Changelog

Sourced from stm32f4xx-hal's changelog.

[v0.9.0] - 2021-04-04

Changed

• [breaking-change] Bump rand_core dependency to 0.6.
• [breaking-change] Bump main crate dependencies cortex-m, bare-metal and nb
• [breaking-change] Bump stm32f4 version to 0.13.
• Removing error on I2C bus errors due to errata workaround.
• [breaking-change] Updated synopsys-usb-otg dependency to v0.2.0.
• Cleanups to the Sdio driver, some hw independent functionality moved to the new sdio-host library.
• [breaking-change] Sdio is disabled by default, enable with the sdio feature flag.
• Move SDIO card power handling to its own function.
• [breaking-change] Add a 2 ms delay after changing SDIO card power setting.
• [breaking-change] Changed sdio::{read, write}_block buf argument to &[u8; 512].
• Voltage regulator overdrive is enabled where supported and required for selected HCLK.
• I2C driver updated to detect and clear all error condition flags.
• Allow for skipping an ongoing DMA transfer if not using double buffering.
• Change DMA traits to embedded-dma.
• Use bitbanding during clock enabling and peripheral reset to avoid data races.
• Add missing Write implementation for Serial and implemented better error handling.
• [breaking-change] ADC2 and ADC3 no longer allow access to VREF, VBAT, or the internal temperature measurement (ADC2 and ADC3 do not have an internal connection for these channels)
• Improved Serial baudrate calculation to be correct for higher baudrates or lower PCLKs
• Added SysCfg wrapper to enforce clock enable for SYSCFG
• [breaking-change] gpio::ExtiPin now uses SysCfg wrapper instead of SYSCFG
• Change WriteBuffer + 'static to StaticWriteBufferin the DMA module.
• Fixed a race condition where SPI writes could get stuck in an error state forever (PR #269).
• Implement generics on the serial module.
• Implement generics on the i2c module, not including fast i2c.
• Updated SDIO_D0 pin to PB7 for stm32f411 #277
• Address ST erratum 2.1.13 (DM00037591) #278
• Implement generics on the qei module.
• Bump ssd1306 dev-dependency and cleanup examples

Added

• Reexport PAC as pac for consistency with other crates, consider stm32 virtually deprecated
• Added external interrupt (EXTI) support for output pins
• Added check_interrupt method for GPIO pins
• Basic support for DAC
• Add initial DMA support
• Allow specification of ADC reference voltage in ADC configuraton structure
• Added support for hardware-based CRC32 functionality
• Add MonoTimer and Instant structs for basic time measurement.
• Added support for I2S and SAI clocks
• Added support for canbus with the bxcan crate.#273 The version range is <=0.4, <0.6. (Currently the latest version is 0.5.0) #286
• Added a freeze_unchecked method #231
• Added support for the Real Time Clock (RTC)
• Added option to bypass the HSE oscillator and use a clock input #263
