Unreleased

0.5.0 - 2022-06-13

MSRV

The Minimum-Supported Rust Version (MSRV) for this release is 1.61

Added

• RP2040 specific #[entry] macro that releases spinlocks - @jannic
• Start multiple state machines in sync with each other - @astraw
• Unsafe fn for freeing all spinlocks when you can't use the RP2040 entry macro (eg RTIC) - @9names
• Optional feature for enabling defmt formatting for i2c errors - @ithinuel
• Accessor for getting the offset of an installed PIO program - @fenax

Changed

• Use thread send safe UART* marker when splitting, improves UART ergonmics - @marius-meissner
• Improve performance for hardware division instrinsics. Internal intrinsics cleanup - @Sizurka
• Provide a better alarm abstraction - @ithinuel
• Update Multicore::spawn to be able to take a closure without requiring alloc. Improve Multicore ergonomics and add example for how to use new API - @Liamolucko
• Allow PIO program to be 32 instructions long, was previously limited to 31 - @jannic
• Fix Typos - @mqy, @danbev
• Replace generic pio::Tx::write with write_u8_replicated, write_u16_replicated, and update write to take a u32. The generic version was too easy to misuse. - @9names

Removed

• I2c async driver. Use new one at https://github.com/ithinuel/rp2040-async-i2c/ - @ithinuel
• Unused fields from UartPeripheral and Reader - @jannic

0.4.0 - 2022-03-09

Added

• ROM function caching
• ROM version lookup function
• Compiler intrinsics for ROM functions
• Compiler intrinsics for hardware divider
• Document bsp_pins! macro
• UART IRQ examples
• PIO side-set example
• Stopped PIO state machines can change their clock divider
• Added HAL IRQ example

Changed

• Rewrite UART driver to own its pins
• Improve UART defaults
• Fix repeated-read in i2c embassy driver
• Fix bug in i2c peripheral state machine
• Fix race condition in alarm
• Fix safety bugs in hardware divider
• Enable watchdog reset trigger bits when watchdog enabled
• Update spinlocks to use new PAC API
• Use generics to improve spinlock implementation
• Update critical_section to use new spinlock implementation
• Update embedded-hal alpha support to version 1.0.0-alpha.7
• Avoid 64-bit division in clock calculations
• Update pio and pio-proc to 0.2.0
