    • 光源扩展板和拍照代码共同运行会出现卡顿,有没有什么改进方法?代码如下

      import sensor, image, time
      import time
      from pyb import Pin, Timer

      light = Timer(2, freq=50000).channel(1, Timer.PWM, pin=Pin("P6"))
      light.pulse_width_percent(10) # 控制亮度 0~100
      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.

      while(True):
      time.sleep_ms(200)
      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.
