Loading a file

Building binary files

AVR-Avogadro supports compiled binary files. You can create them using avr-gcc or even Arduino IDE.

Using avr-gcc

Lets build a simple blink application, copy this into a file named blink.c.

#define F_CPU 1000000UL
#include <avr/io.h>
#include <util/delay.h>

int main (void) {
    DDRB |= _BV(DDB0); // Set PORT B0 as output
    while(1) {
        PORTB ^= _BV(PB0); // Toggle PORT B0
        _delay_ms(500);
    }
}

We can compile it with avr-gcc using command line like this

avr-gcc -Wall -mmcu=attiny85 blink.c -o blink.o
avr-objcopy -j .text -j .data -O binary blink.o blink.bin

There are some examples in the examples folder.

Using Arduino ide

With Arduino IDE 1.6.5 or later, you can go to Sketch -> Export compiled library to generate an hex file.

Currently this format is not supported, but can be transformed using command line:

avr-objcopy -I ihex -O binary <file>.hex <file>.bin

Where file is the name of the project
