Yet Another SIMulator for AVR

# yasimavr Yet another simulator for Microchip AVR microcontrollers, inspired from simavr

---

_yasimavr_ is a simulator for AVR 8-bits microcontrollers. It is mainly aimed at the Mega0 and Mega1 series (ATmega80x-160x-320x-480x and others) with a possibility to work with the “classic” series. (ATMega48/88/168/328 and others)

It is composed of 2 layers: - a C++ layer for the core API and the various peripheral simulation models - a Python layer to handle the configuration, utilities, data recording, and external components

Compilation

libelf is required to compile the shared libraries.

The python bindings for the C++ librairies are built with the SIP tool from RiverbankComputing (https://www.riverbankcomputing.com)

Thanks

Quite a few ideas in this software - and even big chunks of code - originate from simavr. (https://github.com/buserror/simavr) Big thanks to the simavr authors for this great tool !

Supported IOs

• GPIO

• SPI

• TWI

• USART

Supported Cores (very easy to add new ones!)

• ATMega328

• ATMega 0-series (ATmega808/809/1608/1609/3208/3209/4808/4809)

• more to come…

How to use

_yasimavr_ can be used as a Python package to run a prepared simulation script. (See the examples for how it looks like)

It also supports direct command line run python -m yasimavr [options] [firmware]

For the list of command line options, execute python -m yasimavr -h
