We are working on a project where we need the current clock of the Arduino. We have searched and found out that there is a pin in ATMega that is call CLK0, they said that if we put a wire on this one it will take the clock out, but it doesn't. This pin doesn't have anything, it value in the oscilloscope is 0. I also read that it can be done with two arduino together, but how do you connect them and where the clock comes out? If someone could help us we would be very grateful.
You have to change a fuse but to bring the system clock out on the CLK0 pin.
Get yourself a Programmer, this one is $7.77 with free shipping in the US.
Change the needed bit in boards.txt, then Burn Bootloader to change the fuse.
We bought the pololu use avr programmer, we did what you told us but we can't see the clock. Now when we want to load other program in the Arduino it comes out this error: " avrdude: ser_drain(): read error: Device not configured". Do you know what can we do to solve this?
Thank you for reading us!
