Hello I’m new to this Forum.
I was following the LED WS2812B Tutorial on this page: How To Use Addressable RGB WS2812B LED Strips With a Raspberry Pi Single Board Computer - YouTube
Now i have the Problem that if I’m running a script with some commands for the LED after around 40 seconds the GPIO 18 Pin stops sending any signals and the LEDs just freeze in place.
I am relativly sure its not my code since I tryed different versions of it, the last one very simple just swiches between red and blue for all LEDs in a infinite loop and that freezes too.
I also dont think its the LEDs i bought since i measured the voltage on the GPIO pin itself and it just goes down to 0 after around 40 seconds.
And now im out of ideas.
Here my code if it helps:
#!/usr/bin/env python3 import time from rpi_ws281x import * import argparse # LED strip configuration: LED_COUNT = 60 # Number of LED pixels. LED_PIN = 18 # GPIO pin connected to the pixels (18 uses PWM!). #LED_PIN = 10 # GPIO pin connected to the pixels (10 uses SPI /dev/spidev0.0). LED_FREQ_HZ = 800000 # LED signal frequency in hertz (usually 800khz) LED_DMA = 10 # DMA channel to use for generating signal (try 10) LED_BRIGHTNESS = 10 # Set to 0 for darkest and 255 for brightest LED_INVERT = False # True to invert the signal (when using NPN transistor level shift) LED_CHANNEL = 0 # set to '1' for GPIOs 13, 19, 41, 45 or 53 # Main program logic follows: if __name__ == '__main__': # Process arguments parser = argparse.ArgumentParser() parser.add_argument('-c', '--clear', action='store_true', help='clear the display on exit') args = parser.parse_args() # Create NeoPixel object with appropriate configuration. strip = Adafruit_NeoPixel(LED_COUNT, LED_PIN, LED_FREQ_HZ, LED_DMA, LED_INVERT, LED_BRIGHTNESS, LED_CHANNEL) # Intialize the library (must be called once before other functions). strip.begin() print ('Press Ctrl-C to quit.') if not args.clear: print('Use "-c" argument to clear LEDs on exit') try: while True: print("Cycle Again") for i in range(LED_COUNT-1): strip.setPixelColor(i, Color(255, 0, 0)) strip.show() time.sleep(0.5) for i in range(LED_COUNT-1): strip.setPixelColor(i, Color(0, 255, 0)) strip.show() time.sleep(0.5) except KeyboardInterrupt: print("exit") strip.setBrightness(0) strip.show()
