C2000 Simulink using TI DCL library functions

Hello, how to use Digital Control Library in Simulink for C2000 F28388D microcontroller? In particular, I would like to use the PID controller and the Refgen functions. The functions require pointer variables and structs as arguments. I tried so far to integrate the functions with the coder.opaque/coder.ceval command and with the C-function caller block. But there were always errors that the variable rgen does not exist.

It should be possible to call a function in the DCL library using either approach you mentioned. You will need to provide the ML Function code or C Caller block settings are are using.

To use the Refgen block, you can define the struct "rgen" in MATLAB workspace and use the "From Workspace" block to pass the struct to the Refgen block. To define the struct "rgen", you can use the following code:

rgen = struct('Type', 'Sinusoidal', 'Amplitude', 1, 'Frequency', 0.1);

Then, you can use the "From Workspace" block to pass the struct to the Refgen block.

Similarly, you can use the "From Workspace" block to pass pointer variables to the PID controller block.
