9. Read and Write Memory Card Experiment

Routine Code

import sensor, image, time

sensor.reset()                      # Reset and initialize camera
sensor.set_pixformat(sensor.RGB565) # Set camera output format to RGB565 (GRAYSCALE also supported)
sensor.set_framesize(sensor.QVGA)   # Set camera output size to QVGA (320x240)
sensor.skip_frames(time = 2000)     # Skip 2000 frames
clock = time.clock()                # Create a clock object for FPS calculation

print("You're on camera!")
img = sensor.snapshot()             # Capture an image

# Save image as JPG, BMP, or other formats
img.save("/sd/example.jpg") # or "example.bmp" (or others)

print("Done! Reset the camera to see the saved image.")

Experiment Preparation

• 1. Prepare a TF card and insert it into the K210.
• 2. Connect the K210 to your computer via USB.
• 3. Open CanMV IDE and run the routine code above.

Experiment Results

• 1. After running, the K210 captures the camera feed and saves it to the TF card. On the TF card you will find example.jpg—opening it shows the captured image.
