Coe Composer Studio RTDX

Ayesha Siddique

Hi! I'm working on C6000 in Code Composer Studio. I have my voice data in some array in MATLAB. I want to link the MATLAB and Code Composer Studio such that RTDX help me in obtaining the voice data from MATLAB into Code Composer Studio in real time. How can I link them and use RTDX? 

Please reply me as soon as possible.

    Hello,

    Unfortunately RTDX is no longer supported and there is no similar equivalent. You will need to find an alternate way of transferring your data in real-time. Sorry

    Does the Code Composer  Studio v 3.3 also not support RTDX? rtdx.h file is included in the include folder of bios.

    CCSv3.3 does support RTDX. But CCSv3.3 itself is no longer supported.

    Please suggest me some alternate way because I've developed my whole application based on Code Composer Studio v3.3 and bios 5.31.02. I've to send some large data in real time to my code composer project. I don't want to write into the memory of code composer studio using MATLAB because it will slow down or it will effect the speed. 

    Waiting for your response.

    Unfortunately there is no good alternative out-of-the-box solution for what you are looking for. The remaining methods of raw data transfer in CCSv3 are intrusive and not real-time. You can still use RTDX with v3 if you wish but I was recommending against it because they RTDX technology has been discontinued and we can no longer help you with it.

    Ok! I'm using MATLAB v6.5 with Code Composer Studio 3.3 now. Using MATLAB I'm able to use ichan and ochan and enable and disable them in Code Composer Studio but while my code is in running condition, CCS displays a message that

    "Code Composer could not locate rtdx_usr7.c Would you like to browse for it?" 

    This rtdx_ussr.c file was never a part of my project and I added only rtdx.h file in my project for using the functions like RTDX_read etc.

    Sounds like the application is halted inside code from the RTDX library. Since we didn't ship the actual code for the RTDX library (just the library itself and generated headers), the debugger cannot find the source file. It is like stopping inside code from any library where you don't have the source for.

    If its the source file used for library project and code composer studio can't find it, inspite of it that .lib file is included in my project then how can the code composer's manufacturer provide the functuonality of the rtdx? Is there any way to get rid of this problem?

    It is the library that provides the actual functionality. The source is used to compile the library. Once the library is built, the source is not needed except in cases where you wish to do source-level debug.

    Providing libraries and header files is a common way to provide functionality while protecting IP (Intellectual Property).

    Ok! I understand. What should I do now with this error? :-(

    You can safely ignore it.

    My CCS C program remains in the running condition and when I pause, it displays this message. If i click on the option "No" then it go to an address and its is actually stucked there due to this rtdx_usr7.c file. I'm not able to recieve the inchan data from MATLAB to CCS. The garbage values appear in my recieving buffer of CCS and if I remove the command "RTDX_read" then this dialogue box doesnot appear but obviously, I've to read the data from ichan so I've to use this command as well. I'm taking guidlines for MATLAB from rtdxtutorial that comes with MATLAB and I've followed that steps for MATLAB. In CCS, I've chabged the bios configuration for RTDX for example, I enable RTDX from .tcf file and mask interrupts using 0x0000008. Using MATLAB code, CCS enable the RTDX from tools>rtdx>configuration settings> after which a dialogue box with enable rtdx option appears.

    Sorry but we cannot help you with the RTDX related questions. As mentioned before, RTDX simply is not supported anymore and the people most familiar with it here have moved on. If you are following a tutorial from Mathworks, you may want to try their support since they may still have people who are knowledgeable with the details of that tutorial.

    Good luck
