Problem of configuring a dspic with Simulink Blockset

Postby dsPIC_ENP » Tue Apr 20, 2010 10:50 pm

Hi,
I have programmed a dsPIC named 33FJ32MC202 with the palteform of simulink and I can get 04 PWM from 06.

PWM 1H,L and PWM 2H,L are activated. although I have activated all of my PWM in the programme.

The code generated by the simulink blockset is attached.

Thank you for helping me.

Hi,

could you also post the simulink model file ? Here are onlymplab projects file

Hi,
You find the SIMULINK project attahched. I have written a code in c. All PWM pins work. But with the interface I have only 04 PWM that are working.

Thank you.

Hi,

You are using Microchip blockset.
Please give a try using this one:

Hi,

I am using the simulink blockset which you advise me. I can get A c code but I am not able to get the .hex code.

So the programme is attached.

The error that I have is:

You're not very lucky, you find a bug in my toolbox also ;-)

Thus, here is the generated code for the file with the error :

I could not see obvious error here. If you got any ideas it would be helpfull !

hello,
I have bump into a similar problem when I worked with dspic30.

i have build a simple model that power a brushless motor using i2c. here is the model:
ex6_i2c.mdl
(34.24 KiB) Downloaded 199 times


The HEX file couldn't been created by the matlab, but it succeed to generate the code.
when i opened the mplab project and try to build it from there i have noticed that the problem is connected with the following line in the main file:

_FOSC(CSW_FSCM_OFF & CSW_FSCM_OFF)
_FWDT(WDT_OFF)
_FBORPOR(PBOR_OFF & PWRT_OFF & MCLR_EN)
_FGS(CODE_PROT_OFF)
_FICD( ICS_PGD1 )


so i deleted those lines and set the "bit configuration" manually to the following values:
2011-12-14_143339.jpg


after that, it have build successful.
Since then, i did those step to any model that i made for the dspic30.


I hope that it can give you a clue about the nature of the problem

Alpert.

Alpert,

This look like a problem with few compilers version as the FICD register were renamed as ICD.
Some blockset version used FICD or ICD as register to comply with the latest compiler.

please download the latest C30 (v3.31) compiler version and the latest blockset (v3.7c)
Everything should works fine now.
