yep, i did that and it's working. could the problem be from the attiny chip I bought?
i got the attiny running the blink sketch @ 1MHz using the command -F to bypass the signature and it works. the small issue here is that a delay of 1000 (1 second) corresponds to 0.5ms, 2000 -> 1s. what the hell is going on?
is there any way to get the signature stuff working?
So I unplugged Uno, removed the capacitor, set the board as Arduino Uno, plugged Uno, uploaded the ArduinoISP sketch you provided, everything went fine, unplugged Uno again, connected capacitor, set board as ATtiny85 @ 1MHz (internal osc), plugged Uno, sent the blink sketch and freaking error again......
There are two possibilities... 1. Wiring; 2. Clocking
If you have never successfully changed the fuses (done by "Burn Bootloader") then it cannot be #2.
i bought the attiny85 from ebay and this is the first time i'm doing something with it.
i've read some stuff about clocking but I can't figure it out. i have a spare 32KHz crystal, I tried plugin it in the attiny external crystal pins (from the datasheet) but it didn't work. I know almost nothing about attiny and external crystals and fuses etc...
So please guide me, it must be the clock. My arduino is running the ArduinoISP sketch successfully (it is heartbeating in D9), everything is connect like it should to the attiny and I have a spare 32KHz crystal I can use (no 16MHz nor 20MHz..). What steps should I take using the crystal to get my attiny to work right at 8MHz with internal clock
I've checked the wiring a lot of times and I don't see anything wrong..
EDIT: if you look at the capacitor you can see the stripe on the left side meaning the capacitor is reversed but it's only an illusion from the light and the negative side of the capacitor is connected to the ground
I've already uploaded the Arduino ISP sketch to the arduino Uno with no problems. After doing that the Board is defined as Attiny85 internal 8 MHz clock, programmer is Arduino as ISP.
The blink sketch is loaded and the led port is defined as 1. On the attiny the led is connected to port 0. (I'm doing this because the led was blinking when uploading the sketch and I needed to know if it was the sketch running or some boot stuff -> it was boot stuff).
Now I tested the sketch upload with 2 methods: 1) Just connecting arduino uno and pressing Upload sketch button 2) Connecting arduino uno, holding reset and just when "Binary sketch..." shows in the console I let the reset go.
The two methods return different errors (at least in the video but i'm trying to reproduce it right now with no success).
avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.
I've tried a lot of things, I've read a lot of tutorials but I can't solve this problem.. Help?
