v0.7.7

What's Changed

• cortex-m v0.7.7: add documentation for critical-section-single-core by @adamgreig in #458

Full Changelog: v0.7.6...v0.7.7

v0.7.6

v0.7.6 - 2022-08-12

• Added critical-section-single-core feature which provides an implementation for the critical-section crate for single-core systems, based on disabling all interrupts. (#448)

v0.7.5

Deprecated

• the ptr() function on all peripherals register blocks in favor of
  the associated constant PTR (#386).

Changed

• The inline-asm feature no longer requires a nightly Rust compiler, but
  does require Rust 1.59 or above.

Fixed

• Fixed singleton!() statics sometimes ending up in .data instead of .bss (#364, #380).
  (Backported from upcoming 0.8 release).

v0.7.4

v0.7.4 - 2021-12-31

Added

• Added support for additional DWT counters (#349)
  • CPI counter
  • Exception overhead counter
  • LSU counter
  • Folded-instruction counter
• Added DWT.set_cycle_count (#347).
• Added support for the Cortex-M7 TCM and cache access control registers.
  There is a feature cm7 to enable access to these (#352).
• Add derives for serde, Hash, and PartialOrd to VectActive behind feature
  gates for host-platform use (#363).
• Support host platforms besides x86_64 (#369).
• Added delay::Delay::with_source, a constructor that lets you specify
  the SysTick clock source (#374).

Fixed

• Fix incorrect AIRCR PRIGROUP mask (#338, #339).
• Fix nightly users of inline-asm breaking now that the asm macro is removed
  from the prelude (#372).

Deprecated

• DWT::get_cycle_count has been deprecated in favor of DWT::cycle_count.
  This change was made for consistency with the C-GETTER convention. (#349)

v0.7.3

[v0.7.3] - 2021-07-03

Fixed

• Fixed compilation for native targets on non-x86 host systems (#336, #337).

Added

• The Delay struct now offers direct delay_us() and delay_ms() methods
  without having to go through the embedded-hal traits (#344).

v0.7.2

Fixed

• Fixed a bug where calling asm::delay() with an argument of 0 or 1 would
  underflow, leading to a very long delay.

v0.6.7

v0.6.7

v0.7.1

Added

• New assembly methods asm::semihosting_syscall, asm::bootstrap, and
  asm::bootload.

Deprecated

• msp::write has been deprecated in favor of asm::bootstrap. It was not
  possible to use msp::write without causing Undefined Behavior, so all
  existing users are encouraged to migrate.

Fixed

• Fixed a bug in asm::delay which could lead to incorrect codegen and
  infinite loops.
• Improved timing guarantees of asm::delay on multiple-issue CPU cores.
• Additional compiler fences added to inline assembly where necessary.
• Fixed DWARF debug information in pre-built assembly binaries.

v0.6.6

Fixed

• Fixed missing ITM reexport on thumbv8m.base targets.

v0.6.5

This release is forwards-compatible with cortex-m 0.7, and depends on and re-exports many types from that version. Both 0.6.5 and 0.7 may co-exist in a build.
