Version 0.8.0

Changed

• BREAKING: Changed the architecture of avr-device such that code is now generated at build time (#157 by @LuigiPiucco). This allows us to scale better and also makes the code-generation much simpler in general. No external dependencies need to be installed anymore when working on this crate.
• BREAKING: Upgraded to svd2rust version 0.36.1 (#157 by @LuigiPiucco). This leads to mostly one major change in the register API:
  • Registers are now accessed through functions instead of struct members.
    In practice, this means you will have to do the following changes throughout your codebase:

  -dp.PORTD.portd.write(|w| w.pd3().clear_bit());
  +dp.PORTD.portd().write(|w| w.pd3().clear_bit());
  
  -dp.TC0.tccr0b.write(|w| w.cs0().prescale_1024());
  +dp.TC0.tccr0b().write(|w| w.cs0().prescale_1024());

• BREAKING: Renamed the critical-section-impl to just critical-section and enabled it by default. This was done because the Periperals::take() method is now gated on critical-section (#195).
• Switched to the rust version of svdtools (#174 by @tones111).
• Better register definitions for peripherals of the ATmega128RFA1 (#173 by @NikBel3476).

Added

• Support for AT90CAN128, AT90CAN64, and AT90CAN32 (#206 by @alios).
• Support for AVR128DB28 (#207 by @tomtor).
• Support for ATtiny204, ATtiny804, and ATtiny1604 (#182 @nonik0).
• Support for ATtiny1606 (#183 by @hammerlink).
• Support for ATtiny261A, ATtiny461A, and ATtiny861A (#179 by @mbuesch).
• Support for ATtiny417, ATtiny817, ATtiny1617, and ATtiny3217 (#184 by @G33KatWork).
• Support for ATtiny1626 (#185 by @ckoehne). The VPORTA.DIR register is currently unavailable due to a compiler limitation. See pull request for details.
• Added asm::get_stack_size() function which returns the current size of the stack (#189 by @LuigiPiucco). This function depends on the rt feature.
• Added asm::nop2(), asm::nop3(), asm::nop4(), and asm::nop5() functions that delay for precisely 2 to 5 cycles (#228 by @mbuesch). These are useful for precise timing in bit-banging.

Version 0.7.0

Added

• Added support for ATtiny212, ATtiny214. ATtiny412, ATtiny414, ATtiny416 (#167 by @innermatrix).
• Added support for ATmega16U2 and ATmega32U2 (#164 by @zacharytomlinson).
• Added support for ATmega3208 and ATmega3209 (#164 by @zacharytomlinson).

Changed

• BREAKING Upgraded to atdf2svd version 0.5.0 (#170). This is a breaking change because some registers now have fields instead of safe .bits() access. Chech the pull-request for details.
• BREAKING Renamed in to input in ATtiny-xmega PORT registers (#171 by @innermatrix).

Fixed

• Fixed ATmega88P not being available (#166 by @blueberry-fan).

• Added support for ATtiny26 (#158 by @mbuesch).

Changed

• Upgraded to atdf2svd version 0.4.0 (#154).
• The split peripherals of ATmega4808, ATtiny402, ATtiny404 are now represented (#154 and atdf2svd#48).

Fixed

• Patched the ADC registers of ATtiny84A (#151).

Added

• Support for ATtiny44A (#141 by @MichaelDarr).
• Support for ATtiny84A (#143 by @MichaelDarr).
• Added an example of bare avr-device usage (without avr-hal) (#146 by @Frankkkkk).

Fixed

• Added missing pin fields in DDR,PIN,PORT registers for ATtiny167, ATtiny84, ATtiny2313, and ATtiny2313A (#148, #149).

Version 0.5.0

Added

• Support for ATtiny404 (#111 by @agausmann).
• Support for the critical-section crate via a critical-section-impl feature flag (#116).

Changed
