Simulink Bus Serializer

This MATLAB package allows a Simulink bus to be converted into binary data and vice versa. This makes it possible, for example, to transfer a bus via UDP. Three subsystem reference models are generated on the basis of a given MATLAB struct. These reference models define the bus and perform the serialization.

1. Default Bus: Has one output port that contains the bus definition. All values can be assigned afterwards using a Bus Assignment block. Use this subsystem to create the bus for later serialization.
2. Pack Bus: Serialize the bus into a set of bytes using the machine byte-order.
3. Unpack Bus: Deserialize binary data to reconstruct the bus. The subsystem outputs a boolean success signal, that is TRUE if the binary data has been unpacked successfully (e.g. length matches).

The subsystem reference models can then be used in a Simulink model.

Getting Started

The repository is structured as a Simulink project. Add the Simulink project (BusSerializer.prj) as a reference project to an existing Simulink project so that the MATLAB package appears in the project path. Alternatively, add the package folder to the MATLAB path.

How To Use

Create a MATLAB structure and run the BusSerializer.StructToSubsystems() function.

% example structure
s.value1       = 0;
s.value2       = uint8(0);
s.nested.value = zeros(2,4,'single');

% build subsystem reference models
BusSerializer.StructToSubsystems(s, 'exampleBus');

For more information, run help BusSerializer.StructToSubsystems. An example is given in the example directory.
