rp2040-hal v0.6.1

0.6.1 - 2022-11-30

Changed

• Upgraded dependency on critical-section 0.2 to 0.2.8 - @jannic
  (There is also a dependency on version 1.0.0)
• Remove critical-section impl for version 0.2 - @jannic
  Both 0.2.8 and 1.x use the same symbols internally to implement the
  critical sections, so one impl is sufficient, and having both causes
  compilation errors

[0.6.0] - 2022-08-26

Added

• Documentation Example for the bsp_pin! macro - @hmvp

  Critical-section 0.2 is still supported (ie. a custom-impl is provided, compatible
  with the 1.0.0 implementation), to avoid a breaking change. It will be removed
  later. - @jannic
• Add support for the Interpolator. @fenax

Changed

• Update dev dependencies on cortex-m-rtic to 1.1.2 - @jannic
