Just an info, for people they won't wait for the new WinAVR Release
AtmanAvr C new version 5.1 is available:
AVR-GCC tool chain (gcc-3.4.4, binutils-2.16.1, avr-libc-1.4.0)
Added support for new devices
[Moderator's note: unlike WinAVR, AtmanAVR is a commercial package.]
Yes, the Atman-IDE is commercial. A license is required after the 30 day evaluation period. But the package comes with up-to-date ACR-GCC binaries, (which are open source). Maybe there is a simple way to make AvrStudio work with the Atman AVR-GCC...???
