I am trying to connect my atmel atmega8 with usbasp (V0.2) to my PC. I follow [this tutorial][1] to connect my atmega to usbasp. I have a 6-pins connector: o MISO o VCC o SCK o MOSI o RESET o GND Once I connect my usb to my PC, led turns on, and in Control Panel (win7) I see "libusb-win32 devices". After having compiled main.c with winAVR "make" command, if I try to use "make program" command or I write in cmd this: avrdude -p atmega8 -P m8 -c usbasp -U flash:w:main.hex system tells me: avrdude: error: programm enable: target doesn't answer. 1 avrdude: initialization failed, rc=-1 Double check connection and try again, or use -F to override this check How can I solve this problem?
