flAVR is a simulator for the Atmel(tm) AVR(tm) microcontrollers written in C.

The project aims to implement a cycle-accurate AVR CPU core simulator along with a range of peripherals, allowing firmware written for a variety of parts to be run on a host PC.

In addition, flAVR provides enhanced interactive debugging functionality - featuring breakpoints, data watchpoints, execution tracebuffers, flash/RAM/EEPROM viewers, and run-time disassembler.

flAVR also implements the GDB remote protocol, allowing it to interface with Eclipse and other IDEs supporting GDB.

The simulator also supports kernel-aware co-simulation when running binaries linked with the Mark3 RTOS, providing it with virtual input and graphics devices.

The project is designed to be highly-portable, and builds with minimal dependencies.

Currently, flAVR builds have are targeted to Windows (MinGW) and Linux (GCC).
