Strip Led is not working
kabcasa opened this issue · comments
using GROVE BASE HAT RPI with Grove - RGB Led ring (16-WS2813 Mini)
On Rpi 3B Buster version
The Led are on PWM slot .
i can't get the leds switch on
and no error message is given
code :
from grove.i2c import Bus
from rpi_ws281x import PixelStrip
from time import time, sleep
from grove.gpio import GPIO
from RPi import GPIO as io
def light_led(led, pix, r, g, b):
for pixel in range(pix):
led.setPixelColorRGB(pixel, r, g, b)
print("led mode {} {} {}".format(str(r),str(g),str(b)))
led.show()
led20 = PixelStrip(16, 12) # Grove RGB led connected to grove PWM
led20.begin()
light_led(led20, 16, 55, 0,0)
sleep(5)
light_led(led20, 16, 0, 55, 0)
sleep(5)
led20._cleanup()
in grove.py there's an example grove_ws2813_rgb_led_strip.py, does this one work?
i test it also it's the same the led doesn't switch on
Can this help you
Same, Im trying to work out with the LED Strip. 1. Which Grove Port do you plug into? Why does it mention PIN when it's using a Grove Shield.
