使用sprkfun的micro:bit底座測試neopixel WS2812b燈控的功能

sprkfun的micro:bit底座的資料：micro:bit Breakout Board Hookup Guide

micro:bit版本：V2

MakeCode測試：

擴展套件：Adafruit Neopixel Driver

積木程式：

修改上圖 Pin腳位，測試結果Pin 0, 1, 2, 5, 8, 9, 11, 12, 13, 14, 15, 16可以使用neopixel。

改採Python Editor：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

from microbit import * import neopixel from random import randint # Setup the Neopixel strip on pin0 with a length of 8 pixels np = neopixel.NeoPixel(pin0, 16) np.clear() while True: #Iterate over each LED in the strip for pixel_id in range(0, len(np)): red = randint(0, 255) green = randint(0, 255) blue = randint(0, 255) # Assign the current LED a random red, green and blue value between 0 and 60 np[pixel_id] = (red, green, blue) # Display the current pixel data on the Neopixel strip np.show() sleep(300)

測試結果Pin 0~16都可以使用neopixel，但Pin 3, 4,6, 7, 10會使5x5 矩陣LED，造成不正常顯示，其主要原因是這幾支腳位做為LED Col使用。
