Which Compiler?

Thanks for the reply.

Not within my capabilities

Oh, but it is! This is what I did...

  • Shutdown Arduino
  • Download WinAVR
  • Install WinAVR (I installed to "C:\WinAVR")
  • Navigate to "{ArduinoRoot}\hardware\tools"
  • There should be an "avr" directory there. Rename it. (e.g. "avr (old)")
  • Create a new "avr" directory
  • Move (or copy) the entire contents of WinAVR ("C:\WinAVR") to the "avr" directory ("{ArduinoRoot}\hardware\tools\avr")
  • Create an "etc" directory under the "avr" directory ("{ArduinoRoot}\hardware\tools\avr\etc")
  • Locate the "avrdude.conf" file in the new avr directory ("{ArduinoRoot}\hardware\tools\avr") (I think it was in "bin")
  • Move "avrdude.conf" to the "etc" directory ("{ArduinoRoot}\hardware\tools\avr\etc")

That's it. Install and move some stuff around. Arduino will use whatever toolset is in the "{ArduinoRoot}\hardware\tools\avr" directory. If you want to go back to the original toolset...

  • Shutdown Arduino
  • Rename the "avr" directory (e.g. rename "avr" to "avr (new)")
  • Rename the old avr directory ("avr (old)") to "avr"

That's it. Just swap the two avr directories.

I have noticed that several times there is a GCC upgrade into a new Arduino release there seems to be some function(s) or library(s) that ends up broken.

That's been my concern. But I don't have much choice. There's a bug in the linker / libraries that makes it difficult (sometimes impossible) to use the full 8K of Flash on ATtiny85 processors.

I think the Arduino developers group is working on a automated testing suite project to make new releases more bug free.

They are.

I sure appreciate the effort they do put into the project.

I do too!
