Hallo, I have four atmega32s which need to work in parallel. The need to work as equally as possible. This would mean that they have to be clocked by the same source. Can you give me some ideas how to do this correctly?
Is it possible to output the clock frequency on any of the atmega's pins?
Somewhere I read that MCU have OSC outputs for this purpose, but I can't understand how to do this. I read the datasheet but it didn't help. The atmega32 has TOSC pins but as far as I understood they are used for clocking timer2.
My idea was to use timer1 in CTC mode to output the oscillator frequency divided by 2 and then clock the other mega32 with it. But I don't really like this approach.
PS. I guess you might suggest me to use some clock generator chips, but this is not the point, because I can't place them on my PCB :)
