AVR emulator
This program emulates an 8-bit AVR microcontroller. It supports the trivial C "Hello World!" program.
NOTE: This emulator isn't quite complete. One notable thing is that not all status register updates are implemented for all instructions (#2).
Given some C++ source.
#include <avr/io.h>
#include <util/delay.h>
int main() {
DDRB |= _BV(PB6);
for(uint8_t i=0; i<5; i++) {
PORTB |= _BV(PB6);
_delay_ms(500);
PORTB &= ~_BV(PB6);
_delay_ms(500);
}
return 0;
}
