Revision:

Parent:

Added adding RPC classes so that new objects can be created ver RPC; ; Not all the classes which were originally supported are still supported and there is an issue with the AnalogIn and AnalogOut so these are not supported here yet

MichaelW 5:56fd0b265aba 25 *
MichaelW 5:56fd0b265aba 26 *This class sets up RPC communication. This allows objects on mbed to be controlled. Objects can be created or existing objects can be used
MichaelW 9:bcc2e05e5da4 27 *
MichaelW 9:bcc2e05e5da4 28 * Substantially updated Jan 2016 to work with the updated RPC system
