## [0.1.0] - 2024-08-19

[b02f0ca](https://github.com/solimike/rppal-pifacedigital/commit/b02f0ca114a4fb168c3bf333ff7f8bab7ea4b736)...[fb663f5](https://github.com/solimike/rppal-pifacedigital/commit/fb663f580dcd1d9459f4afff70737d8c4dbf9de5)

### Features

- Support Raspberry Pi 5. ([c005210](https://github.com/solimike/rppal-pifacedigital/commit/c0052105f002e3342b9e39e5e054fd62c47945d5))

  Support added by bumping dependency on RPPAL.

- Improved API stability expectations. ([fb663f5](https://github.com/solimike/rppal-pifacedigital/commit/fb663f580dcd1d9459f4afff70737d8c4dbf9de5))

  This crate has worked with very few issues
  for many months. V0.1 recognises
  the expectation that there will not be many
  breaking changes in the future.

### Miscellaneous Tasks

- Bump dependency on RPPAL to V0.19. ([509464b](https://github.com/solimike/rppal-pifacedigital/commit/509464bae82873d8125b9c1c9269cebff96262ae))

  Some minor API breakages but none that break our API.

## [0.0.5] - 2023-01-22

[5549d05](https://github.com/solimike/rppal-pifacedigital/commit/5549d051bac5b2b48ce6dfc7e4aac7a7f70ce3d4)...[b02f0ca](https://github.com/solimike/rppal-pifacedigital/commit/b02f0ca114a4fb168c3bf333ff7f8bab7ea4b736)

### Features

- Async interrupts ([#7](https://github.com/solimike/rppal-pifacedigital/issues/7)) ([cadfa78](https://github.com/solimike/rppal-pifacedigital/commit/cadfa78bfb03062dd5a520b6b8313d2a160f6f26))

  Support async interrupts: when an interrupt occurs, the specified callback or closure
  gets invoked from its own thread.

## [0.0.2] - 2022-11-14

[4dd2cad](https://github.com/solimike/rppal-pifacedigital/commit/4dd2cadc414509f6186863f77454880a614e29d3)...[6a93a4b](https://github.com/solimike/rppal-pifacedigital/commit/6a93a4b96a502f4cd78a7082dad3b2d8a68c19f4)

### Documentation

- Basic badges. ([#2](https://github.com/solimike/rppal-pifacedigital/issues/2)) ([d07a4aa](https://github.com/solimike/rppal-pifacedigital/commit/d07a4aa0c6c4eb9f65002ed474ee4cf038a5d2cc))

  Add some badges to the README so users get some idea of the status on crates.io _etc_. Until some CI is set up, 
  the build badge remains a "TODO".

### Features

- Add examples ([#4](https://github.com/solimike/rppal-pifacedigital/issues/4)) ([7e0da6d](https://github.com/solimike/rppal-pifacedigital/commit/7e0da6d18ec96e786820b43fa7d07ee5bbe50c1a))

  Added some examples in the `examples` folder:
  
  - Blinking LED with interrupt handling.
  - SPI bus speed and reliability test.

### Testing

- Feature flag `mockspi` ([#3](https://github.com/solimike/rppal-pifacedigital/issues/3)) ([efd2c31](https://github.com/solimike/rppal-pifacedigital/commit/efd2c319bc2afa0b374d8a1dd520d6ef0b96c9b9))

  The `mockspi` feature enables testing without access to the Raspberry Pi hardware.

- Basic CI workflow ([#5](https://github.com/solimike/rppal-pifacedigital/issues/5)) ([665babc](https://github.com/solimike/rppal-pifacedigital/commit/665babc6c1c6415d01de04feea4013afb34ee2e1))

  Run a basic workflow to check the integrity of the repo on every push and PR.

## [0.0.1] - 2022-11-11

### Features

- "MVP" PiFace Digital I/O driver ([#1](https://github.com/solimike/rppal-pifacedigital/issues/1)) ([9106240](https://github.com/solimike/rppal-pifacedigital/commit/9106240d78d2c28e5ed7be1a00260d73cbef520a))

  This initial release supports:
  
  - Exposing the underlying capabilities of the *rppal-mcp23s17* crate.
  - Augmenting the `InputPin` with synchronous interrupt capabilities.
  - Polling for synchronous interrupts from a single `InputPin`.
  - Polling for synchronous interrupts across many `InputPin`s.
