• OpenMV VSCode 扩展发布了,在插件市场直接搜索OpenMV就可以安装
  • 如果有产品硬件故障问题,比如无法开机,论坛很难解决。可以直接找售后维修
  • 发帖子之前,请确认看过所有的视频教程,https://singtown.com/learn/ 和所有的上手教程http://book.openmv.cc/
  • 每一个新的提问,单独发一个新帖子
  • 帖子需要目的,你要做什么?
  • 如果涉及代码,需要报错提示全部代码文本,请注意不要贴代码图片
  • 必看:玩转星瞳论坛了解一下图片上传,代码格式等问题。
  • 运行代码之后红灯常亮然后卡住



    • 运行这个代码之后openMV一开始可以运行之后就卡住了

      # Hello World Example
      #
      # Welcome to the OpenMV IDE! Click on the green run arrow button below to run the script!
      
      import sensor
      import time
      from machine import UART, LED
      
      sensor.reset()  # Reset and initialize the sensor.
      sensor.set_pixformat(sensor.RGB565)  # Set pixel format to RGB565 (or GRAYSCALE)
      sensor.set_framesize(sensor.QVGA)  # Set frame size to QVGA (320x240)
      sensor.skip_frames(time=2000)  # Wait for settings take effect.
      clock = time.clock()  # Create a clock object to track the FPS.
      
      black = (32, 100, -128, 127, -128, 127)
      uart = UART(1, 9600)
      
      LED("LED_RED").on()
      
      while uart.any()==0:
          continue
      
      LED("LED_BLUE").on()
      LED("LED_GREEN").on()
      
      while True:
          img = sensor.snapshot()  # Take a picture and return the image.
          blobs = img.find_blobs([black], invert=True, roi = [0,100,320,48])
      
          if len(blobs) == 1:
              img.draw_rectangle([0,100,320,48])
              img.draw_rectangle(blobs[0][0:4], color = (0, 255, 0))
              uart.write('#'+str(blobs[0].cx())+'$')
              print('#'+str(blobs[0].cx())+'$')
          elif len(blobs) == 0:
              uart.write('S')
              print('S')
              LED("LED_GREEN").off()
              while True:
                  continue
      

      然后就一直显示红灯运行事例中的代码酒不会出现这种情况
