Automatically modify variable value during runtime

Yanbin Zhao92331

Dear All:

I have a requirement: I need to do an interface integration test. Let's say there's a global variable "ui16_A". It's an interface. It will be modified by other 3rd party software module and then my developed software value will use its value for calculation. At last another variable "ui16_B" will be affected.

Are there any method (for example, script in CCSvX) that can automatically modify this value, then execute my code (in laptop or target) and display the result "u16_B"?

Thank you all.

Hello,

What device and CCS version are you using?

Thanks

Hallo Lee:

We are using TMS320F2806x, TMS320F2803x.

We are using CCSv5.5.0 development environment.

Actually I can insert some dummy code to set the value for "interface", but this time I don't want to modify the source code and I want this process to be run automatically.

I know that there're some test softwares can do this. They analyze the source code, recognize the global variables, internal functions, external functions and test source code with defined testcases or stub functions. But these tests are running on PC instead of my target MCU or DSP.

This time I want to do it in CCS and I want to verify my software function together with HW!

Those devices support real-time debug. You should be able to write to that variable while the target is running without halting the processor. You can use a GEL or DSS script to automate this.

Thanks

Hello, Ki:

Do you have manuals for GEL or DSS?

GEL is well documented in the Help that comes with CCS (Help ->Help Contents->Code Composer Studio Help->Tasks->Automating Tasks with General Extension Language)

For DSS, see:
