I am at my wits end right now. I’m trying to control a strip of WS2812 LED lights via a brand new resin enabled Raspberry Pi 3 B+. The strip is this one: https://www.amazon.com/gp/product/B018X04ES2/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
I have it wired through a logic level converter to bump the Pi output from 3 to 5V. I’m using the rpi_ws218x library to control the LEDs: https://github.com/jgarff/rpi_ws281x.
Things I have already tried:
- Enable INITSYSTEM on
- Removing the snd_bcm2835 module, which is known to conflict with the rpi_ws281x library.
- Added RESIN_HOST_CONFIG_hdmi_drive = 2 and RESIN_HOST_CONFIG_hdmi_group = 1 as suggested in this forum post: How to disable Raspberry Pi 3 on-board sound?
I am using the resin-raspberrypi-node base image because I will be running a nodejs server from the pi to control the lights. Right now I am using the terminal on the dashboard to manually start the strandtest.py example from rpi_ws281x. The program runs, but there is no output to the lights.
Things are wired according to this: https://learn.adafruit.com/neopixels-on-raspberry-pi/wiring
Any assistance would be greatly appreciated.
