SimulAVR: Open-Source AVR Simulator
SimulAVR is an open-source simulator for Atmel AVR microcontrollers. It allows you to develop and test AVR firmware on your computer without needing real hardware.
What is SimulAVR?
SimulAVR is an open-source simulator for Atmel AVR microcontrollers. It enables you to develop, test and debug AVR firmware on your PC without the need for physical AVR hardware.
Some key features of SimulAVR:
- Cycle-accurate simulation of popular AVR chips like ATmega8, ATmega128, ATmega1284 etc.
- Support for simulated I/O devices like LEDs, buttons, UARTs, ADC etc.
- Integrates with AVR development tools like avr-gcc, avrdude and gdb for compiling, programming and debugging firmware
- GUI for visually observing I/O pins, registers and memory contents
- Ability to inject simulated external events like button presses, ADC inputs etc.
- Multiplatform support - runs on Linux, Mac and Windows
SimulAVR enables rapid prototyping and testing of AVR code before eventually deploying it to physical hardware. Its detailed simulation and debugging capabilities make it useful for education as well as professional development of AVR-based designs.
