Unreleased

[v0.6.1] - 2020-12-10

Changed

• Removed doc-comment dependency (#184)

v0.6.0 - 2020-12-10

Added

• Support for 16-bit words with SPI (#107)
• SPI support for reclock after initialization (#98)
• Support for stm32f302x6 and stm32f302x8 devices (#132)
• Support for the onboard real-time clock (RTC) (#136)
• Enable DMA for USART on stm32f302 devices (#139)
• Basic CAN bus support (#100)
• Impls for all SPI pins for all stm32f302 sub-targets, stm32f303 subtargets, stm32f3x8 targets, stm32f334, and stm32f373 (#99)
• SPI4 peripheral for supported devices. (#99)
• Support for I2C transfer of more than 255 bytes, and 0 byte write (#154)
• Support for HSE bypass and CSS (#156)
• Impls for missing I2C pin definitions (#164)
• Support I2C3 (#164)
• Support for defmt (#172)
  • Now defmt features are available.
  • Currently these are only used for panicking calls, like assert! panic! or unwrap(). These are enabled using the defmt filter.
  • For now defmt is mostly intended for internal development and testing to further reduce panicking calls in this crate. The support of this feature is subject to change as the development of defmt is advancing.

Changed

• Introduced auto-generated GPIO mappings based on the STM32CubeMX database (#129)

Fixed

• Fixed #151 not being able to generate 72 MHz HCLK for stm32f303xc devices (#152)
• Wrong I2C clock source (#164)

Breaking Changes

• Removed impl for SckPin<SPI2> for PB13<AF5> from stm32f328 and stm32f378 targets. (#99)
• Removed SPI1 support for stm32f302x6 and stm32f302x8 sub-targets and stm32f318 target. (#99)
• This release requires 1.48, as intra-doc-links are now used internally. Until now, no MSRV was tracked. This has changed now. This however does not mean, that we guarantee any MSRV policy. It is rather for documentation purposes and if a new useful feature arises, we will increase the MSRV. (#170)
• Removed I2C2 support for stm32f303x6, stm32f303x8 and stm32f328 targets. (#164)
• I2c::i2c1 and I2c::i2c2 functions are renamed to I2c::new. (#164)

v0.5.0 - 2020-07-21

Added

• Implement InputPin for Output<OpenDrain> pins (#114)
• Support for safe one-shot DMA transfers (#86)
• DMA support for serial reception and transmission (#86)
• ADC support for stm32f303 devices (#47)

Fixed

• PLL was calculated wrong for devices, which do not divide HSI (#67)

Changed

• The system clock calculation is more fine grained now. (#67) Now the system clock can be some value, like 14 MHz, which can not a be represented as a multiple of the oscillator clock:

let clocks = rcc
    .cfgr
    .use_hse(8.mhz())
    .sysclk(14.mhz())

// or
let clocks = rcc
    .cfgr
    .use_hse(32.mhz())
    .sysclk(72.mhz())

This is possible through utilizing the divider, which can divide the external oscillator clock on most devices. Some devices have even the possibility to divide the internal oscillator clock.

Breaking changes

• The feature gate requires you to select a subvariant if possible. (#75)
• Split up stm32f302 into sub-targets stm32f302xb,stm32f302xc,stm32f302xd,stm32f302xe
• Bump stm32f3 dependency to 0.11.0 (#97)
• The stm32f3 reexport is now renamed from stm32 to pac (#101)
• The correct stm32f3 modules are now used for the stm32f318 and stm32f738 targets. As a result, some previously (wrongly) supported peripherals have been removed from these targets. (#116)

v0.4.3 - 2020-04-11

Added

• Independent Watchdog (#58)

Fixed

• Wrong default modes for debug GPIO pins (#82)
• Wrong calculation of HCLK prescaler, if using a prescaler value equal or higher than 64 (#42)
• UART reception error flags not cleared (#91)

v0.4.2 - 2020-03-21

Fixed

• Wrong frequency reported by MonoTimer (#56)
• Use automatic mode with I2C autoend on Read (#72)

Changed

• Implement blocking Write for UART (#50)
• Implement blocking Read for I2C (#52)

Fixed

• Regression in v0.4.0 that set SPI to LSB-first ordering (#60)

v0.4.0 - 2019-12-27

Added
