text: # High FPS Example
  #
  # This example shows off how to make the frame rate of the global shutter camera extremely
  # high. To do so you need to set the resolution to a low value such that pixel binning is
  # activated on the camera and then reduce the maximum exposure time.
  #
  # When the resolution is 320x240 or less the camera reads out pixels 2x faster. When the
  # resolution is 160x120 or less the camera reads out pixels 4x faster. This happens due
  # to pixel binning which is automatically activated for you to increase the readout speed.
  #
  # While the readout speed may increase the camera must still expose the image for the request
  # time so you will not get the maximum readout speed unless you reduce the exposure time too.
  # This results in a dark image however so YOU NEED A LOT of lighting for high FPS.
  
  import sensor, image, time
  
  sensor.reset()                      # Reset and initialize the sensor.
  sensor.set_pixformat(sensor.GRAYSCALE) # Set pixel format to GRAYSCALE
  sensor.set_framesize(sensor.QQVGA)  # Set frame size to QQVGA (160x120) - make smaller to go faster
  sensor.skip_frames(time = 2000)     # Wait for settings take effect.
  clock = time.clock()                # Create a clock object to track the FPS.
  
  sensor.set_auto_exposure(True, exposure_us=5000) # make smaller to go faster
  
  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.
