Build the environment for the Node-RED MCU plugin  \n1. Install this node  \nAdd from the \"Manage palette\" in Node-RED or execute the following command.  \n\n```\ncd \u003cdirectory of where package.json is located\u003e  \nnpm install \u003cfolder_path\u003e  \n```\n\n2. Add the path of manifest.json to node_types.json  \n(This step may not be necessary because moddable_manifest has been added to the HTML file.  \nIf you have any problems, please report them to issue)  \nnode_types.json is located in the directory:  \n\".node-red/node_modules/@ralphwetzel/node-red-mcu-plugin/node-red-mcu\"  \nOn Raspberry Pi:  \n![node_types.json](./image/node_types.json.png)  \n\n3. Try to build with the Node-RED MCU plugin.\n\n## Test case\n\nOn Raspberry Pi 400, Windows  \n\n- Moddable Two \u0026 ESP32\n- TX: 17\n- RX: 16\n- Port: 2\n- Baud: 115200\n\n and  \n\n- TX: 32\n- RX: 33\n- Port: 1\n- Baud: 115200\n\n![node_edit](./image/node_edit.png)  \n\nWiring:  \n![moddable_two](./image/sample_moddable_two.jpg)  \n![esp32](./image/sample_esp32.jpg)  \n\nSample flows are in the examples folder.  \nFlow on MCU:  \n![flow_serial](./image/flow_serial.png)  \nFlow on Raspberry Pi:  \n![flow_serial_pc](./image/flow_serial_pc.png)  \nSupport for multiple node and port.  \n![flow_serial_multiple_port](./image/flow_serial_multiple_port.jpg)  \n\n## Acknowledgements\n\nThanks to [NW-Lab](https://github.com/NW-Lab) and [mshioji](https://github.com/mshioji) for testing use of Serial with function node.  \n\n[@NWLab](https://qiita.com/NWLab):「Node-RED MCUでFunction Nodeを使ったSerial通信をやってみる」  \n\u003chttps://qiita.com/NWLab/items/5360eff7b8e2685e925a\u003e  \n\n[@mshioji](https://qiita.com/mshioji):\"Try Serial Communication with Function Node in Node-RED MCU\"  \n\u003chttps://qiita.com/mshioji/items/98f2ded0481ce3b5d775\u003e  \n\nIn Japanese:「Node-RED MCU EditionでSerialを使う」  \n\u003chttps://qiita.com/mshioji/items/a750a5d713ab4d54c4cf\u003e  \n\n## Other Links\n\n@ralphwetzel/node-red-mcu-plugin  \n\u003chttps://flows.nodered.org/node/@ralphwetzel/node-red-mcu-plugin\u003e  \n\n@Moddable-OpenSource/moddable  \n\u003chttps://github.com/Moddable-OpenSource/moddable\u003e  \n\nNode-RED User Group Japan:「ノードの開発」  \n\u003chttps://nodered.jp/docs/creating-nodes/\u003e  \n\n[@kazuhitoyokoi](https://qiita.com/kazuhitoyokoi):「Node-REDのノードをつくる手順」  \n\u003chttps://qiita.com/kazuhitoyokoi/items/64ed5b7798197bb6dfdf\u003e  \n\nmy article:Creating a servo node that imports an external class  \n「Node-RED MCU用のノードを作成してみる　その２（Servoノード）」  \n\u003chttps://404background.com/program/node-create-2/\u003e  \n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F404background%2Fnode-red-contrib-mcu-serial","html_url":"https://awesome.ecosyste.ms/projects/github.com%2F404background%2Fnode-red-contrib-mcu-serial","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F404background%2Fnode-red-contrib-mcu-serial/lists"}
