Release v0.10.0

Breaking changes

• Update stm32f3 pac to v0.15.1 (#335)
• Update bxcan pac to v0.7.0 (#335)
• Remove Toggle enum and use Switch instead for better naming purposes
• Fix undefined behavior in SPI implementation (#346)
  • Add num_traits::PrimInt bounds to Word
• Remove Serial::split, which possibly creates two mutable references two
  one Serial instance, which could've caused UB. The use case of this function
  was hard to find out anyway. (#351)
• Remove defmt-* features (defmt feature is still available), to finalize
  migration from defmt-0.2.x -> defmt-0.3.x. (#349)
• Removed implicit stm32-usbd feature (use usb instead) (#349)

Added

• Add missing ADC channels (#337 & #345)
• Add many #[must_use] instances (#347)

Fixed

• Fix wrong timer frequency calculation and unexpected panics (#338)
• Fixed integer saturation in Timer::start, see #342 (#356)

Changed

• The PWM implementation was deprecated. There is not yet an alternative
  implementation, but it is hard to maintain the current implementation
  and not easy to verify if it is really a safe implementation.
  It is also not consistent with the rest of the crates API. (#352)
• Use critical-section crate instead of interrupt_free, which is not always
  sound. (#350)
  It is also not consistent with the rest of the crates API.
• The MSRV was bumped to 1.60 (#349)

Release v0.9.2

Added

• Add missing ADC channels (#337)

Fixed

• Fix wrong timer frequency calculation and unexpected panics (#338)

Changed

• The MSRV was bumped to 1.59 (#340)

Release v0.9.1

Added

• Add a minimal DAC driver (#318)

Fixed

• Missing MosiPin impl for PB5 (#322)
• Read valid data from data register even if reception of next character
  has started (#317)

Release v0.9.0

Added

• Generic into_af_push_pull<A> and into_af_open_drain<A> (#308)
• BusClock and BusTimerClock traits (#302)
• RccBus, Enable, Reset traits and implementations for peripherals (#299)
• Support cortex-m-rt v0.7.0 but still allow v0.6.13 (#283)
• Make timer InterruptTypes fields public to be useful. (#304)
• Add support for the internal signature peripheral (#281)
• Add common derives to Toggle. (#281)
• Add is_interrupt_configured and configured_interrupts function to
  serial::Serial and timer::Timer. (#281)

Fixed

• Fix can support. Can would not build for stm32f302x6 for example.
  Also support can for every chip other than stm32f301 and stm32f318.
  (#283)
• Fix wrong ADC votlage regulator startup time calculation effecting
  calibration. (#281)

Breaking Changes

• Make rtc an optional feature. Without that feature rtcc as a dependency is
  not needed. (#283)
• Update rtcc to v0.3.0. For a detailed changelog, go here. (#314)
• Enable rt, usb, can, rtc and ld feature by default.
  To disable that behavior, set default-features = false. (#283)
• The MSRV was bumped to 1.54 (#308)
• Update stm32f3 pac to v0.14.0 (#282)
• Remove the bxcan re-export. (#304)
• The LICENSE has been changed from BSD 0-clause to the familiar dual license
  MIT / Apache 2.0. This has been done, as this fits the ecosystem better and
  the dependencies where using the MIT / Apache 2.0 dual licensing already,
  which resulted into the situtation, that BSD 0-clause was not affectivly
  0-clause as MIT conditions had to be met anyways. (🧂 IANAL). (#309)
• Renamed Serial::raw_read to Serial::read_data_register. (#281)
• Seal FlashExt and RccExt traits. These are no longer implementable by
  a user of this crate. (#281)
• Move ADC from a macro to a generic implementation, meaning that
  it is possible to obtain an ADC instance via Adc::new instead of
  Adc::adc1. (#281)
• Remove adc::ClockMode and the clock configuration of the ADC.
  • Clock configuration effects the common ADC which inturn controls e.g. ADC1
    and ADC2, which the old API did not resemble.
  • The API provides no clock configuration for ADC peripherals yet, but
    correctly acts upon changes done through the pac. (#281)
• Major rework of the ADC implementation: (#281)
  • Add CommonAdc support.
  • Add internal sensor peripheral support like TemeperaturSensor and similar.
  • Lift restriction of the ADC implementation for stm32f303, though
    stm32f373 is still not supported.
  • Enable manual configuration of the Adc peripheral of most important features
    • ConversionMode
    • Sequence length
    • OverrunMode
    • etc.
  • Leverage type states to:
    • Allow a Disabled ADC, which can be manually calibrated.
    • Allow a OneShot ADC implementation through into_oneshot with an
      optimal configuration for the OneShot embedded-hal trait.
  • Support every possible ADC channel.
  • Add interrupt support.

Release v0.8.2

Added

• Add missing SPI impls for the gpio-f303 device groups (e.g. stm32f303vc) (#304)

Release v0.8.1

Fixed

• ADC Channel SMP Register mismatch. (#291)
  • While read()ing a Pin mapped to channel 10 and unexpected panic happened.

Release v0.8.0

Added

• Readd MonoTimer. This was accidentally removed before. (#247)
  • Different to before, frequency() and now() now do not consume the MonoTimer.
    &self is used instead. (#267)
• Basic serial implementation also available for UART4 and UART5 (#246)
• Implement serial DMA also for Serial (#246)
• Add enumset as a optional dependency, which allow more ergonomic functions
  regarding enums. This is especially useful for status event query functions.
  (#253)
• As serial Error and serial Events share things in common. TryFrom<Event>
  and From<Error> is implemented for conversions. (#253)
• Add serial character match function, with which events can be triggered for
  the set character. (#253)
• Add receiver timeout function, which configures the serial peripheral to
  trigger an event, if nothing happened after a certain time on the serial
  receiver line. (#253)
• Add raw_read() function, which does no error handling and also does not
  clear any Event by itself. Useful, if the error_handling has to be done in
  another context (like an interrupt rountine). (#253)
• Introduce Toggle, with On and Off as a convinience wrapper around bool
  for configuration purposes. (#253)
• Add an associated const to serial::Instance to return the corresponding
  pac::Interrupt-number, which is useful to unmask() interrupts.
  An interrupt() function to Serial was also added for convinience. (#253)
• Add a Serial::is_busy() function to check, if the serial device is busy.
  Useful to block on this function, e.g. while serial.is_busy() {}. (#253)
• Add BaudTable a convinience wrapper around Baud to configure the Serial
  to the most commen baud rates. (#253)
• Add Serial::detect_overrun() function, to en- or disable the overrun
  detection of the Serial. If overrun is disabled (enabled by default), than
  newly arrived bytes are overwriting the current data in the read receive
  register without throwing any event. (#253).
• Lift generic constraint of most Serial method on TxPin and RxPin.
  This should make it easier to generically use the Serial peripheral. (#253)
• Greatly increase coverage of Debug and defmt::Format implementations.
  Almost all important types should now be supported. (#265)
• Add a free() function to the RTC implementation to retrieve the passed-in
  peripheral. (#266)
• Implement an API to return the corresponding interrupt number of timer through
  the newly introduced InterruptNumber trait, where the Interrupt is held
  as an associated const. (#267)
  • Depending on the timer one Interrupt or a bundle of InterruptTypes is
    returned.
  • On the bases of these interrupts, the interrupt controller (NVIC) can
    be set to mask or unmask these interrupts.
• Implement the embedded-hal::timer::Cancel trait for timers. (#267)
• Add use_pll to CFGR - the clock configuration - to force to use the PLL
  source for the systemclock. Also Clocks::pllclk() was introduced to be able
  to check, whether PLL is used.
• Add unsafe peripheral function to access underlying peripheral (#277)
• Implement fmt::Write for Serial (#278)
  • This allowes using writeln! in combination with Serial.

Changed

• PXx struct (representing a generic GPIO pin) implements Send and Sync (#251)
• Each pin aliases (PA0, PA1, ..) are defined under gpio module directly.
  Re-export from gpio port sub-modules are provided for compatibility. (#257)
• The embedded-hal Read implementation of Serial does now return WoudBlock
  if the peripheral is busy. Also if an Overrun occured the receive data
  register (RDR) is flushed to have a more consistent API. (#253)
• Remove cargo-metadata as a build dependency to cut down dependencies and
  the reliance on resolver = "2". (#270)

Fixed

• The "unproven" feature, which itself does enable the "embedded-hal/unproven"
  features, can no longer be disabled. (#259)
  1. The "unproven" features are no longer unproven and used anywhere anyways.
  2. This crate was not building successfully without the unproven feature.
• Set the correct baud rate for chips where USART1SW_A::PCLK leads to a
  baud rate derived from PCLK1, rather than the ports own bus clock, PCLK2.
  (#260)

Breaking Changes

• Refactor CAN to use the bxCan crate. (#207)
• Add support for configuring parity and stop bits in addition to baud rate for
  Serial with serial::config::Config. (#239)
• Implement Serial::join which allows to re-create the serial peripheral,
  when Serial::split was previously called. (#252)
• Parameterized usb::Peripheral and usb::UsbType on the pin configuration
  used (#255)
• Add (almost) all missing serial (interrupt and status) events.
  Also rename all the event names to be more descriptive. (#253)
• A new serial interrupt API was introduced: (#253)
  • listen() and unlisten() are renamed to enable_interrupt() and
    disable_interrupt().
  • is_tc() and other non-parametrizable functions are removed.
  • configure_interrupt() was added, which can be parameterized.
  • clear_event() was added to clear specific events.
  • clear_events() was added to clear all events at once.
  • is_event_triggered() can check if an Event is triggered.
  • triggered_events returns an EnumSet of triggered events.
• Change gpio interrupt API to be more in line with the new serial interrupt
  API. (#262)
• Move EXTI interrupt management to SysCfg. (#262)
  • Becuase EXTI interrupt confiugration could cancel out, make it more obvious
    in that SysCfg manages the interrupts, not the pin itself.
    Change make_interrupt_source() to SysCfg::select_exti_interrupt_source().
• Change dma interrupt API to be more in line with the new serial interrupt
  API. (#263)
• Change timer interrupt API to the same of the serial interface. (#264)
• Make timer Events #[non_exhaustive]. (#264)
• Renames timers release() function to free() to be more in line with the
  rest of this crate. (#264)
• rtc's Error type and OperationMode and CkMode of adc are now #[non_exhaustive].
  (#266)
• All non-camel-case types are chaged to be consistently camel-case types.
  Types which do not follow these rules are re-exported types by stm32f3 for
  example. (#266)
• Adc's SampleTime type has been reworked and is now a consistent wrapper around
  the underlying types for stm32f3's SMP9_A and SMP18_A type. (#266)
• Rename CkMode to ClockMode (#266)
• Rename stm32-usbd feature to usb. stm32-usbd is still used as a
  dependency. (#271)
• Rework the timer implementation: (#267)
  • PclkSrc trait was removed in favor of generic Instance trait, which
    is a common ground for all available timers.
  • Timer::tim1 and so on are renamed to Timer::new
  • The implementation of the timers are corrected to better represent the
    avaibilities of timers of the hardware.
  • Timer::new now does not take a timeout value. This means, that the
    timer will now not be started automatically and one has to explicitly call
    start().
• Rework SPI implementation: (#273)
  • A generic Instance trait now represents all Spi peripherals.
  • Spi::spi1 and so on are renamed to Spi::new.
  • Add SPI configuration type to be passed into Spi::new
• Remove public fields from Adc and Rtc (#277)
