Fixed

• Fixed undefined behavior in SPI full duplex RX DMA transfers.

Added

• Added rcc::Lsco to use the low-speed oscillator output.
• Added Rtc::calibrate_lp to calibrate the RTC.
• Added Rtc::recalibration_pending.
• Added Rtc::is_alarm_{a,b}_en.
• Added methods to utilize ADC oversampling.

Changed

• Rtc.alarm_{a,b} returns Alarm instead of Option<Alarm>.
• Updated stm32-rs from 0.14.0 to 0.15.1.

Fixed

• Fixed a documentation bug in rtc::Alarm. Values are masked if true, but the documentation indicated they are masked if false.

Added

• Added Rtc::alarm_{a,b} to get the alarm value.
• Added impl From<Alarm> for chrono::NaiveTime.
• Added RfSwitch::steal() to all BSPs.

Added

• Added set_sleep_clock to GPIO ports to enable and disable clocks during sleep.
• Added subghz::Timeout::saturating_add.
• Added SubGhz.set_rtc_period and SubGhz.restart_rtc methods required to workaround an erratum with SubGhz.set_rx_duty_cycle.
• Added SubGhz.new_no_reset and SubGhz.new_with_dma_no_reset to create a SubGhz without resetting the radio.

Changed

• Changed minimum supported rust version from 1.57 to 1.60.

Fixed

• Fixed a typo in the Exti::set_falling_trigger function name.
• Fixed endianness in SubGhz.op_error.

Added

• Implement embedded_hal::PwmPin for LpTim.

Changed

• Inlined trivial Rng methods.

Fixed

• Fixed UART clock_hz methods returning the wrong frequency.

Added

• Added a is_pending method to the gpio::Exti trait.
• Added alarm functionality to the RTC.
• Added Rtc.is_wakeup_timer_en.
• Added flash::flash_range.
• Added Flash.program_bytes for safer flash programming.

Changed

• Replaced Debug implementation with Display implementation for:
  • subghz::FskPacketStatus
  • subghz::LoRaPacketStatus
  • subghz::Stats
  • subghz::Status
• Flash::standard_program_generic now checks for overflow.

Fixed

• Fixed an off-by-one error in flash::Page::addr_range.

Removed

• Removed util::reset_cycle_count; this functionality is now in cortex-m.

Added

• Added info::Core::CT to get the CPU core at compile time.
• Added info::Core::from_cpuid() to get the CPU core at runtime.
• Added a flash module with erase and program functionality.
• Added defmt::Format for all types declared in the BSPs.
• Added info::uid::PTR.

Changed

• Changed minimum rust version from 1.56 to 1.57 for const_panic.
• info::UID64
  • Moved to info::Uid64::PTR.
  • Changed the type from *const u8 to *const u32.
• Moved functions in info into the associated structs/enums.
  • Moved info::uid64 to info::Uid64::from_device.
  • Moved info::uid64_devnum to info::Uid64::read_devnum.
  • Moved info::package to info::Package::from_device.
  • Moved info::uid to info::Uid::from_device.
• Added #[inline] to util::new_delay and util::reset_cycle_count.
• Large dependencies are now optional.
  • embedded-time is now an optional feature.
    • Changed I2C::new to use u32 instead of embedded_time::Hertz.
  • chrono is now an optional feature.

Fixed

• Fixed timeouts after calling SubGhz::set_sleep.

Added

• Added two board support crates
  • nucleo-wl55jc-bsp
  • lora-e5-bsp

Changed

• Crate ownership changed from tweedegolf to stm32-rs.
  • Thank you tweedegolf for the initial development effort!
• Sweeping changes throughout the entire crate, nothing is the same.
