HTTP RPC Server mit vordefinierten Objekten

Dependencies:   EthernetInterface HttpServer Servo mbed-rtos mbed

Fork of RPCHTTPServerVariable by th.iotkit2.ch

Mittels RPCVariable lassen sich lokale Variablen setzen. Diese Variablen können gesetzt write oder gelesen read werden.

Mittels Ticker u.ä. Varianten lassen sich damit auch Objektwerte setzen, welche von RPC nicht unterstützt werden, z.B. Servo's.

Client

Wert setzen: http://<IP-Adresse mbed>/rpc/servo2/write+0.5
