Node-RED Jacdac Node
Node-RED nodes to talk to Jacdac.
Jacdac is a bus-based plug-and-play hardware and software stack for microcontrollers and their peripherals. Jacdac is primarily designed for “modular electronics” scenarios that support rapid prototyping, creative exploration, making and learning through physical computing. Jacdac is designed to be cheap, flexible and extensible.
The nodes connect to a Jacdac bus via a USB and allow to listen for events or sensor readings.
Install
Use Palette manager in node-red or run the following command in your Node-RED user directory - typically ~/.node-red
npm install node-red-contrib-jacdac
Jacdac hardware
In order to connect to Jacdac modules, you will need to connect to a USB module or a SPI bridge.
Nodes
jacdac-event
This node listens for Jacdac events and send them in the payload. You can browse the services specification catalog to discover which events are available.
jacdac-report
This node reads Jacdac registers and send them in the payload. You can browse the services specification catalog to discover which registers are avilable are available.
By default, the node looks for sensor reading, value and intensity registers. But you can override this behavior by customizing the register filters by name or code.
jacdac-command
This node sends Jacdac commands to services. The results of command can be inferred from the content of the registers.
You can browse the services specification catalog to discover which commands are available and how their payload should be formatted. The payload can either be a number, string or boolean for simple t ypes. Or an array or JSON object for complex requests.
Acknoledgments
This repo was built using the node-red TypeScript starter.
