MicroPythonDeviceInterface

Class implementing an interface to talk to a connected MicroPython device.

Signals

dataReceived(data)
emitted to send data received via the connection for further processing
executeAsyncFinished()
emitted to indicate the end of an asynchronously executed list of commands (e.g. a script)
osdInfo(str)
emitted when some OSD data was received from the device

Derived from

QObject

Methods

MicroPythonDeviceInterface Constructor
connectToDevice Public method to connect to the device.
disconnectFromDevice Public slot to disconnect from the device.
execute Public method to send commands to the connected device and return the result.
executeAsync Public method to execute a series of commands over a period of time without returning any result (asynchronous execution).
handlePreferencesChanged Public slot to handle a change of the preferences.
isConnected Public method to get the connection status.
probeDevice Public method to check the device is responding.
write Public method to write data to the connected device.

Static Methods

None

MicroPythonDeviceInterface (Constructor)

MicroPythonDeviceInterface(parent=None)

Constructor

parent (QObject)
reference to the parent object

MicroPythonDeviceInterface.connectToDevice

connectToDevice(connection)

Public method to connect to the device.

connection (str)
name of the connection to be used
Return:
flag indicating success and an error message
Return Type:
tuple of (bool, str)
Raises NotImplementedError:
raised to indicate that this method needs to be implemented in a derived class

MicroPythonDeviceInterface.disconnectFromDevice

disconnectFromDevice()

Public slot to disconnect from the device.

Raises NotImplementedError:
raised to indicate that this method needs to be implemented in a derived class

MicroPythonDeviceInterface.execute

execute(commands, *, mode="raw", timeout=0)

Public method to send commands to the connected device and return the result.

If no connection is available, empty results will be returned.

commands (str or list of str)
list of commands to be executed
mode= (str)
submit mode to be used (one of 'raw' or 'paste') (defaults to 'raw')
timeout= (int (optional))
per command timeout in milliseconds (0 for configured default) (defaults to 0)
Return:
tuple containing stdout and stderr output of the device
Return Type:
tuple of (bytes, bytes)
Raises NotImplementedError:
raised to indicate that this method needs to be implemented in a derived class
Raises ValueError:
raised in case of an unsupported submit mode

MicroPythonDeviceInterface.executeAsync

executeAsync(commandsList, submitMode)

Public method to execute a series of commands over a period of time without returning any result (asynchronous execution).

commandsList (list of str)
list of commands to be execute on the device
submitMode (str)
mode to be used to submit the commands (one of 'raw' or 'paste')
Raises NotImplementedError:
raised to indicate that this method needs to be implemented in a derived class
Raises ValueError:
raised to indicate an unknown submit mode

MicroPythonDeviceInterface.handlePreferencesChanged

handlePreferencesChanged()

Public slot to handle a change of the preferences.

MicroPythonDeviceInterface.isConnected

isConnected()

Public method to get the connection status.

Return:
flag indicating the connection status
Return Type:
bool
Raises NotImplementedError:
raised to indicate that this method needs to be implemented in a derived class

MicroPythonDeviceInterface.probeDevice

probeDevice()

Public method to check the device is responding.

If the device has not been flashed with a MicroPython firmware, the probe will fail.

Return:
flag indicating a communicating MicroPython device
Return Type:
bool
Raises NotImplementedError:
raised to indicate that this method needs to be implemented in a derived class

MicroPythonDeviceInterface.write

write(data)

Public method to write data to the connected device.

data (bytes or bytearray)
data to be written
Raises NotImplementedError:
raised to indicate that this method needs to be implemented in a derived class
