from luma.core.interface.serial import spi, noop
from luma.led_matrix.device import max7219
from luma.core.render import canvas
import time
serial = spi(port=0, device=0, gpio=noop())
device = max7219(serial)
while True:
with canvas(device) as draw:
draw.rectangle((0, 0, 7, 7), outline=”white”, fill=”black”)
time.sleep(0.5)
with canvas(device) as draw:
draw.rectangle((2, 2, 5, 5), outline=”white”, fill=”white”)
time.sleep(0.5)
