→avec l'AVRISP V2
<code lang:bash>AVRDUDE = avrdude -c avrisp2 -P usb -p $(DEVICE)</code>
ensuite on lance la compilation :
<code lang:bash>make hex</code>
le résultat de la compilation :
<code lang:bash>avr-gcc -Wall -Os -DF_CPU=20000000 -Iusbdrv -I. -DDEBUG_LEVEL=0 -mmcu=attiny44 -c usbdrv/usbdrv.c -o usbdrv/usbdrv.o

Puis on regle les fusibles :
<code lang:bash>make fuse</code>
résultat :
<code lang:bash>avrdude -c avrisp2 -P usb -p attiny44 -U hfuse:w:0xDF:m -U lfuse:w:0xFF:m

enfin, on upload le programme :
<code lang:bash>make program</code>
résultat :

Le programmateur est maintenant prêt à fonctionner : il ne reste plus qu'à dessouder les juppers 1 et 2.
Pour férifier qu'il réagit bien, je tape
<code lang:bash>lsusb</code>
Lorsque j'ai branché le programmateur, il apparait dans la liste sosu cette forme :
<code lang:bash>Bus 003 Device 013: ID 1781:0c9f Multiple Vendors USBtiny</code>
ça y est, j'ai un FabISP qui fonctionne !
