node-red-contrib-dmxusbpro

A simple Node-Red driver for Enntec DMX USB PRO.

Pre-requisites

Requires Node-Red

Installation

$ npm i --save node-red-contrib-dmxusbpro

Description

• Sends DMX data through the Enntec DMXUSBPRO device
• Adapted, simplified, hacked from the existing node-dmx package
• requires node-serialport module
• node-red-contrib-dmxusbpro node takes an array of ints (0-255) as input.
• node-red-contrib-dmxusbpro requires the serialport node library. Similarly, the serialport needs to be assigned, COM3, COM4, or /dev/ttyS0, etc
• The DMX starting address is assignable in the object. This shifts where the preset array is stored in the Universe buffer.
• Checkout the example Flow called "DMX Presets with MongoDB2 and DMXUSBPRO node"

Example input

Hi

Is it possible to give an example what should be on the input of the node?
Where can I find the "DMX Presets with MongoDB2 and DMXUSBPRO node" example?

Kind Regards
Floris

Not installing

I'm not able to install it on Node Red running into a Raspberry Pi 4

Install Problems

I have set up a raspberry Pi for use with lightcontrol via node-red.
during installation of this node an error occoured and the installation stoped.
one solution is to downgrade the nodejs version from 12.X to 10.20.1.
After the downgrade the installation of this node was successfully and my node-red flow was working correctly.

Possible to install on Mac?

Trying to install on various Mac's give issues with node-gyp, such as:

gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]

Any chance that this library is even supported on Macs?
