Part Number: TMS320F28027

Tool/software: Code Composer Studio

I set up a single time graph and also in memory browser, but the memory browser doesn't work.

I want to know what I did wrong.

    Emma,

    The graph looks like it is setup to continuously refresh while running. As the memory browser's refresh buttons are disabled I am guessing that your application is running when this screen capture was taken. Thus the memory browser it not showing any data but the graph will keep reading the value.

    If you halt the Memory Browser will refresh and show the current values.

    Regards,
    John

    I believe I know what is going on.

    1) I believe the value of Voltage1 is being used as the starting address in the Memory Browser instead of the address of Voltage1

    2) The rendering in the Memory Browser has been changed and something is going wrong with the display.

    Lets start with #1.

    If you enter Voltage1 in the Expressions view what does it show for the address?  Does this match with the address shown in the Memory Browser?  If not enter &Voltage1 as the starting address instead of Voltage1.  Below is an image that shows something similar with a variable "var"

    Now for #2.

    I was able to reproduce the ???? display if I changed the rendering in the memory browser to floating point.

    To fix this go to the down arrow on the toolbar of the memory browser and change it to memory rendering

    Then open a new Memory Browser instance by clicking on the new button on the memory browser toolbar.

    In the new browser that opens enter &Voltage1 in the start address box

    Regards,

    John

    Yes, it is confusing as to the rendering.

    As John said, choose the rendering. Instead of opening a new memory window, you can close the tab inside the memory window (there is a tab with title Data:0x890a - var <Floating Point> ). Close the tab there, then go back to the address bar and press enter again.
