串口通信是openmv·里的程序·不会自启动

[HlikeL]

请在这里粘贴代码import sensor, image, time,pyb   
from pyb import UART           
import json
green_threshold   = (   7,   100)   

uart = UART(3,115200,timeout_char = 1000000)      
ROI=(73,36,168,166)       
sensor.reset()
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framesize(sensor.QVGA)
sensor.set_windowing(ROI)      
sensor.skip_frames(10)
sensor.set_auto_gain(True)
sensor.set_auto_whitebal(False) 
led = pyb.LED(3)
while(True):
        clock.tick()
        img = sensor.snapshot()
        blobs = img.find_blobs([green_threshold],x_stride=2,y_stride=2,area_threshold=6)
        led.on()
        if blobs:       
                for b in blobs:
                        img.draw_cross(b[5],b[6])       
                        print(b[5],b[6])
        output_str=bytearray([0xff,0xee,int(b[5]),int(b[6])])  
        uart.write(output_str)
        print(clock.fps())
程序用IDE里测试时没有问题

代码有问题，你在IDE里试试就知道了。

NameError: name 'clock' is not defined
