Added prelude

## [v0.2.0] - 2020-04-01

### Changed

- Made data width generic (breaking change)

## [v0.1.1] - 2020-03-29

### Fixed

- Crate metadata

### Removed

- Examples requiring additional driver crates

## 0.1.0 - 2020-03-29
