1 .. _AVR-System-emulator:
6 Use the executable ``qemu-system-avr`` to emulate a AVR 8 bit based machine.
7 These can have one of the following cores: avr1, avr2, avr25, avr3, avr31,
8 avr35, avr4, avr5, avr51, avr6, avrtiny, xmega2, xmega3, xmega4, xmega5,
11 As for now it supports few Arduino boards for educational and testing purposes.
12 These boards use a ATmega controller, which model is limited to USART & 16-bit
13 timer devices, enough to run FreeRTOS based applications (like

17 Following are examples of possible usages, assuming demo.elf is compiled for
20 - Continuous non interrupted execution::
