CCS/TMS320F28335: GUI Composer V2

Guillaume CHIOCCIOLI

Hello,

First of all thanks for the answer, now it works.

I've a new question related to GUI Composer and also related to CCS:

--> I've a Param.c file in my project with parameters defined via a structure in a table. Exemple Param[0].pv_param.value

--> At the end of this file, there is the following definition :

#pragma DATA_SECTION(paramsCRC, "myProject_params");
const unsigned long paramsCRC = 0xB0955481;

It seems that the parameters are stored in the memory, somewhere.

I will, via the GUI i'm building, modify this parameters during the test on the hardware. I want to "save" the parameters in a file and load this file later when I will start again the GUI.

Is it possible ? And if yes, how is it possible ?

Thanks for your answer and time.

    I split this into a new thread since this is a new question and the previous one is answered.

    In order to bind widgets to variables in the program, they need to be global variables. I'm not sure if I understand what you mean by save and load the parameters from a file, but have you had a look at the examples in the GUI Composer Gallery. Perhaps the functionality you are looking for is shown in one of the examples.

    Hello,

    Yes I have global variables in my program and they are bind to widgets. What I'm able to do is to modify the values using the widgets.

    Now, I would like to save/export the values of the variables in a file.

    Next time I'll start the GUI, the variables values will be the default values. Now, I would like to apply the previous saved values from the file.

    Guillaume,

    All the demo examples we have are available in the Gallery.  You can use the ones available there as a starting point and build upon them. If you search for "save file" or something similar in the Search box, you will find an example called "XDS_SaveVariablesToFile" which I think may be what you are looking for.
