Description

Which node are you reporting an issue on?

node-red-node-pi-neopixel

What are the steps to reproduce?

use docker image braghettos/makealedwheaterboard:latest
source code is available at https://github.com/braghettos/makealedweatherboard.git

What happens?

Every time node-red starts, the rainbow test is started. When the rainbow test ends, the last leds remain switched on with different colors. I have 840 leds.

What do you expect to happen?

Leds cleared on startup.

Please tell us about your environment:
  • Node-RED version: nodered/node-red:1.0.4-12-minimal-arm32v6
  • node.js version: Node.js version: v12.16.1
  • npm version: 6.13.4
  • Platform/OS: Linux 4.19.97+ arm LE (Alpine)
  • Browser: Version 80.0.3987.132 (official Build) (64 bit)

Research direction

Start by inspecting the node-red-node-pi-neopixel implementation and reproduce the startup behavior with the linked Docker image and makealedweatherboard project. Check the rainbow test's cleanup for a 840-LED setup; done means every LED is cleared when the startup test ends.
