Hi Graynomad,
If you look at the response after mine from scswift, he is quite right, its trivial to sort the servos whenever the angle is updated and then just let the ISR CYcle through a pre sorted table.
The next problem is if you have 20 servos at very similar values, Do you stay blocking in the ISR to set all 20 of them ? What about if each is set to a value 1, 2, 3 or 4 microseconds more than the last ?
Its these boundary cases that will determine if the idea can work.
