Timer Interrupts on Due

@selfonlypath: Very impressive - well done!

@WomensFashionArt:

WomensFashionArt:
No can do with the sync I'm afraid, there's 20m of cables between them and all sync is being done over this cable. I'm pretty sure that we'll end up using an interrupt of some sort so that all of them are able to reset at exactly the same time.

... the Due can't handle the logic at the requisite 1,000,000 interrupts / second

Couple of queries:

  • How well synchronized do the different Dues have to be? 10 us, 1 ms, 1s ?

  • And how did you get the 1 MHz figure? Is it from the precision you want for each part of the PWM cycle?

Best,
Jim
