Hi all, I really appreciate your help, please dont let my request unanswered!
I know they are some other related discussions, but it has not helped me.
Problem description: I want to program a Attiny 45 and also Attiny85 through an arduino Nano. The wicked thing is that I had already succeeded in doing this two weeks ago, now I can't get it to work.
I am using the instructions from this tutorials [http://www.instructables.com/id/Attiny-Programmer-using-Arduino-UNO/[/url
or from here: http://highlowtech.org/?p=1695
I checked the pin and cables many times and have built it with different configurations and it is not the reason of the problem. I also tried with an arduino nano and arduino mega.
I tried with different ATtiny 45 or Attiny85 - same results for all.
I am really following the instructions, loading the ArduinoISP program into the nano, then attaching a 1uF or 10uF Capacitor between RST and GND and changing the board configuration to ATtiny85, 1MHz, Arduino as ISP
I have even followed one of the forum discussion suggestions to attach a 110 Ohm resistance (100 + 10) between 5V and RST.
I am getting this error message in arduino IDE:
Sketch uses 678 bytes (8%) of program storage space. Maximum is 8192 bytes. Global variables use 9 bytes (1%) of dynamic memory, leaving 503 bytes for local variables. Maximum is 512 bytes. avrdude: Expected signature for ATtiny85 is 1E 93 0B * Double check chip, or use -F to override this check.* Wrong microcontroller found. Did you select the right board from the Tools > Board menu?
what I am doing wrong? what can I change. I even tried to double check the signatures from the ATtiny datasheet and correlated them with the avrdude.conf
I have not yet tried to load it through the terminal with avrdude and -F ( overriding invalid signature check). but as I wrote earlier, it worked out without it last time.
1000x Thanks in advance!
