Variables values not visible in CCS 5.5

Other Parts Discussed in Thread: TMS320F28335, CCSTUDIO

Hi all,

I am using the CCS 5.5.0.00077 with TMS320F28335 Experimental kit.

1) In the "Variables window" tab I am not able to see the values of local or global variables. After I first installed CCS the "Variables window" did worked and displayed variable values with example projects. But after few weeks, its just blank. I am using one of the example project from ContolSUITE for ADC module, executing from RAM. I didn't change any setting in the IDE other than the stack size to 0x380.

I tried right click on the array and use "Add to Expression", but it doesn't display all the values of the voltage array,
it just displays the last value. I want all the values to be displayed, to later export them.

2) I did read through other post and tried enabling "Silicon Real-time mode" in the debug window but as soon as I hit Run, it shows an error no. 1142, Trouble Reading Register PC. Please find error message attached. But if I disable it my code runs smoothly with no errors. Can you explain what this mode actually does? I do want to later run the program for real-time applications.

Thank you for your help.

Hi Pankaj,

Try changing the workspace.

Hi Gautam,

I changed the workspace location, but still I can't see the variable or array in the Variable window.

Hi,

It'll be in the expression window. Did you check expression window?

Hi,

The expression and variable window both are blank.

I again tried adding the variable to the expression window and as before it gives only the current value.

Is there a way I can add it to the Variable window, instead of the expression window?

Basically, I add all my variables, arrays etc in expression window and they all work fine. I've not tried variable window as expression window solved my purpose.

Hi Gautam,

I solved my problem on my own, earlier I was adding the entire array i.e "Voltage1[ConversionCount]" to the expression window which displayed as x= Voltage1[ConversionCount] in the expression window, which displayed only the last value.

Now I added just the name i.e "Voltage1" to the expression window and it displays as a folder with an expand option, with all the 100 values.

On a different note:

Is it possible to plot graph with float values.

Can you explain a bit about Silicon Real-time mode ? And when should it be used?

Thank you for your time.

Hi,

Yup, its very much possible.

Hi Gautam,

I tried plotting graph of the RMS array, which is float32 in CCS. But I get an error float is 16. Only unsigned type 32/64 bits are supported. Please find attached.

I tried selecting the complete array of 100 and then copy paste in excel, but only top 3 values are pasted in excel. I also tried import option in the expression window but can't get the values. Separate post on http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/298866.aspx

Thank you for the link, I will have a read through real-time mode.
