AVR C compiler

Accueil Welcome


Un compilateur C très complet pour les microcontroleurs "AVR" d'Atmel.
Il est fourni avec un IDE, des wizards (utile pour démarrer une application), un optimiseur de code, ...

32 bit application, runs under Windows 95, 98, NT 4.0 and 2000

Easy to use Integrated Development Environment and C Compiler

Editor with auto indentation and keywords highlighting

Supported data types: bit, char, int, short, long, float, double

AVR specific extensions for:

Accessing the EEPROM & FLASH memory areas

Bit level access to I/O registers

Interrupt support

Compiler optimizations:

Peep-hole optimizer

Advanced variables to register allocator, allows very efficient use of the AVR architecture

Common Block Soubroutine Packing, replaces repetitive code sequences with calls to subroutines

Loop optimization

Branch optimization

Subroutine call optimization

Constant folding

Store-copy optimization

Two memory models: TINY (8 bit data pointers for chips with up to 256 bytes of RAM) and SMALL (16 bit data pointers for chips with more than 256 bytes of RAM) for better code efficiency

User selectable optimization for Size or Speed

Possibility to insert assembler code directly in the C source file

VERY EFFICIENT USE OF RAM: Constant character strings are stored only in FLASH memory and aren't copied to RAM, like in other compilers for the AVR 
C Source level debugging, with COFF symbol file generation, allows variable watching and the use of the Terminal I/O in Atmel’s AVR Studio 3.2 Debugger 
Fully compatible with Atmel’s ICE200 In-Circuit Emulator
