CCS/IWR6843ISK-ODS: sprintf() function doesn´t work to print output in putty console

Tool/software: Code Composer Studio

Hi,

I am working with IWR6843ISK_ODS E2.0 sensor and 68XX_3D_People_Counting(also latest version 4.2.0) program on CCS 8.3.1. After put it running I want to print the output in putty/tera term console, so I used sprintf() function, but it doesn´t work (program abort). Without using sprintf() function program keeps running.

I declare peoplecont variable above.

How can I solve this problem? Or is there any other way to print output in putty console?

Regards,

Usama

Usama,

Tomorrow I will get my board to try this specific scenario, but the snippet of code you sent does not have any code that indicates the data is being transmitted via UART.

Also, the sprintf requires a lot of resources for stack and heap (not task stack or heap, but the ones set by the compiler tools). Please check the following article for details:

Hope this helps,

Rafael

Hi,

I see you reported using other relevant APIs (instead of sprintf) that should take you closer to actually transmit data via UART in the other thread you opened.

This thread will be closed then.
