#
# 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, ..., bit n (1 to 9)
#
# Sample usage which generates 5 frames:
#
# ./param2HexFrame.pl "25;3,2,5,8;" "14;3,3,5,7" "3;3,4,5,6;2,6,5,4" "23;3,1,5,9" "0;2,1,2,3,4,5,6,7,8,9;1,5"
# Frame 0 = 0xca480000 = hi:0xca48 = lo:0x0000 = 0b11001010010010000000000000000000
# Frame 1 = 0x71500000 = hi:0x7150 = lo:0x0000 = 0b01110001010100000000000000000000
# Frame 2 = 0x18e07000 = hi:0x18e0 = lo:0x7000 = 0b00011000111000000111000000000000
# Frame 3 = 0xbc440000 = hi:0xbc44 = lo:0x0000 = 0b10111100010001000000000000000000
