This is RPC_HTTP Example for using WIZnetInterface
Dependencies: HTTPServer WIZnetInterface mbed-rpc DHT mbed-src
I want to make example which can use mbed RPC library and Python interface so I made this project. This project is led controller and temperature/humidity checker with android application. In brief, This project has function as below.
- Controlling tri-color led in the mbed platform ( On/Off )
- Checking current led status ( It can check led color using TTS(Text to Speech) on Android)
- Checking temperature and humidity information using Android
This example used mbed RPC library to control WIzwiki-W7500 board with Android and Android application is made using kivy library of Python.
Simple Application in Android
I explain how to make android application using kivy library of Python. This android application can control mbed device and get information from mbed device. For implementation and operation this application, you have to have step as below.
