http://www.microcontroller.com/news/Atmel_AVR_Studio_5.asp The feature looks quite good. Now it is using a unified IDE for the AVR and AVR32. The current AVR32Studio is using Eclipse based IDE and runs under Linux/Windows. "Features of the new Atmel AVR Studio 5 include: * Visual Studio Editor * Support for all Atmel tinyAVR, megaAVR, AVR, XMEGA, and AVR UC3 microcontrollers * C/C++ compiler * Assembler * Linker * Debugger & Simulator * Support for target board debugging via JTAG or PDI (Program Debug Interface)" Their reason of not using Eclipse is quite interesting. "All of Atmel's future development environments will be based upon the AVR Studio IDE. Atmel will no longer support Eclipse-based IDEs or editors. As Eclipse is more geared towards desktop PC software development, Eclipse has not proven itself as efficient or effective as a dedicated embedded development IDE such as AVR Studio." The downside of using Visual Studio interface is the loss of potential support for Mac OS X and Linux. So Atmel is going a detour now. Microchip, on the other hand, has the unified IDE for all PICs all along, but no Linux support last time. Now Microchip is going to support Linux and Mac OS X along with Windows with the new Netbean based MPLAB IDE X. Microchip is still doing quite well now. But Atmel is doing much better than last time. So let's see if this move will affect any thing or not. --=20 Xiaofan --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
