Version 0.6.5

Fixed

• Fixed the PinError type not being publicly exposed (#39 by @omelia-iliffe).

Version 0.6.4

Added

• Support for PCA9702 (#37 by @mbrieske).

Version 0.6.3

Added

• Support for PCA9554 and PCA9554A (#36 by @jacobzlogar).

Version 0.6.2

Fixed

• Fixed non-totem-pole devices not having embedded_hal::{InputPin, OutputPin} implementations due to a superfluous trait bound (#35). This was a regression in 0.5.0 (Reported by @tomried).

Bugfix Version 0.5.1

Fixed

• Fixed non-totem-pole devices not having embedded_hal::{InputPin, OutputPin} implementations due to a superfluous trait bound. This fix was backported from 0.6.2.

Version 0.6.1

Added

• Implement polarity and pull-up/down support for MCP23017 and MCP23S17 (#31 by @markus-k).

Version 0.6.0

Added

• Support for MCP23017 (I2C variant) and MCP23S17 (SPI variant) (#27 by @markus-k).

Fixed

• Fixed embedded-hal digital I/O trait implementations being unusable due to usage of an incompatible error type (#30 by @markus-k).

Changed

• BREAKING Pin methods now return a custom error type which wraps the bus error instead of returning the bus error directly (#30 by @markus-k).

Version 0.5.0

Added

• Support for PI4IOE5V6408 (#17 by @t-moe).
• Added support for enabling pull-up/down resistors for port expander input pins (#22 by @t-moe).
• Added public API to access the underlying port-expander of a pin (pin.access_port_driver()) and the register mask for the pin (pin.pin_mask()) (#23 by @t-moe).

Changed

• BREAKING Moved to embedded-hal 1.0 (#16 by @PixmaHestiia).
• BREAKING Replaced shared_bus::BusMutex with our own custom port_expander::PortMutex trait (#26). If you need support for custom mutex types, you now need to implement the latter one for your mutex.

Version 0.4.1

Added

• Added support for TCA6408A (#12 by @PixmaHestiia).
• Added support for PCAL6408A and PCAL6416A (#13 by @Sympatron).

Version 0.4.0

Changed

• BREAKING Upgraded to shared-bus 0.3.
