8. 二维码识别

8.1. 代码

例程:

from mpython import *
import smartcamera_new as smartcamera
import time

smart_camera = smartcamera.SmartCamera(tx=Pin.P16, rx=Pin.P15)
smart_camera.qrcode_init(1)
smart_camera.qrcode.add_qrcode(2)
while True:
    smart_camera.qrcode.recognize()
    if smart_camera.qrcode.id != None:
        print(smart_camera.qrcode.id)
    time.sleep_ms(20)
