node-red-contrib-mcu-serial
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
- Build the environment for the Node-RED MCU plugin
- 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> 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:
Try to build with the Node-RED MCU plugin.
