This programme Sets a web server using light weigh ip (using Donatien Garnier's server code) which reads a voltage and saves it value in an htm file to be displayed on local page. Server 2 2nd edition Two issues here 1 ) the compiler throws a warning about assignment in RPCHandler.cpp and 2) the local .htm file created on the mbed flash memory is always date stamped with the default date 01/01/2008 11:00
