wloe2gf · 发表于 2024-10-10 08:09:28

运用microbit驱动16x16 WS2812屏，表示彩色小图案，支持动画和移动功能。

完整项目在github上，有专门的软件产生图像数据和程序，只需要点几下鼠标就能够产生绚丽的效果。

运行效果

注：需要运用功率足够的外边电源供电，不可经过microbit的3V直接供电。

参考程序：

from microbit import *

from neopixel import NeoPixel

class neo16x16_img:

def __init__(self,pin):

self.np=NeoPixel(pin,256)

def clear(self):

self.np.clear()

def show(self,dat,pos=0):

for x in range(16):

for y in range(8):

if ((x+pos)*8)>=len(dat):

self.np[x*16+y*2]=(0,0,0)

self.np[x*16+y*2+1]=(0,0,0)

else:

t=dat[(x+pos)*8+y]

r=t%16

g=(t>>4)%16

b=(t>>8)%16

if pos%2:

self.np[x*16+y*2]=(r,g,b)

else:

self.np[x*16+15-y*2]=(r,g,b)

r=(t>>12)%16

g=(t>>16)%16

b=(t>>20)%16

if pos%2:

self.np[x*16+y*2+1]=(r,g,b)

else:

self.np[x*16+14-y*2]=(r,g,b)

self.np.show()

def _delay(t):

while t>0:

t=t-1
