redplam 4:5213bee8158e 26 Updated to work with arduino-0008 and to include skip() as of
redplam 4:5213bee8158e 27 2007/07/06. --RJL20
redplam 4:5213bee8158e 28
redplam 4:5213bee8158e 29 Modified to calculate the 8-bit CRC directly, avoiding the need for
redplam 4:5213bee8158e 30 the 256-byte lookup table to be loaded in RAM. Tested in arduino-0010
