Linux Systems (Ubuntu/Debian)

You need to install pillow, pyudev, threading, ctypes, time, abc

pip install pillow

pip install pyudev

pip install threading

pip install ctypes

pip install time

pip install abc

When using it, you need to first define a DeviceManager class object (device manager class), and then call its enumerate() function to traverse the devices and obtain a list of device objects.

manner = DeviceManager();
streamdocks = manner.enumerate();

After obtaining the list of device objects, you need to call the open() method to open the device before calling other methods to operate on the device.

 for device in streamdocks:
    device.open()
    device.refresh()
    t1 = threading.Thread(target=device.whileread)
    t1.start()
    # 0-100
    device.set_brightness(100)
    device.set_touchscreen_image("1.jpg")
    time.sleep(1)
    device.set_key_image(3, "2.jpg")
    time.sleep(1)
    device.cleaerIcon(3)
    time.sleep(1)
    device.clearAllIcon()
    device.refresh()
    time.sleep(1)
    device.close()
    time.sleep(1)
