What I do, is to set up an array of bytes in memory, each holding a
0-255 value for pulse width.
I add this to a minimum pulse width, and create timer values.

I start all the servo pulses at once, then turn them off at the
appropriate time using a single timer interrupt.

So the output looks like

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

and so on.

Then the framing pulse (15mS or so) is just a do-nothing time.
