Call user defined C function
The C Function Call block allows to include your custom C written functions (that could contain assembly language) into the schematic. It Interfaces your functions with the MathWorks Simulink diagram. The .c file containing the code of the function should be placed in the same directory as the .mdl file. If the c file is in another directory, it must be manually added in the "Configuration Parameters > Code Generation > Custom Code > include list of additional: Source files ; Include directories ; Libraries..."
Contents
Dialog Box Parameters
Function Name
Enter your C function name between single quotes 'zzz'. Do not provide the prototype.
Global input size
Specify if the variables of the inputs are scalar (1) or vector ( >1 : array with one dimension). All different input data have the same size. they must all be either scalars nor vectors of equal dimension.
Input 1 2 3
Set the input type for the first three input. Set unused input as -- (all to -- if no input)
Output Size
Size of the output variable. It can be either a scalar (1) ; neither a vector ( >1 : array with one dimension)
Output type
data type of the output data.
Sample time
-1 means inherited
Function declaration
This is the declaration of your function in the generated Matlab/Simulink C files. Your C function declaration must be compatible with this prorotype.
Function call
This is the call of your function in the Matlab/Simulink C files. Your function must comply with this call.
- %y represent blocks output
- %u represent blocks input
