  • 我们只解决官方正版的OpenMV的问题(STM32),其他的分支有很多兼容问题,我们无法解决。
  • 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。
  • 串口接收数据,程序只执行一下子,openmv直接卡死,报错

    • 传递过来的数据是‘L\n’



    • 你的代码不对,if recieve == 'L':应该在if uart.any():里面。

      import sensor, image, time
      from pyb import UART
      
      sensor.reset()                      # Reset and initialize the sensor.
      sensor.set_pixformat(sensor.GRAYSCALE) # 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.
      
      uart = UART(3, 115200)
      a=0
      
      while(True):
          clock.tick()                    # Update the FPS clock.
          img = sensor.snapshot()         # Take a picture and return the image.
          print(clock.fps())              # Note: OpenMV Cam runs about half as fast when connected
                                          # to the IDE. The FPS should increase once disconnected.
          #code = 'A'

          if uart.any():

                  print("We win.")
                  a=a+1
                  print(a)

      我用串口助手发送数据,没发现问题。
