Running neopixel on Jetson Nano #91

Closed i1212-blip closed 4 years ago

i1212-blip commented 4 years ago

Is there a way to run the library neopixel on jetson nano instead of running neopixel_spi? I'm facing a problem with jetson when using neopixel_spi. I'm trying to turn on 300 num pixels using an addressable led. When running the script; 168 led turns on instead of 300. I tried to increase the number of bytes(4096) but nothing changed. When running the script on Raspberry pi using neopixel library; it works perfectly.

Below is the following script :

""" import time import board import neopixel_spi as neopixel

NUM_PIXELS = 300 PIXEL_ORDER = neopixeL.RGB COLORS = (0xFF0000, 0x00FF00, 0x0000FF) DELAY = 0.1

spi = board.SPI()

pixels = neopixel.NeoPixel_SPI(spi, NUM_PIXELS, pixel_order=PIXEL_ORDER, auto_write=False)

while True: for color in COLORS: for i in range(NUM_PIXELS): pixels[i] = color pixels.show() time.sleep(DELAY) pixels.fill(0)

"""
