TMS320F28335: Connecting Code Composer program with my python program (Controlling ePWM(Freq, dutycycle), build and debug the simulation all through python instead of Code composer workspace

Muhammad Arsalan Athar

Part Number: TMS320F28335

Hi Team members.

I run my code using code composer studio that generates two ePWM signals for my Power Circuits. I also have my Python code which connects Oscilloscope,multimeters (for readout the results) and Power Supplies to supply the input power for my Power Circuits, all connected with my pthon program which I already have done this.

The problem is that I want to automate the system by connecting the Code Composer program with my Python program that will generate Freq, duty cycle, build, and debug the simulation all through Python instead of Code Composer workspace.

The code that i wrote for generating ePWM signals is only run through code composer studio (build, debug) and is checked or measured through an oscilloscope. But now I need to write this routine in my Python program to control ePWM signals and to run the simulation using my Python code instead of writing the code in CCS workspace.

The COM port XDS 100 class USB serial port is used for connecting my DSP (F28335)

Please suggest accordingly.

Thanks

Kind Regards

Hi Arsalan,

To clarify, you are not having issues specifically with EPWM, correct? You have the desired code for your application and you are trying to use a python script to automate the building/running of a CCS project?

Best Regards,

Allison

Hi Allison Nguyen,

Thanks for your reply.

Correct ! no issues with EPWM codes. I have tested, built and run through CCS workspace.

Yes. Also I need to give all the inputs from python scripts such as: If i want to change the freq ( like TBPRD, ...etc), I will change through my python scripts by writing codes in my current python program not from CCS workspace window. Because my other instrument scripts are controlled through my Python scripts.

Please suggest accordingly.

Kind Regards

Hello,

I believe you want to control the CCS debugger from your python script. If so, please see:

https://software-dl.ti.com/ccs/esd/documents/dss_python_dss_scripting.html

Note that DSS is for automating the debugger only. If you want to be able to build your CCS project from your script, you can execute the below CLI commands from your script:

Thanks

Hello Ki,

Thanks for your reply.

As you said DSS scripts are for debugging. It means, that I can configure Target Configuration (.ccxml), Connect the Target, Load the program from my CCS workspace, and then run it. ???

Therefore, in my Python scripts, all the commands should be written that will be used for the above tasks ( configure Target Configuration (.ccxml), Connect the Target, Load the program & Run the program) Right???

No coding for EPWM should be there in my Python script. It will automatically read from my CCS workspace (.c file) Right??? Is it possible if we write code our EPWM code in my Python scripts instead of the CCS workspace and then do all the above steps ???

Similarly, the Build can be done through CLI commands.

Please clarify the above questions.

Thanks

Regards

Typically DSS is run from the system console (like DOS command window). But you can run it from inside the CCS IDE using the Scripting Console:

However, the Scripting Console is a javascript console so you will need to use javascript there.

If you want to use Python, you will need to run from system console CLI.
