Hi, I was playing around with the internal RC oscillator and prescaler by adding the following code at setup of Blink:
CLKPR = 0x80; // enable system clock prescaler
CLKPR = 0x05; // set system clock prescaler 32
The code worked well. After this, I am not able to upload the any sketch to this attiny85 anymore. This was the message I got:
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?
Does this have something to do with the clock + prescaler? Anyone can help?
