Imagecraft has released the demo version of their ICCV8 C compiler tool for Atmel AVR microcontrollers. The demo version is unlimited for 45 days, and code limited thereafter to 64K, non-commercial use only.
One helpful feature in this IDE is the App Builder. This tool allows for quick setup of peripherals on a number of AVR devices, such as timers, SPI, I/O pins, interrupts, etc.
Check out the description of App Builder from the Atmel Applications Journal. (While written for ICCV6, this description still applies.)

Wow, that’s really useful. I’ve been learning to implement these features manually, and it’s nice to see a lot of the fine details like register names available and tied into the IDE.
It’s also great to see that even the demo version has a full feature set. Most of the chips I use don’t even have 64k of program flash anyway. :D
Also check out Codevision if you’re into AVR’s – also has a very useful facility to do this, along with great support and it’s inexpensive. See http://www.hpinfotech.ro for details.
…… and no I don’t work there, just a happy customer :-)
