    @mharsch/node-red-serlcd

    A Node-RED node for communicating with Sparkfun SerLCD boards

    Pre-requisite

    Follow Sparkfun instructions for installing the Qwiic_SerLCD_Py Python package. If you need to change the i2c address (which is persistent), use the python interface. Try out the hello world from python first to make sure the display is working before moving on to this Node-RED node (as we use the python under the hood).

    Install

    Either use the Node-RED Menu - Manage Palette option to install, or run the following command in your Node-RED user directory - typically ~/.node-red

    npm install @mharsch/node-red-serlcd
    

    Usage

    Send a string to the node to display on the LCD display. This node follows the interface specified by node-red-node-pilcd e.g. send "clr:" to clear screen. See example flow in this repo for extensions to the interface including "contrast:" and "backlight:".

    Install

    npm i @mharsch/node-red-serlcd
