Ryo Iizuka / Mbed 2 deprecated mbedJS Featured

This is a Json-RPC/2.0 server with websocket and httpd. You can control mbed(s) by Javascript, processing, Java. LPCXpresso1769/LPC1768/FRDM-K64F/LPC4088

Dependencies:   NyFileSystems libMiMic mbed-rtos mbed

Fork of MiMicRemoteMCU-for-Mbed by Ryo Iizuka

English

MiMicProject http://nyatla.jp/mimic/wp/

This application allow to control the remote mbed through the network. It allows to control the mbed without a firmware update. It has some Interface. There are Javascript(WebBrowser), Procesing, Java. API waits for a function very similar to mbedSDK.

Feature

  • Low delay RPC by Websocket+JSON-RPC.
  • OnChip programing environment (Javascript).
  • Zero configuration support (UPnP/mDNS/AutoIP/DHCP)
  • mbedAPI like APIs.
  • Supports mbed LPC1768/LPCXpresso1769/LPC4088/FRDM-K64F

GettingStarted

mbed(LPC1768)

  • Compile and write mbedJS to your mbed.
  • Create mimic.cfg file to the mbed drive. This is network configuration.
  • Connect to Ethernet cable to the mbed.
  • Reset mbed.
  • Open http://[mbed IP address]/ by web browser.
  • Click JavascriptEditor.
  • Click StartButton. LED will be blinking.

LPCXpresso1769 and LPC4088 QuickStartBoard and FRDM-K64F

Those do not have LocalFileSystem. mbedJS initial IP address is "192.168.0.39". Open this address and click Setup page. You can change ipaddress at here.

Reference

日本語

MiMicProject http://nyatla.jp/mimic/wp/

mbedJSはmbedをWebネットワークにつなぐためのアプリケーションです。 Javascript(ウェブブラウザ)、Processing、Javaから、mbedを操作することができます。 これらはmbedSDKのクラスライブラリとよく似たAPIなので、mbedを知っている方なら簡単に使うことができます。

/media/uploads/nyatla/--_2.png

特徴

  • Websocket+JSONRPCによる低遅延なRPC
  • ワンチップでブラウザ向けの開発環境を提供
  • UPnP/Bonjurによるディスカバりに対応
  • mbedSDKのAPIと同じ構成のAPI
  • mbed LPC1768/LPCXpresso1769/LPC4088/FRDM-K64Fに対応

このアプリケーションはMiMicRemoteMCUとよく似ていますが、JavascriptAPIがより使いやすくなりました。

はじめかた

  • ファームウェアをmbedに書き込みます。
  • 設定ファイルにネットワークに合わせたIPアドレスを指定します。
  • mbedをリセットして、設定したIPアドレスをブラウザで開きます。
  • JavascriptEditorを開きます。
  • Startボタンを押してLEDがチカチカすれば成功です。
