RPC over HTTP example.

Dependencies:   EthernetInterface HTTPServer mbed-rpc mbed-rtos mbed

Fork of RPC_HTTP by Michael Walker

This is a working example of using RPC over HTTP. This uses an ethernet connection. The program attaches an RPC handler to LED1. You can use a client program to send commands to this LED, addressing it as "led1".
