例程:

from mpython import *
from camera import *
import time

camera = CameraV831(tx=Pin.P16, rx=Pin.P15)
camera.track_init()
camera.track_set_up([[0, 80, 15, 127, 15, 127], [0, 80, -70, -10, 0, 30]],100)
while True:
    camera.track.recognize()
    if camera.track.x != None:
        print(camera.track.x)
        print(camera.track.cx)
        print(camera.track.pixels)
    print('===')
    time.sleep_ms(20)
