StreamDock Base Class

The control classes of all specific device models need to inherit the StreamDock base class, which provides the following methods:

Open the device

def open(self):
   self.transport.open(bytes(self.path,'utf-8'))

Turn off the device

def close(self):
    self.disconnected()
    ## self.transport.close()

Disconnect Clear all displays

def disconnected(self):
    self.transport.disconnected()

Clear a button's icon

def cleaerIcon(self,index):
    self.transport.keyClear(index)

Clear all button icons

def clearAllIcon(self):
    self.transport.keyAllClear()

Wake up the screen

def wakeScreen(self):
    self.transport.wakeScreen()

Refresh device display

def refresh(self):
    self.transport.refresh()

Get device path

def getPath(self):
    return self.path

Get information from device feedback

def read(self):
    """
    :argtypes:Byte array for storing information.
    The recommended length of the byte array is 512
    """
    arr=self.transport.read()
    return arr

Keep checking whether the device has any information feedback. It is recommended to start another thread to use

def whileread(self):
    while 1:
        arr=self.read()
        if len(arr)>=10:
            if arr[9]==0xFF:
                print("Write Success")
            else:
                print("Button{}".format(arr[9]))
                if arr[10]==0x01:
                    print("Pressed")
                else:
                    print("Up")
        else:
            print(arr)
        del arr

Get the device serial number

@abstractmethod
def get_serial_number(self):
    pass

Set button icon

@abstractmethod
def set_key_image(self, key, image):
    pass

Setting Brightness

@abstractmethod
def set_brightness(self, percent):
    pass

Setting the touch screen image

@abstractmethod
def set_touchscreen_image(self, image):
    pass

Set the button icon through imagedata

@abstractmethod
def set_key_imagedata(self, key, image,width=126,height=126):
    pass
