Add Adapter programatically to system composer model

Hello community,

i am trying to add an interface adapter to a system composer architecture programatically. I only can add components using addcomponent().

How is it possible to add a adaoter or do i need to convert the component into an adapter in some way? I am lost at the moment.

Thanks in advance!

Best Regards Andreas

Hi @Andreas,

There is no API for creating adapters but you can create a component that performs the same actions using the SourceElement and DestinationElement Name-Value Arguments of the connect command. Here is an example:

% Load the architecture model and get the architecture where you want to
% add the components (in this case, the top-level).
a1Model = systemcomposer.loadModel('a1');
a1Architecture = a1Model.Architecture;

% Get the handles of the components and ports to be connected
txLeft     = getComponent(a1Architecture, 'TX_Left');
txLeftOut  = getPort(txLeft, 'TX_Out');
txRight    = getComponent(a1Architecture, 'TX_Right');
txRightOut = getPort(txRight, 'TX_Out');
rx         = getComponent(a1Architecture, 'RX');
rxIn       = getPort(rx, 'RX_In');

% Create a component that will act as the adapter and add its architecture
% ports.
adapter = addComponent(a1Architecture, 'MyAdapter');
addPort(adapter.Architecture, 'TX_Out_Left', 'in');
addPort(adapter.Architecture, 'TX_Out_Right', 'in');
addPort(adapter.Architecture, 'RX_In', 'out');

% Get the corresponding component ports of the new adapter architecture ports.
adapterTXLeft  = getPort(adapter, 'TX_Out_Left');
adapterTXRight = getPort(adapter, 'TX_Out_Right');
adapterRX      = getPort(adapter, 'RX_In');

% Connect the component ports together
connect(txLeftOut, adapterTXLeft)
connect(txRightOut, adapterTXRight)
connect(adapterRX, rxIn)

% Clean up the diagram
Simulink.BlockDiagram.arrangeSystem('a1')

% Create the internal mappings inside of the architecture of the adapter.
% Could also have saved these from the return of the addPort command.
adapterTXLeftA  = adapterTXLeft.ArchitecturePort;
adapterTXRightA = adapterTXRight.ArchitecturePort;
adapterRXA      = adapterRX.ArchitecturePort;

connect(adapterTXLeftA, adapterRXA, DestinationElement='TX_Left')
connect(adapterTXRightA, adapterRXA, DestinationElement='TX_Right')

% Clean up the diagram
Simulink.BlockDiagram.arrangeSystem('a1/MyAdapter')
