HTTP RPC Server mit vordefinierten Objekten
Dependencies: EthernetInterface HttpServer Servo mbed-rtos mbed
Fork of RPCHTTPServerVariable by
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
