Part Number: TMS320F28335

Tool/software: Code Composer Studio

Hi. I am using TMS320F28335 and CCS v8.1.0.

I receive IMU sensor data by RS232.

I need to plot the data in MATLAB.

I want to write the IMU sensor data on .txt file.

So I made a simple code as below.

FILE* stream;

stream = fopen("data1.txt", "w");

fclose(stream);

But there is no txt file.

Excuse my poor English.

Hi,

Check the path of the file. It should be in the current folder where you are running your application. Also, you should check stream == NULL, if there is any problem in creating the file like you have permission to create the file etc.

Thank you Jha.

I tried 'stream == NULL' also.

But It didn't work.

How can i set the permission to create the file etc.?

And anything else?

Thank you.

Hi,

fopen returns NULL? If yes, then it failed to create the file. Please refer to the example here in the link.

Can you send you code how are you creating and writing file?
