Changelog

Sourced from rppal's changelog.

0.13.1 (October 28, 2021)

• DeviceInfo: Add device identification support for Raspberry Pi Compute Module 4 models with 4GB and 8GB RAM.
• DeviceInfo: Add device identification support for Raspberry Pi Zero 2 W.

0.13.0 (September 27, 2021)

• Add support for embedded-hal v1.0.0-alpha.5 (contributed by @​reitermarkus).
• Gpio: Add into_output_low() and into_output_high() to Pin to set the logic level before changing the pin mode.
• Gpio: Implement From<u8> trait for Level, where 0 is converted into Level::Low, and any other value into Level::High.

0.12.0 (April 17, 2021)

• (Breaking change) Require rustc v1.45.0 or newer to compile the library due to std API stabilizations.
• DeviceInfo: (Breaking change) Replace manual non-exhaustive pattern implementations for Model and SoC with #[non_exhaustive].
• DeviceInfo: Add device identification support for Raspberry Pi 4 B v1.2, Raspberry Pi 400 and Raspberry Pi Compute Module 4.
• Gpio: Fix built-in pull-up/pull-down resistor support for Raspberry Pi 4 B (contributed by @​Dragonrun1).
• Gpio: Add BCM2711 ioctl support (contributed by @​foxzool).
• Hal: (Breaking change) Upgrade embedded-hal trait implementations for digital::v1::{InputPin, OutputPin, StatefulOutputPin, ToggleableOutputPin} to digital::v2. These can be explicitly converted back to digital::v1 through digital::v1_compat::{OldInputPin, OldOutputPin} for backwards compatibility with older drivers.
• I2c: Accept slave addresses below 0x08 (contributed by @​Majkl578).
• I2c: Add documentation for I2C3, I2C4, I2C5 and I2C6.
• Pwm: Improve error messages (contributed by @​binarybana).
• Pwm: Improve documentation for Ubuntu (contributed by @​binarybana).
• Spi: (Breaking change) Add support for SPI3, SPI4, SPI5 and SPI6.

0.11.3 (June 24, 2019)

• DeviceInfo: Add device identification support for Raspberry Pi 4 B. (Support for the new peripherals will be added in 0.12.0)

0.11.2 (May 2, 2019)

• Add hal-unproven feature flag (disabled by default), which enables unproven embedded-hal trait implementations. Note that embedded-hal's unproven traits don't follow semver rules. Patch releases may introduce breaking changes.
• Gpio: Implement Sync trait for IoPin and OutputPin.
• Gpio: Implement unproven embedded-hal trait digital::InputPin for Pin, InputPin, OutputPin and IoPin.
• Gpio: Implement unproven embedded-hal traits digital::{StatefulOutputPin, ToggleableOutputPin} and Pwm for OutputPin and IoPin.
• Gpio: Remove internal MSG_WAITING flag from software PWM implementation to resolve an issue found in the wild causing delays in message processing (contributed by @​aehmlo).
• Hal: Add hal module, containing embedded-hal trait implementations that aren't tied to a specific peripheral.
• Hal: Implement embedded-hal traits blocking::delay::{DelayMs, DelayUs} for Delay.
• Hal: Implement embedded-hal trait timer::CountDown for Timer (contributed by @​jacobrosenthal).
• Pwm: Implement Display trait for Channel and Polarity.
• Pwm: Implement unproven embedded-hal trait Pwm for Pwm.
• Spi: Implement Display trait for BitOrder, Bus, Mode, Polarity and SlaveSelect.
• Spi: Remove From<Error> implementation due to a conflict with nb v0.1.2 (contributed by @​gferon).
• Uart: Add support for the PL011 and mini UART peripherals, USB to serial adapters, XON/XOFF software flow control and RTS/CTS hardware flow control.
• Uart: Implement embedded-hal traits serial::{Read, Write} and blocking::serial::Write for Uart.

0.11.1 (February 24, 2019)

• Fix incorrect data type conversion on 64-bit OSes when libc uses 64-bit timespec fields.
