Added more definitions, fixed read and write functions

Added some functions for testing purposes (will delete once complete), added definitions so there are no magic numbers in the entire file (ie each number has a purpose given thru a definition), completed write and read functions to be able to communicate with the device better. Further comments and work done on various functions.
