libMiMic(MiMic library for mbed)は、WebService機能を提供するSDKです。 mbedでWebAPIに対応したネットワークデバイスを簡単に作ることが出来ます。
libMiMicはMiMic projectで開発しています。MiMic projectについてはこちらをご覧ください。 http://nyatla.jp/mimic/wp/
構成
libMiMicはmbedRTOS上で動作し、ユーザアプリケーションにAPIを提供します。コアAPIはC言語で記述されていますが、使用頻度の高いものについてはmbed向けのC++APIが準備されています。
※libMiMicはmbedの標準イーサネットドライバをしようしていません。
標準イーサネットドライバと同時に使用することはできません。
- MiMicIP - IPv4スタックです。レテンシとメモリ消費量を抑えたuipベースのライブラリです。
- ARP/ICMP/UDP/TCP - 基礎的なソケットAPIを提供します。APIは独自です。
- HTTP/1.1 Server - HTTP/1.1に対応したサーバです。マルチセッション・Chunked・持続性接続に対応しています。
- HTTP Modules - HTTP/1.1の機能モジュールです。以下のモジュールがあります。
- ROM file provider - ROMに格納したファイルイメージを公開します。
- File system provider - mbedファイルシステムを公開します。
- Onchip configuration - プログラムフラッシュを利用して設定を保存します。
- MiMicVM processor - RPCリクエスト(MiMicVM)を処理します。
- FileUpload - ファイルアップロードを受け取ります。
- URL decoder - HTTPリクエストを解析します。
- UPnP handler -UPnPメッセージを処理します。
- WebSocket - Websocketサーバです。
- mDNS - マルチキャストDNSサービスです。
- UPnP - UPnP/1.0の機能を提供します。UPnP handlerと協調して動作します。(現在はデバイス探索(SSDP)・デスクリプション(Description)のみ実装してあります。)
- DHCP/APIPA - ゼロコンフィギュレーション用のモジュールです。
- HTTP/1.1 Client
- mbed C++ class library - mbed向けのC++CPIです。C言語のものより簡単です。
対応機種
- mbed(mbed LPC1768)
- LPCXpresso1769
プログラム
Import programMiMicRemoteMCU-for-Mbed

English
libMiMic(MiMic library for mbed) is SDK which provides Webservice functions. It can be created networking device easily using mbed.
See more MiMic information, See MiMic project website. http://nyatla.jp/mimic/wp/
Structure
libMiMic run on mbed RTOS and provides networking API to user application. This library has C++ class API for the mbed, and low-level C language API.
For WebService general, it can be written in a simple C + + API.
libMiMic does not have the standard Ethernet driver of mbed. It is not possible that will be used with the standard Ethernet driver.
- MiMicIP - IPv4 protocol stack. This is based uip which is reduced memory and latency.
- ARP / ICMP / UDP / TCP - Those are provide basic IP protocols.
- HTTP/1.1 Server - The Http server compatible HTTP/1.1. It supports multi-session, chunked transport, persistent connection.
- HTTP Modules - There are addon-module for HTTP server. The following modules.
- ROM file module - Publish the file images in ROM.
- File system module - Publish thefiles in mbed file system.
- Onchip configuration module - To save the network settings to the program flash via REST.
- MiMicVM module - To handle the (MiMicVM) RPC request.
- FileUpload module - Accept a file via HTTP POST.
- URL dedoce module - A versatility URL decoder.
- UPnP handle module - To handle UPnP messages.
- UPnP - This provides UPnP/1.0 device functions. It works together with UPnP handler.
- Websocket - websocket (version13) server
- mDNS Service - DNS-SD protocol server.
- UPnP - This provides UPnP/1.0 device functions which works with UPnP handler. (You have been implemented (SSDP) ? description only (Description) device search now.) It is a module zero configuration for - DHCP / APIPA. mbed C + + class library - C of mbed for + + is the CPI. It is simple than that of the C language.
- DHCP/APIPA - It support zero-cpnfigulation.
- mbed C++ class library. Almost APIs for Web applications are available.
- HTTP/1.1 Client
Supported target
- mbed(mbed LPC1768)
- LPCXpresso1769
