The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

0.16.0 - 2023-07-05

Changed

  • Updated the alpha release of embedded-hal from 1.0.0-alpha.10 to 1.0.0-alpha.11.

0.15.1 - 2023-05-13

Fixed

  • Changed the Error and ErrorKind types from private to public.

0.15.0 - 2023-04-22

Changed

  • Updated the alpha release of embedded-hal from 1.0.0-alpha.9 to 1.0.0-alpha.10.

0.14.0 - 2022-11-27

Changed

  • Removed lifetimes on OutputPin, InputPin, I2c, Spi, and SpiDevice to improve ease-of-use.

0.13.0 - 2022-09-28

Changed

  • Updated the alpha release of embedded-hal from 1.0.0-alpha.8 to 1.0.0-alpha.9.

0.12.0 - 2022-09-03

Added

  • Added re-exports for libftd2xx and ftdi when the respective feature is used.
  • Added embedded-hal version 1.0.0-alpha.8 trait implementations for:
    • GPIOs
    • Delay
    • SPI

Changed

  • Changed the embedded-hal version 0.2 re-export name from embedded-hal to eh0 to differentiate from embedded-hal version 1.0.0-alpha.8.

0.11.0 - 2022-01-18

Added

  • Added support for input pins.

Changed

  • The ad0 - ad7 methods to get an OutputPin now return a Result to support input pins, previously these methods were infallible.

0.10.0 - 2021-11-08

Added

  • Added support for libftdi1 as a backend.

Changed

  • Renamed to ftdi-embedded-hal.
  • The ftd2xx backend is no longer enabled by default.
  • Changed the error type to support multiple backends.
  • Updated the edition from 2018 to 2021.

0.9.1 - 2021-08-10

Fixed

  • Call close() on Drop, allowing recovery from failures in init().

0.9.0 - 2021-07-01

Changed

  • Updated the libftd2xx dependency from 0.29.0 to 0.31.0.

0.8.0 - 2021-05-29

Changed

  • Updated the libftd2xx dependency from 0.28.0 to 0.29.0.

0.7.0 - 2021-04-18

Added

  • Added checks for missing ACKs from the I2C slave. Missing ACKs will now return an NakError from the I2C traits.

Changed

  • Changed the default implementation of I2C traits to wait for a slave ACK before transmitting more bytes. The previous behavior can be retained by calling set_fast(true).

0.6.0 - 2021-04-10

Added

  • Added support for the FT4232H.
  • Added support for the FT2232H.

Changed

  • Changed the default linking method on Linux to dynamic. Static linking can be enabled with the static feature flag.
  • Changed the I2C pins to input (tri-state) when in idle mode.

Fixed

  • Fixed AD0 (SCL) pulling low when when I2C is first initialized.
  • Fixed I2C AD0 & AD1 (SCL & SDA out) being pulled low when another OutputPin changed state.

0.5.1 - 2021-03-20

Fixed

  • Fixed the I2C Read trait not setting the read address bit.
  • Fixed the I2C Write trait not driving SDA as an output when clocking data out.

0.5.0 - 2021-03-20

Added

  • Added checks for pin allocation, trying to take output pins 0-2 while using the SPI interface will now result in panic.
  • Added I2C traits.
  • Added Debug for interface structures.
  • Added with_serial_number and with_description constructors.

Changed

  • Changed the FTDI MPSSE initialization to occur once globally for the device instead of inside the SPI device trait.
  • Changed the Delay structure to contain dummy data for possible future use.
  • Change the Ft232hHal::with_ft to impl From<Ft232h> for Ft232hHal.

Removed

  • Removed Eq and PartialEq traits on the Delay structure.

0.4.0 - 2021-03-05

Added

  • Added a Delay structure that implements the embedded-hal delay traits.

Changed

  • Updated libftd2xx dependency from 0.24.0 to 0.25.0. This updates the vendor library from 1.4.8 to 1.4.22 for Linux targets. This should fix timeout conditions that previously occurred when rapidly toggling GPIO pins.

0.3.0 - 2021-02-14

Changed

  • Improved latency for GPIOs

Fixed

  • Fixed the example code for Ft232hHal::new.
  • Fixed pins 5, 6, 7 not being usable as outputs.

0.2.0 - 2020-09-13

Added

  • Added SPI non-blocking traits.

Changed

  • Updated to libftd2xx 0.17.0
  • Updated to embedded-hal 0.2.4

0.1.0 - 2020-09-12

  • Initial release
