The S-function builder also serves as a wrapper for the S-functions generated in your models. Use the C Caller block to call a C function to your model that has no states. To create an S-function without states, use Legacy Code Tool. If you would like to work with states and methods, use the S-function Builder or S-functions. Bring in C code image filter algorithms using C Caller blocks in a reusable Simulink library.

Simulink S-functions allow you to extend Simulink with new hand coded blocks, interface to custom external code, and create live interfaces to other programs.

Using Function Caller blocks, you can call a function from anywhere in a model or chart hierarchy. The function prototype determines the number and name of input ports that appear on the Function Caller block.

Connect signal lines to the input ports to send data to a function through the function input arguments. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 Boolean fixed point enumerated bus. The function prototype determines the number and name of output ports that appear on the Function Caller block.

Connect signal lines to the output ports to receive data from a function through the function output arguments. Specify the function interface between a Function Caller block and a Simulink function. For a call to a Simulink Function block:. Specify a comma-separated list of MATLAB expressions that combine data type, dimensions, and complexity real or imaginary for each input argument.

This specification must match the Simulink Function block data type specified with the Data type parameter of the Argument Inport block. Specify a comma-separated list of MATLAB expressions that combine data type, dimensions, and complexity real or imaginary for each output argument. This specification must match the Simulink Function block data type specified with the Data type parameter of the Argument Outport Block.

Specify the time interval between function calls to a subsystem or model containing this Trigger block. If the actual calling rate for the subsystem or model differs from the time interval this parameter specifies, Simulink displays an error. Vector where Ts is the time interval and To is the initial time offset.

How clients, in this case three computers, can send jobs to a server, a printer, and receive status from that server.

Multiple instancing provides the ability to reuse this logic as CounterA and CounterB in this application model.

The advantages of the C Caller block are:.

Call a Legacy Lookup Table Function Using C Caller block

The C Caller block allows you to bring C algorithms into Simulink. To model dynamic systems, use the S-Function Builder instead. Next steps describe the workflow to integrate C code into Simulink using the C Caller block.

From Simulink toolstrip, open the Configuration Parameters. To enable code parsing by the C Caller block, ensure that the Import custom code box is selected. The directories and file paths can be absolute and relative file paths to model directories or to the current working directory.

Select Header file and enter the name of your header file with the include tag. Under Additional build informationselect Include directoriesand enter the folders where additional build information, such as header files, are stored. Select Source files and enter the path and the name of the source file. If the model and the source files are in different directories, enter the directory that contains the source file before the file name.

If a function is declared in the header file but not implemented in the source code, an empty stub function is automatically generated to simulate and compile the model. You can specify the order of how your matrix data is stored in Simulink.

Matrix data passed to and from your C functions is converted to the default function array layout you specify. If the function array layout is not specified, the matrix data is passed through the C Caller in the same order of your Simulink data, and computational errors may occur due to row-column major disarrangement.

Ensure that you follow the same default function array layout for all Simulink data. Suppose that you have a 3-by-3 matrix. In the C Caller block, this matrix is stored in this sequence: first column, second column, and third column.Documentation Help Center.

Using Function Caller blocks, you can call a function from anywhere in a model or chart hierarchy.

I am building a Simulink model in order it generates the C-code equivalent. Actually, the C-code doing that already exists but I want to visualize it with Simulink. I know that the code Simulink will generate will not be the same than the one it is based on, but there are some functionalities I want to keep.

For example, I use a lot of Macro define in the C code, to be more readable and I really do not know how to force Simulink to define these macro's. Learn more. Asked 5 years, 2 months ago.

Call C Functions Using C Caller Block

Active 4 years, 5 months ago. Viewed times. I thank you a lot for any lead you could propose. Depending on the macros, they can actually make the code less readable. Here it would really help and more important, it is mandatory. Now my problem is that Simulink introduces a cast in my macro definition when generating the code.

I would prefer to have nothing. This is actually possible if I keep the type double but I am working with fixed-point types. What can I do to combine both constraints? This latter request is a constraints from the existing code Active Oldest Votes.
