Simulink - Code Composer Studio V3.3 Interface

Hello,

I'm working with Simulink - Code generation - CCS v3.3 - eZdsp F2812 and I want to know if it's possible to make changes in a Simulink model and those changes to take action in CCS without re-build the model.

For example if I turn ON/OFF the XF/XPLLDISn- LED bit F14, using a constant blok, and I want to change that constant from 1-ON to 0 - OFF without re-building the model.

Thanks very much to all! Ana

Which version of MATLAB are you using? (Type "ver" on the MATLAB command line and paste the output here).

It sounds like you want to use the "External mode" feature. With External mode, changing a parameter value in the model automatically changes that value in the application while it is running on the target hardware.

To see some relevant documentation, enter the following command in the MATLAB Command Window:

* web([docroot '/toolbox/rtw/ug/f1000932dfi4.html'])

* web([docroot '/toolbox/rtw/ug/bp6h8fr-1.html'])

* web([docroot '/toolbox/rtw/ref/bq_a_2b-1.html#bq_coss-1'])

To see some demos, search the documentation for: C2000 demo "External Mode"

Thank you! I'll try that.

Hi, In my past job, I used a similar setup (CCSv3.3 + F28335). I presume you have Embedded Coder. It sounds like you don't want to use a constant block for that purpose. It sounds like you need to use the From RTDX block instead, then set up an RTDX communication channel to MATLAB. http://www.mathworks.com.au/help/toolbox/ecoder/ref/c2000fromrtdx.html Due to time constraints, I never verified this feature, but it is a supported feature with some documentation available as posted above. Good luck.

please how to turn on one led with ccs v3.3 via TMS320F2812

Answer 4

[sonfack lionel leroy]

i have a new TI board eZdspTM F2812.

1- i don't know how to select well all jumper on the board. i want to turn on a led by using ccs v3.3

2- i don't know if i will choose c28xx emulator or c28xx simulator in ccs v3.3

3- please i need a good practical example for the test ; so that to verifier if my dsp board is functionning
