That bit is easy

In this kind of application I probably only need about a dozen discrete pulse lengths. I'll probably store them in an array and select the array member by scrolling through it with single button per output. Depending on the PIC I'll use I might have an "up" and "down" button. Each flash needs a fire and quench signal, so that is 6 pins, plus the buttons takes me up to 9 (or 12) plus a serial output for an LCD plus a synch signal from the camera.
