Hello Lubin,

This is the first time that I try to build a model with a PIC32. Till now without any succes and a lot of errors.

When I try to build your model hypersampling I get the next error:

My idea is that there must be somewhere a fundamental mistake, but I do not know where to look.

Hello Lubin,

I solved my problem by re-installing the C30 and C32 compilers again.

No problems anymore with your model Hypersampling.

But with the attached model (with any kind of filter), I get the following message (without a filter no problems):



C:\PROGRA~1\MATLAB\R2008b\toolbox\rtw\dspblks\c\dsppinv/pinv_d_rt.c: In function `MWDSP_PINV_D':

with preprocessed source if appropriate.

Hi Casparus,



I open the model (with matlab 2009a) and compile it without problems.

I attached the .hex file generated.



I was wondering if the time-step is not to fast. at 30Khz, it would be better to use fixed point filter. You may considere using the busy flag port (see master block options)



It seems that the error you get comes from the C compiler. It's is strange as I am using the same C compiler (I use the last version of C32) :

>> !pic30-gcc -v
gcc version 4.0.3 (dsPIC30, Microchip v3_11) Build date: Jul 16 2008 
Microchip Language Tool Shell Version v3_11 (Build date: Jul 16 2008). 

Lubin

Hello Lubin,

I followed your advises and tried to eliminate every possible fact that could cause an error. I even re-installed the C32 compiler (and a fixed point fillter).

But always the same error appears:

I use the latest evaluation C32 V 1.05 and Matlab 2008b.

Without a filter I can build the model.



Casparus

Hi Casparus,



I tested the model with matlab 2008b and I get the same error.

It seems that matlab 2008b generate code that make the compiler to bug. I do not have solution for that.



As the problem is due to the filter block fdatool, you may easily find a workaround : from the fdatool, generate a simulink subsystem with the filter implemented with simple elements , i.e. addition, delay and gain. This should work.
