测试openmv 与 arduino 第一次 通信成功 里的代码有几处出错,不明白为什么
-
import sensor, image, time
import json
from pyb import UART
sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # use RGB565.
sensor.set_framesize(sensor.QQVGA) # use QQVGA for speed.
sensor.skip_frames(10) # Let new settings take affect.
sensor.set_auto_whitebal(False) # turn this off.
clock = time.clock() # Tracks FPS.
uart = UART(3, 9600)
while(True):
clock.tick() # Track elapsed milliseconds between snapshots().
img = sensor.snapshot() # Take a picture and return the image.
img.lens_corr(1.5)
for code in img.find_qrcodes():
message = code.payload()
uart.write(message)
print(code)
else:
print(“not found!”)

起码你要说一下什么目的,什么错误吧……

我想通过openmv把如果检测到前面是 红灯 就给arduino串口发个信息,在电脑前研究了很长时间,都不行

可以你的代码,和你的目标,一点关系都没有......
