If you only send [0,0,0] frequently, does it becomes RED sometimes ?

Yes.

It`s any possible to rework that? any resistor help?

January 7, 2020

I`m observe that often [0,0,0] (turnoff) is RED.

Update code

But nothing chnage

(however i just lern how to use "" twice Thanks (\" did`t know\" )

import os
import time

White = "/root/Downloads/ws2812-spi/ws2812.py -c \"[[255,255,255]]\" -n 1"
Green = "/root/Downloads/ws2812-spi/ws2812.py -c \"[[0,255,0]]\" -n 1"
Blue =  "/root/Downloads/ws2812-spi/ws2812.py -c \"[[0,0,255]]\" -n 1"
Red = 	"/root/Downloads/ws2812-spi/ws2812.py -c \"[[255,0,0]]\" -n 1"
Off = 	"/root/Downloads/ws2812-spi/ws2812.py -c \"[[0,0,0]]\" -n 1"
y = 0.5

while True:
	
	os.system(White)
	print("white")
	time.sleep(y)
	os.system(Off)
	print("sleep")
	time.sleep(y)
	
	os.system(Blue)
	time.sleep(y)
	os.system(Off)
	time.sleep(y)
	
	os.system(Green)
	time.sleep(y)
	os.system(Off)
	time.sleep(y)

Update, something work but colors is different that should be

back to you first script please check the video the colors is diifren than code (RED is note in Code)

January 6, 2020

I paste the code what You wrote and perform some updates

Unfortunately it`s not work

However

I make some short script like You mentioned before and it`s work but it`s something wrong the RGB LED sometime when should be "off" [(black) (0,0,0)] sometimes shines as RED.

January 6, 2020

I`m really need update script in Python

Do You have idea how to update this script for example to kept the same effect what You wrote ?

What do you mean ?

Do you mean alternating colors within the same script ?

Simply add sleep command between each calls to ws2812.py ...

Yes I know how to generate colors

But won`t work

I don`t know where to paste this script of different colors.

January 5, 2020

I just uninstall python-numpy an color back to normal.

I would like to wrote some short code for change colors in python

Connect the data line of the WS2812B Neopixels to pin SPI1_MOSI/PA15

I Have the OPI WIN not Zero so I connect to SPI1_MOSI/PD2 hope it`s good.

Unfortunately I have error:

Could You advice what I`m doing wrong?

Hello

Ones again I need Your advice for steering RGB LED APA106.

I try to search for any program to control this Led but most of them is for RPI and it`s not work for My OPI.

Is this connection for DIN should by for any SPI1?:

Do You have idea how to for example set change color of led ?

Regards

December 25, 2019

After reboot is fine.

However I forgot mentioned I`m update script

#!/bin/bash

echo 37 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio37/direction
echo 38 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio38/direction
echo 39 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio39/direction
echo 101 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio101/direction
echo 36 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio36/direction

while true; do

#led1	
	echo 1 > /sys/class/gpio/gpio37/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio37/value
	sleep 0.01
	
#Led2
	echo 1 > /sys/class/gpio/gpio38/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio38/value
	sleep 0.01
	
# led3
	echo 1 > /sys/class/gpio/gpio39/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio39/value
	sleep 0.01
	
#led4
	echo 1 > /sys/class/gpio/gpio101/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio101/value
	sleep 0.01
#led5
	echo 1 > /sys/class/gpio/gpio36/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio36/value
	sleep 0.01
#led4
	echo 1 > /sys/class/gpio/gpio101/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio101/value
	sleep 0.01
# led3
	echo 1 > /sys/class/gpio/gpio39/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio39/value
	sleep 0.01
	
#Led2
	echo 1 > /sys/class/gpio/gpio38/value
	sleep 0.25
	echo 0 > /sys/class/gpio/gpio38/value
	sleep 0.01
	
	
	
done

Those command works

echo 0 > /sys/class/gpio/gpio37/value
