串口通信是openmv·里的程序·不会自启动
-
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
