Hi i've been using arduino uno to program attiny but i get this error message:
avrdude: device signature = 0xff03ff
avrdude main() error: expected signature for ATtiny13 is 1E 90 07
double check chip or use -F to override this check
avrdude done. Thank you.
i tried couple times and i see that device signature is changing to 0xffffff or 0x000000.
Checked every pin and connections with multimeter and everything is allright.
i tried difrent settings but still not working. Attiny have burned bootloader and have my old program in it. I programmed uno with arduinoISP as well.
