Node to use serial communication with Node-RED MCU

Overview

With this node, you can use Serial communication of MCU.
There are two nodes, Serial in and Serial out.

How to use

0. Build the environment for the Node-RED MCU plugin
1. Install this node
   Add from the "Manage palette" in Node-RED or execute the following command.

cd <directory of where package.json is located>  
npm install <folder_path>  

2. Add the path of manifest.json to node_types.json
   (This step may not be necessary because moddable_manifest has been added to the HTML file.
   If you have any problems, please report them to issue)
   node_types.json is located in the directory:
   ".node-red/node_modules/@ralphwetzel/node-red-mcu-plugin/node-red-mcu"
   On Raspberry Pi:
   

3. Try to build with the Node-RED MCU plugin.
