You can write a small amount of python to test that the image you have created works correctly.
The following is a tiny python script that takes an image from the camera and displays it on the built-in screen.
Connect to the device via the serial link or over ssh.
Create a test.py file with the
#!/usr/bin/env python from maix import display, camera while True: display.show(camera.capture())
Make the script executable via
chmod +x test.py
Run the script
The rear display should now show images of what the camera points at.
The built-in firmware includes a demonstration application that can do image recognition for a set of objects. You can launch this by running the main.py script.
