Hello Lubin,

I am trying to implement the software emulation EEPROM as described in Microchip's App Note AN1095 http://www.microchip.com/stellent/idcpl ... e=en530593. This is what I am doing:



I downloaded the code and renamed the C, S and H files to DEE.c, DEE.s and DEE.h respectively. Then I added those to the Simulink model via Simulation -> Configuration Parameters -> Custom Code. I place the S and C files in Source Files and the H file in Header File. I am still not doing anything with the model except flashing an LED and trying to compile. When I compile I get this error:

Now, for a minute I contemplated the fact that the Header File could have a syntax error, I checked it and it does not. Also, I then compiled the downloaded MPLab project that comes with the App Note without any complaints.



I have attached the Mdl and the C, S and H files. Any help would be greatly appreciated.

It turns out I found the problem. Actually there were 2 problems. I hope Lubin has a clear explanation for the first one:



1.- H File: The H file SHOULD NOT go in the Simulation->Config Parameters dialog. You just need to include it in your C file. No clue why.



2.- DEE.C and DEE.S both created a DEE.o object which when linked, broke everything :-S. Yes I know, simple one, sorry :-).



I am posting this to help anybody else in the same boat.

Hi Mariano,



I converged to the same solution. You were quicker!



Anyway, the model compile without any 'C function Call' block, but when I am trying to access to one function, It is not ok !

It has maybe to do with the .h file that we do not declare...

SPIMasterTest.o(.text+0xe2):C:\prog\Matlab2\RTWdsPIC\Developpements\Forum\Mariano_EEPROM\SPIMasterTest_dspic\sources\SPIMasterTest.c: undefined reference to `GetPagePackSkipped' 

I noticed that when we include the .h file, error appears on a specific part of the .h file where we have syntax that I am not used to ... ( : start a 2 lines ?)

__extension__ typedef struct tagNVMCONBITS {
  union {
    struct {
      unsigned NVMOP:4;
      unsigned :2;
      unsigned ERASE:1;
      unsigned :6;
      unsigned WRERR:1;
      unsigned WREN:1;
      unsigned WR:1;
    };
    struct {
      unsigned NVMOP0:1;
      unsigned NVMOP1:1;
      unsigned NVMOP2:1;
      unsigned NVMOP3:1;
    };
  };
} NVMCONBITS;

I guess I did not choose the right function name to call.



This model compile.
