This script uses the get_tick_count function to accurately time the interval between intervalometer shots. If the interval is set too short, then the images will be acquired as rapidly as the camera can fire them. The script uses the shoot command, which returns control to the script after it is done. It reads the time using the get_tick_count (which returns the time since the camera was turned on, in millisecond (msec) units). It then does a shoot, adds the interval to the last time (to get the next "go-time"), then waits for the next go-time to arrive. --Divalent
