Integrate C Code Using C Caller Blocks

Call simple external C code into Simulink^® by importing C functions

Use the C Caller block to integrate your C code into Simulink models. The C Caller block resolves source C code and extracts the functions to utilize in your Simulink models. To get started by configuring custom code sources in your Simulink model, see Specify and Configure Custom C/C++ Code.

The C Caller block does not support dynamic states and variables. To use dynamic states and variables in your custom block, see Author Blocks Using C MEX S-Functions.

Generating code using the C Caller block eliminates the need for writing Target Language Compiler (TLC) files.
