# usage: 
#
#   ./param2HexFrame.pl "frame 1 data" "frame 2 data" ... "frame N data"
#
#   frame X data = delay; layer 1; layer 2; layer 3
#
#   delay = 0 to 31 (multiplied by 8 in firmware and equals to the ISR calls (delay/300 seconds)
#           0 equals to a delay of 255/300 seconds.
#
#   layer Y = layer no(1,2,3), bit0, bit1, bit2, ..., bit8 (bitN = 1 ... 9)
#
# Sample usage which generates 5 frames:
