Dynamic Frame Controller

//Inputs over Serial COM should be numbers separated by commas and no spaces,
//The first number inputted sets the period in microseconds,
//The second sets the pulse time in microseconds (must be less than 16383)
//The third sets the number of frames that will be looped. Make sure this is one less than MaxFrames (eg. if MaxFrames = 100, number of frames should be 99 max).
//Next, the specific LED Patterns are determined by sets of 5 bytes (0-127).
//IMPORTANT: Make sure in the COM interface to change "No line ending" to "Newline". The newline signals the loop to stop parsing.
