  Hi everyone, avr_io v0.5.0 just got release, alongside with avrman v0.3.0!

  I am continuing to stabilize the implementation of the whole library, while I use it for my projects, and fixing some stuff that got broken with the newest GCCs:

  • The avr_io/progmem module received a big rework, (new implementation, operators, deprecation warnings for old
  • Interrupt Service Routines can now be called with a flag that can modified the ISR attribute to be Block/NoBlock/Naked, reflecting the underlying gcc implementation.
  • Added "atomic" templates in avr_io/interrupt, to execute code blocks with or without interrupts, ensuring re-enable or disabling after the scope is exited.
  • Pin operations are now safer: when used with static integers, they get checked at compile time, at runtime they get masked so they are not out of bounds, if not running with -d:danger, in which case not checks are done.
  • Fixed progmem bindings as part of the GCC 14/15 support effort.

  avrman also got a new and pretty big release, and it now supports devices.

  Devices are either programmers or boards (e.g. arduinos), and the tool has information related to the settings tied to these devices, so that using the tool can become quite easier for end-users.

  This also lead me to write a usb serial device enumeration algorithm to retrieve vid/pids and make it possible to discover these devices, but here's the problem:

  I wrote one for Linux/MacOSX, but I am missing one for windows, so if anyone has the knowledge that I lack there, PRs are more than welcome!

  And I found a small bug/regression while using the library, so here is a super quickly released patch version:
