I'd like to generate a clock signal with my mega to drive an external camera sensor. The signal is specified as over 10MHz, so 16MHz should work, but it may be possible to make the sensor work with 8MHz. As I'm just starting out, I don't have a very good understanding of the best way to do this.
What I've learned: seems that changing the "fuse" settings for the chip is one way to get a clock signal to a pin, I believe it's pin 52 on the mega. Another way seems to be to use a timer and put it on any pin, but I couldn't quite make sense of the code I've seen for this or how it works. I've also not seen it used for over 8MHz, don't know if 16 is possible.
Which of these approaches would be easier or better to implement? Is there a good clear example (step-by-step would help) of how to do it? Thanks for reading.
