integrate C code in block simulink for C2000

Hi to all,

I wrote some functions in C language to read the registers of C2000 and to monitor their status.

I would like to integrate this C code in a block simulink.

How do I integrate this C code in simulink?

There are examples of this integration ?

I am using MCU F28035 Piccolo and Matlab 2014a

Best Regars,

Hi Dario,

take a look at the following point in the doc:

http://www.mathworks.com/help/releases/R2014b/simulink/custom-block-basics.html

You will need to write an S-function for this. There are a larger number of examples, often the S-Function Builder is a good starting point since it guides you through the different things you need to specify (number of in- and outputs, sample time etc.).

Hi titus ,

i want to read / write some registers of C2000 in simulink. For example in a simulink block , I would like to do this :

       GpioDataRegs.GPASET.all    =0xAAAAAAAA;
       GpioDataRegs.GPACLEAR.all  =0x55555555;

       GpioDataRegs.GPBSET.all    =0x0000000A;           
       GpioDataRegs.GPBCLEAR.all  =0x00000005;

how could I do?

Best Regards,

Dario

Hi Dario,

this will be difficult with S-Function builder. In this case you will need to write a .tlc file. Note: this is documented how to do but not really simple, admittedly ... MathWorks Consulting does help with those kind of problems/requests.

Hello Dario, I'm also interested in programming this controller in Simulink. Did you finally get to solve it with S-Function Builder modules? Thanks Patxi
